Re: Periodic Disconnect: Need reboot to regain connectivity

I have this same modem and have the same issue with weekly/periodic reboots to regain connectivity.

 

How are you getting access to the logs?  I will pulll and compare with yours.

Re: Periodic Disconnect: Need reboot to regain connectivity

How do you get to the log?

 

When you access the modem management page, typically https://192.168.100.1/cgi-bin/status_cgi

 

You need to click onto "event log" in the top menu bar.
