The SB5101 modem is no longer listed among "Approved devices"--but IS listed as "EOL" (End of Life)--usable but not recommended, though not YET as "End of Service" (EOS), no longer compatible with Comcast systems. They state that the EOL devices "will soon become EOL", but are not specific as to when. They state that security and other standards eventually make older modems obsolete, unable to handle faster data speeds and commonly less than secure.It's suggested users move to "DOCSIS 3.0" standard for present & future compatibility with Comcast (and presumably other carriers) The SB5101 modem is no longer listed among "Approved devices"--but IS listed as "EOL" (End of Life)--usable but not recommended, though not YET as "End of Service" (EOS), no longer compatible with Comcast systems.

It's working with Comcast for me at this moment, has been for two months now. Comcast does have a new speed standard, called DOCSIS 3.0, and this router is DOCSIS 2.0. Regarding this Comcast says, "...DOCSIS 2.0 modems will still work with our speed tiers (except for Blast! and Extreme 50), but you won't experience the blistering fast speeds now available." However, "blistering fast speed" is more in the mind of the marketing department than in reality. Once you have around 5megs of download speed (Comcast provides more than that) "blistering" becomes unnoticeable. Still, if you have Blast! or Extreme 50, apparently this modem won't do the job.

Also, Comcast can recommend.Comcast has no right to deny if the model is in their supported modem list.They recommend Best Buy as they support each others business interests.Thanks

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.

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....

I purchased mine through Direct Modem. It's working on Comcast San Francisco just fine. I had no problem with activation.

Last time I checked, Comcast doesn't offer any DSL services, so no it won't work with Comcast..

Yes, the router will work with Comcast service, just come out of the comcast modem with your network cable and into the Linksys router. This is a great router and puts out a strong signal!

Yes. That is exactly what I use it for. It was easy to set up. Just call Comcast as soon as you get it. Works great.

I don't know understand your question. I used this for Comcast cable here in Maryland until my service started having problems. Not sure if it was this modem or something with Comcast signals. But I've since purchased another modem and Comcast works fine. Hope this response helps

Yes! This is Comcast's newest modem and is designed specifically to work with their service.

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.

Yes, this works with Comcast (and most US ISPs) for plans up to 38Mbps in speed. ISPs have been pushing customers to upgrade to DOCSIS 3 modems as a means of generating additional profit through sales and lease of equipment. If you're plan is 38Mbps or less in speed, this modem works just fine.

Yes it is but you have to make sure once you get it you call comcast and register it or it will not work properly. That is with any personal modem though.

It works with any package from Comcast. I have this modem and the Performance Internet Package. Works great.

Don't know if it is compatible with Comcast. It is compatible with TimeWarner.

The one that I had purchased did not work with Comcast for me. I was on the phone with them for well over an hour & the bottom line in my application it was a NO GO. It did not work & I bought another brand & it was golden. I bought this brand/model... Arris Tm722g Cable Modem Docsis 3.0However & do not believe & spent that much...

I have comcast and this modem works fine for me.....but they keep asking me to change it and purchase the newer model which can accept higher speeds. Unless you are paying for a top internet speed from your provider you don't need the upgrade to this modem. This is a DOCSIS 2.0 modem and the newer one is the DOCSIS 3.0 modem....with a higher price. I guess this item is the "older" one but it works well with many providers (I've been told) and it's definately easy to set up. I'd check out both modems and see if the upgrade is something you want or need.
