I am not able to connect to Wifi using Ubuntu 10.04, but on the same machine I am able to connect to it using Windows Vista.
I had posted this question about it earlier, but none of the solutions work.
I have the Ubuntu 10.04 LTS CD with me, how can I get Wifi to work?
have you tried this post it all about broadcom 43xx wifi card install , problem solution, etc
have to tried finding additional drivers?
system-> administration->additional drivers.
you will have to connect to the internet by Ethernet to download the packages for the upgrade to make the driver work.
