Created attachment 8440528 [details] turning_on_wifi.log Hi, I'm not sure how the phone got into this state, this happened twice in the last two days - I try to turn on Wi-Fi but it does not turn on. Restarting the device does not help. ENVIRONMENT: Flame reference device Version: 220.127.116.11-prerelease Build ID: 20140610200025 STEPS TO REPRODUCE: 1. Pull down the notification bar and tap on the Wifi icon to turn it on, or go into Settings > Wi-Fi and turn it on. EXPECTED RESULTS: Wi-Fi should turn on, and a list of available networks should be displayed. If there are known networks, it should connect to the strongest one. ACTUAL RESULTS: The "Wi-Fi switch" in the Settings menu is activated, "Available networks" shows "Searching..." for a few seconds, and then the "Wi-Fi switch" turns off by itself. (see screenshot) I have taken a logcat of turning on the Wi-Fi, and it being automatically turned off 4 times. Please let me know if there is any information I could provide to help with the investigation and troubleshooting of this issue. Thanks, - Ralph

I don't know if this is the same problem or not. We're having the same problem on 2.0. Wifi just doesn't work. It doesn't seem to be a gecko problem since when I update/flash just gecko and gaia over an old build, it works. Copying a configured wpa_supplicant.conf on /data/misc/wifi and trying to start the service manually (via adb shell start wpa_supplicant) gives the following log: D/wpa_supplicant( 1565): Could not open file /sys/class/net/wlan0/phy80211/name: No such file or directory Before updating, /sys/class/net/wlan0 that file is a symbolic link to a directory that doesn't exist after updating.
I don't think this is a Gecko problem, the problem seems to come from upstream/gonk. For some reason the wlan0 device isn't configured correctly. Can you take a look, Michael?
Ni to youlong.jiang to see if he can help.
Not sure, I don't have access to Flame builds and wifi works fine here on our devices.
With today's build, it seems to be working again.
To be clear - Wi-Fi was originally working on the build that I was using. Somehow, after a couple of weeks of using the phone, the phone got into a state where Wi-Fi would no longer turn on. This remained for over a week after restarting and soft-resetting the phone (removing the battery). After I did a factory reset, the Wi-Fi started working again. I hope this helps to clarify. Please let me know if there are any questions. Thanks, - Ralph
verify with Flame KK base image v162-3, it's fine
I guess we can close this bug as WFM.
