Configuring WIFI with Debian

July 21 2009 : posted under linux debian hardware wifi iwl3945

I’ve just installed Debian Lenny and generally am impressed with how well things are auto detected and configured - so much easier than a few years ago - and in many ways easier than a Windows install where you have to constantly find 3rd party drivers to get things working.

However getting wifi running was a bit trickier (largely because of FCC regulations  affecting licenses and default settings).

This document got me most of the way

http://wiki.debian.org/iwlwifi

Additional lines in /etc/.network/interfaces

iface wlan0 inet dhcp
  pre-up ip link set wlan0 up
  wpa-driver wext
  wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

and wpa_supplicant.conf looks like

ctrl_interface=/var/run/wpa_supplicant

network={
     ssid="mynetwork"
     psk="mypassword"
}

And it’s all working…

This old bug seems to be fixed
