AP management tools should be able to tell you which AP a client is connected to but I do not think there are any AP management platforms that can triangulate on clients (yet). Finding the AP for a client is also possible via the syslogs (we also have a web interface to a syslog so we can easily track IPs and MACs to APs.)
Cisco's WLSE can triangulate on rogue APs with some success. I assume that Cisco might be able to add client triangulation via RF (we have been asking for triangulation on non-AP interference). But this is the type of feature that only makes it in if there are enough customer requesting it. So all you Cisco sites... please call your SE and AM :-)
Without some form of triangulation (over time), manually finding a client once you have the AP is very difficult. RF bounces and it can be difficult to pinpoint any source especially if it's not chatty.
We started some testing with a portable spectrum analyser but that only works for general RF, not from a specific client (at least not right now). Our short term plan is to test Airmagnet handheld sw on iPaqs with directional antennas, we just have to find a combination that works and is highly portable (directional antennas don't seem to be compact).
If anyone has a good solution, let us know.

looking for recommendations...
We just spent a couple of hours trying to locate a machine misconfigured for interface bridging. The wireless interface was the bad boy, and all the address we had. I walked around a while with Netstumbler, but only found my access points, not the client I was looking for.
Does anyone know of a device or software package (perhaps for the iPaq) that shows reliable signal strength and preferably MAC address at a minimum for �LL 802.11 devices in the vicinity?
