number of users accessing a wireless network

[Kamaraju S Kusumanchi <kamaraju@bluebottle.com>]

My current network configuration is

ISP --> wireless router ---> comp1
                        ---> comp2
                        ---> comp3

The wireless router is wrt54g. The computers might be running Debian, M$
etc., Is it possible to figure out the number of users and IP addresses of
active connections served by the router?

thanks
raju
