Seems like the Fritzbox has been updated (or should I say downgraded) in the course of the night. Its shows version 05.51 now (Its a Fritzbox 7360)
My SO was up first and there was no internet, so she pulled the power and let it boot up again. It came up with a blank setup (so on the setup wizard).
So I got the task to set it up again, luckily Snap have the details for connecting to their DSL on their site, because just entering the username/password combo did not do the trick.
One of the changes is that there is nowhere to change the DNS (except in the config file).
Anyone else experienced this kind of situation?
