Wifi not working - Galaxy Note 3 Q&A, Help & Troubleshooting

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)

device shuts down affter fully charged

Hi.
I have galaxy for about 4 weeks now. After two I had to wipe the device because of random rebooting while connecting devices via bluetooth and wifi networks. Even now it makes me smash it, but it seems to be not often issue.
After that wiping to defaults, galaxy become turning itself off after fully charged battery. how to fix that? that is really irritating, when leaving phone to charge during night ... and in the morning it is powered off :|
another problem is that I could not access the start-up menu (up or down + home + power) I have only proceeded the setup menu defaults reset option.
please help
Galaxy v JM2/JM1 2.1 update
sounds like a defective unit
but it could be one of those with the comatose bug, the ones that will lock up in sleep mode because of poor signal for data
I don't think it has defect... in that case, it should act similar in the same situations.
Now the problem is different .. :| can't access the downloader/recovery menu and there is only the yellow exclaimer mark telling that there is no connection (I was flashing to 2.2 :| and something went wrong)
does anyone know working solution in case where 3button click doesn't work?
the hair dryer heat, to unlock the 3 button boot into Download Mode to flash again
are you serious about the hair dryer heat? it seems that you are joking ....
please explain me step by step how to unlock the download or recovery mode
-------------
found heating up information .. you didn't joke
I will try that method later
thank you
Another way http://forum.xda-developers.com/showthread.php?t=785201
I've found that after bricking the device. In that solution I must have working (booting) device, which I don't have now....
I have the same problem with a Galaxy S I897. Problem start when I bought a new OEM battery with dock. Happen only when I fully charge the battery and leave the phone alone, if I make a considerable use of battery this don't happens.
I'm using cognition 4.3 and this don't happens on cognition 4.3... I'm going to test today with another battery to see if a problem with the battery or a permanent problem specific of my phone
Check the thread below, might be a GB driver issue which shuts the charger off after full charge and makes the phone run on battery instead:

I've started seeing weird restart issues too. Mostly when i'm switching between wifi and 3g/edge...
I think it's all started after i've flashed 32.50.00.32U_5.12.00.08 radio.
The radio is much better for me than the stock froyo one, as i had a lot of problems getting back on the carrier 3g/2g after being on wifi... This reconnects much more reliably, but also restarts occasionally. pretty bad.
What radio are you using?
my radio is also 0.35

Perhaps you could monitor cpu usage with a task manager? Usually the phone getting hot is a sign of the cpu ramping up.

Are you using a customer kernel?
I had a weird reboot issue on my N1 - found out it was caused by 2 things:
1) I was using a 99 cent car charger from ebay ... somehow the micro-USB connector was just not right
2) I tried a mini to micro usb converter so I could use an old Blackberry car charger and well.... same result.
I might end up shelling the 20-30 bucks for the real-deal car charger.
Charging at home is never an issue - I have 2 original N1 wall chargers and the little docking thing.
still phone get restart

hey guys If try to play gangster on my nexus one ..
if works fine...but after some time of playing game it get restart suddenly ...
my nexus one get restart on NFS shift and asphat 5 too....
i am cynogen mod rom....IS it hardware problem or Rom problem.??
This is a little funny, mine started to restart during power/usb charge as well, (4 days ago it started to do it) I was using stock everything (2.2.1) on it with a unlocked boot loader.
I just ended up rooting and installing CM7 and have not had a reboot on power (but its only been just over a day now).
Kind of funny how some of us had it all start around the 15th/16th Jan.
What would happen with mine. (using stock 2.2.1 from last OTA) This started 16th Jan.
Plug it in to main power, got a text message, open the app to reply (handcent) phone rebooted, got stuck in a boot, pull battery, it booted up but phone removed LauncherPro. installed again, plugged in, got another text, open the default message app, phone rebooted.
Left phone on charge for the night.
No problems all the next day while off power.
Got home, used USB cable for power from computer, phone reboots after opening an app, disabled LauncherPro thinking it could be that, plugged in again and phone rebooted when opening up settings.
Never had this problem before, I then rooted the phone installed clockworkmod and got CM7 installed.
Last night i put it on power and was able to send text messages etc fine.
I had the reboot issue last year. For me it started after I overheated the N1 badly.
After that it would reboot occasionally when it got hot. After a while it would reboot whenever I used the 3G or GPS for more than 5 minutes.
After sending it in to HTC twice they finally replaced the motherboard and I have not had a reboot since.
Moral of the story: Don't overheat your N1.
i think its my hardware problem

hey dude
i have install cynogen mod in my nexus one but still it get restart in some application and while playing games like gangstar ......
it also get restart when we charge the phone...
i think its hardware problem... my phone is not in warranty..now what to do?.
i can open my phone and give some Heat my hot air gun?
The first nexus one I got had that problem, and I got a replacement phone to fix it. Regret it because it had a much better AMOLED without any of the redness tinges that all the other ones I've gotten have.
It's a hardware problem.
I had the same issue, it started almost directly after I installed MIUI rom.
Before that i had CM6 so I just went back to that rom and the issue was solved.
I did't care because I prefere CM instead of MIUI.
Get the last_kmsg and see if "ARMV9 Crashed" shows up. If it does, chances are it's a hardware issue in which case you're SOL.
Right my problem sorted
Found out that it is the mother board, my was re-booting when it got over 37 degrees, was fine till it got hot then rebooted (plugged in or not). Sent it away and now have a new nexus 1, got it up to 45degrees the other day and no reboot. its a hardware fault, nothing you can do apart from sending it away
Using CM6 latest build and have had mine reboot a few times when charging too.. odd.

My phone is down when i discharging

I I bought the phone from google 1 week ago, in the early days works well. But then when I flash franco kernel finds phenomenon if I do not connect with computer or charger, the phone crashes, I tried to flash a different kernel, flash CM.10 still crashes when not charging or connecting to computer. I also tried to flash stock and unroot, but still did not fix the error. I now no longer in the U.S., so I can not warranty equipment.
I think my battery is fine, when i discharging, cpu-z show battery 3940mV, but 3 minutes later the phone hangs, the sreen still on, and it will on until battery down, but no response when touching, push button or connecting computer again.
I really need the help. please

Data and Wifi Disconnect - No Data Connection

Hey Guys,
Got my brand new GS5 on Tuesday this week but I've run into a pretty major data connection issue and I'm unable to identify a root cause for it.
Essentially, when I leave my phone on overnight (and plugged in) I wake up with no data connection. The wifi is disconnected, and even though my phone shows it is picking up the network, I can't load any sites or do anything using LTE - so both wifi and my LTE data connection are not working. Additionally, the wifi isn't only disconnected, the wifi function is literally turned off. When I try to toggle wifi back on, the toggle goes a light shade of green, like it's stuck trying to turn back on, and never turns on.
Eventually I have to restart my phone and it works just fine again. This has happened on 2 of 3 mornings since I've purchased the phone and only seems to happen after extended down time for the phone as it's never occured during the day. I'm thinking of exchanging the phone (this would be my 3rd GS5 as the first one didn't recognize any headphones.)
Any ideas? Anyone else seen this?
Thanks!
Mine does this when I do a fast reboot. A normal reboot works fine, however.
I would hazard a guess it is a software, and not a hardware problem.

[Q] Galaxy S4 I9505 SUPER hot when completely off (& off charge).

Hey all;
Issue 1 : Its almost impossible to turn on.
The times I cannot get it to turn on it also doesn't show that the phone is charging when plugged in (no battery on screen, no led indicator).
If I reinsert battery a few times whilst plugged into a charger it will sometimes work sometimes will not (I've tried multiple batteries on known working charger)
I know when it has worked as the phone vibrates when battery inserted randomly and screen shows the battery charging symbol, then I am able to also turn it on normally.
Issue 2: When charging phone it becomes too hot to touch on the front glass about 1/4 below the earpiece
This is with the phone switched off; with it turned on; same thing but it never gains charge. (fresh ROM flashed, first boot, no connections, sim or wifi)
It also becomes hot when plugged into charger without the battery inserted; assuming strange processor issue?
I tried to charge it from 10%, it reached 35% before I unplugged it as I was concerned the phone would burst into flames; it had become untouchable/almost scalding on the front glass and the battery was absorbing a lot of the heat.
Issue 3: Wifi will not switch on.
Maybe problem with the processor also? although I did not attempt this on a few different stock roms yet.
More details:
So far I've flashed a stock ROM (actually I’ve tried 3 versions so far, two KitKat and one Lollypop); including flashing correct PIT files with each and using NAND erase all just to see if it would help.
I am using Odin 3.09 with good success; I’ve never had a write issue and it behaves itself very well always detecting the phone instantly in boot mode without fail. I've succeeded with all odin flashes of stock roms and booted each one without too much trouble.
The power drain is sufficient that the phone will only stay turned on for a few hours right after a fresh flash (e.g NO user apps; nothing; no sim; no Wi-Fi; NOTHING); after which I have to swap batteries with another (I'm using a working S4 to charge these).
Thanks to all.
