are this modem compatible with comcast or not ?

yes. I have comcast and it worked perfectly. It was the same model I was renting from comcast before I got this one to replace it. Hope this helps....

Yes it is. I have Comcast. Comcast has a list of compatible modems on its site.

They both support docsis 3.0 so I don't think there are any kind of differences between the two.In fact the modem was exactly the same as the one Comcast were providing last year and I had to give them the serial number so that they know this is not a rental.

I've had no issues with it. The tech when he installed my service tried to upsell me a newer modem saying this one was too slow. I constantly get 8 Mbps down and 5 up. And yes I have Comcast.

NO, this is not compatible with Comcast. This is a DSL modem which uses a standard phone jack (RJ-11). Comcast is a cable provider and uses a different type input.

Not true. Comcast installed mine. It was a replacement for one of theirs. I ordered the exact modem that Comcast had sipplied.

No it's not. This was a model sold wholesale to Time Warner Cable and while it might sorta work on Comcast, it's not compatible with their "Blast!" service so you'd top out at able 6 MbsI got this a few weeks ago to use with Comcast and it was a disaster. Ended up with a Netgear N600 instead.

I've had this modem for a long time and I have Comcast/Xfinity. However, I just looked at the approved device list on the Comcast website (http://mydeviceinfo.comcast.net/) and the SB5120 is no longer listed.

Will not support Comcast, has 5 portals. I am very pleased with this modem... rd

I use it with Comcast and have no issues, I can't speak to its compatibility with a wireless modem.

I'm not sure. In my area Comcast uses cable to provide internet service and this modem is for ADSL, not cable. Here's a link to the user manual: http://www.tp-link.com/Resources/document/TD-W8960N_V3_User_Guide.pdf

The modem definitely supports 25Mbps Internet plans, because it is rated up to 38Mbps. You should contact Comcast to verify. It IS listed on their supported modem page as Certified.

No, from what I have been told Comcast's voltage is too low. The one I bought would not work.

This modem indeed supports telephony. I unpacked my Amazon package, plugged in my home phone to the back, plugged in the coaxial cable, called Comcast to provision the new modem and was up and running in under 20 minutes. Here is a list of Comcast DOCSIS compatible modems: http://mydeviceinfo.comcast.net/ I purchased this one used at a significant discount and it's operating perfectly. Good luck!

my cox internet and my phone work great with this modem but if you are in doubt I would call comcast to see if there would be any conflict with their connection.

From where I was at, it didn't work for me. You should go on the Comcast website and take a look at the router compatibilities. Be careful out there because they don't work in some areas. Good luck!

That is not true. I live in Fremont and able to get the Arris Tm722g cable modem to work with Comcast Xfinity service provider.

Not sure about Comcast. I use mine with Time Warner Cable internet and have had no problems.
