Can you confirm that you have:
A wireless usb adaptor rausb 192.168.1.91
A router 192.168.1.1
A wireless access point (IP not mentioned by you)
Also do you have an ethernet wired network adaptor. If so does this access the internet? If it does it rules out some firewall problems.
The fact that you can ping 192.168.1.91 shows that tcp/ip is set up properly. The result of the route -n looks OK
What about about the output from iwconfig and ipconfig?
If these look OK you need to check the wifi sttings, encryption and firewall. I would disconntect the router from the internet and turn off encryption and the firewall.
I would also look for a tool to configure the wireless settings. ESSID, key type, WEP, channels etc. You can do all this with the iwconfig command but it is hard work if you are not happy using the command line.
This link should help a lot http://wiki.suselinuxsupport.de/wikk...ConfigWifiCard
. I have never used Suse and do not know much about KDE so I cannot help much with the gui stuff. If you still cannot get the network going you might get better help in the Suse or the wireless networking forums (but not both).
