Xfinity Down Same Time Every Day

[username0475]

I have a RT-AC86U on Merlin that has been bullet proof supported by backup UPS connected to Xfinity.

After our last ICE Storm where Xfinity was down for a couple of hours due to power local power outages we started noticing the Xfinity broadband goes down same time every day (~11PM).

Asking for help to troubleshoot to see if it's their end or mine.

I have never posted logs here but what do u all need to see (& redacted) to give me a hand?

The modem has logs, the router has logs. Just find which device is going off-line and go from there.

I have the AC86U logs - it has several instances of the:

"WAN_Connection: WAN was restored." between 10.55-11.11 each day -

Assuming you don't have any reboot schedulers on your router or it doesn't reboot from other causes - check the modem logs, usually in DOCSIS Event section. If you see something happening at the same time in modem logs or with LED lights - call the ISP.
