i have the linksys router hooked up to 2 comps runnin xp pro. I used to be able to transfer files through the network fine. Now when i try to take a file from 1 computer to the other, it asks for a password so i enter it thinking all is going well. I press enter and nothing happens. the passwod window disapears and then it comes up in like .1 seconds asking me for password again and again! anyone know what the problem could be?
