I purchased the Arris model SVG2482AC as it is listed in the above reference as one of the approved modems. I called Comcast and requested help to get it connected, I was informed this modem is not compatible with the xfinity and that I needed to return it to get a refund. Why do you have it on your list if it is not compatible?
Either Comcast lied to you or you may be in an area that is slower to certify devices for your local network. If you look at the product box in the link below, it states that the SVG2482AC is approved for XFINITY service. In fact, Comcast is the only ISP that has approved this modem/router/voice device.

The ARRIS SVG2482AC is an approved modem for Comcast XFINITY service. You may want to call again to speak with someone else to try and activate your device. Sorry that Comcast put you through this inconvenience.
Do you know if any new DOCSIS 3.1 modems are expected to hit the retail market any time soon? I’m interested in upgrading to DOCSIS 3.1 (especially since Comcast nearly bricked my DOCSIS 3.0 in April via some “upgrade” to gig, which required us to spend an hour with tech support to partially fix the problems it caused), but if a new gen of 3.1 modems is likely to be released soon, I’d rather wait. Thanks.
Sorry, no news on any new next-gen DOCSIS 3.1 modems. Current-gen DOCSIS 3.1 modems are still relatively new (many ISPSs haven’t even upgraded to gigabit speeds yet).
Keep in mind, most people don’t have access to gigabit speeds (expect that to take a few years to achieve). That really needs to happen first before several generations of DOCSIS 3.1 modems pile up.
Officially supported DOCSIS 3.1 modems for Comcast XFINITY today are:
ARRIS SB8200
Motorola MB8600
NETGEAR C7800
NETGEAR CM1000
Using one of these Gateways. Will I still be able use the Xfinity (public) wifi hotspot? I sometimes use the hotspot instead of my home network.
Yes, Greg, Comcast will allow you access to the public WiFi hotspots if you are an Xfinity Mobile customer or subscribe to Performance Internet or above. Click the link for more info on Xfinity WiFi Home Hotspots FAQs.
You people are either stupid or just flat lying to me and others. You keep telling me my ARRIS svg2482ac 1750G, is not compatible with your system ! Well answer me this ! Why does it have it listed here on ‘your’ list of approved/compatible modem/routers ? I need a good, complete explanation as to why you say it won’t work, why you have it listed as, does so I may inquire with the FCC. I am tired of all this run around. I bought the modem you told me to about a year ago, it’s been working till a few weeks ago, but, now, shows, “wifi not connected” ! Waiting for ASAP response !
Sorry, Kenneth, you might be confused. ApprovedModemList.com is a site that lists compatible modems for each ISP. This site is not Comcast. If Comcast told you to buy the ARRIS SVG2482AC, that was a big no no. The SVG2482AC contains an Intel Puma chipset which can cause connectivity issues. You can read more about Intel Puma 6 Modem List Chipset Defects at this link.
You should contact Comcast directly or visit a local service center to hopefully help resolve your issue. At least you got about one year of service out of the device, but Comcast will probably tell you to purchase another modem. In the future, try to only buy non-Intel Puma chipset devices (avoid modems listed on ApprovedModemList.com with a black diamond ♦ next to the modem model number – do not buy).
Hello,
I love the list, but could you either add change the “X” or “check” to “No” or “Yes” or add sorting features? And add the chipset and DOCSIS 3.1 as extra columns. I am looking at various solutions for me.
Thanks
Mike
Sorry, Mike, more than half the visitors to this website are on mobile. Adding more and wider columns would make it difficult to read the tables on such small screens. The * symbol indicates DOCSIS 3.1 next to the modem model #. ♦ indicates an Intel Puma chipset. Everything has to be condensed to fit small screens.
Sorting could be a feature added in the future if it can be done without hurting page load times and search engine readability. Thanks for the feedback, Mike.
