There are three things you need to check that need to be done in order.
- Verify that the devices are working
- Is authentication configured correctly?
- Check the normal network setup
If you use DHCP to provide values such as the IP, default gateway and your ISP's DNS servers, the dhcp client can't do this until after the wireless device is authenticated with your router (the Access Point).
Even if you have the correct key and setup to authenticate, the wireless device needs to be working properly to be able to authenticate.
Note: Make sure you have wireless tools and wpa_supplicant packages installed.
A quick way to check if the wireless devices are working is to run:
Code:
sudo /usr/sbin/iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.

You can also use "sudo /sbin/ifconfig" to check if the device has an IP address.
Code:
jschiwal@hpamd64:~> sudo /sbin/ifconfig

Besides checking what is working, you should provide more information on your computer. I don't have Computer Models and wireless devices mapped in my brain. You can use "lspci" and "lspci -n" to determine the wireless device (as in the controller) that your computer uses. The "lscpi -n" will determine the manufactures code which may help in a Google search or looking in an HCL.
The device you have will determine the kernel driver that is needed. Then you may need to extract the firmware for the driver from a software driver written for windows.
If that is successful, you may be able to do the rest from YaST2.
