yast and 2 interfaces ( 9.1 )

Hi, Finally got dsl at home so obtained a wlan card to use there. Need cat5 eth0 at work ( NB laptop ). wlan at home running dhcp. Yast seems incapable ot setting the two interfaces up. It either copies static eth0 IPs to the wlan cfg file ( when specifically told not to etc etc ). Tried scpm with boot options but that also seemed unreliable. Have now resorted to editing the settings in /etc/sysconfig/network manually for the two interfaces and will try again this evening. Is there a known problem with yast regarding this? Cheers and TIA Francesco
