I am a first time user of Ubuntu. I installed 10.4 on a Dell E6400, and I cannot get the wireless to work. It tells me to enable wireless. At first turning the switch off and on did nothing. I searched the forums and found an answer to something similar suggesting to go to system\administration\hardware drivers. This seemed to find some broadcom drivers for my wireless card. I activated them and restarted the computer. now when I turn the switch on or off the led indicator on the laptop lights up or off, but the network indicator tells me the wireless card is still disabled. When I first connected to the Hardware driver program it gave me 2 choices. I choose both, thinking that the most correct one would stay. After I restarted only the one that installed shows now.
I saw some instructions on launchpad in other posts where information was requested.
