A friend recently asked me to look at their computer because it was running very slow. I discovered that their copy of Windows XP was corrupted , so I did a clean install. Before I did this it would connect to my Linksys Router which is set to WPA, however now it wont connect. It is giving me an error message and wont accept the passphase because it can only see WEP. How can I get WIndows XP to detect myr routers WPA setting
