Same issue today, I've tried rebooting, factory reset everything, nothing has changed. Is this a tech visit that needs to happen something that needs to be done on Comcasts side?

Just noticed it can't even find my TV box, I just have one, and TV works just fine. Something really needs to be done, it's like it won't release my old modem information at all, and I can't activate any new modem either, but I can plug in my old one and it works just fine, albeit random disconnects.

Well, spoke with an agent tonight and they reprovisioned the old modem, but it still says "we can't connect to your device"

I'm at a loss here.
