bull** use FedoraCore, but if you still want to use Suse there is a wonderful STICKY Thread that explains how to get the fullPower mp3 and stuff multi media crap support.
Did you use a qui to join them?
you can use the console to issue the command iwconfig to connect your wlan card to the wireless network.
so if you know what the key is and the correct name of the ssid and if there is no mac filter on the ap's. then for e.g.
iwconfig wlan0 essid nameofthatssid key 5B3F929A17C4C659FD081C9DB7
or as passphrase
iwconfig wlan0 essid nameofthatssid key s:daistmeinesecretpassphrase
kismet is also a nice tool to check what other don't want you to see.... ;-)
