One way...
When a wireless NIC roams it will create a System Event 4201 and 4202 codes under the system event log of the PC. You can actually see when the NIC moves to a new AP (4201) or re-ASS to an existing one (4202).
I use this often when troubleshooting.
I am not aware of a "log" in the WISMs or WCS. But perhaps someone else might chime in..
But give the event log a spin. It will give you the exact time and datw when the wireless nic roams.
