I followed the instructions and managed to install the wifi card. I'm running wpa_supplicant with this command:
wpa_supplicant -i eth1 -c /etc/wpa_supplicant.conf -B -D wext
I can join the networks and browse the network perfectly. But, if for some reason, i need to stop wpa_supplicant, the systems hangs. I'm trying to kill the process with "killall wpa_supplicant". Any of you experienced the same?
