For some reason, on my desktop, I have to input the wifi password to a network every single time I want to connect. If my connection drops, I have to resubmit the password. This is on a network with a WEP passcode (I'm not the one who manages the network in my house so don't ask why we haven't switched to WPA2.). On my laptop, it works as it should. What could cause Windows 7 x64 to behave this way?
