Works Find for My Internet Needs

I was appreciative that Netgear sent me an email letting me know it was time to update my router with a link to ensure I was getting the correct one that worked with Xfinity. Setup was easy and it's working fine. Internet connection is good. No issues so far.

Seamless transition

Well, the old one was working just fine and now so is the new one. Being on a fixed income I'm not a fan of forced upgrades that aren't in my budget but that's not Netgear's fault. Just a sign of the times.

Game Changer!

I've been a long time user of multiple networking devices by Netgear, most recently the Nighthawk AC1900 Modem/Router Combo with Wi Fi 5 capability. Although, I now have dedicated devices for Wi Fi 6, the CM1200 Modem has been a game changer with my Xfinity internet service.
