Well, yes. I'm running out of options.After the open source drivers/solutions did not get the Wi-Fi working, I was forced to try proprietary drivers.
By now I have attempted to apply all (!) of the different solutions documented here: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
None worked. But in Ubuntu 12.04 they worked out of the box. So there must be something else missing, I guess.
