Computers can't see each other

[wolverine1190]

My stepbrothers and I have been playing some games over our LAN lately. Two of us (including myself) are connected from laptops wirelessly, and the other is connected on a wired desktop. The game we had been playing is Call of Duty, patch version 1.5. All we had been doing before was one of us would create a server, and it would show up in the LAN list for the other two of us. No set up needed, just installed and played. However, this evening we went to play again and no servers show up for the LAN. It doesn't matter who makes the server, no one else can see it. If I try to ping any other computer on the network, I get no response. If I go to the network devices, nothing shows up. However, if I go into my router I can see all devices, wired and wireless. They just won't show up under the Windows network devices. I am running Windows 7, and the other laptop and desktop are running XP. We have made no changes to any of the systems. LAN servers just stopped showing up. Any help would be appreciated. Thanks

Reset your router, switch and/or access point (unplug count to 20 and plug back in).
See if that helps.
