Cannot see other computers in the network.

[jebuchanan]

Three computers:
2 desktop running Vista, wired to a 3COM 3CRWER200-75 wireless router.
1 laptop running XP Pro wireless to same router.

All 3 computers can access the Internet
The 2 wired computers can see each other.
The 2 wired computers can see the wireless laptop.
But, the laptop cannot see the 2 wired computers.

What am I not setting correctly on the laptop?
Note (laptop) WEP is not in effect, MAC filtering is, ssid broadcast disabled.

Help, Please?

I found the solution: The card's firewall. Could not configure (open port 445), but could deactivate it. (the server and the router have full firewall/security implemented.
problem resolved.

thank you.
