My galaxy S4 connects to any network flawlessly and I can browse the web, etc. but when I press the power button to lock the phone or if the phone goes to sleep by itself, when I unlock the phone, I'm still connected to the wireless network, but I can't browse the web or do anything. I have to disconnect and reconnect for it to do anything (and sometimes it takes 5 mins. to find the network. it says it's not in range 90% of the time). I've set wi-fi to "always on" during sleep and I've also turned wi-fi power saving mode off in the hidden menu but it still doesn't work. Like I said, it doesn't disconnect but the orange down arrow flashes and I can't browse the web, etc. I actually wiped the phone and the problem went away for a few days but cropped back up yesterday which leads me to believe there must be some bug causing it but I have no idea what triggers it. Does anyone have any ideas on what to do?
Are you running stock rom?

Sounds like what I'm experiencing as well!

Hey guys,
Just noticed something odd this last few days. The statusbar WiFi icon is dimmed; but I'm connected on WiFi just fine. I can browse, and the WiFi settings is showing all is OK. As in, I'm still connected to my SSID.
Anyone experienced this? What's the best way for me to pull logs? I'm a bit of an Android n00b.
The particular SSID is on a 5GHz AC channel (pretty sure it's on AC, or at the very least N), on TKIP+AES. I've read that the S4 had problems with D-Link routers on TKIP+AES, but I've got an ASUS running DD-WRT. I don't have any other problem with the other devices in the house on WiFi.
Running WanamLite ROM, with FauxKernel 3.
Thanks!

I should clarify,
I'm connected to my router/SSID; but I can't connect to the internet.
But I'm trying out this new solution people have been suggesting.
I created a guest SSID on my router (ASUS RT-AC66U, on ASUS-Merlin firmware), and I pretty much disabled Intranet access on the guest account, and dropped TKIP.
Let's see if the problem will go away.

Unfortunately there's no option for me to create a guest SSID on my netgear router...
i believe this was/is a bug for the SIII. a quick search should bring you to a thread i was flipping through earlier for my girlfriends S3. I noticed it the first day I had my S4 but havent seen it happen since.
Go to your Wi-Fi, press the menu button and click advanced settings, there should be a option to "Keep Wi-Fi on during Sleep" if you want it on select always

The two solutions provided for that bug are to set Wi-Fi to always on during sleep and to turn off the wireless power saving mode in the hidden menu (which can only be accessed by dialing a certain number). Neither of those solutions work.
No go, problem is still very much there for me.
So far I've:
1) Created a guest SSID, with only AES. Problem is still there
2) Loaded a different kernel (albeit a 9505 kernel). Problem is still there.
I'm rooted, running a different kernel and ROM than stock. I'm on Virgin Mobile i337M (Canadian S4). I've unlocked my phone through the Service Menu, I've also enabled my AWS bands, using the QTPS patch. Though I think this is all irrelevant, because theloneranger08 is running an unrooted phone.
So something must've cause the WiFi sleep issue.
EDIT:
What's the best way to go about logging the issue here? I'm a total Logcat newbie. I managed to set it up on my Mac; but not sure what sort of logging I should be doing. Cheers!

Yeah I can't seem to get it fixed. I actually decided to call AT&T and they are sending me a new phone along with the necessary supplies to send my current one back. Hopefully it's a hardware issue and the new phone is fine. Although the fact that it worked for two weeks with no problems and wiping it got rid of the problem for a couple days leads me to believe it must be some bug in the software. Granted, I haven't come across hardly anyone (besides the people on this thread) with this issue so hopefully it is hardware related. I'll be so ticked if the new phone does the same thing...
I got a new phone and I didn't have any issues for a few days but now it's back. Anyone have any ideas?

Kinda impossible for two phones to have the same exact issue. Which lead me to believe this is a software bug.
Can you verify if you have "Check for Internet service" enabled, on Advance WiFi settings (Settings > WiFi > (tap menu) > Advance).
I restored my phone a few days ago, wiped it clean. I decided not to use this feature (it's off by default; but I had it on when I first encountered this issue), and I have yet to see the problem we had. I spoke to a friend who's a network engineer, it could be due to timeouts to the cell towers, whilst checking internet connection periodically, etc. etc.

No it's turned off. I've tried everything but I just can't find a fix. Is there anyway to somehow log the phone and see what runs when I put the phone to sleep? Is it possible that it's an app doing it?

If you're still having this issue, can you check into your Accounts setting? See if there's any sync error.
I had no problem for a few weeks after restoring my phone to factory setting. Then two days ago, the issue re-appear. The last thing I did was adding a new Google account (secondary account, for work). That's when the WiFi problem started appearing again. Then I noticed the sync issue on the newly added account, I had to uncheck certain options, and check them back again. Since then, the issue hasn't re-appear *crossing my fingers*
Way back in the day, I remember that WiFi indicators would look different if you have WiFi with internet access, but not connected to Google accounts (or have issues).
I know this is different than what we initially talked about; but I guess we're eliminating possibilities.

I do not have the issue, but maybe you can try this.
1. Open phone dialer (Phone App)
2. Dial *#0011#
3. The ServiceMode screen will be open. When it is open. Tap on menu button on top right.
4. Select "WiFi"
5. Find "WiFi Power Save Mode"
6. Press the "ON" button to turn the "WiFi Power Save Mode" off. (It will show as "OFF" if it is off)
7. Your WiFi will be off and on again.
8. Try to reconnect to the Wifi.

Ok i just found out its only doing it at home, i tried wifi and my work and it works perfectly doesnt disconnect and connect, but at home it does, though it never did it before and i didnt change or do anything to my router or my phone which i find very strange.
thanks for the help guys i appreciate it a lot, does anyone know what i can do?
have you found a fix to this yet? I'm having the same issue and getting ready to just return the phone and buy something else. My home network is fine, the other tablets, phones, laptops are having 0 issues, Yet my GS5 is either dropping or something, it seems to run horrible slow and things just time out.

No, and the reason that we don't know is that you didn't provide any useful details about your situation.
If you think that someone can do more than make a random guess implies that you think that there are only one or two possible causes. But most issues, including this one, have hundreds of possible causes. So random guesses are not terribly useful. Nor are we psychic, so the only way to efficiently narrow it down is to look for anomolies in your configuration. Which you haven't described.
You should be providing as much technical detail as possible, e.g. what is your home router model & it's firmware version and configuration details, phone firmware version, any specific error messages, any observed pattern, a logcat if you can and anything else that seems relevant.

Have you tried changing the channel on your router?
Sent from my Nexus 7 using Tapatalk
Change the router channel
Change the router SSID
Default the router comfiguration
Change the router operating mode
Update the router firmware
Move the router to a different location
Use a different router
Unplug your neighbours new 50,000 watt pirate radio station
Update your phone firmware
Buy a different phone
Sacrifice a piece of triple chocolate gnocche cake to the pagan God of chocolate and wifi
All random guesses with roughly equivalent (and small) chances of success.
Or one could try troubleshooting the issue methodically.

Hey guys,
I had this problem before, This is an issue with your samsung device and your ISP. They aren't compatible with each other.
Solution:
You must just block clients3.google.com in your modem/router. You can use Block Web Sites section in your modem/router.
Every thing has a solution.
Enjoy your device WIFI.

I have teh same issue on my S5 Cricket. The WIFI does NOT disconnect. Its connected however I don't have internet connection. Turning the WIFI on and OFF fixes the issue, for a short while until it happens again in an hour. Sometimes I slick on a link and wait and wait just to find out the darn WIFI is not connected to the internet. (probably not even connected to my router properly eg, I cant see my laptop shared drives for example).
This has something to do with saving battery or somthing. WIFI internals shut down, even though the icon on top of the screen still shows I'm connected.

Your phone thinks that your WiFi is unstable and dumps the connection to go back to 4g. Why exactly, who knows, but it's easy to turn off the "smart" network switch. Simply hold down the WiFi icon for 2 seconds to get into the connections section. Right there at the top is the smart network switch section ... just uncheck the selection box. Easy.
Lastly, people like fffft need to get over themselves. The fix for the original poster's question was easy, but since fffft didn't know it, he decided to instead attack in order to make himself feel superior. How sad and pathetic does someone have to be to troll forums looking for opportunities to attack and belittle someone else?

The issue is resolved simply by going to the advanced settings in Wifi and disabling 'Always allow scanning'.
Hope this helps.

solution to wifi disconnect problem
I was looking for an answer to a different wi-fi question when I saw this.
I'm on AT&T with my S5.
Under the Wi-Fi settings I have an option for "Smart Network Switch" which says it Automatically switches between Wi-Fi and mobile networks to maintain a stable internet connection. Anytime a computer says it automatically does something for me; I typically say no thanks. I don't typically like my devices making assumptions of what I like, don't like or want to do. So I have that option unchecked. I never have an issue with the network stability once I've connected to a specific wi-fi connection.
Not sure if that will help you all or not. But thought I'd share.
so under Settings --> Quick Settings --> Wi-Fi you will find a check box option named "Smart network switch", untick it, this should take care of the problem.

Same problem
Hi, I have the same problem. Here some info:
- Device: Samsung Galaxy S5 (SM-G900F), Stock, not rooted
- Android version: 5.0
- Kernel version: 3.4.0-5640614 (2015-09-01)
- 'Smart network switch' is turned off
- 'Always allow scanning' is disabled
The problem started 2-3 days ago. When I turn on WiFi/WLAN the phone constantly turns it back off and on again. Didn't happen before, didn't change anything on the router (I have no access to it ) and didn't install a new app (as far as I can remember). I don't know if it only happens on this access point.
I made a log file (adb logcat) but am not sure if it contains sensitive information, is it save to share online?
The logcat doesn't contain any sensitive passwords.

I'm have the exact same problem.
Samsung Galaxy S5 (SM-G900T)
CyanogenMod (13.0-20151203)
Android 6.0 (Marshmallow)
Baseband (G900TUVU1ANE6)
Smart network switch: disabled
Always allow scanning: disabled
What's happening is as soon as my Wi-Fi finishes authenticating and connects, it is immediately disconnected and tries again. No other devices in my house are having any issues, so that eliminates the router. When I factory reset my phone the Wi-Fi begins to work again, so that eliminates my phones hardware. The confusing part is that I installed a bunch of apps such as AdGuard that could possibly cause an issue but everything worked and this started out of nowhere. Also, I factory reset my phone AGAIN and AGAIN, everything worked and out of nowhere while I was looking at my screen while idling, I watched as the Wi-Fi connection dropped and began the disconnect/reconnect loop...
I'm assuming it has to be a software issue because it only started when I updated to a newer Cyanogen. I'm about to test if other Wi-Fi networks have this problem and I'm also going to look through and post a log.
If anyone has any questions or suggestions that may lead to a fix, PLEASE help!
Thanks
Well I factory reset again, this time wiping the internal storage and everything is now fine. I did look at my logcat and there were Wi-Fi errors but I forgot to post them...
Is there any way to keep cellular connection while using wifi? After enable wifi a while, the cellular connection disconnected and when turn of wifi, it takes times to reconnect 3G. I don't want this delay. I need a function like wifi assist on iOS
Yes, if you have Developer Options enabled (if not, tap on Build Number a bunch of times under About>Software Information and it will display in the setting menu) and choose "Cellular Data always Active".
I haven't tried this myself as I'm usually not connected to WiFi but it should do as it says.

Fantastic. I forgot the Develope Options. Many thanks to you
I was having trouble on a couple of networks with the "obtaining IP address" loop. I had tried various workarounds without any luck and other workarounds were not possible due to me not having access to the router or its settings. After on and off researching, I managed to find the solution that worked for me and I hope this helps others who are in the same situation as I was. I have a Nexus 6P using CM13 therefore this may not necessarily work for others.
All I had to do was switch on "use legacy DHCP client" in "developer options". For those who don't know, "developer options" is a hidden setting that you find when you scroll all the way down your settings screen. If you can't see it, tap on "about phone" 7 times and this will unhide "developer options".
From what I've read, this option is not available on Nougat, only Marshmallow. I'm far from being any expert on phones and their software so I won't really be able to help out any further. I just wanted to share with others, who may be in the same predicament as I was, what worked for me.
Ok I'm going to give this a shot. I've tried calling T-Mobile and OnePlus and they didn't know what I was talking about. I'm hoping someone here may understand and have a solution. I'm trying to connect my WiFi to an access point that doesn't have an internet connection and then use the internet from my mobile data connection at the same time. I have a drone that streams live video. By connecting to it's hot spot (access point), it allows live video streaming. It also allows control through points on Google maps and you can use satellite view. I can't get satellite view because while connected to it's access point, I have no internet to download the imagery. I have intelligent network connection, dual channel download acceleration, as well as mobile data always active (developer settings) enabled. Is what I've explained understandable? Can someone help. I prefer not to use a third party app since obviously the phone is capable of doing it on it's own. Any and all help is greatly appreciated. First time posting, hope I did all correctly.
I'm running 11.0.0.1.1 IN11AA
TLDR: I connect to my drone through access point to stream video and need to use cellular data at the same time.
Hi there
You explained it perfectly, I know what you mean.
Can you create a hotspot with your phone and connect your drone to that?
Your internet connection will still work?
Or is it one way only?
How do other users of drones get around this?
Seems like a huge ballache.
No, the drone itself creates a hotspot that you have to connect to I'm order to stream. Again, I've been able to do this before without having to tunnel or anything but I can't seem to get it to work now. Typically the phone will try to attain an internet connection however possible. If one source doesn't supply it, it tends to use others but I'm this case, it just remains offline. Thanks for the great response, I tried to go all routes other than creating yet another post but I've exhausted all options I can think of.
I think there is a setting in "Developer options" that should solve your issue...
1. activate developer options (Settings->About Phone->Tap "Build number" until it says "Developer options enabled" - it may be you need to enter your device PIN to activate this)
2. navigate to Settings->System-Developer Options and search for the entry "Always activate mobile data" and toggle this to ON
Please note I am using a German language setting, so maybe the entries in English are marginally differing from what I wrote...
