And it doesn't as long as the selected AP is the same as the currently
associated one. This should show up as follows in the debug log:

State: GROUP_HANDSHAKE -> COMPLETED
Wireless event: cmd=0x8b19 len=8
Received 4091 bytes of scan results (21 BSSes)
Scan results: 21

Already associated with the selected AP.
