Depending on your kernel
Check your kernel
debian@debian:~$ uname -a
Linux debian 3.2.0-3-686-pae #1 SMP Mon Jul 23 03:50:34 UTC 2012 i686 GNU/Linux
Choose the correct firmware for your kernel from the site. download it and as root Copy the correct firmware to /lib/firmware
enter root password
cp carl9170-1.fw /lib/firmware/
shutdown -r now
under preferences "wireless interface" I put "wlan0"
check box to use encryption if you router is locked
on mine I had to choose wep/shared restricted and enter my key. This was weird as on my netbook I used wep 9hex[0-9/A-F]) ynmv
enter your wep key ?????????
restart wicd - done
