Hi,
After follwoing the steps provided here ieee80211.sourceforge.net my network card is NOT able to get connect with wifi Access point and get DHCP address.
dmesg output:
[ 960.540000] ieee80211_crypt: registered algorithm 'WEP'
[ 960.608000] ADDRCONF(NETDEV_UP): eth1: link is not ready

I'm guessing by your kernel version you're on Debian Etch. Just to note, Etch reached end of life on Feb 15th, 2010, so you might consider upgrading.

You should not have needed to install ieee80211 from source like that. Debian provides drivers for this card. For Etch, the drive is the (now deprecated) ipw3945. For Lenny and beyond, it's the iwl3945.

What is needed, that Debian does not distribute out of the box, is firmware. For Etch, it's in the non-free section and the package is firmware-ipw3945
