type *#0011# in your dial pad screen and you will get to ServiceMode. Just top the settings touch pad button to the left of home button and select WIFI. Turn off the wifi. I believe that should help. This is a new security and firmware policy that is crapping out wifi connectivity for power saving.
Personally i hated it. :good:

Help: Stucked wifi turning on

Anyone has a fix for this? I attached a screen record. I'm on stock kitkat rooted. This happens everytime I am connected to any wifi network, then after some time, I will notice that I got disconnected and upon checking the wifi, it was stucked on turning on. Turning airplane mode on and off didn't help me. Rebooting the phone temporarily solves the problem. Hope there is a fix. Thanks.
Here's the screen record link: https://www.dropbox.com/s/v2qi183hzozuqzg/SCR_20140806_092403.mp4
Anyone? I can't even connect to mobile data once the wifi got stucked in turning on.

i have the same issue but mine is not rooted what i did i download this one app via google play called WIFI FIXER.. it fixed it.. all you need to do every time you will open your wifi you just need to access that app and open it from there..
i actually talk to tech sup of LG they told me that the 1st batch of LG G2 phone could not handle the new update for kitkat that's why its affecting the wifi and Bluetooth feature of the phone.. its either you let them fix it they will replace the board of the phone or you need to buy one..

Wi-Fi won't turn on after phone sleeps, sometimes

Hi!
My n9005 works perfectly fine, but SOMETIMES in standby when I wake the phone up, I notice Wi-Fi is turned off, while it previous it was on.
When I try to move the knob thing to turn on Wi-Fi it just does the animation and stays like it's trying to turn it on, but doesn't.
I have to restart the phone every time to make Wi-Fi work again.
This doesn't happen a lot of the time, but it's annoying.
Is this a common thing? What could I do to fix it?
Thank you for your time.
Open wifi menu and go to option.
then go to advanced, there is and option "keep wifi on during sleep". Make sure it says "always on"
The problem isn't that.
That's how it is by default.
I would be able to turn wifi on after it turned off if that was the problem.
In my case I need to restart the phone to be able to.
Factory reset and or rom reinstall

I did a factory reset and Odin flash of the same exact ROM that I had by downloading from Sammobile.
The problem is so random and seems to only happen when the phone sleeps or is charging. Sometimes it works for a few days, sometimes it will happen, no WiFi until a restart.
EDIT:
Maybe I should download another ROM from sammobile and try that?
Does that trip Knox?
I have a [Austria (T-Mobile) MAX] ROM (PDA:N9005XXUGBOK6
CSC:N9005MAXGBOK1) atm, I bought the Note 3 used and it had that. But I live in Serbia, maybe I should try the Serbian one in example for my carrier?
The WiFi problem is just annoying at most, it doesn't happen often, but I shouldn't have to restart the phone to have WiFi.
As its an old old problem google it .

I did,
Ive found people that the wifi icon is grayed out.
Thats not the issue here.
Please help me out here. Tomorrow Ill be opening up the phone with a friend to check for water damage if any. Since I bought it used.
If I dont have to do that, please reply.
BUMP
JJEgan has disabled private messages, so I can't really contact him on a solution or what he meant.
For anyone interested, I solved my problem on my own.
Enter *#0011#, press menu key, tap on WiFi tab, tap on the power saving button so it's off.
I didn't experience the same issue ever again.
