Hello, I've just upgraded to Ubuntu 11.10 from 11.04. If I switch the WiFi on (using the buttons Fn + F2), it finds no network. of course my home Wireless network works, as other devices can connect to it - and the same computer could just before the upgrade.
The connection through an Ethernet cable works perfectly, though.

Oh and.. is there any way to revert back to a "classic" menu bar? I don't really like the new launcher, I feel it's confusing (but this is not very important).

Thanks for your help
