[Connor Imes <connor.k.imes@xxxxxxxxx>]

Disconnected with "Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA" on this
particular network multiple times.

When I restart the wireless driver, it can sometimes try to reconnect but fails with:
[567624.534081] wlan0: aborting authentication with bc:f1:f2:90:d0:ee by local choice (Reason: 3=DEAUTH_LEAVING)

Title:
  [Lenovo Thinkpad X1 Carbon 3rd Gen] Wireless disconnects using Intel
  7265 [8086:095b] (rev 59)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Wireless disconnects from networks randomly - sometimes connections OK
  for days, other times for only a few minutes.  Sometimes a wireless
  power off/on or system standby/resume re-establishes connection, but
  usually a reboot is required.

  Wireless hardware and symptoms similar to bug 1437913, but different
  laptop model.  Log messages vary depending on the type of network
  being used.
