I just installed an Asus PCE-n13 wireless card into one of my CentOS 5.6 systems. It uses the RaLink 2680 chip set and I was able to get the driver loaded using modprobe rt2x00pci.ko. I saw no error and now see that the module is loaded along with mac80211 and other dependencies.
Now I need to know how to create the wlan0 device. I can find nothing via Google searches on how to create that device. I assumed the driver would do that upon loading, but now I expect some ioctl to the driver command may be required.
I created an ifcfg-wlan0 file, but of course ifup wlan0 always returns device not found.
Can somebody tell me where to start on getting the wlan0 device created?
What is the output of iwconfig?

Also, in the syslog I see this when I run modprobe rt2x00pci.ko:

Now I am thinking that perhaps the driver doesn't see the new hardware. I'll try it with the adapter removed.
