1000081 - Entering power saving mode kills wifi

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Settings, defect)

Description

[Panos Astithas (he/him) [:past] (please ni?)]

Attachment: Logcat

Entering power saving mode will disable wifi as expected, but after disabling power saving mode again I never get usable wifi until I reboot the phone. Supplicant seems to die in the attached logcat.

This has been going on for the past few days on my Peak running the latest Geeksphone nightly builds (probably since 4/18 or so). It took me a long time to pinpoint the cause, because I had enabled the setting to enter power saving mode when battery was down to 25%. This would often happen at night and in the morning I had to reboot to get wifi back.

Sometimes even rebooting doesn't fix the issue. Seeing issues with netd in this log, I tried teh following to no avail:

adb shell stop netd
adb shell start netd

I saw some promising log messages, but the settings app kept spinning in the "Initializing..." state:

I/Gonk    (  129): Error connecting to : netd (Connection refused) - will retry
I/Gonk    (  129): Fail to connect to Netd
I/Gonk    (  129): Error connecting to : netd (No such file or directory) - will retry
I/Gonk    (  129): Fail to connect to Netd
I/Gonk    (  129): Connected to netd

Which device did you use ? Hamachi ? The wifi enable/disable is controlled by settings "wifi.enabled". Maybe you can reference the code snippet here.

Connect to netd error should not relate to wifi. Netd is used for wifi hotspot and network statistic stuff. 

According to the log "logcat after reboot", it seems netd is crash due to invalid netd command. Maybe the command is not supported in this version.

I don't have peak on hand, but I can help to check it with my unagi and see if I can reproduce the problem.
