How long does that state last? 10 seconds? More? What kernel driver
and wifi hardware are you using?
If you just turn off the AP, the card will still think it's connected
for a short period until it hasn't received a certain number of beacon
frames from the AP, and then it will drop the connection, send a
'disconnect' event to the supplicant, and the supplicant should also say
that it is disconnected and start scanning for the AP again.
This sounds like the kernel driver is perhaps not sending the disconnect
event when it looses sync with the AP after you've turned the AP off.
