I am trying to replace my Xfinity cable modem with a G36 but am unable to successfully connect it to the Xfinity network. I tried the self activation using Xfinity’s app and the HFC MAC (both manually and with the QR code) which did not work and then talked with an Xfinity live agent for about 3 hours but still no luck. They say they can see the modem but when I’m on the admin app there is nothing showing in the WAN and signal screens. I factory reset the modem, power cycled, etc. multiple times with the Xfinity agent but nothing worked.
I am able to switch it back to the old Xfinity modem and it works fine. The only recourse I have with Xfinity is to have a tech come to the house which will cost $100 but that seems useless since I know the signal is good (because the Xfinity agent switched the MAC back to the old cable modem and it works fine). The problem is definitely the G36. It just flashes blue. Is there any recourse?
