I recently purchased an ASUS WL530g (very small travel 4-port wireless router), but for some reason I can't seem to connect when I use WPA. OS X says there was an error connecting, but the signal bar in the menu shows full signal, although I don't seem to be able to get an IP. Problem is, back at home (overseas at the moment), I could connect fine to my DWL614 (I think) with WPA. I can connect fine with no encryption. Any ideas?
