Recently I was asked by a friend to assist him in networking his three computers. One desktop is wired to the router while two laptops are using wireless connections. XP home on all three. I shared everything as usual, including the printers and certain folders on each machine. Problem: The wired desktop cannot see either of the laptops, one laptop can see the desktop and printers, and the other laptop can see neither of the other two machines at all. Is there somethig in the wifi that needs to be opened? I am not familiar with wireless at all, but I did assist another buddy a few years ago with roughly the same setupthat worked fine. Any ideas?
