# This test run is designed to check that the connection manager
# re-scans a few times before quiescing after losing a connection.
# We simulate this by shutting off an AP in full sight of the
# DUT, waiting for a bit, and then re-instating the AP.  We choose
# a hidden AP since this requires the connection manager to do the
# scans (since only the connection manager knows to scan for them,
# as opposed to wpa_supplicant).
