24.7.2 Multiple Network Devices
Modern laptops usually have a network card and a WLAN card. If you congured both
devices with DHCP (automatic address assignment), you may encounter problems with
the name resolution and the default gateway. This is evident from the fact that you can
ping the router but cannot surf the Internet. The Support Database features an article
on this subject at http://old-en.opensuse.org/SDB:Name_Resolution

24.7.3 Problems with Prism2 Cards
Several drivers are available for devices with Prism2 chips. The various cards work
more or less smoothly with the various drivers. With these cards, WPA is only possible
with the hostap driver. If such a card does not work properly or not at all or you want
to use WPA, read /usr/share/doc/packages/wireless-tools/README
