[Sony Doesn't care this at all] WiFi Status locked, cannot change or turn off

[Heresy]

It looks like this is a general problem after ICS upgrade for Sony Xperia phone.

I didn't have this problem before even in worse firmware 6.1.1.B.1.10, but after using 6.1.1.B.1.54 two weeks, I have the problem now...

I can connect to AP after boot.

After use for a little time, the process "wpa_supplicant" start running, and never stop, just like the screenshot below (right-top corner).

When the process "wpa_supplicant" is running, I can neither turn off the WiFi, nor make any setting change about WiFi.

What I can do is reboot.

It looks that the WiFi status was been locked by this process.

According the information on the web (reference), this issue can be fixed after delete the file /data/misc/wifi/wpa_supplicant_bagscan.db. (rooted required)

But this file will automatic generated by wpa_supplicant, so the same problem may happens again.

Is there any way to fix this issue without rooted?

I don't know about the rest of you, but after my second factory restart, I haven't had any issues with the wifi, and that was a couple weeks ago...

I think the most important thing is to carefully manage your wifi usage. For example, DO NOT leave your wifi on over night while you sleep. And besides that, I only turn on my wifi when I am actually about to use it throughout the day when I am at university. After I'm done, I turn off the wifi. Not only does this help prevent the wifi issue from popping up again, but I also extend my battery life for MUCH longer so that now the Xperia U actually lasts ALL day!

I don't know if the original wifi issue had officially been fixed or not, but careful system management has worked for me so far and the problem hasnt returned yet...

Hello, for those who have the bug of WIFI that locks, here's the solution: Pre-requisites: must have a mobile phone with permissions of root Install a file explorer that you can access the system root (Examples: Root Explorer or ES explorer) After:
1) Turn Off the WIFI 2 (open the file explorer and go to /DATA/MISC/WIFI folder and delete the file wpa_supplicant_bgscan.db 3 Connect the WIFI (this will generate a new file wpa_supplicant_bgscan.db) wait until the new file being created. 4 Go to the folder /DATA/MISC/WIFI , select the new file wpa_supplicant_bgscan.db and change all their permissions for "read-only". Congratulations because the bug irritant of WIFI has been solved.

Ok i have had the wifi problem for ages but recently it got worse...

BEFORE: it would only mess up (stay connected even when out of range, unable to turn off wifi etc) only while using one particular wifi hotspot at university - it was fine at home and other places.

NOW: At university, it connects for 5 or 10 minutes then wpa_supplicant comes on and it is locked, and it even happens at home.

SO i decided to root my phone and follow the instructions above to fix...

HOWEVER, I dont have that file wpa_supplicant_bgscan.db   I have searched for it and made hidden files visible but its not there..

What do I do to fix it?? The phone is useless without wifi.

Although we understand the trouble some users have with this issue the company has taken the decision to not release any more softwares for the Xperia U.
