Modem rebooting

No power loss. Modem reboots itself. Once booted, internet works fine for about 5 min. Then another reboot. Possibly too much power coming from the coax to the house?

Okay thanks for the clarification! Since you're not using an Xfinity modem, and the issue repeated itself with two modems of the same build, there could for sure be something going on within the outlet itself. Do you by chance have any other outlets in the home you can try setting your modem up with?

So here's the crazy part. A technician came out today to check it out. He disconnected a splitter on the roof and reconnected it after testing. I guess the splitter was used to degrade signal strength on purpose. This afternoon was the first afternoon in 3 weeks that the issue didn't occur

The crazy part being, the only adjustment made was removing splitter and reconnecting. Indicating that maybe something so minor as retightening that connection has resolved it?

That is definitely odd. So as of now, you are having no service issues? We can continue to monitor the issue, I would just need to get some account information, so we can track it.
