The solution is for debian, but it worked for me on Kubuntu 11.04.



Hi,

I just installed Kubuntu, and my wireless is not getting detected. I tried a variety of solutions I found online, but none worked. It worked perfectly for Ubuntu Gnome.

When I tried installing the Broadcom drivers in the "Additional Drivers", I got an error that the driver could not be installed.

I ran the script in Hippytaf's sig (sorry if I got the name wrong).

I have attached it in two parts. It exceeded the maximum file size limit.

I read the output from that script, and I saw some "dell wifi" stuff that causes me to ponder a bit...

Your wireless interface looks to be a Broadcom 4312 wireless, and I seem to recall "chili555" mentioning a problem regarding the "dell-wifi" module causing problems there that somehow interfered with the Broadcom wireless, but I didn't run Linux back when I still had a Dell laptop (an old work computer, or else I would have run dual-boot Linux by choice).

Looking at his most recent posts, I only found some stuff for an Acer laptop wireless that was interfering with an Atheros wireless, but I seem to remember Chili having a quick fix for at least one Dell laptop, too. Chili's PRETTY-DURN handy when it comes to this Networking stuff!
