I have a home network with 4 computers on it. 3 computers are hard wired to a router and the fourth (laptop) is wireless. all use the same router.
Computer A can not see any of the other computers. It can use a shared printer on another computer.
Computers B, C, and D all are working fine, and they see the shared files on Computer A, and the can use the printer connected to computer A.
Why is Computer A not seeing the other computer's files?
