DHCP - WLAN Problem

Hi...
on my system (SuSE 10.3 64Bit 2.6.22.17-0.1-default) I will use a
WLAN-USB Stick (Device 008: ID 0bda:8187 Realtek Semiconductor Corp.).
I have installed the actual RTL8187 driver provided by YAST and so far
all dings seems ok.
When I plug the dongel dmesg notifies:
[...]

ehci_hcd and address 9

so far, so good but when I choose the device by the network manager I get:
[...]
