Arris TG862R Wireless DOCSIS 3.0 Phone Cable Modem

work’s good

Reduce your monthly Xfinity bill by buying this instead of rentling their modem. Works great.

This product stopped working after less than ten months. Arris technical support was awful and not helpful. I hoped this was an isolated incident and purchased a second modem, as I do not want to lease one from Comcast/xfinity. The second one lasted about ten months. Arris technical support is awful!!!!!! Arris would only help if the modem was registered to Comcast, and online. My problem is that modem never stays connected to Comcast, if it connects at all. My phone is through Comcast as well, so I have no other way to contact Arris technical support. Arris’ response – “Then there is nothing we can do for you”I purchased the second modem in September 2017. It worked fine for a few months, then would randomly restart. I contacted technical support when unplugging and replugging didn’t work anymore. I was told that I could only be helped when the modem was registered and connected to Comcast – which if I do, the modem won’t sync with Comcast and I will have no internet connection or phone line to call Arris! I tried explaining this to Genesis M (your account rep), but s/he was not helpful. I suggested using another computer to connect to the modem to troubleshoot and review settings – that was denied. I also asked if I could send it to Arris for diagnosis – that too was denied. This is the second Arris cable modem I’ve purchased in the past three years and has stopped working. I will NEVER purchase another Arris product again. Their product and support are terrible!

Exact modem that comcast uses but white instead of black. Only difference is you can’t use other boxes in the same house wirelessly with this modem. Otherwise it’s the same.

The setup was pretty straightforward, had to register it with Comcast, which took them 2 tries, while I was running the setup and everything worked with the exception of the MoCa networking ability, which I used with Tivo. I found this from Arris: SO far so good, only using for a few hours but I still was astonished how quickly things went, it even copied my network info from the old box!)QuestionDoes the SVG2482AC Gateway Support MoCA?AnswerNo, the MoCA (Multimedia over Coax Alliance) feature in the SVG2842AC is completely disabled. It is also not compatible with Xfinitiy MoCA networks. (Seems like Xfinity would have this in the Frequently asked questions so you don’t spend hours trying to figure it out)Tivo boxes can be used as MoCa Bridges so I set it up with the Roamio and all is well.

Pro: Download speed tested up to 450 Mbps.Con: Pricy but worth it.

Works great with Comcast internet and voice, was able to complete the upgrade from my old cable modem using the Comcast web site with no phone calls to Comcast. I’m using it just in bridge mode (route and WiFi disabled), since I already have a Google WiFi router and mesh network.

Works with Comcast internet and phone.

After Comcast came out (charged me $60 to hook it up), it has been working flawlessly. Note – you will not be able to get this working yourself. I attempted to do it via the normal channels, i.e., their Philippine tech staff. They could not activate it, and said I had to schedule an on-site tech person to activate it. The tech guy had to “call upstairs” to get special authorization to activate it. Even he was rather amazed at the hoops he had to go through in order to activate this. So, add the $60 bucks into your final cost estimates.

i got this used ,trying to save money ,but it is registered in someone else name at comcast so i still have the monthly payments i was trying to get away from,

This item was registered to a past Xfinity customer. I was not able to install it without going to comcast and proving proof of purchase. The company who referbished this item did not realize customers may have set it up withComcast, returned it, and it was not removed from the account. Like buying a locked or stolen phone. Annoying

Got this for Comcast package – internet cable and voice…works very nice…no hiccups.

Installed smoothly and works at the first try, without a need to call any company. Phone support worked as well.

This is a good product and the price isn’t bad if you really need both an Xfinity cable modem and a high capacity router. This is one of only two models that Xfinity recommends for 400 Mbps internet connections that work with Xfinity’s VOIP landline telephone service. These are the fastest cable modems that work with Xfinity’s VOIP system. And this was the less expensive option (although looking back it might have been worth spending more to get the other choice (a Netgear model) just because of the color. This is the only white device on my computer desk and it really sticks out (LOL).According to at least one of the tech support people I talked to, a lot of people don’t actually upgrade to a VOIP compatible modem. If they have a working VOIP modem they can keep using it for phone service, while transferring their internet connection to a faster, Non-VOIP cable modem. I didn’t test this, but if it’s true it means that you can get a Gbps capable DOCSIS 3.1 modem / router and instead of this unit. I don’t think I could have saved much money by doing this, but you might be able to. Clearly there are a lot more cable modems to choose from if you don’t need them to be Xfinity VOIP capable, so I would recommend you consider this before you buy.But if you do buy this unit with the intention of using it for VOIP with Xfinity, PLEASE, PLEASE, PLEASE DO NOT CALL XFINITY TECH SUPPORT TO HELP WITH THE INITIAL SETUP OF THIS DEVICE!It comes with an excellent set of Quick Start instructions that can prevent you from doing what I did, which is spend over an hour frustrating Comcast Agents and Tech support people on the phone trying to get it all set up in one step. It just isn’t set up to do that.As per the Quick Start Guide, you start the setup by connecting your coaxial cable and either an Ethernet (preferred) or wireless connection to the modem from a PC, Mac, Laptop, or similar device with web access. When you boot up the modem it automatically configures itself to go online and prepare itself for activation by Comcast. Crucially this step takes 5-10 minutes and has to be completed BEFORE you can register it for your account. Trying to start with the registration on the phone resulted in a bunch of frustration as the constant reboots ordered by Comcast messed up the software that the modem was trying to run to set itself up. Then, as per the Quick Start Guide, you can go online and use the http://www.xfinity.com/activate web site to both register the modem to your account, and set up the SSID you and password you want to use, ideally the one you already used before the upgrade. This automatically sets up the 2.4 and 5 Ghz bands to work off the same login and to switch automatically. Only after doing this do you want to mess with the VOIP settings, which has to be done by phone. The Quick Start Instructions give you a special number (1-855-652-3446) that apparently connects you to the tiny subset of Comcast techies that know how to transfer your VOIP service to this modem.I ignored these instructions and tried to let Comcast handle the installation over the phone. The result was over an our spent with various techs trying to intervene in the process before the modem was ready for the next step. I wasted everybody’s time and effort. In the end, the modem itself had to take over and fix the installation after the tech guys had succeeded in setting up the VOIP and making it impossible for me to connect to the internet. Basically the modem had to go through it’s initial setup protocol again AFTER it had been connected to my account and VOIP service. And when I finally got back online, the modem itself brought up an Arris webpage where I was prompted to complete the WiFi setup by designating a custom SSID and Password, which I SHOULD have done during the registration process had I followed the instruction.In the final analysis it’s pretty impressive that no matter how much you try to interfere with the setup process, Arris has this set up so that you will succeed under the power of it’s own software.My advice, however, is to trust the Quick Start Guide and follow the steps they suggest. Start with the automatic modem setup using a connected device, then do the Xfinity activation online, and then call the special number for the VOIP setup.Or, if you already have an Xfinity VOIP modem, you can apparently let that handle the VOIP and use this for the Ethernet and WiFi connections. I didn’t test this, but it is what I heard from Tech Support.All in all this is a very solid piece of equipment and its good to know that it will complete the install even if you do your best to mess it up. I am getting all of the performance that is advertised now that everything is connected correctly.The only reason I hesitated to give this product 5 stars is that

Overall a good modem. However, if you want the ability to set DNS to use something like OpenDNS, then pass on this modem. The software does not allow it.

May be a got a faulty piece but this thing doesn’t work. The connection is extremely choppy and drops connection. Checked with Comcast and they diagnosed as faulty unit. That is not even a couple of months old. I guess money down the drain….

This is the same modem that Xfinity/Comcast uses. It took some time to get the phone and internet to work. The new unit works faster than the one from Xfinity and will currently save you $11 per month, so this will be paid for in less than 2 yrs. I don’t see an upgrade from DOCIS 3.0 any time soon. My TV menu also runs faster. I found that some equipment runs faster on the 2.4 Ghz and some on the 5 Ghz! Before my purchase I confirmed with Xfinity that this was a supported modem!

Works great. Glad to get rid of the monthly rental fee.

I purchased this router because the Netgear that I had purchased was breaking up on the incoming phone side. The Arris is performing perfectly.I have a large one story house and the signal works great all thru my home. And no more crackling on the phone. If you need a Comcast (Xfinity) compatible router this is the one.

works great and replaces my Xfinity modem. I am supposed to get monthly rental money back from Comcast. Now, if I can only get comcast to not revert my account back to charging for the device, I will be all set. 🙁

Will avoid comcast rental fees with this

Modem does not hold a signal. Drops internet connection every 10 minutes while the modem resets itself. Do not buy this modem – you will be greatly dissappointed

This unit works well with the Comcast cable system; it has the VOIP connection so you get cable tv, wi-fi modem and wireless router plus phone service. Speed of the internet is excellent but we do get some slow service when the neighborhood gets home from work and start using their computers. I would recommend this product.

Our internet & WiFi are slower than ever with this router. We have never had issues with our service until installing this router. Do your research & don’t get stuck with lag time & slow data!

The product worked for one week and I was not able to connect to the Comcast network. I called Comcast and they could not see the modem on the network. I returned the product and purchased a Netgear Nighthawk.
