Hey i have a problem after updating to 11.2 (KDE).
Since i updated my WUSB54g Wireless-Lan Adapter it won´t connect to my router (Fritz!Box 3270).
After a while i switched to KDENetworkManager but still no internet connection nor access to the router. It says “Activating…” after pressing “connect”. In Suse 11.1 everything works great out of the box.
Need help!

Go to the wireless forum and read the stickies. Does the rt2500usb need external
firmware? You can check that with ‘dmesg | grep firmware’.
As far as I can tell, rt73usb is just plain broken in this and other 2.6.31 distros, so all rt25… chips are dysfunctional. See [xubuntu] rt2500 chipset wireless not working with 2.6.31 kernel - Ubuntu Forums](http://ubuntuforums.org/showthread.php?t=1304759) . Together with broken autoconnect (WLAN/cable-combo) in Networkmanager, see various threads in the wireless forum, this creates an “extended WLAN-fun edition” 
My current workaround looks as follows.
Make sure all network connections are NOT set to connect automatically in Networkmanager.
reboot
go into a root shell and enter:
iwconfig wlan0 power off
iwconfig wlan0 txpower auto
disable+enable wireless in NetworkManager.
Connect manually using NetworkManager.
If necessary, reboot and continue with 3.
I have tried to enter the iwconfig commands into /etc/rc.d/boot.local but this only managed to completely disable wlan0 (“there is no such thing as wlan0”). Maybe /etc/rc.d/after.local will work better or maybe I’ll just wait, till smart SUSE people fix this by update
Edit: This fixes WLAN for my “Micro Star International RT2573” internal notebook USB device.
Both didn´t worked for me:-( But when i use iwconfig it displays my wireless network but i can´t connect to this In googled the problem so often and i cant find a solution.

Does ‘sudo /usr/sbin/iwlist scan’ show your AP?
What does ‘dmesg | grep rt2’ show?
Hey, thanks for the support
