Title:
  IEEE 802.11 driver crash

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Wireless connection fails out of nothing and can only be brought back
  with airplane mode on/off. Connection is stable only for like 5 mins.
  Several stacktraces in /var/log/syslog like below. Also lines line
  "ieee80211 phy0: Hardware restart was requested" or "iwlwifi
  0000:02:00.0: Firmware error during reconfiguration! Abort."

  I get a suspicion that it may be related with VirtualBox, because it
  was stable for some time until I startet a virtual machine.
