Hi Jeff

My 2 cents as a end user : got to the same issue with a rtl chipset from 
a nano wifi N usb plug.

I found out that

The driver needed does not load automatically (distro dependant ?), 
experienced on Debian stable and LMDE
They have problems to connect to WEP (un)secured networks (reported on a 
ubuntu forum)
And eventually when I have all clear as WPA and modprobed the driver ... 
tadaaaa can't see my network !!

Still trying, will test on open suse shortly
Cheers
E
