Title:
Sporadically no wireless connection after resume from STR with Intel
7265D
Status in linux package in Ubuntu:
Confirmed
Bug description:
Sporadically after resume from suspend to RAM there is no wifi
connection. There are no errors in kernel log, just no connection:
[101937.000998] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[101937.003094] iwlwifi 0000:02:00.0: L1 Disabled - LTR Enabled
[101937.003257] iwlwifi 0000:02:00.0: L1 Disabled - LTR Enabled
[101937.067718] iwlwifi 0000:02:00.0: L1 Disabled - LTR Enabled
[101937.067879] iwlwifi 0000:02:00.0: L1 Disabled - LTR Enabled
[101937.082365] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[101937.189536] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
Reloading iwlwifi + iwlmvm modules clears it and connection is
established immediately.
Several times connection also dropped during normal activity; not sure
whether this is related.
