Is there a way to see how many (and who'm) is trying to connect to my different access points ?
(there is a car with an antenna thats parking around here and it seems like its doing some kind of testing - or trying to gain access? hmm)

Log?

At most the number of people exposed to your SSID password. (how many others really doesnt matter).

I use DUDE to collect all registrations (instant view of connections) and via it's syslog, collect all wifi logging of all AP.(historic view)


If you want to see all (including failed) attempts also add "wireless" to logging. (this will include "wireless,debug" info)


. All Audi's in the town where I managed the city network, tried to connect to any SSID they saw. A bit like most iPhones. The owners have no clue this happens.
They succeed to associate if the network is open (eg with a Hotspot for login).
