First. That's a combination cable modem / router gateway device, not just a "modem".
You can see all compatible cable modems and combo gateway devices here;

Recommend XB7, ISP provided and fully supported.
Monthly rental cost offset by reliability, consistency, etc.,
Thanks and good luck.

@user_ef47fa Here my opinion.
Just look around the forums and you'll see that there are boatloads of issues with the CC supplied gateways !!
There is always an inherent disadvantage with these. Combo gateway devices are always a compromise in both quality and performance compared to separate units. Also, only the ISP can update the firmware so you are always a prisoner of that / them. And the firmware is typically crippled by the ISP's customizing of it and they typically eliminate many valuable features.
One of the biggest issues with them is that it is far more difficult to diagnose connectivity issues when it comes to troubleshooting. You can't narrow things down by using the process of elimination by removing just the router from the path. And if either segment fails / malfunctions, you have a total failure. I think that CC made a big mistake when they changed their policy and decided to start supplying them instead of dedicated devices. The suits seem to think that this will save them money for support costs but I think that they are getting far more support calls/complaints than ever... We certainly are seeing far more complaints in forums now !
Another issue is that they have a publicly accessible 'xfinitiwifi' link on their gateways. It supposedly uses separate bandwidth from your own. You can disable it from a link on the Comcast site, but people have been posting that it keeps turning itself back on every day.
Get separate units and keep the control of your home network in your hands instead of theirs, you'll be much happier !
Just my .02....
