OK, I checked the code, and you're right - on Windows, the "interface list" dialog fetches a bunch of statistics from 
NDIS and displays them; this includes the data rate and RSSI on 802.11 interfaces.  That, unlike useful capturing, 
doesn't require NDIS 6.

In theory, similar stuff could probably be done on at least some UN*X platforms; that sounds like a job for Another 
libpcap/WinPcap API.
