Title:
  Wireless connection not restored when lost

Status in network-manager-applet package in Ubuntu:
  Confirmed

Bug description:
  Whenever a wireless connection is lost and the same network becomes
  available again, the connection is not restored. Even selecting the
  network again from the drop down menu does not work, it just tries to
  connect forever.  The only way out is to disable and re-enable wifi,
  and the connection is got instantly.

  Wireless card: 03:00.0 Network controller: Intel Corporation Wireless
  7265 (rev 61)
