Blurg.

So I upgraded too (to the 300mbs + phone @ $90/month). Saved me $30/month.

Since my Comcast modem I've been renting from them wasn't capable of higher speeds I decided now was a good time to by my own modem and ditch the rental.

I checked Xfinity for modems they approved and got a Netgear Nighthawk multi-gig speed cable modem for Xfinity with voice, DOCSIS 3.1 model #CM1150V. Figured I'd get something that would be good into the future.

I did the self install today, via their website, and it said "something didn't work, give us a call".

I've logged into the modem and it's connections are active and good. The voice works fine.

I called Comcast and after 30 mins on the phone confirming the MAC and Serial over and over, the guy tells me he can't add it. (Eventhough it's actually showing as my device on my xifinity account online). He said I should send it back and get a different one. What? It's approved by Xfinity, it's advertised for use with Xifinity, it's connection is functioning (per the lights on the front, per the log in the modem admin, per the fact I could access the activation webpage and as evidenced by the fact the phone works). But, nope, it's the modem's fault apparently.

Anyone have any tips for navigating Xfinity's tech support or keywords I need to use with those guys to get them to add the modem to my account properly?
