After having the Orbi for a little over six weeks now, no complaints so far. It does what it is supposed to do. The install was relatively easy no headaches at all. Good router!

My husband and I were renting a modem from Comcast for about 2 years. We finally decided to buy our own. Man what a difference! Immediately after we set up our Nighthawk we noticed a huge difference in speed. We are so pleased to have bought this modem router. It’s got a great design, easy to set up, easy to make changes anytime. We have about 8 devices connected to it and it works great no lag or delay of any kind. I would recommend this to anyone. I wish we would have switched over sooner.

I was attracted to this model because it is both a modem and a router, which of course is super great because it saves space. I used to have to reset my router multiple times a week because of connection issues, but I have not had any issues with this one. Our internet has been much faster, and I am extremely happy with this modem router. We have had several devices connected at once and all playing HD vidoes with zero lag. It was reasonably priced and I am definitely a happy customer, and I highly recommend this product!
Customer –
Awesome modem and even better customer service. Easy setup and fast WiFi. Highly recommend.
Baylen –
Easy to setup like all netgear products, the wifi speed is great if you are in the same room but back in my office I had to buy a 75ft ethernet chord because the wifi was in and out of signal – so my phone and tablet are unusable on wifi and I had to hide the chord – I might have done this anyway but I was definitely forced to.First image is within 5 feet, 2nd is within 10 feet 3rd is about 20 feet, last is 30ish feet away. It will occasionally reach a good signal but never for more than 5-10 seconds.

I bought this to save money on rental fees from the cable company. Mission accomplished. It’s fast, it’s reliable, and shiny. My Wi-Fi signal degraded just slightly but I guess that’s to be expected from something much smaller. All I had to do was put it up a little higher and problem solved. Excellent router cable modem.
Mom –
Based on all reviews I decide to buy this wifi cable modem router .. I just connected two days ago and my internet gets super super slow soI decide to check connections to make sure was proper connected and when I touch the connection I find out that was very hot And the one I have before never gets that hot so ImThinking on send it back .
julio dieguez –
I like it because it expands the WiFi and its faster
Beatrice ivory –
Was very easy to set up, when spoke with netgear tech . Everything is connected. Internet, home phone service, 4 pc Ring security Systems and Wi-fi as well as Eckerman security alarm. Love It!
J. Greene –
I installed the Orbi cable modem with 2 Orbi extenders. This eliminated all of my wifi dead zones and increased wifi system throughput by 10X. No more streaming stuttering or Sonos dropouts! Flawless!
Ron –
I had a c**##** modem that comes with my cable subscription and my download speeds were 60 to 80 mbps upload speed 6 to 8ish and the cable company said it was nothing they could do and it was because of the walls and distance in my house excuse, I told the cable company my router is only 40ft from my computer and they said their wireless router needs to be in the same room or closer or directly connected by ethernet cable in order to get the speed I was paying for. Now all has changed to 175ish mbps download and 11.3ish upload speed wow what a difference. NOW im getting what I’m paying for with Nighthawk recommended to me by my neighbor who was having the same issues with the same cable company.
Customer –
This modem/router has a clean interface – nothing cryptic or confusing – it is simple and logical. Customer Support was fantastic and put Comcast in their place! I did not have to pay the technician once they figured out it was a problem with them (Xfinity). Signal is STRONG and steady. Runs fairly cool even up in the rafters. Best I ever bought in over 24 years!
mike –
I definitely love the combo router/modem! Takes up less space and works great for my TVs and devices!
Ramona Stevenson –
I just love it! it’s fast strong! takes a lot of devices what else can I say? If your looking for a good modem this is it!
Mike44NH –
Amazing product! Insanely easy to set up and works perfectly with Xfinity and Alexa. Very strong WiFi signal, much stronger than our Xfinity router’s was. Love this product.
Javier Noriega –
This is the best Router/Modem I’ve ever owned. Great App and easy to use and understand.
C-los –
I really like the small profile and the beamforming technology.
goldieeagle –
I was able to set up the router easily with my Xfinity account. And most of my other electronics connected with few problems. Having problems with my Emerson Sensi thermostat but am trying to resolve that with Sensi, since I do believe it is their problem. Netgear support has been extremely helpful as I am working through this problem with Emerson.
Nanimirai –
Less than a year after buying this gateway modem/router and netgear will not help unless I pay a premium for support??
Digna Bonilla –
Easy to install and works how i wanted it too.

After researching routers and combination modem/routers, we decided to try the NetGear NightHawk Cable Modem WiFi Router Combo AC1900. The NightHawk replaced a modem supplied by our ISP, Spectrum, and an 8 year old Apple Time Capsule with built-in router. We’re still using the Time Capsule for backup storage. The NightHawk has been a steady performer and delivers a strong 5G signal through our home. Download speeds more than doubled and we’re able to run multiple devices and TV streaming simultaneously without any lag or stutter. Installing and setting up the NightHawk was easy and took about 5 minutes using the instructions including with the equipment. Check with your ISP, to make sure they support the NightHawk. When we informed Spectrum, I think they made a technical adjustment to our account on their end to accommodate the NightHawk. Again, great piece of equipment!
Tech1Tv –
I got this router to use with Comcast and it’s fast, when i’m downstairs the signal remain 4 bars. I wanted a better router to replace the old one i had with speed and signal, this one is good enough for now. The only thing is i wish it was smaller, the router is wider than my Xbox One S.
Cyler –
It’s huge! As big, if not bigger than my PS4 Pro! Easy to install, although my speed dropped by half compared to my old modem router. Didn’t want to call my 1 star cable company…
Keith L. –
I researched and looked at lots of different modem models and then I found the Orbi and saw that it had a satellite to help with WiFi signal got it hooked up and going love the Orbi especially the phone app to turn off WiFi to TVs when granddaughter doesn’t listen I’m able to shut tv WiFi off. Internet servicemen really liked it and I’ve told many people how good it is. Everyone should get the Orbi
James w. –
Mostly like it it’s size easy to see and not so big and bulky.
Shane –
When I got it set up, I received around 300 mbps, even tho I’m only paying for 100 mbps. The range is outstanding, and it seems reliable 100% of the time. Don’t waste your time looking at other routers, this is the one to buy if you have cable internet. The best part is, it’s nice and compact.
pete haralambopoulos –
Love this product! Highly recommend it!!! Satellites are amazing! Very happy 😊
Trinh –
Arrived damaged, someone really destroyed it
Suraj Gupta –
One of the best built-in modem router and good wifi signal as i was looking for.

Easy to install, and loves the dual band options. Gets enough coverage in my 1600sqft house. 4 stars because 2.4ghz band is not giving me enough speed during speed test.I have 7 devices running on 2.4ghz, ring door bell, 2 ring flood lights, ring chime, firestick, and 2 tablets and they all work fine. I do however notice that the firestick will lag time to time but its not bad. Just wished the 2.4ghz band would at least give me half of my internet speed (100mbps with xfinity, check the picture i have when im on 2.4ghz band, im only getting about 5mbps.)I also have 2 iphone and my pc running on the 5ghz band and they are running up to speed plus a little more with my internet plan of 100mbps. Im sure i can hook all the devices on on 5ghz since my house is only a one story but no point when im manly using my pc and iphones for the most part.Ive attached a photo of my speed with 5ghz on my iphone. The one highlighted in yellow is verizon lte and Green is running on 2.4ghz. Ive tested all 3 a couple of times and all the results were similar.
Laurie Canney –
Meets the specs for Comcast requirements for Xfinity.
Honest Mike –
What can I say? The thing should be called the “Usain Bolt” package. Went from 80/ 12 speeds to 260 / 23 speed in seconds. I would say the ONLY issue I faced in this simple installation was contacting Comcast to activate the device. Took me all of 3 hours to find the right department to know what and how to service me. Outside of that, the product is RIDICULOUSLY fast. Perfect for streaming live tv, video games, and movies. My service is 600mbps from xfinity- and this Modem/router offers me up to up to 400mbps (although Comcast said it was pushing 650mbps). All in all this is overkill but nice to have if I ever need it at a really fair price.
Customer –
Got the router and it didn’t work. Gave to my friend that has the same one to check it – no output signal.Going to return ……
Christophorus –
Easy to install almost a plug-n-play setup, follow the netgear activation instructions then optimum modem registration instructions. Done. SuckIt Optimum you ain’t getting 10$ a month from me no more no more no more hit the road jack
Dale W. Santee –
All in one modem/router was easy to set up and use. Made a huge difference in my desk top and notebook speeds without having to have Cox increase the speed. Highly recommend it.
Chris M. –
Comcast bumped our router rental fee up to $14/month so we bailed. We do ALOT of gaming and decided to spend the extra coin for this C7800 unit. We use Xfinity Gigabit and were seeing speeds around 100Mbps with the Comcast router. Took about 15 minutes to install and link up, then ran a speed test and came in just over 400Mbps download (pictured), and occasionally double digit upload speeds. We don’t have TV or phone service since we stream everything so I recently ran the coaxial coming directly from the telephone poll into this router (with proper grounding) and now pushing speeds around 600/30Mbps. Blazing fast for living out in the sticks like we do.My only concern is that my neighborhood is slowly being switched to fiber and I cannot find any info on compatibility with the C7800 unit.
Eddie –
This is the second time I try to write a review if let me finished, the signal is excellent when it works, but I hate to reset it or turn Off/On like 20 times a day if your ISP provider is Spectrum do not buy it, Netgear and Spectrum blame each other on solving my problem, I got no help at all, and I been told from both side in very polite way that is not there !@#$%^ problem, so I was done talking to this people, I will not recommend buying this unit. I hope one day both fix their issues. in the meantime, screw me $300.
Michael –
Buying this modem was the best decision I made when replacing my rental unit from comcast/xfinity. Th ed set up was fast and required NO PHONE CALL witch if you cant tell I was happy about. The range is as good as the comcast box was and I could have gone up to netgear next model if I needed more witch is nice to know, and the price feel perfectly in budget as t just under $80 I will recoup my money in less then 6 months. In conclusion I just want to thank netgear for actually makeing s product that has delivered on all promises.

Update 05/11/20 – A day after installing a Seagate 8TB external USB 3.0 drive to the C7800, it stopped being recognized on the PC via \READYSHARE. I was still able to connect to the drive using VLC on my Samsung Note 9, but I was getting an SMB1 error on WIN10 which didn’t make any sense as had been working just fine. After poking around online I found that the SMB1 protocol is out of date and using it opens you to vulnerabilities, I almost gave up and then decided to try to reset the router to its default configuration. In doing so, it upgraded my firmware from 3.01.40 to 3.01.43 and it also fixed the \READYSHARE issue – go figure.ORIGINAL COMMENTS BELOW:So far, so good. I am getting strong WIFI on 2nd floor of house with the router located in basement. The 1st floor sub-flooring in our home is concrete and steel (1930’s junior beam construction) and I had previously had issues getting any signal to 2nd floor even with WIFI extenders. My setup was painless as well as the Comcast installer called it in and had them activate it while he was onsite doing the cable install. I am connected to Comcast 100mbps service and am seeing slightly over 120mbps speeds on Speedtest via a Cat6 ethernet cable.. Roku and Tablo are flying along now. Will update as we get more time and use out of it.The 114mbps screen grab was done on my Samsung Note 9 using 5G wifi from the 2nd floor of our house. The router is in the basement and the signal has to go through steel I-beam and concrete subflooring on the 1st floor. We have Comcast 100mbps service, so it exceeds what we are paying for and the range is phenomenal. We used to need a wifi extender to get any signal bars on the 2nd floor of the house.

Apart from the usual devices (like TV, phones, laptops and iPad) if you have a smart home setup like Alexa, smart bulbs, smart switches, doorbell, cameras etc, then this is the modem / router you must buy.For a long time I had the issue of my cameras going offline almost once in every 2 days. Then I decided to return the internet service provider’s modem / router and purchased this one. Things have changed now. No more offline devices. Great internet speed over WiFi. And WiFi range is very good.
DonnieAles –
Instantly better, I went from roughly ~10Mbps to ~110Mbps in a matter of 20 minutes. Set up was easy. Highly recommended. I am on Comcast $30 a month 100Mpbs service in Chicago.

This Modem continues to drop the Internet every day rebooting it and rebooting and rebooting it call technical support they told me what to do at work for a little while now is the same thing Internet dropping Internet dropping I also have Xfinity to come out and check the box and they said the box was no good and I need it to return it but instead I called for support and it worked for a little while now every day the Internet is dropping
Quincy C. –
I upgraded my Xfinity internet to a higher speed package, so I decided to upgrade my router as well to handle it. I chose not to use a Xfinity router (I read many people recommending to not use a Comcast-provided router), and got this Netgear modem. Before I changed my router, I tested my new internet speed on my old modem, and it topped out at around 100mbps, but it jumped to 239mbps after installing this Netgear modem.Installation was easy, but I did have to call Comcast to get them to finish setting up my new connection. It surprisingly didn’t take them very long (maybe 10 minutes on the phone – I was expecting an annoyingly long wait or multiple hiccups). Anyone looking to upgrade their Xfinity Internet package should consider this modem as well.

DEAD INSECTS SQUISHED INTO ETHERNET PORTS! UNIT INFESTED! WTF?!This is absolutely DISGUSTING! Description said “Used / Like New” not “Used and filled with insects both live and dead”I’m not exactly sure what kinda NASTY home this came from but for it to even be approved as refurbished is an absolute JOKE!Bugs were crawling out of the packaging when the item was opened. Absolutely UNACCEPTABLE!

Upon doing a lot of research between other cable modem/router combos, I finally decided the Netgear Nighthawk AC1900 was the best selection to fit my needs. I live in a home that is 1850 square ft and the wireless coverage reaches in all areas of the entire house with no problem as I performed multiple speed tests and the results were very consistent throughout. The setup through the router setup management interface was seamless and very user friendly. I was able to set up my 2.4Ghz, 5 GHz, and guest wireless networks in 3 minutes. I also like the fact that you can set parental controls to manage usage time and block inappropriate websites. The Netgear ReadyShare Vault is extremely handy for me so that I can share movies, pictures, and files across the network. Overall, I would highly recommend this product!

I was looking for options before moving into a new house with a new internet provider, tired of renting dated technology with limited options and slow speeds. Researching my options I found few products that combined a cable modem with a wifi router. I looked into Netgear’s Orbi system and found many positive reviews. Purchasing the system was a challenge because they were either sold out or back ordered on most sites, something however that I took as a positive sign as they must be in demand. Moving into the our new house the first thing I did was connect the cable/internet and set up the Orbi. The set up was quick and easy and worked exactly as the app said it would, creating a home network, guest wifi, parental controls and more. Next the set up of the satellite was even easier. Once the ring turned blue we were in business. My entire home, yard, driveway, and I’m sure to my neighbors dismay is now blanketed in coverage. We are paying for 300mb speed from our provider and range from 280 to 330 on wifi tests throughout the house, and that is with 28 devices connected. The main family desktop is connected with the ethernet cable and just tested at 340mb. So to say that we are extremely excited is an understatement. On a typical day there are five people teleconferencing at once, two taking college classes, two teaching high school classes, and one conferencing with work so high speed, reliable internet was a must and Orbi delivers. The only question I have now is when should I look into the 6 system, because if the wifi works so well with this system I can’t believe how much better it could get. Yes the system was on the more expensive side and I could have pieced together a system that was cheaper, but why when this system works so well together. Tired of drop outs and dead spots I wanted and received a system that is reliable and delivers more than it promises. I would highly recommend Orbi to anyone and everyone that will listen. Some things you can not compromise on, in today’s connected world why settle for less with an internet provider that wants to keep taking your money by leasing you equipment that is antiquated, unreliable, slow and rarely updated. They aren’t the ones sitting home with you when the signal dies or reboots. You owe it to your family to get what you’re paying for, I found it in the Orbi!

This was very easy to use and the instructions was very easy to understand. However I do feel like the signal does not reach all of the rooms in my apartment very strongly so I had to move it a few times to find a good central location for it. I did call my Internet provider and give them the model number and the brand and they were able to locate it quickly and send a refresh signal and everything worked fast with this being said they were my tech-support and not the routers tech-support but everything seem to work fine.

I was excited to get this product and get faster Wi-Fi service in our house. The box claims that Spectrum has certified service for this modem. When I hooked it up I found out that is not the case after being on hold with Spectrum customer service for 30 minutes. Don’t buy this if you’re a Spectrum customer. This is getting returned.
chuck h –
Product failed (Constantly resetting) within warranty period. NETGEAR sent replacement which also failed in the same way (constantly resetting) Within 2 weeks. After four NETGEAR support cases and hours on the phone I was advised by tech support that I needed to purchase a new modem. I would strongly warn anyone against purchasing this model. And I will go as far as never purchasing a NETGEAR product again.
Valmir Mirville –
This modem/router arrived at my house with a corner of it chipped off. THOUGH WHEN PURCHASED, IT SAID THE ITEM WAS VERY GOOD. When ordering this item I decided to buy it used because the condition was “very good” and it was overall cheaper of course. DO NOT BUY THIS ITEM USED. Setting up this device was a pain because of two reasons, first of all, this item was already activated on someone else’s account and I had to spend 1-2 hours on getting It activated onto my account. Second is that though I had access to change the settings of the modem/router, it was not receiving internet from my internet provider. I was on the phone with Netgear for a long time just to get it reactivated onto my account and on the phone with my internet provider just for the modem/router not to work, this in total took me about 4 HOURS. When in the settings of the C7800, it says there is no cable connection, though it was plugged in and my internet provider said there is the internet going through. LOOK ELSEWHERE.
Customer –
Super happy with this purchase. Definitely worth every penny! The way I see it is if you rent the xfinity modem in a year you pay around 14$ a month and in 12 months you have already paid 168$ to rent some equipment. Anyways I would recommend the Netgear Nighthawk modem I got the one without voice as I only have internet service through Xfinity and let me tell you setting up was quick and easy and also my connection at home has been great not once since I have purchased have I had any issues. My husband is a gamer and I love watching YouTube or Netflix at the same time and never have had any issues.
Randy Robins –
The modem started working right away. All the cables were easy to hook up and we didn’t have to reset anything. Super easy setup. I would highly recommend it to anyone!
