I managed to get it to work with this advice here
So I tried doing this with Ubuntu 8.04 a few days ago, and 8.10 a few hours ago, but anyways, here it goes:
I have a Dell Latitude C840 with a Broadcom 4309 wireless chipset on it. I just can't get the damn thing to work. The wireless instantly, out-of-the-box, works with a few laptops I've set up before, but it doesn't work with this laptop. I tried following some steps I found on the web to get the Windows drivers and use an application that will adapt it to Ubuntu, but I still can't make it work. Anyone got any ideas?
I'd appreciate any help, no matter how minor, because I am completely stumped.
