Most LANs use a switch that machines and access points attach to and 
then get sent to the gateway machine/device. The switch is where port 
activity can be readily monitored. Even the cheap "web" based switches 
usually provide some port stats. If you don't have a switch you can get 
stats from, you'll have to tell us more about how your network is setup 
and maybe someone can come up with a suggestion.

In a perfect world (I don't know if this is possible) I would have a list or map of all the connections on my LAN with the machine identifiers and some sort of numeric or chart info that would be more or less easy to find at a glance.
