Comcast couldn’t get it working when I called them to register the modem into their system

Comcast says the Xfinity voice is not supported with this device and that I need to

It was very easy to replace the existing device, took maybe 20 minutes for the Comcast support person to get everything set up once I put the modem in service.

We all know comcast isn't great

Works great Comcast triple play with 100gb internet.

Works great and is Comcast compatible

In the same month xfinity/comcast gets a windfall corporate tax break they raise the rental rate of their telephony modem from $10.00 to 11.00.

Final conclusion from Arris level 2 tech was faulty Comcast firmware.for which they had no fix

8 months after install and working, the phones stopped working because Comcast said the MAC address was registered to the original purchaser, and Comcast refused to connect the modem's MAC address to our account and tried to make us buy or rent a new modem.

Needless to say Comcast subsequently informed me that I cannot limit the use to to the voice modem by

The installation couldn't have been easier, Comcast was quite cooperative and helpful with registering the device and once up and running (total time with Comcast putting me on hold was about 15 minutes) the difference was instantly noticeable

So the fastest Comcast download speed it will support is 150Mbps.

I had some issues getting Comcast to register it, but after an hour of research got that figured out

Comcast had difficulty switching the units in their system and making sure the unit was connected to the correct server.

No issues at all with the modem itself, it perform beautifully now that Comcast has their information on it (serial number, etc).

Like most, I found the actual modem good, but Comcast support horrendous

The modem works with Xfinity/Comcast

I also allege that Comcast is working a con trying to get

Bought this modem for my parents but when Comcast couldn’t get it to work at their, ended up keeping it thinking I’d use it at my house

As I said previously, it took me 5 minutes to set up but it took me 45 minutes to activate because Comcast customer support line is horrendous most of the time

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.

I even found out that Comcast was doing work in my area that day to improve the speeds

Now, if I can only get comcast to not revert my account back to charging for the device, I will be all set. :-(

Comcast must have improved their systems.

Comcast said it would work for

Comcast can not get to work properly.

Comcast is not ready for this device although they listed as approved device on their website.

Also, the Comcast support team was not prepared to support this device

Yes this model works perfectly with Xfinity/Comcast triple play: telephone, TV Internet service.

The modem proved to be internet capable, but Comcast was unable to initialize the telephone port

This works if you have Comcast triple play

Comcast Xfinity 400 GB Internet and have phone and WiFi, than this unit will work fine.

he said it should work as

Works as it is supposed to.

It works as good as or better than the Comcast modem
