this opensuse forum post might help
usb wireless is known to be , for the most part, a pain to get running
also on the KDE4 desktop there is a "network" widget
in the bottom toolbar "r-click" it and select " add widget "
in the search box type" network"
then add "Network manager" to the desktop or toolbar
open it and put a check in the "Enabling network"
unless opensuse is installed on a laptop ( and even sometimes then)
networking is turned off by default
in the user interface on the desktop there is a "pop out" tool bar
the "adjustable wrench " icon is the configure tools
from there you can configure the network
