http://mydeviceinfo.comcast.net/ check here and see if it's listed. Note that if you have or want "voice" you'll have to get a different modem--one with phone plugs.

Arris modem is working, since day one, well with my comcast connection. Installed with ese, and continues to work flwlessly

Yes it should but make sure that you check with them....they now combine internet and phone I think....mine works great.

I am using this modem since last August. It is working very well with comcast (xfinity) internet service.

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

cannot answer question. I called comcast to get spec. for my router/modem, and the one I purchased would not work. can only suggest that you check with several sources to see what the spec. is for carrier.

I purchased this product because Time-Warner, my cable and Internet provider recommended it. I do not know if it is compatible with Comcast but you should be able to go onto their web site to find out. Yes, it is both a modem and router and was easy to install and has worked beautifully for me, a non-tekkie.

There is a very long review, dated October 18th, 2012 that explains it all. Try the auto install first. In my case it found a modem, but the wrong one. Look very carefully. If this is the wrong one, don't go any farther. Just call Xfinity and they will walk you through it. Make sure to tell them you want to port your number to the new modem. Although it was a process, it was worth it. Also make sure to call xfinity again after you have returned the modem to a service center. They have to be told to take the $7.00 monthly lease charge off your bill. I'm assuming you have comcast/xfinity.

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.

As a DOCSIS 2.0 modem it will work with Comcast, but if you paid for speeds above 25Mbps you should go for a modem that supports DOCSIS 3.0 as this modem will only go up to about 25-30.

You should be able to go on Comcast's website and imput what type of internet package you have and they list all the modems that are compatible....that's how I came across this modem....there's many choices ..

You need a modem and router. This works with comcast. Get a modem off this list of theirs that is d3 and IPv6 on the chart to the right. Then you need a router like this one. http://mydeviceinfo.comcast.net

for me, i just had to connect it to my cable like it was connected. Xfinity website loads and it will automatically read the info off the modem, register it, and even update the firmware for comcast. its done automatically, takes about 10 minutes, and i did NOT have to call them!

I wouldn't think so. This is a DSL Gateway/Modem (signal comes from phone line) Comcast would require a Cable Gateway/Modem (self explanatory)

I have used this with both a comcast wifi modem and a standard wifi b/g/n 300 mbps

DOCSIS 3.0 is rating for a modem. The WD My Net N600 HD is a router, not a modem. Yes it will work with a Comcast modem.

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

It will with no problems. You don't need a new modem. I have Comcast's older modem with of course a router and it works perfectly. Comcast sounds like they are trying to make you pay more money for a newer modem which is not necessary.

I have a Motorola, XBOX, and a DVD player hooked up to one. I assume comcast will work fine.

I don't know anything about Comcast. Time Warner Cable approves of this modem and it works fine with their service.
