Enable airplane mode, after airplane mode icon shows, diable airplane mode. * Expected Result Wifi can be turned on and connected to AP. * Actual Result Sometimes Wifi will be disabled. * Occurrence rate tried 10 times, 4/10 wifi will be disabled.
Vincent, I wonder if the root cause of this bug is same as the one of previous bugs.
When there is only SIM2 in device, I cannot reproduce the bug. (SIM 1 has bug 945159 preventing me from verification)
Logs of wpa_supplicant are identical between fail and success case, except for one line: D/WifiHW ( 106): 'DRIVER SCAN-ACTIVE' command timed out. This line only shows in fail log, after wpa_supplicant sends I/wpa_supplicant( 2373): wlan0: CTRL-EVENT-TERMINATING ,and follows a longer start time for wpa_supplicant(fail case: >30 seconds, success case: <20 seconds, maybe the wifi is enabled manually in fail case?) But I can't make any judgment based on the logs.
Change component to Gaia that I might not select correct component in the begining. Wifi is not enabled in this bug, not failed to connect to AP.
Component: Wifi → Gaia::Settings
Based on log, we suspect that Gaia might receive wifi-disabled event later than normal, or no event at all, due to the timeout issue in comment 7. In such case, the wifi state in settings will still be enable, and the next "airplane mode disable" won't enable the wifi again. Please help to verify Gaia do receive the wifi disable event after airplane mode is enabled.
Triage: user confusion. (In reply to Chuck Lee [:chucklee] from comment #6) > Please help to verify Gaia do receive the wifi disable event after airplane > mode is enabled. EJ, could you work with Chunk to diagnose the root cause? Thanks.

Hi Enpei, I tried several times on latest Gaia and can't reproduce this problem. Are you using quick settings (the panel you pull down from the top of screen) to disable airplane mode or from settings app ? or if you have time, can you use your fugu show me how you make this problem happen ? thanks :)

Log with today's build will be attached. Gaia fbb6ce88ce8b7bd4d2efdb7a4a9f5a3c145f3eab Gecko a0bb585098cc89c454fac0297b5ef748d5cab82c BuildID 20131210063021 Version 28.0a1
I am currently rewriting Airplane mode to make sure it work as what we expected and after some testing on my drafts, it seems that this problem doesn't happen anymore. I think this bug can depend on bug 948847 and will be fixed after it is landed.
Depends on: 948847
Hi Enpei, this bug has been fixed after landing bug 948847. Thanks :)
