Title:
IEEE 802.11 driver crash
Status in “linux” package in Ubuntu:
Incomplete
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.
