WiFi hangs and drops - Galaxy S 4 Q&A, Help & Troubleshooting

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 ?

Recently loaded custom rom now phone gets hot

Hiya, Yesterday I loaded Damage Control v2.08.1 and it's been running pretty smooth. Just in the past few minutes I've noticed the phone getting hot around the battery. I've never felt this phone get hot before. A few minutes later it cut off. I had to press the power button to get it to turn back on. Everything seems fairly normal now and it doesn't really feel hot anymore. Has anyone else experienced anything like this? Should I try a different ROM?
I think this is a random thing..ive had it happen a few times on diff roms etc..

The ROM is fine I use it.
maybe you should take it to sprint and say it is getting really hot. They will trade it in for a new one. In less your over clocking it then you should know why it is getting hot. But I believe it is a hardware error.
Thanks for the input. The main reason I posted is because I used stock 1.5 for 5 months before loading a custom ROM and never once felt the phone get hot.
As long as it's a common thing I'm alright using it that way.
I ran into a similar thing when signal was low. A workaround is to turn off wireless triangulation in the location menu. Also turning off "always on" helps a lot, I forget where this setting is. I was hitting 43c a day before these changes, now barely get over 30.

the always on setting is in location (it turns GPS off)
Line got really hot a couple weeks ago. At first I could not figure out why, but after looking at everything I realized it said I was roaming. O was in a location I was always at and never had s problem before. It said I had been roaming for 4 hours. Restarted the phone and the problem was fixed.

I´ve tried everything, my S4 won’t go to DEEP SLEEP

Hi there, I have this problem; my AT&T GS4 does not use the deep sleep state. I have made some research, and from what I understood, this problem has to be a result of any program that keeps triggering the phone to get awake.
So, I have the phone unlocked, rooted and ALL the sensors off, expect from gsm signal. With titanium back I have uninstalled the programs that I´ll never gonna use (mostly AT&T bloadware) and frozen the ones that I don’t want to use right know, but maybe by deleting them I would get into a problem (like S-Voice) or just because some day I would like to give them a try. Finally, there are the programs that I would like to keep, but I don’t want to let them make any cpu use while I am not using them. I used an application called Greenyfi, a good example of why this program is the best for the last propose, is the use of programs like google maps, in where I do want to use it, but, just when I open the app. Also, I used the app “Autostarts” to prevent applications to start after some events (like startup, state change, etc..)
With all that been said, I am steel not getting deep sleep, in any situation. I´am not saying that my battery life is bad, I think I can get easily 4-5 screen time use. But, by not getting into deep sleep, the phone is allways using the cpu at 384mhz, so the battery goes down in a range of 1.5 to 2 % per hour (10 hours of no use and 20% less battery).
SO, for you to see the problem better. I did a little experiment. Restart the phone, put it into flight mode and let it “sleep” for the night, the results are attached.
PD: Whatsapp isn’t the problem; I can froze it and still 0% deep sleep.
PD2: Sorry for the language, I forgot to change it.
Get BetterBatteryStats app. It'll tell you what's keeping your phone awake. Look for partial wake locks.

ok, I did it, and BBS says that in partial wakelocks there is no major problem (20seg out of 1 hour the worst app). BUT, in kernel wakelocks, shows that "MSM_HSIC_HOST", is using the exact amount of time since the phone was turned on (1 hour). So, it has to be this. I´ve reading a huge thread of many people having a similar problem (mmsm_hsic_host been the process that wakes the phone most, but not using ALL the time, but considerable time (between 50% to 10). I ‘keep reading until I found a solution.

Bro! I am so trying to get my s4 to not go into deep deep sleep, to be able to have a switch or click here button to be able to toggle that option would be the way for me to continue to use unlimited 4g tether because i was told to use hotspot vpn shield to prevent tim lee mobile from sniffing my data to see if i were tethering ! Although the vpn just told me that the application goes in to deep sleep (aka it turns off!) That's right folks the application turns off without you knowing until it's too late, so let see where to go from here. ??

Keep it plugged in and in developer options click stay awake and it should stay on when plugged in.

Yes if you have developer mode to stay awake while plugged in and want to turn the screen off at any point just hit the power button to lock/shutoff the screen.

well the hotspot shield vpn by anchors inc. makes thier app shut down when the phone goes into standby said the tech guy today because it still shut off.
so i suppose i need to prevent standby
ok i got to the bottom of this , hotspot shield vpn by anchors inc.are liars , the tether app auto prevents standby and i also i enabled the developer stay awake optiion. it turns out the application will turn off when no data is being sent for sometime and i have a feeling that it is in their favor for whatever reason otherwise the app would have an option to not shut off
now i was looking into getting termenal_ide to ping google every so often say every 3 or 5 minutes ,
i ran it and it was pinging like a mad man , more then once per second , i though i might get blacklisted for a false ddos

Wifi Issues: Keeps Turning off & On

I've seen other people having issues with wifi but haven't read of anyone finding a fix. I'm watching the on/off switch go back and forth as my G2 continues to try and establish a connection. It connects to my router for a second, then disconnects...This has been keeping up all day.
Any suggestions?
Already reset my router. Tried to WPS push button method.

Did that. Nothing. Also tried to connect to the public wifi at work, same problem.
turn off battery saving stuff like switch off wifi when not using
Has anyone have a solution to this?
My G2 did the same thing as the OP says. It will turn itself on and off (about 5 second between each on and offs) but ONLY if the bluetooth is turned OFF. If the bluetooth is ON, no problem whatsoever. I usually left my bluetooth ON because I have a bluetooth headset and I want it to be ready every-time I want to use them. But, this night, when I turn off the bluetooth, the wifi keeps going on and off, and yes, battery drained and no internet connection for me
Please help if anyone have a solution for this. I'm in stock rom (D802) 4.4.2 rooted, with xdabbeb's camera mod, the only "root" apps that I've installed so far. Reboot and full power off is the first thing that I do, still no cure.

Sorry for replying to an old post, but I have exactly the same problem here, only difference is that in my case, charging stoped at 66%. I changed the battery, the charging issue fixed but still have the wifi/bt issue.
I flashed stock kk rom, and 3 custom roms with kk, lp and mm base, nothing..
Thx for any help.

Note 2 wifi problem: Please Help.

My wifi was working very well. One day suddenly it went off. Initially I thought it was a connection problem, but eventually I discovered that the wifi toggle switch refused to start. It was stuck.
I did not upgrade or change anything (Currently running stock android 4.3.) In a bid to correct it I even did a factory reset. But wifi issue remained.
Did everything mentioned in various YouTube videos. But in vain.
The only way I can turn it on is by switching off the phone, removing the battery 4 a minute and restart. Wifi worked but to 5 to 10 min only.
Removing battery every time 2 start wifi is nuisance.
Pl advice.

I would advice you to do the following
=>Disable all power saver settings
=>Remove any battery saving App
If it doesn't work try
=>Installing the newest Official Firmware from Samsung(4.4),Download it from the sam mobile site
If that doesn't work well then i cant help you anymore
Hope that helps and hit the thanks if i helped
Dear Sammy,
I did exactly the same. Installed the 4.4.2 but a new problem has emerged. Wifi shows connected. I can also see the white wifi icon on status bar. But in fact is not connected. Can't open anything. Not even router configuration ip address.
To make sure it was not a modem/ router issue, I checked d connection on another phone. It was working perfectly.
Here too I tried switching off for couple of minutes but on start it just shows connected when it is actually not. (Confirmed several times on other phone)
Plz help.

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.

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.

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.
