Computer connected to base not seeing laptop

I have a laptop computer with the Microsoft MN-720
wireless adapter. The MS Broadband Utility on the laptop
sees the other two computers on the network but the
computer connected to the wireless base station does not
see the laptop in its network devices list. I have
another desktop computer on the network. It sees the
base PC but not the laptop.

I have double checked the Workgroup, SSID and wireless
security key. Everything seems OK - does anyone have any
suggestions about what I am doing wrong?

How can the laptop see both of the other computers but
neither of them see the laptop?

Thanks in advance.

Check for firewalls on the computers: ICF, Norton, etc.
