So, the only solution is firmware update?
Mine is latest firmware. So, I need to wait?

Yep,

in N9005XXUGNG1. it is definitely solved.

The Note 3 now is my first smartphone, since the Nokia 9100, that does not give any problem whatsoever.
Not one single bug!

And I guarantee you that I am a heavy user.

Amazing!

Thanks.

But, One Question.
My friends, my cousins... They all have same Note 3 SM-N900 non rooted. Same Firmware N900XXUENG1 (4.4.2). They don't have this Wifi problem.
WHY only me?
If I wait the latest firmware and update, This problem will solve?
Thanks again friend.

Thanks again friend.

IN My case the problem of losing the wifi settings did not come back for a long period now, so I presume it is solved.
The fact that others did not have the problem is just a fact. No idea why.

Lightbulb Different Problems, different Solutions?
My Galaxy Note 10.1 kept loosing my known WiFi connections and password since about a week ago which really drove me crazy since I'm using
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.

This method works with my I337 NI1 Unlocked Rooted.
I uses ES Explorer with Root Explorer enabled.
I went to the "system " folder in the device, scrolled down until I found "build prop" then edited using EX Explorer Note Editor.
Really appreciate and high credit to dajumper work !!

Thanks! Been wrestling with this for 3 hours on a newly rooted Samsung Galaxy Tab S. I knew about that file, but was fearful I'd break something if I messed with it. Once I ran the procedure above on wpa_supplicant.conf everything was written right into the file, and all passwords survived the reboot. Whew!

Edit: While this worked, it did not save any new APs, so I had to repeat the procedure. Is there a way to make this work as intended? I noticed that the permissions on the wpa_supplicant.conf was rw-- (read/write owner), but changed on reboot to rw-rw- (owner and group) Is this correct?

I did a bit more reading, and it seems toggling Sync off/on is allowing wpa_supplicant.conf to be updated properly now. I don't know why this the case but I saw the file size update in realtime when I did. Hoping that this is not something I'll need to keep doing, but I guess it's easier than going into the file system to repair.
