I have a network composed of an Airport extreme which is connected to my adsl2 modem, to help boost the range and stream iTunes I also added a year or two ago 2 airport expresses. To improve my security I recently changed from WEP to WPA. Both my macs find the WPA network fine registering all 3 airports, my Windows work PC finds the new network fine but my girl friend's Toshiba that worked fine under WEP can't see my new WPA network. It picks up all of my neighbours WPA networks fine but my airport network doesn't even show up in the list of available networks. At home she has a WPA network and it works fine there, what could be the problem, I didn't choose WPA2? Anyone any ideas?
