Hi,

Sometimes after power outages my Archer C80 is unable to connect to internet via PPPoE. In order to fix it I have to do a reboot.

I also tried to re-enter the pppoe credentials while bugged out to force it to reconnect, but i's not working either.

Any idea what's wrong?

Some logs below related to the PPPoE connection...
