Dsawhney, thanks for the info. This solution didn't solve the problem though. It erased my internet settings after rebooting (as described in the post you mentioned), and I couldn't connect to the internet at all, not via browser, not via other apps.
Luckily I made a backup a few days ago. I restored that backup and now I'm back at where I originally was, the first post of this thread.

Any other solutions?
