Dell inspiron 1525. no wifi connections. 11.10

the output of all commands suggest in https://help.ubuntu.com/community/WirelessTroubleshootingProcedure (aside from the two commands "sudo apt-get update; sudo apt-get install hwinfo grep")

I have installed the additional drivers that were found for this computer, which was the broadcom sta wireless driver. The connection icon in the status bar, however, still doesn't show any wireless networks.

what has happened? :(
