Ubuntu 11.10 doesn't connect to wireless!
I've just installed Ubuntu 11.10 on my dell laptop. But the problem is that whenever I type the code "sudo iwconfig" then some lines pop up saying "lo no wireless extensions (next line) eth1 no wireless extensions (next line) lo the interface doesn't support scanning.". My network adapters are Broadcam 440x 10/100 Integrated Controller and Dell Wireless1390 WLAN Mini-Card. Any suggestion is appreciated.
The wireless connection performs properly when it comes to windows 7.
