Pro/wireless 2200bg Intel And Opensuse 10.3

Hello. I am new to Linux.
Installed 10.3 with YaST from "openSUSE Linux Unleasehd" DVD companion. Smooth install with all updates. Everything worked as described in the book (great for someone starting with Linux!!) Recogized my PRO/Wireless 2200BG card and also "sees" my wireless network in operation mode. (it also sees other networks from houses around)
Problem: Thought during the installation process YaST asked me name of the network and the passphrase, when in operation mode, it keeps asking the passphrase over and over again. It does not connect.
No problem at all with the wired network connection.
Maybe there is little info in this msg. for any of you guys that know 10.3. Please give me some guidelines where to start. I want to learn Linux and any help will be appreciated.
Luiggi.
