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?

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.

Update: My phone works fine on 5.1 ghz bands but not 2.4 bands. Very weird...
My S4 keeps reconnecting to my wifi for some reason. I get the toast notification saying "Connected to <SSID>" that will sometimes pop up every 5-30 seconds, but it never goes more than 30 minutes without doing it. My router is an Asus RT-AC66U. I've tried forcing 2.4Ghz only, 5Ghz only, changing the preamble (short, long, auto), changing the channel (manually specifying each channel, and also tried auto), and even manually assigning an IP address on the phone. None of these things help.
I have "check for internet service" under the advanced wifi options disabled, and also have it set to keep wifi on during sleep.
The phone shows Very Good signal quality. Using wifi analyzer shows a signal strength of between -45 to -68 db, depending on what room I'm in, so that's definitely not the issue. It even does it sitting in the same room as the router. No other devices have an issue, including my roommate's S3.
I can fix it by turning off wifi power save mode (*#0011#), but then my phone heats up quite a bit whenever I'm using it, and my battery drains at 10%/hour even when I'm not connected to wifi. So that's not really a solution.
Is there any other fix for this? It's a bit ridiculous. I'll load a webpage and it'll interrupt halfway through when it re-connects to wifi. Since it keeps reconnecting to wifi, it causes all the phone's connections to be re-initiated, and also seems to trigger Google Services to update the phone's location. This results in Google Services (NetworkLocationLocator) holding a wakelock for 1/3 of the time.
So it seems the problem was IPv6, specifically IPv6 that autoconfigures. All the wifi networks I typically use are dual stack IPv4/IPv6. What I'm guessing happens is that the phone doesn't wake up for some of the IPv6 broadcasts, and then the phone reconnects to fix this once it realizes it's out of sync. Turning off power save mode means it gets all these packets and doesn't have to reconnect.
So I fixed it by having Tasker disable IPv6 on wifi whenever it connects to a wifi network (it's re-enabled if you disable wifi or reboot). Run this as root:
echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
I wonder if this is just a bug in the chipset, or if it's a driver issue that can be fixed in a later update.
I had the exact same issue with mine (same router) and solved it by disabling WMM APSD in the router settings. Wireless>professional tab>5GHz drop down box>Enable WMM APSD>Disable.
A guy in the other GS4 Q&A forum gave me this solution and I haven't had an issue with it since.
I have this same issue... so when my Wi-Fi is dropping like that, I disable the Wi-Fi power save mode by dialing *#0011# then pushing the menu button and selecting the Wi-Fi option from the pop-up, the psm button is there. Fixes it every time, doesn't stick thru a reboot tho.

I'm running SACS Custom 7.1 with Faux kernal, and since I update to 7.1 from v7, my phone doesn't save any wifi profiles I connect to. Another thing I've noticed is no image shows up when recieving a call, so I have no idea who is calling. I got a 3rd party caller id from the market to fix that, but still a strange issue.
I am experianced with phones, but haven't posed enough here to post in SACs page, so any ideas would be helpful.
I tried looking at settings from 3minit or XPOSED, but nothing has changed since V7, so I'm wondering where to look.
The wifi profile shows up in data/misc/wifi/wpa_supplicant.conf, but only the one I am connected to at the time. If i disconnect and reconnect I need to re-enter the password.
Not important but annoying.
Thanks for your help in advance, you guys are awesome!

Wifi issue is faux kernel flash a different kernel. A module from xpose is the culprit sorry I forgot which one was it. To solve all your problems just do a clean install of v7.1 and when doing that make sure you click stock kernel or flash a preferred kernel. I dont use xpose so I dont have that problem so its your choice if you want to use it just read like 10 pages from the thread to find your answer.

I have to do this same thing and it works for me perfectly. A little bit of a hassle after reboots, but it works. I sent this to Samsung and they've opened a ticket on it (reportedly) to be addressed as they've had a lot of complaints about WiFi areas with multiple Access Points.
Every now and then my Nexus 4 forgets (?) my home and work wifi, and a re-scan does not even show them in the list of available networks. The only way to find them again is to reboot the phone, and then all connections work fine for a couple of days, and then the problem repeats itself. The problem seems to happen whenever i switch off WiFi and then switch in on again. If I do that, only a reboot solves the problem.
Is there a way instead of rebooting, to just restart all network services? I found an app that says that it does that but it does not work (https://play.google.com/store/apps/details?id=com.dazbradbury.restartConnections&hl=en)
Any other app, hack, setting I could use?
I am running the latest Cyanogenmod (android 4.2.2) with Kernel 3.4.0-perf-g4857f9b
Thanks all!

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.

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.

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.

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.

Well I know that Smart Network is turning off wifi.. problem is that i have a fiber at home!! So what kind of problem smart network finds on my broadband?? ?
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...
Hoping someone can help me
My S7 Edge WiFI connection is playing up. My phone is fine on data network but only when connected on WiFi (Have tried other networks too) it has some serious problems like,
- Whatsapp notifications not received unless I switch to data connection or open the app
- Trouble loading internet applications, they just hang randomly but if I switch to data then they load
I first noticed this when I switched over to SuperManROM, however I have since reflashed the previous ROM I was using and still have the same issues. I've tried custom kernels and stock kernels and no difference.
Is it simply a faulty WiFI chip in the S7 Edge or coudl it be something software related? An important point to mention is that for the SuperManROM I had to update the bootloader and Modem, but I did downgrade them again to see if there was any change
Please help
Having the same issues. Tried multiple Wifi networks, same issue. Shows I'm connected to it, but no throughput. Tested the same networks on my laptop with no issues.
I'm using SuperSU.
This happens to me too, but only when I enable power saving mode, could that be your issue?

Well I thought it fixed it, but it doesn't look like it did. Rebooting the phone to see if that helps
Update: even after a reboot no luck.
On cell data no issues. As soon as I connect to Wifi, I lose it.
Update 2: Had a system update available. Tried to install it, and after the phone rebooted it told me the update failed, but the Wifi works okay for the moment. Honestly no clue.
You guys got any VPN profiles installed or anything?
Settings - More Connection Settings -> VPN
