My windows 7 pc won't detect my xp computer unless it is wired to the router instead of operating on a wireless connection. I can connect to a vista pc fine but not the xp one. Also, the vista pc can connect fine to both computers and it's on a wireless connection. The xp computer is on a wired connection to the router.
How can I fix it so I can detect all computers on the network without having to switch from a wireless connection to a wired one?
