I have no internet at all on my Dell Inspiron 2200. I have tried everything that comes to mind.

PCI-ID: [14e4:4320 ]
Card/Model: BCM4306

I have tried following this guide:

Followed the information for: b43 - no internet access

everything seemed to be working until I go to "Additional Drivers" where i am presented with

"Downloading package indexes failed, please check your network status. Most drivers will not be available" and of course no drivers are listed.
