Passwords nobody can ever remember.
I've been searching the Internet for a solution for about 3 days now and I'm starting to think that even here in this thread we have not one but a few different problems, which need different solutions.

My Note did forget the WiFi settings every time it got disconnected, no matter whether I rebooted, changed location or toggled WiFi in the notification bar. In Google's product forum I found a topic with a similar problem on a nexus 5 and the tips suggested were the same as here, synchronisation related.

However, last entry someone suggested examining wpa_supplicant.conf in /data/misc/wifi (you need to be root for this)
Indeed, while file permissons were plausible the file size was zero bytes on my note.
I simply renamed the file with WiFi off then rebooted and turned WiFi on again.
Of course, one has to enter networks and passwords once more manually, but now they're stored again and my problem is solved.

So, if your problems with forgotten WiFis are sporadic, the problem might indeed be sync related and I suggest to turn off Samsung Sync and Google Sync in the Settings for a testdrive.
If, however, your device keeps forgetting Networks all the time or rather everytime it needs to authenticate again, I'd suggest examining the wpa_supplicant.conf.
The latter problem can only be solved with root access or by wipe of your device, I'm afraid.

I examined the file in the WiFi folder and it seems to have worked! Thank you!

I had installed a program called "VidTrim" to edit videos on my phone, and discovered it was messing up my wireless connection. I had the same symptoms as you all did with the wifi password getting deleted, or corrupted. .. when I uninstalled this app my phone actually tried to connect to my wifi automatically but, it failed with an "error failed to connect to wifi" or something similar. Anyway I tried the "build.prop" fix, and the "wpa_suplicant" fix to no avail. It worked after I uninstalled this app, that by the way also installed its own codecs at the time of installation which made it suspect.

On a side note its funny you guys mentioned the "build.prop" fix because, I noticed a few days back that my phone was lagging very bad. I then ran a "top | more" command in my terminal emulator app to show what was taking all of my processing power. I then noticed that 45% of it was getting eaten up by "secure_storage_daemon" so I read up on it and concluded I didnt need it as I dont need encryption to be running 24/7. So I did a search for that daemon which was in "/system/bin/secure_storage_daemon" and renamed it. After that it never lagged again. Now I see where this module could have been triggered by "ro.securestorage.support=true" makes sense to me. So I changed that to false with ESfile explorer with root just to make sure
Sorry for the long reply but I had to share some light for those with the same pain going through these issues. These are great phones but they certainly didnt work out all the bugs. Good luck to you all!

I did this and now everytime i boot my phone up the first time it connects to wifi i get a message saying im in developer mode and it turns wifi off. Not a big problem because i can turn it back on and its fine until next reboot where i just have to repeat the same thing. Still its strange though, i googled it and changed 2 files to ON and the message still comes up. I dont get anything overlaying my screen though which is strange but im thankful.

Does anyone has this problem too?



NOTE3 - Wifi password not being saved

*** Device must be ROOTED in order to delete the files within /data/misc/wifi. These step we’re performed on a Samsung NOTE3 Tmobile (N900T).

I had my NOTE3 for a very long time now. I'm rooted after doing much research I notice the files we're not getting modified when I would enter my WIFI password. By deleting everything under /data/misc/wifi all files and folders this will remove the corrupted files. Once done I rebooted my phone, enter the WIFI password again I then check the files within this folder and now they have all my information about my WIFI. I rebooted my phone to make sure its working and guess what it worked; its now saving my WIFI information.

Follow this steps to correct the problem:
1.Turn off WIFI

2. Goto Settings> General> Backup and turn off the ‘Back up my data’

3. delete all files and folder in the following directory.
/data/misc/wifi ; Delete all the files and folders.

4. Once done reboot phone re-enter your WIFI information.

5. To test turn OFF the WIFI wait a few seconds then turn back ON it should remember everything. Next test is to reboot the phone, this will validate everything is working correctly.
