Hi there, I typically keep my Airport Extreme broadcasting at WPA2 but my new roommate has an old PC laptop with a USB wireless adapter and is trying to log onto the network. He was unable to log onto the WPA2 network so I tried to change it to WEP just to see if that would work but it did not. In fact, I don't think the base station is actually broadcasting in WEP at all (I have a widget call Air Traffic Control that scans networks and lists their security type and my network still comes up as WPA no matter what). As well, the base station is acting a little wonky - won't show up in the scan after reset etc. I did a hard reset to restore it to factor settings and still shows up as WPA in Air Traffic Control after I recreate the network as WEP from the beginning. Anyone have any ideas? Anyone know of any other way for me to tell for sure what it is broadcasting as? Thanks, Steven.
