Wifi not working

[Cancar96]

So it has came to this....

My tmobile note 3 is suffering from wifi problem which is causing it to turn of and on itselft iin such a loop that it happens every 2 seconds.
Wifi was working fine other day and this happend out of the blue.
It has happened a while ago but it resolved it self.
I was running stock kernel and rom unrooted (sigh....)

I have tried solutions which came up from google search. (wifi scanning and etc..)

I opened up my motherboard but it looks just as before when it was working.

I got a glimpse of wifi action only after phone was shutdown and it was offline charging and after booting wifi was working for 2 or 3 minutes.

Now Im runnning linageos 7.1 rom without google apps so there are no location services causing it to restart.


What might be the problem is low battery voltage not giving the wifi chip enough power to run but just to start which explaing why it was working for a little time after offline charging but I couldnt replicate the solution.

Sorry for misstypes.

If wi-fi works properly when running the latest stock rom, it could be an incompatible kernel or ROM.

Its not working properly on stock rom and kernel.
It seems like its restarting wifi by itself so fast that it cant even do the scan properly.

It loads up wifi netwoks after been shutdown for few hours but it can connect because it starts to restarts again.

Could it be a defective wifi chip? I have come across two Samsung s4 (one sgh-i337 and one sgh-i337) that work perfectly except for wi-fi. With both phones, I toggle wi-fi to the on position, I see the message that it is turning on wi-fi for a few minutes, then wi-fi just turns itself off and stays off until I toggle it to the on position again. Both phones do this over and over so I changed the motherboard and everything went back to normal.

I appreciate you comment,really I do, but replacing the motherboard seems to pricey for this old phone.

I will most probably switch to nexus 6p.

Here take my thanks as my graditude and merry xmas

You have two solution

First one,
1-turn off the phone
2- connect the charger to your phone
3- simultaneously turn on the phone
The wifi should work fine

Second one, replace your battery

The problem comes from the battery voltage which is less than 3.7v at startup of your mobile for old and fake battery which can not turn on the wifi correctly. You can use Ampere applaction to measure the battery voltage (not the current)
