WiFi hangs and drops

Hi
I'm currently having a problem with my S4 that is driving me mad.
Ever since I got the phone I've had a bit of a problem with the WiFi connection. I've flashed a few kernels and some seems to help the problem more than others but it's still there.
What happens is the phone connects to WiFi no problems. Then maybe after a few minutes of use the phone won't give me any data. If I search a Web page it just hangs and then says unable to display web page. I then have to knock the WiFi off and back and and it cures the problem temporarily.
Sometimes the WiFi connection can be fine and last a few hours without hanging. Other times it can last a few minutes. The WiFi icon always remains on the screen and the arrows act as if data is getting processed but nothing ever happens. The odd time it will also kick itself off the WiFi and reconnect.
It's driving me mad having to constantly knock it on and off. I'm missing WhatsApp messages for hours because of it also.
Is it a common problem? If not the phone
is still under warranty so I will have to send it back but then that's me phone less for god knows how long
Any help would be great.

if you are rooted, flash this http://www.adrive.com/public/8DJWtV/WifiFix.zip
its a fix that sorted out my wifi problems

I think you should revert back to the latest stock and reset your modem. There might be some fancy settings in your modem software that need to be turned off. I read that somewhere but can't remember which ones. Just search on here.:cyclops:

Hi guys, sorry I've just seen the replies and thank you for taking the time
I shall have a blast at both your solutions and report back.
Thank you again

Well I tried the WiFi fix but that hasn't cured my problem. Today I will flash to stock rom and then re-root and see if that makes a difference. If not its off for repair under warranty and the old Nokia 8210 will be coming out of retirement for a few days lol

May be a fix?
1) type *#0011#
2) press menu button and select wifi
3) turn off power saving mode
4) restart
Alternative
1) download terminal emulator
2) type ping google.com

Hi jehbrian.
I've never heard of this fix but I'm willing to give it a go (whats the worst that can happen lol).
Done the above and indeed you get to a point where Wifi power saving mode is on. I've knocked it off and will see how I get on in the next couple of days. It does make sense that the power saving mode could be killing the Wifi every now and again.
Thanks for the tip and have a pleasant day :fingers-crossed:

I had tried that one. It spends about 10% more battery.

Does it?
Surely there must be something else that can compensate for this loss if it means the Wifi actually works. GPS? Bluetooth? Screen brightness?
My phone is on my dock so can't verify the loss of battery.

I've never noticed the battery drain... besides, S4's battery life is bad anyway.

Any solutions ?

Wifi turning off

Hello XDA. I've noticed that my new Note 4 has been dropping the wifi connection while using the Internet. So what happens is the wifi button suddenly becomes grey and I have to press it to enable it again. It works for a while and then it drops off again...then I gotta press it to enable it...
I've discussed this with Verizon and they are suggesting i do the dreaded factory reset.
I have a feeling that I'll be sending this one back...
Any advice from the experts? Thanks in advance.

Are you having this problem at multiple locations or just one? If at multiple locations, I'd have to agree to try a full reset. If at one, could be a router issue.
Just to cover all the bases, you haven't any power management or something like tasker that could be turning off wifi?

No power management software installed and I really haven't used it much anywhere other than my home wi-fi so I guess I should double check it tomorrow on other networks to confirm before the reset.
I had a similar issue with my Note 3 where I couldn't get wifi to stay on no matter where I was and I needed a new phone...that was after using it for 9 months with no issues....this Note 4 is brand new.

If you are using smart network switch option try to disable it and see if its ok

If you can get to settings fast enough try checking for and disabling power-saving,
also since this tab is "new" try to get to software menu and check for and disable any custom governor apps installed
and check for root install, bad/broken root etc.
as a precaution don't immediately ask how to do that, incorporate that process into your next search
as it will like result in more knowledgeable in depth answers.
good luck!
if there is a custom recovery and root available you may want to consider a factory reset, NOT a full wipe.
also inspect the tab for signs of tampering/opening at it's seams. as evidence of a battery swap/replacement gone wrong.
you may also be experiencing a loose battery cable issue similar to other samsung devices notably the galaxy tab 3 10.1

hmmm, okay run it all day while connected to charger, not usb port.
we're ruling out a hardware issue and focusing on a battery problem , maybe.
from what i was able to find on the subject, that seems to be the test.
additionally take account of all existing apps and process that run automatically at boot.
you may be exhausting your available ram which does cause hangs and unexpected reboots.
you can access and disable many preinstalled bloat apps without being rooted.
disabled all the samsung/3rd party ware or at least what you know you don't need.
now if at the end of your day long test the tab doesn't hang and reboot then it has to be your battery.
as a side test place your tab on a table and pound the table with your fist.
if the tab shuts off or reboots it's your battery cable. do that test with the tab unplugged.

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 .

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.

dear lenovo team please help to clear this bug.

hi, today a friend faced the same issue on his Z1, but with a slightly difference. the chrome browser was the only app that could get internet access. SMS and calls are still functional at this point. We have tested many things without success until we tried a simple test. he gave me his 1+1 SIM (german provider) for me (OnePlus3) and i gave him my congstar SIM (telekom daughter company). the 1+1 SIM has not worked on my OnePlus 3 but with the congstar SIM on his Z1 everything worked perfect.

OK in the end the phone have not recognized the right APN settings , so it needed to be set manually

May be you should boot in safe mode and there turn off airplane mode from power menu.

If its an issue of no signals at all for both sims then it might be an old bug where the phone is continuously in airplane mode without showing.
To solve this you have to boot in safe mode( power+ vol down) , then disable airplane mode from settings or power menu.
It might solve the issue. Hope it helps.
