KWiFiManager, SUSE 10.1 and ThinkPad R31

I am running SUSE 10.1 on an IBM ThinkPad R31. I have been trying, without success, to use KWiFiManager to configure the built in wireless adapter. When I try to connect to a known AP, I get an error message "Aborting network switching due to invalid WEP key specification." In the configuration editor, when I click on "Activate", I get several error messages, including: SSID could not be set Operation mode could not be set Speed settings could not be set Encryption settings could not be set Power management settings coud not be set So, it appears that I cannot configure anything with KWiFiManager. Also, prior to running SUSE 10.1, I could use WLAN Assistant, but that no longer works either. any ideas? tnx jk
