I just bought an asus wl-167g wireless adaptor (uses rt2570 chipset) for my 12" ibook running ubuntu breezy badger and I can't make it work. I origonaly thought it used the rt2500 chipset, but it was in fact the rt2500usb which is different, and aparently the rt2570 is the correct module to use. In any case, it dosnt' work, heres the situation:
