Topic: Wireless Not Working

Hey guys, n00b here.

I just made a persistent install on a USB drive of #!. Everything works great on my Compaq laptop, but the wireless doesn't work on my Dell Latitude 2120. I believe the wireless card is "Dell Wireless WLAN 1501 Half Mini-Card (4313bgn)"...

I've been searching for a while, and I found a topic on using b43-fwcutter, but that didn't work. (it didn't say the card was supported in the first place)

Thanks in advance. big_smile

Re: Wireless Not Working

Pyrobyte,
Did you get this working?
I have a Latitude 2120 too, and am having the same problems with the wireless. 

I've followed (somewhat blindly) the instructions for squeeze, but when I attempt to "modprobe wl", it throws an error: "FATAL: Module wl not found."

Could this be because it's an Atom processor?
Anyone have ideas?

Thanks

Re: Wireless Not Working

Try the instructions from this wiki page: http://wiki.debian.org/brcm80211
I guess installing firmware-brcm80211 will be sufficient to get wireless working.
Note that brcm80211 is replaced by brcmsmac as of 2.6.39 kernels.

If it does not work, post output of above commands again after trying to connect via wireless.

Re: Wireless Not Working

Thanks Xaos,
That did it (after a reboot)!
Now I'll be able to ditch dell's Ubuntu 10.10 after all!
