I typically dual boot my laptop betwen a Win7 and Ubuntu partition, but keep a spare partition for playing around with new distros. Earlier this week, I decided to try out Debian Squeeze.

For the most part, the install has gone smoothly. However, the wireless is not working, and this is apparently a well known issue for Debian. The thing is, my wireless card apparently requires the iwlagn firmware iwlwifi-5000-5.ucode. I downloaded the updated 0.33 package that supposedly includes this firmware and installed it using the package manager.

It still isn't working, as dmesg | grep firmware returns 'looking for firmware v5, found v0'

This laptop is over 2 years old and I have zero problems with networking in Ubuntu Maverick. Any solutions?

There is a package in backports, have you tried that? packages.debian.org/squeeze-backports/firmware-iwlwifi – jasonwryan Sep 26 '11 at 23:22
Tried and didn't work. Wired ethernet works fine, not wireless. I can see the package contains the 5000-5.ucode firmware, but its not loading at all for some reason – Jason Sep 27 '11 at 0:41
Have you installed wireless-tools and modprobed the module? – jasonwryan Sep 27 '11 at 0:43
I have. However, I'm unsure if modprobe is working, since su modprobe iwlagn produces no output on the CL – Jason Sep 27 '11 at 1:10
Can you please update your post with details of your kernel and card? – jasonwryan Sep 27 '11 at 1:52
