T3 Timeouts, Random Modem Restarts, Random slowdowns, 1.5 years without a resolution
Can anyone advise me on how to get this in front of the right person at Comcast? New lines, tried the Comcast modem, switched back to my own modem after problems persisted. Neighbors have the same issue. I also noticed that despite me having a generator, Comcast drops immediately on a power outage indicating that the backup battery in the node is also dead... I used to get 10ish hours after a power outage of usable internet, but not so the past year. Instant down. How do I get this to the right person at Comcast to resolve these area issues? It really feels like we've been forgotten about. I've had AT LEAST 8 interactions with support in the past week on chat, phone, and even twitter. I am not getting anywhere with this. I finally was able to get a tech scheduled tonight, but I am not holding out any hope as the issue isn't isolated to my home.
