How can that take two seconds? All that would be needed here is to send
out a unicast Probe Request to the current AP and wait for a Probe
Response for a short timeout, say 20 ms. That shouldn't take more than
50 ms or so at most.. If the current implementation uses two seconds for
this, there is certainly room for improvement there and I would rather
see that done than lose this extra protection against buggy
implementations (either AP or STA for that matter).
