Same problem for me, I just upgraded from Xubuntu edgy to feisty (kernel 2.6.20-12), and I can't connect to any AP with an Asus WG167g WiFi card (rt2500 chipset). I also have now two devices with iwconfig : rausb0 and wmaster0...
Everything still works fine with the 2.6.17-10 kernel (I don't have any other kernel version between 2.6.17-10 and 2.6.20-12) -- kernel 2.6.12-10-386 breaks rt2500 https://launchpad.net/bugs/39818 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
