opensuse wlan

Hello everybody, this weekend i tried opensuse rc1 - everything looks fine but I cannot connect to the internet via my wlan. I had the same problem with 9.3 but I could solve this by deleting my ethernetcard in yast. In rc1 I cannot delete the ethernetcard. If I click on delete the card does not disappear, it simply is markedt as "unconfigured" and that doesn't help (at least on suse 9.3) - is there any way to delete the card? Excuse my clumsy English ant thanks for your help. helmut
