I tried to upgrade the firmware of a Vigor 2960 through their interface. Everything was working fine until the reboot.
The upgrade was from 184.108.40.206 to 220.127.116.11.
It rebooted for a while and now I can't see the router page even directly connected through LAN. It doesn't do anything. I tried this update after having issues with my fiber connection, it's 300Mb/s and it just wasn't working on pppoe.
