Met my expectation
kade714 –
very strong signal. Difficult to set up p2p but that has nothing to do with the quality of the product.
Vic –
This modem works great. We can use several devices at once with no lagging at all
Customer –
Super easy to install and so far totally worth the money! Was tired of paying a monthly rental fee to our Internet provider for a crappy modem/router that kept dropping out. Our provider “tested” and said rental was running fine but we have seen such an improvement in speed and performance since purchasing this and making the switch about a month ago.
steve cow –
Works waaaay better than my old one…..very stable 🙂
Brian Herman –
Great cable modem and wifi router
Kenneth Coats –
it was grate
Richard J. Holmstrom –
I bought this during the annual Amazon Day and it was a great deal! The hookup was simple and I made one phone call to my internet provider (Brighthouse) to get it running on my internet service. Performance has been excellent through my whole house. I’d highly recommend this model as it’s fast and stable. I would prefer if it came in black (I’d rather have it blend into my AV stand – the white’s more obvious) but I’d still buy it again.
Mike M. –
One of the better modem/WiFi device I’ve had. It’s big but it’s powerful!
MW –
This was very easy to set up. The only problem i’ve noticed is that my wifi seems to be a bit slower. Still worth it.
Rob Font –
It’s perfect. So easy to set up. So fast and works throughout my entire home. Love it.
Customer –
It installed easily and has not let me down since I’ve plugged it in. It’s compact and doesn’t take up as much space as buying two seperate items. My last router and modem had to be restarted at least once a month and the router alone was over $200. It does the job well 🙂
Hunter A –
Works well so far but I had to look online for the default password because it’s motorola instead of password. So if you can’t login try admin for username and motorola as the password.
Customer –
Nice modem.
MD –
Be sure to check with cable provider. Regardless what the product states, TWC doesn’t support >100mbps for this model
Sheri Koprowski –
It works great. I research many makes and models and this fit what I was looking for.
DB –
Modem, wi-fi and router all in one! Works great for me!
Anne J. Geoghegan –
Used this for 3 months and it died.
JayC –
Prompt delivery, Super easy configuration and working like a charm.
Mike the Engineer –
The Arris Surfboard modem works flawlessly with our Cox Communications Internet and HDTV service. This particular modem was suggested as one that would work with Cox Communications and it has done so without a problem. I would not hesitate to purchase this, or any, Motorola/Arris modem because you will get a quality product.The only problem we experienced was the incorrect provisioning of the modem by Cox when they input the incorrect serial number into their system. I can’t blame Arris for Cox errors. Once the correct information was entered by Cox, the internet and HDTV service has performed without problems.
York S –
I bought this modem to replace the one provided by Xifinity. Unfortunately, it can’t do the job. It can only cover very limited area on the first floor, and almost no signal on the second floor. I had to buy an extender.
Customer –
Product arrived quick. Product worked as described. No issues. very satisfied.
James Hargis –
One of the best, if not the BEST modem/router i’ve ever own. Normally i’ll set up my modem/router and have to also connect a bridge for better connection speeds in the back of my house, not this time! I did anyway, just because i bought one the same time i bought this, and i didn’t want to throw it out, or not use it. But its not needed. This thing is a beast. GREAT GREAT GREAT connection speeds. I live in a 2500sq ft house the connection speeds are awesome all around the entire house even in the master bedroom which is in the deepest corner compared to the location of this modem/router. Definite must have if you need a two in one!!So far so good!!!I did go ahead and get the 2yr Square Trade Warranty, i’m hoping i don’t have to use it.
Customer –
Works Great!
BDRand –
Very happy with this modem/router especially on 5G. Set up was simple as I used all the setup info from my retired router. All my devices “see” my router as the old one with much improved performance. Range is very good as well.
Cheryl L. Fox –
Great product. Only drawback is that there is no outlet for the phone. Wi-Fi is much stronger now, even on the lanai.
Kiko –
Works quite stably, but range is not great. Need a range extender for my house, which is not particularly big.
Joe –
Excellent!
Shelby –
So easy to set up and Internet is super fast!
Mark S. –
The Arris Surfboard Cable Modem was a great replacement for the cable modem I was renting from my internet provider. It was easy to set-up and the switch over from the rental modem went smoothly as well. It is great to have two different bands to use: 2.4 ghz or 5 ghz.
Scott Price –
Works really well, and the setup was easy. the range is not as far as I expected, but it works well
John Burmeister –
It did just what we expected! Jack
grayteeth –
Has worked perfectly since I purchased it, glad I bought it without modem/router fee’s it’ll pay for itself in the first year. It also works better than what is provided by Comcast.
Hard to please –
Modem arrived on time and is working fine.
Brittney –
not compatible with comcast
Carissa Gill –
Works GREAT. Supper fast with even when streaming movies and playing games.
Wally S –
This modem/router was very easy to install. The WiFi signal is strong, reaching well outside our home. Adjusting settings is easy and well laid out. So far we’ve only had to reboot the router once.
MAS –
I wish it had USB port as well
John –
Product is pretty large but very reliable.
nhm –
It might be a 5-star product; however, since I got rid of the Comcast rental modem/router, my smart phone periodically informs that my wifi connection “may be dangerous”. Connection is definitely a higher bandwidth.
fred klitzka –
Excellent !
Tim Bridwell –
Great product. Easy setup.
C. Jacobs –
I purchased this based on the it having high power wifi, it is not as high power as I need.
Angry Ryan –
This is so much better than what Comcast provides, we now have 90 mbps speeds vs 45 mbps. And we are able to get a signal throughout the entire house. Should have done this a year ago.
Williamstown –
it was easy to hook up and has been flawless so far. No real problems to report.
Johnny_® –
Over 25,000 reviews! So just my quick 2 cents(I am reviewing specifically the SBG6782-AC AC1750 Modem/Wi-Fi Router):*First and foremost, remember – this is a router and modem in one, so for most cable internet users, you have to call to your service provider and tell them the MAC address of this product, so they can enter it into your account, before it can work properly. This is something you have to do each time you replace the modem, not the router. I had forgotten about that fact, and although the diagnostics showed it was sending and receiving data, I couldn’t get an Internet connection. Gave Time Warner Cable a call, and it was working immediately after. You can find the MAC address on the product box, inside the instruction booklet, and/or on the modem itself.*Once up and running, it’s been working flawlessly. I have the 100 Mbps down/10 Mbps up package, and Speedtest.net confirms it for both Wi-Fi and Ethernet connections(actually 118 Mbps down/12 Mbps up).*The IP/Web address to set up the configurations is 192.168.0.1 – the default username and password is admin/motorola.*The dimensions are quite big, at just over 10 inches long, just under 9 inches tall, and 3.25 inches wide at the base/stand, and just under 2.25 inches for the box’s actual width. It weighs about two pounds.
Customer –
Best router out there
Saad –
Great
JaneMargaret Riley –
Garbage! Save your money and buy something else. I used this to replace a stand alone modem and an Apple airport extreme for wifi. This unit constantly dropped the internet connection even for my wired devices and the wifi was terrible compared to the Apple airport. I tied to use it for a week and a half and have returned this for the SB6190. The SB6190 works great.
Chris Smith –
Boosted my download speed by over 30%. Well worth the investment in upgrading Wifi Router
E.F. –
Works great. I have only had to reset it twice in 4 months.
Diana Rivera –
great!!!!! beats the over $2k I have spent already paying COMCAST!!!
MARK RING –
Passwords inconsistent between quick start card and online manual – caused me start up problems. One on quick start card was wrong.
Customer –
great modem
Yesitsmedoug –
router performance seems to be good, speed seems to be good, connection seems to be reliable but the administration pages are the very worst I have seen in 15 years of dealing with home routers. ARRIS needs to throw away the entire management console and start from scratch to make it useful. I had to spend hours reconfiguring my wireless cameras to use a different network segment because this device CANOOT use 192.168.100.x for some reason. I lost probably 8-10 hours time messing with it reconfiguring everything again, then resetting then trying again etc. before finally giving up and unmounting all of my wi-fi cameras to bring to the router to reconfigure them.
paulicious21 –
I just got it today so take this with a grain of salt. I cant see a problem with it. I had a slight problem managing my wifi, no connectivity issues though. The default password for managing the wifi was wrong so I called in and they gave me the new one. It was then a piece of cake. Its fast! If I have any problems I’ll update this review. However considering the thousands of reviews this has I wouldn’t worry too much.
LeShortness –
My husband bought this back in mid June. It’s now 3 months later, and I wish he would have purchased a returnable one, or we would have had the problems, or returned it within the time allotted. For the past month, for sure, we Los connection about 4 to 5 times a day. Considering we finally dropped all cable TV, this was a bad time for this to happen. We have the modem/router in my son’s room, which is about the middle of the house. He will complain when it goes out, so it’s not just a distance thing….it’s just a piece of junk thing. Pretty sad when you pay basically a couple hundred dollars and you get a max of 2 months use out of an item. The dog chewed on the cord of our last one, and it still lasted us for a few years. I do not recmomend this item.
Floyd –
My internet speeds are noticeabley faster. We’re using several devices, three laptops, two tablets, two tvs, and phones. Bandwidth is not a problem.Before the upgrade there were a lot of pauses to load content. Spinning circles of death. Now it’s an enjoyable experience.

David Benoit –
Except for Comcast messing with my connection constantly, saving the $10 a month they charge per month for their modem is worth it!
Andrea –
This is a great router and modem in one. Unless you are doing really high tech things you don’t need the modem and router in separate boxed (I.e., if you don’t know what I’m talking about you don’t need it).I shopped around a lot and asked friends who know more about tech than I do. One recommended this router as a middle tier (upper price point of the tier) and I’m very grateful. We get signal everywhere in our house and have 2 stories.
orlando –
awesome product and service providers modem paying for 50 megabytes and only gets 38. router needed to buy a 100$ extender on top of that. bought this modem/router gets 60 megabytes and gave away my wifi extender . easy to set go to provider and have them register it for you go home and plug-in thts it.
Tim –
This is my first experience with this product and so far it’s working as expected. I have noticed the wifi range is better than the Motorola we replaced. I would recommend this product.
Bub61 –
Got my internet running faster and smoother than other Comcast modems. Worth the extra money for a quality product.
JB USA –
Wifi is is dying all the time is kicking out all devices, some times only from 2.4GHz, some times all, modem is ok but looks I need get separate wifi router. My kids & wife calling all the time and asking how to fix internet. I reset it to factory settings and still I’m having same problem. My friend have same problems with this model(SNG6782)
G. Powers –
It works well and is very appealing to the eye as well. A bit large but I’m not picky.
Abigail T. –
Great product. Bought it for Comcast internet service and it works great!
Marie Hermans –
So far works as well as the original Modem I had for internet, cable and WiFi. Great customer support. Friendly, helpful and concerned.
Mr. F. –
Although packaging clearly states compatibility with TWC and download speeds up to 343mbps, you can not get any download speeds greater than 100 Mbps with TWC. Not sure if this is all locations or not. Check with service provider before you buy. Actually, I did check with TWC before I bought this last year, but when TWC upgraded to 300 Mbps service there was no mention of incompatibility. Current TWC web site does not show SBG 6782 as capable of higher service. Also, recent experience with this modem has been very disappointing. Numerous dropped signals from wireless usage. Constantly getting “connection lost” messages even when working in the room with the modem, I question its range. Trouble shooting calls to both TWC and Arris yield mutual, and unresolveable, finger pointing. It’s the cable service, it’s the modem. Consumer looses!!!!! Very unhappy with both Arris and TWC.
RodE1944 –
Easy to install & use. So far, so good.
Pam –
works great with comcast cable for me.
Joe –
Constant problems with the 5Ghz band disconnecting, needing to shut it off then re-enable it. Stays connected for some time and then needs to repeat action. Maybe ARRIS needs to send a firmware upgrade?
92Roadster –
great router/modem with LOTS of capability! I only use it to make 50% of its capabilities, but this modem/router can do a ton of stuff and I no longer have to pay the dumb cable company a rental fee every month to use theirs. 10 months of no rental fee and you’ve gotten a return on your purchase. Every month after that is just saved money going in your pocket.
colieo123 –
This is a handy wifi cable box but does not include a plug for internet phone service so I had to return it. It is probably my fault for being so unaware of the technology but maybe the product description should say somewhere it cannot accommodate phone service if you have a tv, phone, internet bundled package. The return was easy but cost over $20.
LARRY –
Works great, plus saves me $20.00 a month.
CS –
Great router and modem. Works on Comcast and Time Warner. Been very pleased.
Corina Rayas –
Better speeds than cable leased modem! Why was I paying extra to lease?! Very happy with this modem.
sparkey –
Excellent product works really well far better than what I expected works awesome with time warmer cable in NYC
R. K. Young –
easy set-up, but the main issue I am having is the range of the wifi signal is very limited. it is possible that the settings can be configured to remedy this issue. If I can configure the settings to do that, then I will revise the number of stars given with this review because it is otherwise a great modem.
Yoselin –
We were having issues with wifi dropping and buffering CONSTANTLY. I had contacted the cable company thinking it was the internet service but they came out and said the connection was fine. Turns out it was the wireless router which was bad. Once I installed the surfboard I was back in business. I can actually watch Netflix, Game and download on different devices at the same time. Prior to this I was buffering in 480p on youtube which was extremely frustrating.The price was steep on this router, there are cheaper option out there. In fact I could have got one from the cable company for cheaper. I didnt want that. I wanted a high quality router and this is what we got with the ARRRIS Surfboard.I would definitely recommend this item to everyone that is looking for a modem/router combo who is sick of slow wifi due to bad equipment provided by your cable company.
Ken –
works OK, need to put a fan on it, it gets hot it wont last long like this.
Julio –
Delivers very fast wifi and looks very good on my wooden desk. It’s easy to install, no prior experience needed, just follow the instructions. It’s been two months and it hasn’t given me any problems. I would highly recommend this product.
timmy v –
Serious connectivity issues.
KB –
Modem/router works well. It has increased my internet speed and broadcasts to all the dead spots I once had in the house. I highly recommend this product and it is priced right.
Edward W Gibson –
supper great
Black_Snot –
Arrived on time. Item as described. No problems after 1 month of use.
cjj –
Easy to install and great set up. Has performed very well so far.
Chad R. –
I am able to achieve 200mbs download over wifi with this! It’s great and it works with Comcast boxes!
suresh –
One of the Ethernet port stopped working all of a sudden. Speed and reliability of the network is good.
Adrian –
I get a very strong connection and it never drops.
Gigi –
I’m not too tech savvy but this was fairly easy to set up. I called tech support with a question and the representative was super helpful. The modem works great and am happy with my purchase.
A. Kozbial –
It simply works great and was super easy to install and set-up with Comcast.
ESL –
Printer no longer picks up signal automatically. New devices require me to unplug then plug the router for them to pick up the signal. No noticeable improvement with speed compared to the 5-year-old router I replaced.
PickUp –
Works great, easy setup, and good customer service. This was the latest advancement in cable internet modem routers when I purchased it. I used it for 6 months without issue then changed my internet service to dsl. This is a cable ONLY modem and router. My local cable, midco, accepted this as a modem. I kept it just in case we switched back because it worked so well.
tonsofdays –
Works as described. Easy setup. Good value
Jill B. –
I am at a Starbucks as I write this review because we cannot connect to the internet!! The technology with this device is so antiquated we can’t do anything. We increased our data with Cox and it’s been non-stop problems–daily re-booting doesn’t even help anymore. We usually have two phones, one laptop, and our Roku going at once (in terms of internet usage) and this thing can only handle one device at a time!! Additionally, the range is so poor you basically have to sit next to it to get more than one bar. I would say 600 feet TOPS! If it was 2011, I would tell you to buy this, but it’s 2016 and this thing needs to be retired.
Customer –
This device exceeds my expectations of quality and wireless network operating system.
PMawyer –
After having this modem/router combo for a short time, I have noticed that connectivity randomly and frequently drops and some devices no longer are able to connect to the internet. I have experienced situation with VOIP phones where the SIP server cannot be found randomly, or I can get dial tone on the phone and calls can come in, but audio stream for incoming calls do not work, so the calls are basically useless. Brighthouse has checked signals and they show that they pretty much can’t be any better. I have seen many comments on this combo modem/router outside of Amazon at this point and the comments I have seen on here also relate to what I am seeing. It’s pretty disappointing that this piece of hardware has become such an issue. At this point, I’m not even sure I can get a replacement anymore and will need to buy new equipment. Starting to get fed up with Arris products.
L D. –
Range & strength of wi-fi could be better, 30 feet from router signal starts decreasing and dropping
mary mckinney –
Works great. Any questions that I have for this item; I call Motorola and they help me out with no problem. They are so nice and polite; always there to help out. Have had no problems with this item itself; just had some questions hooking it up etc. This is the second one that I have gotten like this. I just upgrade
William –
Bought this refurbished and it seems to work great. Gets the signal to where my older modems/wifi routers could not. It pays for itself considering the cost to rent a modem from a provide is $10-15/month usually.Highly recommend as a great modem/router combo with great speed and signal strength.
Elena –
I was afraid that I would have to deal with customer service to configure this baby to its best but it was pretty much plug-n-play.Xfinity recognized the device instantly and activated it just like that.The Arris software for configuring the network is pretty good and although I’m an advanced user I felt like a lot of non advanced users would have found it easy to use too – it has a brilliant configuration wizard that walks you through the most important items very intuitively. Very very good for such a widely configurable machine.
KateinNY –
Worked ok at first. Stopped receiving internet signals after 3 months. Totally useless, and can’t return it. Hoping warranty can help me out.
Edward Z –
GREAT
cefu63 –
Not overly impressed. Connection speeds worse than before on all systems with 2.4GHz. PS4 lost over half it’s connection speed. I had high hopes for this but looks like I’m out $150 for mediocre results. I will say that set up was a breeze.Update: Now nothing can connect to the internet for longer than 1 to 3 minutes without being kicked. Complete waste of money. Do NOT buy this expecting for an easy option. Ended up buying Netgear cable modem, wireless router and wifi extender. Had all 3 up and running within an half hours with over double the speed for most of my devices. All 3 products cost me less than the Arris SURFboard.
Thevaluator –
fast. good value. no problems. way more economical that paying the cable company to rent one. If only my laptops were as fast as it’s wireless…
M&M –
We replaced three devices (Arris SB6141 Cable Modem, Netgear WNDR4000 WiFi Router and Actiontec MoCA Router) with one device. This modem/router uses a single 110 plug (not a wall wart). This upgrade added 802.11AC and uses less total power, coax and network cords than the components it replaced. My Only gripe is the guest networks happened to use an IP address range I wanted to use (192.168.2.xxx). However, I just fixed a couple devices with fixed the IP addresses and everything works great. The MoCA is compatible with TiVo Roamio DVR and TiVo Mini’s. Our Honeywell thermostat, iPhones and iPads all connected automatically when I edited the WiFi setup to match old router. WiFi is now much more stable with large file transfers than the older Netgear Router it replaced. The TiVo Roamio needed a reset of it’s network settings to pair up to the new MoCA, the mini’s just had to be rebooted. We’re a month in and no reboots to this router have been required. What a difference!!
Sarah M Applegate –
plug & play. great product as advertised. it’s also saving us $10/month on our cable bill as we no longer have to rent modem from time warner.
Anne Triplett –
Works 92% of the time perfectly…..damn do I get pissed the other 8% of the time.Not a bad price for something that pays for itself
Zeus –
Dropped internet connection……that’s what initially was happening when I got this gateway fired up.Having read the reviews both good and bad I weighed my options. For the money the Arris SBG-6782AC seemed like the best alternative to paying the $10 monthly rental fee from Comcast. While it’s not ideal to have the modem and router contained in one unit I took a chance because DSLreports said if you must purchase a wireless gateway that this is the product you should get. Here are some things that I did to get everything up and running the way it should.1. The installation and setup process of the SBG-6782AC went off without a hitch. If you follow the instructions in the quick start guide setting it up is a breeze. With Comcast you can simply plug your computer into one of the ethernet ports to setup and activate the unit. Opening a browser window will take you to the Comcast equipment setup/registration page. From there it’s just a matter of following the on-screen instructions. Most importantly Comcast will update the gateway’s firmware…..This is very important because you cannot perform this action yourself on this unit. As of 10-16-2016 the most recent firmware version appears to be D30GW-EAGLE-1.5.0.0-GA-07-NOSH. Knowing this is important because there are very few resources available online to tell you if your gateway firmware is up to date…..The manufacturer’s web site does not give you this information…(it might but I sure couldn’t find it after digging around for a while) An out of date firmware version will cause headaches throughout your network.2. Not only does the software in the gateway need to be up to date but all your wireless wifi adapters must have their current drives installed too. My laptop has an Intel(R) Centrino(R) Wireless-N 100 wifi adapter that, according to the hardware manufacturer, will not be supported for much longer. I actually found out by mistake that my adapter driver was not up to date. OUT OF DATE WIFI ADAPTER DRIVER SOFTWARE IS WHY MY INTERNET CONNECTION WAS DROPPING OUT. Updating the driver through Windows did not work. Windows was telling me that my computer already had the most current version of the driver software….The date on the most current driver, according to Windows, was from 2011. *******Here is what I did to fix that issue****** (NOTE: Your computer should either be hooked up to the gateway via an ethernet cable or connected with some type of USB wifi adapter so you can still have access to the internet while the built it wifi adapter is being updated) Go to your control panel and bring up your device manager. Select “network adapters” (write down the name and model # of the adapter for future reference) and right click on your wireless wifi adapter then select “uninstall”….Once the wifi adapter is uninstalled, right click on any category in the device manager and select “scan for hardware changes”. After scanning for hardware changes your wireless wifi adapter will show up as an unknown device in the device manager tree. Now you need to get online, enter the name of your wifi adapter and do a search for its driver software. Once you’ve found the correct version of the adapter’s software for your operating system (Mine is Windows 7) go ahead and download it…..then install it. This will either automatically update the wifi adapter’s software or make it available to you to update the driver yourself. If you need to do it yourself just right click on your adapter’s name in the device manager tree and select “update driver software”….It *should* find the new software and install it without issue. AS IT TURNS OUT THE NEW VERSION OF THE WIFI ADAPTER’S SOFTWARE WAS 4 YEARS NEWER THAN WHAT WINDOWS WAS TELLING ME WAS ALREADY UP TO DATE.If you are having problems with dropping internet connections give this process a shot……I accidentally found out that this is what the problem was. Maybe I can save you some time by pointing you in the right direction.4 stars for the equipment which works very well even all the way out to my man cave (shed) which is 100 feet away from the house out in the backyard….Minus one star due to the fiddling around that I had to do to get everything working properly. I consider myself very tech savvy but if you are having dropped connection issues it can be time consuming trying to get all the little bugs worked out. Hopefully my review can save you a lot of the time that I put in getting things working smoothly. UPDATED SOFTWARE IS VERY IMPORTANT FOR THE OPERATION OF THE SBG-6782-AC.Update 11-3-16: My connection speeds were pretty poor with the wireless N card in my laptop. I swapped out the card with a dual band model and my speeds increased significantly. The router really moves along in the 5 Ghz range. The gateway has worked flawlessly for a few weeks now…..It’s never needed restarting and has never dropped the internet connection. If you keep your drivers up to date I suspect this product will function as advertised. I am very happy with my purchase.
M. D. Grooms –
Less than 1 month past warranty expiration, WiFi cuts in and out. Until 3.1 cable modems appear, stuck with this nonsense.
TLR –
THIS MODEL IS OLD. AT LEAST 2013 This device worked perfectly in the beginning but after 5 months it drops the internet every few minutes while I’m online. Good going Amazon- all of the reviews posted at the top of the page are all good reviews of this piece of junk FROM 2013! Get past those and you will see of all the bad reviews and the dropping issues for the device. Great. I bought 2….
dgreen1069 –
This thing works with my Xfinity internet, but it certainly does not wow me with it’s performance. I’ve lived in my house for 15 years and have always had fast internet (both Comcast and Fios). I’ve had several modems and routers over the years but they have always been rented. I recently switched back to Comcast for internet and wanted to save money on equipment charges. I bought this unit on sale based on the thousands of reviews on Amazon.The good – the unit started working as soon as it was installed. I ordered it before Comcast came out to activate my internet, so it was installed and setup by their technician. He called Comcast and dealt with whatever is necessary to activate a modem with them.The bad – it seems to hang up on occasion and require a reboot to function correctly. The bigger issue for me is that the wifi range kinda sucks. I’ve never had connectivity issues in my house before, but the wifi coverage with this unit on my second floor is dodgy at best. If I could do it over, I would definitely NOT buy this unit again. The combo unit that I had from Fios was FAR more reliable and offered significantly better wifi coverage.

Product is good. It works as advertised.

Worked just as expected once it was set up. I would recommend calling Internet provider instead of trying to follow any online instructions.

Excellent product!

This all in modem is awesome! It handles our cable modem and wi-fi needs in my household. You can even switch it to 5G mode! Anyways, I was going to buy at Best Buy and price match but they did not carry this model in stock so I ordered it through Amazon! It was worth the wait only 2 days!

Disclaimer: This is a review of the product only. Arris customer representatives have been extremely helpful and very courteous and they tried their best to help me resolve the issue but to no avail. That said, their product exchange policy is that I ship the modem first paying for shipping and they ship a replacement modem back after 5-7 business days after they have received my modem. They expect the customer to stay without Internet connection for a couple of weeks. Wonder who in the company came up with that brilliant idea!OK, about the product, where do I begin? The problems started on day 1. The WiFi connectivity is extremely unstable. All devices (every single one without exception, iPhones, iPads, laptops, printer, TV set up boxes, you name it) drop Wifi randomly and either reconnect on their own or you have to manually reconnect. Oftentimes, the device is/seems connected to wifi but the page does not load at all. It happens in both levels of our house and so distance from the router does not seem to be an issue. I did call Comcast as well to see if this is an ISP issue and everything looked good on their side and they pointed me to contact Arris.I made 4 calls to Arris two of which were detailed troubleshooting exercises none of which helped. They checked pretty much everything from SNR values, enabling/disabling b/g/n modes, changing BW settings, changing channel multiple times after scanning nearby wireless APs in the area for both 2.4 Ghz and 5 Ghz, enabling/disabling SSID broadcast, changing wireless security and encryption settings (did not try unencrypted mode and I don’t care if that works because I will not be using it that way), enabling/disabling WPS, enabling/disabling airtime prioritization, enabling/disabling band steering, trying different positions for the modem (away from speakers, 2.4 Ghz phones) etc. etc. (Arris does not do Firmware updates. They rely on the ISP for this.)For comparison, we had Verizon FioS for two years at the same location before (leased their modem) and never had issues; not one! It was plug and play and it worked. I never had to login to the router in two years.I cannot recommend this product in good conscience. I do see lot of good reviews here and I may have been an unfortunate recipient of a defective unit but having gone through all this, the product does not deserve a good review for sure.PS. I have already tried multiple times to submit this review and it does not go through because of flaky Wifi! Need to keep trying until I succeed…

Our TV and internet provider was charging $10 per month for the modem and another charge for router (we had our own). Now saving enough per month and will pay off the Arris in a year. The reception is better and the internet speed test has risen considerably.
Jj –
Great product!
Clive Walden –
Effective modem/router but I am deducting two stars because:1. It restricts the NAT IP ranges you can select.2. The coverage of its WiFi options is very poor. I ended up buying a dedicated AP (access point) that covers far more distance than the ARRIS.
JWow Robotx3 –
UPDATE:Problems with my ISP has smoke screened my analysis. This router is fine, I have added two stars for now(for a total of four). It seems as though my service provider, or possibly faulty wiring, is the real culprit and the source of my problems that I have been having. I refuse to give the full five stars because I am powerless to update or not update the firmware.–This cable modem was OK until it broke. If I could go back I would probably keep my routing and wi-fi-ing capabilities separated. Currently, this thing only allows one computer in the house to connect and the administration page no longer functions. I’m afraid I’m going to take it off of life support.

Great replacement for rental from Comcast
Customer –
I bought this device thinking that an expensive combined unit would work really well with Comcast Xfinity Internet. My internet would show as connected but no pages would load on both 2.4 and 5 Ghtz. The troubleshooting I went through was all of the forum recommendations to adjust the setting and nothing worked. Avoid this product at all costs. Additionally it took me a couple months to finally give up and I can now no longer return to Amazon.I switched to a separate modem and wireless router and my signal has been strong ever since.
mappam –
It was easy to install, has a strong signal in every room and hasn’t required a single reboot, unlike replaced the Xfinity unit which was very unstable.
Kelly Gray –
This router has made my life and wi-fi so much better. Works very well with little, if any, dropped connections. If you have a smart home and all tech in your house, this is the way to go.
Robin M –
Bought this because it was on the Comcast list of accepted modems and had a high rating. Unfortunately after spending hours on the phone with both Arris and Comcast, we could not get it to work properly. We had to conclude that there was a firmware issue and the modem was not fixable. I had to request a refund.
Brian –
I purchased this at the end of April and have had several issues. It does not seem to like Wide Open West. For some reason I get locked out of my SURFBoard. I’ve spoken to tech support and they are stumped. Can login with Safari, but once the initial configuration takes place, cannot use Chrome, ID, for FireFox. We’ve cleared browsing history, etc. If I disconnect the Cable from the modem I can get in with those browsers. Reconnect the cable and I’m locked out. Tech Support is fairly stumped and recommends having WOW re provision the Modem, basically remove it from my account and then set it back up. Their tech support is helpful, but seems like the modem should work better.The other item I noticed is that before I used a Netgear router/ wireless switch. It had much better range than the SURFBoard. I’ve had to go out and buy range extenders to cover what Netgear could do by itself. So overall it’s ok, but based upon my experience I feel like there has to be something better out there.
J.S. –
Recently purchased this modem and wanted to use it a week or so before submitting a review. I am very pleased with the performance. So far I am using one of the four ethernet ports (soon to be more) and both wifi bands. I have yet to see a noticeable difference between the two bands, as far as speed, but my internet only provides a best speed tested at 54mbs. I live in a small two story house and signal strength is sufficient throughout. I did load it up with two cell phones,one lap top and a tv all streaming at the same time as a test. No buffering issues. I also bought it “used” through Amazon warehouse for half the regular price. Condition was very good. I am very pleased with this purchase. No more rental fees to TWC.

i just received it not sure if it works yet but when i got it the box has been opened and there was a plug missing from it not sure if it was a return or not I have to get a plug and try it when my new internet that is being installed box had been re taped so i hope t works

I was looking to set up a wireless network for my parents and in the pursuit of simplicity I opted for the SBG6782-AC. I’m writing this review to hopefully save someone else from making the same mistake.The modem is fine. The wireless router is where everything falls apart. LAN throughput on the A/C network is slower than on my previous N network (Asus RT-N66U). The range is also disappointing and the connection frequently drops. I have to power cycle this device multiple times a week.The firmware is entirely under the control of your service provider (in this case Comcast), which is another downside.I should have trusted the strong feeling of trepidation I had about buying an AIO device. The “simplicity” is not worth the trade-off in reliability and capability. Stick to a plain Surfboard and the router of your choice.
Jason –
I bought a different modem on Amazon and had a lot of trouble with my connection for about a year. Decided to buy this one instead and it worked perfectly immediately. Like a router should. Great speed now.Both if the modems were on Time Warner Cable’s list of approved devices, but obviously I recommend this one.
Sandeep Saksena –
Works very well and boosted my internet speed by almost four due to the four channels it uses to communicate with myTime Warner provider network. Having some issues getting the 5G wireless network to remain stable even after rebooting a few times hence removing a star. The 2.4G works flawlessly.
codey koble –
Absolute garbage. Bought this to replace a 4 year old surfboard and also gain the dual bands. The wireless is horrible, anywhere over 20 feet away and we have to disable WiFi on our phones and tablets. I’ve tried many different channels on the router and three different spots in the house to set it up and it’s made no difference in performance. After 5 months of use I’m looking at other brands to replace it.
Bob P –
Works great!
AP –
The signal on this device is sub-optimal given the price and the ratings. I would say it is on par with a high level N router but with the AC price tag. Plus it runs very hot. I found myself having to restart the thing at least every other day to restore the bandwidth speeds back to normal otherwise I would be surfing the web with a 1Mbps connection directly connected over Ethernet. Ridiculous. I give it two stars since on rare occasions it would work as advertised. And of course I thought eventually it would start working and now it is passed the point were I can return it.I emailed the company ARRIS to ask if there were any firmware upgrades that might help boost the quality of the signal and the consistency. Their response was that they do not have any upgrades available nor will there ever be any since this device is considered legacy and is no longer supported by ARRIS.Very Disappointing. It’s a shame that most of the products on amazon are bad quality items and are really just scams to get your money. Both amazon and 3rd party sellers know that the percentage of people who actually return defective/unusable/sub-standard products is very small in comparison to how many people are like me who think about returning it but end up waiting to long and having to swallow the cost of a useless piece of hardware or whatever it may be. Not to mention half the time when you are purchasing a “new item” it comes in second hand re-packaged box and has clearly been used and returned already. That one really gets me upset.

Does not work as expected, slow.

The modem works as expected when reading the feedback comments. A great product at a good price.
Customer –
works great! purchase your own instead paying expensive provider rental fees!!!
Customer –
Arrived promptly and worked great! I did have an issue with Comcast when coupling it with my account, there were several serial codes on the device so I had to find the right one. Once I found the right serial number it was good to go.
Tony P. –
got tired of renting lame modems from my Cable Provider. My speed increased by 3x with this unit. Well worth it. Great price too
K. Huffman –
Got this to replace the crappy router that Comcast supplied to me.This is extremely fast, both wired and wireless. Setup was very easy, and activation through Comcast was easy as well.Wireless can handle several devices at once,. Well worth the money, especially since now I save 10 buck a month on my Comcast account.
ganga padmesh –
Good.still working.
alnemir –
Bought two of them: one become completely dead less in 2 months, another one lost WiFi. ARRIS has declined its so-called “2 years warranty” on the basis of “bought not from authorized dealer”. Its quality depends of there you bought it. They even do not respond to Better Business Bureau. BEWARE!
K. C. Martel –
Modem got up in running on Xfinity in less than 10 minutes, It loses a star however as the password tp manage the gsateway printed on the manual is WRONG! I guess this is not uncommon, my user name was admin and the default password was ‘motorola’ not ‘password’ like the manual said. Annoying!Thankfully this website addresses that issue:[…]
Nara Vijay –
No issues so far!! Works seamlessly with comcast and am getting a speed of 120Mbps with it.
David –
Works perfectly, easy set up and immediately accepted by my service provider.
Margaret Murphy –
Not as strong reception as I had hoped. Maybe, there are other factors
Tropigal –
The worst one I’ve ever had. Constantly dropping connections, then it’s difficult to reconnect. Bought a range extender thinking that would help. I had never needed one before but thought I’d try. Didn’t help because it kept dropping the connection to the extender. It was sitting 20 feet from it with direct line of sight. Gave up and bought a TP Link Archer. Now I can connect anywhere in the house and do NOT need the extender.
Rebecca Becerra –
DO NOT BUY. Instead get the NETGEAR AC1750 (16×4) Wi-Fi Cable Modem Router (C6300). Initially, I liked the white, sleak look of the Arris Surfboard SBG6782 along with the relatively good Amazon reviews. First one I got was completely hosed; kept assigning an IPv4 address to the IPv6 setting. Returned it for a replacement and got the second one it up and working… for a day at the most. Wi-fi signal kept dropping, range was horrible, and the worst part was I would be connected to the Wi-Fi but my devices would show as No Internet Connection. Power off/power on of the Surfboard would resolve the issues for a couple hours, but then they’d come back. Just horrible. Finally read up on Amazon reviewers who had the same issue with the Surfboard and they pointed to the Netgear AC1750/C6300 combo. I bought the Netgear and haven’t had any problems with, works awesome. Do yourself a favor and just get the NETGEAR AC1750 (16×4) Wi-Fi Cable Modem Router (C6300) for the couple extra bucks.

Constantly loses connection with our devices. We have had problems with our phones, computers, direct tv, etc. Do not recommend buying
Candace L. Brown –
Gave us a completely different brand plug for the router. It has a different adapter and says Belkim on it. It clearly does not go with this router.

Product as description and in time
Amanda Gobert –
Works great!!

Easy setup. I’ve had it for a few months. We haven’t lost a connection yet. Speed seems fine.
John M. Scott –
Works great, easy set up. Speeds on Cox are significantly better.
Steve –
It works as described and I get the advertised speed by my ISP on my hard wired computer. However on my WiFi device’s it’s a different story! When I use the surfboard’s router I get 66.08 Mbps down and 12.39 Mbps upload. When I connect my Linksys router to the surfboard modem/router I get 98.74 Mbps download and 12.09 Mbps.
Customer –
terrific
Matt –
Constantly disconnects. ARRIS support is no help.
chris –
Well I’ve had this modem now for over 2 months now and it has worked good up until I connected my modem to my PlayStation 4 with the either net cable it disconnects after a few minutes of connection. Does someone have any suggestions
Brittany –
So far so good. My last Arris Surfboard modem/router lasted about 3 years. Hopefully this one will at least last the same.
Customer –
Good product.
J. Cullinan –
Decided to ignore the warnings about buying a combined modem-wifi-router and got this. Worked fine for about a year. Now can’t get more than 7 mb speed on the wifi, despite getting 110 mb from the ethernet connection. I’m now forced to go buy another router. What a gigantic waste of money.
Spencer Roll Tide –
great modem for mediacom and even has moca
brandon –
Works perfectly, I will start purchasing more from Amazon I have my eye on some stuff
FreeThroatHugs –
For someone to plug and run this is good. For anyone who wants control over thier network this is a TERRIBLE purchase.
Marc F. –
For the reasonable price, ease of installation, and consistent connectivity, this is a great combo(cable modem/wi-fi router) package. I bought this to replace an earlier Arris SURFboard (model SBG6580) which had constant wi-fi connectivity issues. The documentation (both manual and online help) for setup and web based Manager (router admin tool) has been helpful and instructional. It took me about 15 minutes to replace the 6580 with this 6782-AC and haven’t been disappointed with its performance yet. Kuddos to Team Arris!
Customer –
Easy too hook up works fanstatic! Very please with my purchase!

So far, great bandwidth and dual channel is nice for my 2 story. No complaints. I want to get online though to change the password and wifi name.
Customer –
It works save 10$ a month.
Andrea J. –
Not happy with this modem/router.1. The range is horrible. We used to be with Verizon and had an 8 year old wifi router that would reach out to the workshop with no problem (only about 100 feet away). This one is very weak2. The wifi doesn’t work very well, even when close to the Arris. We have iPads/iPhones and they would show that they were connected to the wifi but nothing would load. I had to bring an old router from work that I don’t use any more and set it up as an extension to the Arris so we could get more consistent wifi.3. One of the Ethernet ports doesn’t give consistent connection. I hooked my laptop up to the Arris directly with an Ethernet cable because the wifi wouldn’t work and the connection pulsed constantly! I could see the Internet connection in my task bar going in and out, in and out.We’ve lived with this for many months because I am sooo upset that I spent money on a device that is horrible. I just grin and bear it. I hope to be able to buy something to replace this for Christmas.
Adam –
works great for comcast
Lydia –
Works fine for wired connections, but won’t steadily connect to any wireless device.I have troubleshot all the devices and called and talked with the internet company to no avail. After 2 weeks or so of it sometimes working, sometimes not t now just won’t connect at all. Such a disappointment.
Amy –
I purchased the surfboard with high hopes for fast internet. The surfboard arrived and was very easy to setup, even with xfinity. However upon plugging the unit in, I immediately noticed a very high pitched frequency noise. It was painful to hear, and it actually was distressing my two dogs. They became restless and continuously were panting. I called customer service and ran through the gamut of trouble shooting they offered. The basic plug, unplug, factory reset and still the noise persisted. The only time the noise was not present is when the surfboard was unplugged. Also if multiple items connect to the surfboard the frequency would change pitches as it was further loaded. Customer service then said that it’s probably my wiring. SERIOUSLY??? Even though I’ve never had any issues in the past with any other router/modem combo, or any other electrical item. They were willing to ship me a new one at my cost, after they received my ‘defective’ one, again at my cost. And I would then be without internet for several weeks. RIDICULOUS, and lousy customer support. A simple google search on the noise issue resulted in MANY complaints of the same nature yet customer service had ‘never heard of it before’. Apparently they aren’t too concerned with return customers. If I could give negative stars I would. BUYERS BEWARE!!!
brian lakatos –
Works on xfinity perfectly
Mario A. –
Judy got off the phone with cable company because of an Internet speed issue. This modem was tested at their facility because they use this type and it only works up to 100 megabytes not the 300+ it claims. So I bought this in May 2016 had service running at 50 megabytes went to upgrade to 300 megabytes and surprisingly doesn’t even give me over 70 megabytes. So looking to see if I can get help from this seller I will keep you posted.
wen –
So far so good for a couple of months
Jessica M –
We purchased item with anticipation of having a new internet company coming out to connect internet last month unfortunately due to permit setbacks we didn’t get internet installed until yesterday and the brand new modem is BAD and defective!
Dee Cee –
Fair warning here. Do not even consider buying this product to use with Comcast, although it is an approved modem/router by this ISP. Very rarely do I have such a level of disgust with a purpose but have to do so in this case. Wish I could even rated it even lower.It has given me lots of grief; connection to the internet keeps dropping, even when my laptop is linked by directly vide Ethernet cable. My Amazon Fire Stick and Microcell (connected vide Ethernet cable) will not communicate with the modem router (can see them on my LAN but these devices were not able to connect with the internet). The MOCA network cannot be established.Have worked with tech support at Comcast, Motorola, ATT (for the Microcell) and Amazon for the last 8 months, at the very least, without success.Looking to junk this expensive piece of hardware.

Seth Cosby –
Easy to set up. They also have a great customer service line. I had a very unique problem that they sere able to fix in just a few minutes. I have had other routers where it was necessary to restart the modem or router fairly often to get the internet running. I have had this for months now and have never had an issue.
Customer –
Great connection, so far. Works very well with Comcast Xfinity.
Brian M –
I’m sure it works great on some internet providers but buyer beware. Constant drops made it unusable with Xfinity/Comcast. Arris tech support could only offer the suggestion to try different “channels” and they claimed interference from my printer or neighbors wifi was a problem. Two separate calls and that was their only answer and they had no other suggestions. Went to Comcast and got their wireless modem, no problems with their hardware So, life lesson learned and now I have a $150 paperweight. Maybe this modem could have worked with hours of research and tweaking. Not a user experience I’m looking for. Recommend you read reviews for success stories with your service provider.
P G –
Exceeds expectations! So much better than the comcast cable modem it replaced, it isn’t funny. My only regret is not changing to this sooner. Don’t miss paying comcast $10/month for a piece of equipment that in hindsight seemed set to run at half the speed I was paying for!
Bassin Guy –
Purchased this modem with router because I was moving and getting cable service from Comcast. Setup was easy and it seemed to work OK at first but then I kept losing the internet. Called Arris support and after having me run some tests said it was a Comcast problem. Called Comcast and technician spent a long time checking cable and changing connectors. He even ran a new feed under my house but problem persisted. Finally he changed out the modem to a Comcast rental and everything worked fine. Returned the Arris modem for a refund and purchased another brand modem and it too worked great. Comcast charged me for the service visit because the issue was in customer owned equipment. Thanks Arris.
Marko –
Can’t complain! Working so good so far without any dropped of connection (except when there is issue from provider of course), which is pretty rare for these Modem/Router combo.

Tech support was great. I had a issue with my cable connection. They were very helpful. The modem works great. Nice strong WIFI signal.Connected to Comcast with no problems.
Customer –
While product is better than what was provided by Time Warner the product still does not deliver the advertised speed. Looking to see if performance improves with Google Fiber.
Customer –
didn’t work. constantly dropped the signal and would have to do a factory reset. Spend more time that I cared to on the support line and dealing with the ISP to try to solve the issue. Replacing the gateway solved it and so I returned the Arris.
Samantha Alarcon –
This router is AWESOME!!!! I love the speed of our internet now. We got the cheapest internet that Time Warner (now Spectrum) has to offer, but this router/modem has made it into a higher speed than it’s actually supposed to be. My husband is playing X-box online while I write these reviews online and we never have any problems. This router is well worth the money.
Curtis Killian –
good
Katey Pooh –
I can’t begin to talk about all the specific technical specs of this product. But I can tell you that it works great, the guy who installed our internet said this was the best one on the market and it’s easy to set up. Great product and it was compatible with our internet provider.
