Can I measure the signal strengths of WiFi clients from a wireless router, eg WRT54G?
It is pretty easy to measure the signal strength of available WiFi routers from a client.  I'd like to do the inverse: measure the signal strength and/or signal quality of the clients connected to a given router.

I'm anticipating that this is easier on a router with source available like the WRT54G.
