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

[Q] Lollipop WiFi issues - takes long time to turn on or not turning on at all

I had CM11 on my Nexus 4 and did a full wipe, then flashed the official Lollipop image (using flash-all.sh script). The process went smooth, without any problems.
Now, I am having WiFi issues. When I turn on WiFi from quick settings it changes the icon, but doesn't connect to the network yet. If I try to access WiFi settings it opens them up, but I can see only the actionbar and a blank white screen. No networks shown. Sometimes I even get "The app is not responding dialog". It sits like this for about 30-60 seconds and after that it connects to the network and I am able to access WiFi settings.
Sometimes I can't turn WiFi on at all. Quick settings don't change the WiFi icon to the ON state. If I try to turn it on from the Settings, the switch does literally nothing - not even "Turning WiFi on..." shows up.
I tried to reflash the system - still get these issues. Tried reflashing just the radio module - didn't fix it. No idea what to do. KitKat worked just fine.
Does anyone else have similar problems?

Same issues, but on a Nexus 10.
I have exactly the same issues as you, but on a Nexus 10. Running LRX21P 5.0 Lollipop.

+1
I used Wugfresh 1.9.6
Downloaded and installed LRX21T
Did a complete wipe (cache and factory reset)
Did a selective restore of ~75 apps from Google backup
Played with the machine for hours.
Rebooted, now got no wifi
Anyone suggest a workaround?
EDIT: I came across this post in the Nexus 5 Thread , where he suggests changing your router's channel to something below 12. I changed mine from 13 to 8 and now wifi seems to be working.
EDIT2: Sadly the above was a red herring. The problem seems more complex. Hopefully Google will release a fix soon

I don't think my problem depends on the available WiFi networks. But thanks for the response.

I have the exact same issues, Wifi doesn't turn on at all. It doesn't matter if I press the quick settings button or the button in the menu. It says Wifi on, but nothing happens. After the screen goes dark, Wifi turned itself off again.
Any suggestions? Thank you!

I'm having the exact same issue. Wiped with ADB and flashed LRX21T factory image from Google's website. No error codes during flash.
Wifi is great - if you leave it on all the time. As soon as it turns off, it will NOT turn on. I get no error message, no timeout like it usually does when Wifi isn't working properly, no crash report. Nothing. Just a stalled Wifi acting like it's turning on. If I exit Wifi settings page, and come back, it shows as being off. Turn it on, and it just hangs the same way.
So frustrating.
It's for sure not the network I'm on, as it also doesn't turn on when I'm not near Wifi, or when I'm at a friend's house. Rebooting the phones makes the Wifi work again...until it turns off for ANY reason. Then we're back at square 1.

I'm having this same issue...
My WiFi seems to turn itself off. Then there is no way I can get it to turn back on unless I reboot the phone.
Very frustrating.

I have the same issue.I sideloaded the OTA and everything went great,no errors during the installation.I was on stock 4.4.4.
When I turn on the Wifi it takes around 30 sec to connect to a network.If i click on the Wifi menu in the setting it usually freezes or I get a black screen.After that Wifi works fine,but another thing I noticed it doesn't remember new networks.I don't know if a factory reset would help...

Anyone find a solution yet? Did a factory reset eliminate the problem for somebody?

I got the same thing. Currently, I'm using Power Toggles to do the on/off setting.

Are you saying that Power Toggles fix the problem?

I'm facing a different issue. Whether I have WiFi on or off, it always appears active in the battery usage stats ('scanning always available' is off)
WiFi was off when the screen was off from about 3 am to 2 pm.

I am having the same issue. very frustrating. it was working perfectly last night on my home network, but now it wont connect to my work network. it has the same issues as everyone else. the wifi toggle will turn on, but it will not show any networks. then after a couple of seconds it will turn itself off.

^^i am having that issue as well. the battery usage stat page is showing wifi as on even though it is off.

Have the same issue. After some standby time, turning Wifi on again, it showed me networks where I am not close to anymore and didn't show me the actual networks where I am right now. This seems to be a serious bug that needs fixing. I don't want to reboot my phone to fix it. Didn't Google delayed the Lollipop-Update because of some Wifi issues?

I have all the symptoms listed in this thread. I filed a bug report too: https://code.google.com/p/android/issues/detail?id=80028&q=LRX21T

Found this thread when this problem popped up for me after flashing the factory images one by one. Might try to find a source-built ROM using a later version to see if it got fixed.

Android N wifi issue

Decided to install N a few days ago and test it out, everything was going fine but after returning home from work today my wifi will not reconnect. I've added the info for my wifi back in several times, the phone says the network info is saved, but it never connects or even appears in the list. Don't really feel like wiping again right now, so did anyone else run into this and manage to fix it? Any ideas? I've already tried all the usual stuff, but no luck.

Apologies if this is a silly response but is N official? I thought it was a beta? I'm assuming if that's the case then you'll get variable success with connectivity and functionality.
Do got have the most up to date vendor and is the kernel your using optimised correctly or should you expect issues!

Definitely not a bug. I have been using the preview since day one, and WiFi is working completely fine. Here's what you can try - wipe cache from recovery. And then if it still doesn't show up, you may try resetting your router settings.
I have faced such issue, but that would be subjected to all my devices connected to that specific router. Caused generally by lousy internet connectivity, or some router issues.

I had already tried doing both those things but the problem still persists. I guess I'll just have to try a factory reset or wait for the next update and see if it resolves itself.

The next update is near. In case you can't wait, factory/reset would be good option.

Went ahead and rolled back to MM and everything was working well, then I reinstalled N and wifi was again working without issue. I just returned home from an interview though and wifi will not detect my network again. SSID is still saved, but won't appear in the list or connect. Did a cache wipe from recovery, re-entered my wifi info, reset modem and router, but still no luck. So it appears to be something that I can replicate, and only with N. Here's hoping the next update fixes it.

I'm on the N beta preview 3, and my wifi will randomly stop working on my 6P. I have to switch it back each and every time. Also, when I return home, my 6P won't automatically reconnect to wifi like it did on MM. Definitely seems like a bug.

I am using the latest preview. Wi-Fi won't connect. It shows both the 2.4 and 5 ghz options as saved, but it won't use either one. Older version of Android connects fine to same router. I have a NetGear router.

same issue
Yes I would like to report having this issue as well on the 6P in N beta. I have a 5x on MM in one hand 6P on N beta in the other . 5x has connection fine 6P does not using 3 different routers.

Android N on 5x experiencing same issue. Any resolution?

I can report the same. Has anyone discovered a fix?

Mine works well however if you turn it off and then travel away from your router with wifi off; it will fail to reconnect upon returning to your home wifi and turning it back on. Do you ever turn your wifi off for an extended period of time?

WiFi Issue
Don't know if related. In my case, cannot turn on/off wifi. Even while of it shows the progress bar as if it was looking for networks. Have no wi-fi at this point and unenrolling from the beta isn't sending me the rollback to marshmallow. This on a Nexus 6P

Temporarily fix
I found a temporarily fix till the next update (hopefully) fixes it. Hop to advanced setting and click on wps button. Wait for 5-10 second then click cancel. Hop back to wifi list and you should find your SSID. Sometimes it won't connect even though it's saved and appears in the list. What you want to do is keep clicking on connect. This should help, atleast it does for me. Nexus 5X on Android N.

wifi problem when screen off

Hello
The wifi goes off after 4 to 5 minutes when the screen goes into standby.
Spotify, sidesync, ... cuts
Even the ping no longer responds
If the screen remains on permanently or the phone is charging, no problem.
In the settings, the wifi is always activated
No battery power
Testing on several Internet networks
Has anyone ever had a problem?
thank you

Same issue here. Noticed it happening some time in November.
SM-G935F, stock, on DTM firmware. I can say that the issue started after receiving DTM OTA for G935FXXU1BPJK in Novemeber, and has continued after receiving DTM OTA for G935FXXU1BPLL a few weeks ago.

Been there, Done that, Doesn't matter... I've gone in and reset that setting at least a couple dozen times, to no effect. I've also tried rebooting into recovery and clearing cache before and/or after resetting WiFi Sleep. Nothing has fixed it. Only thing I can think of doing next is a restore/wipe via Odin.

If it occurred after an update, and cache cleaning did not help, the next step is a factory reset or Odin flash due to bad installation.
