Was running Ubuntu 10.4 until last night when I was prompted to upgrade to 10.10.
Following the upgrade, my BCM4321 wifi card will not work. My wire'd connection and tethering my android mobile phone will allow online access.
Below is my wifi card..... I have gone to Admin > Additional Drivers and disabled/re-enabled the drivers without luck. When I click the little wireless icon where I would normally select my wireless network, it says "no network devices available."
eth1 Link encap:Ethernet HWaddr 00:1a:73:f2:71:ce

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

I would like to avoid having to do a clean install of 10.10 on this laptop as I have a ton of information saved on it and don't have the time to dedicate setting everything back up.
Edit to add:
