Reloading iwl3945 module doesn't help for me.

Geek87,

did wireless work for you using 2.6.24-19-generic (in Hardy) ?

Wireless was working fine on my computer until 2.6.24-19-generic, after this
(in both Hardy and Intrepid) it has been completely broken. It does however
work fine with an Zydas USB device.

Davidiam,

can you please check if you have the same iwl hardware as me ?
