I have a stock galaxy s7, no root, no custom rom. When I wake up the phone from sleep, I often find that it lost wifi connection and I have to reconnect it manually.
I have tested 3 wifi networks and this happens only with 2 of them, so this make me think that it's a modem issue. BUT my previous phones (lg g3s, samsung galaxy s4 mini, meizu mx5) worked fine with the same connections, so this make me think that it's a phone's issue.
I have ''smart network switch'' disabled and also ''bluetooth scanning'' disabled (I read on AndroidCentral that bluetooth scanning could cause the problem, but it's not my case). The problem persists even with the latest firmware update.
Any suggestion? What can I do?
All the wifi networks I tested are 2.4 Ghz, the signal is strong and the wifi channel is relatively free.
I've experienced the oppsite problem.
My Wi-Fi is always on. Either I choose the "While charging" or "Never" option in "Keep Wi-Fi on during sleep" setting in Wi-Fi More menu.
Here I find an article about How to disable background Wi-Fi and Bluetooth scanning in Marshmallow.
But in S7's firmware there isn't Scanning option in overflow menu in Location setting like it showed by pictures.
I'm very confused.

The options that you are looking for are in a subsection inside the location settings. I don't know how the subsection is called in English because I'm italian and I use italian language, but it think it's ''location improvement', or something like that. Also, I have the exynos version of the S7, if you have the snapdragon one maybe this subsection could be absent or in another position.
But to be honest I don't think that you can solve your problem this way... Have you tried to reset to factory settings? Or have you checked if there is an app that forces the wifi to stay awake?
Btw, I did not solved my problem yet. I contacted Samsung assistance yesterday, and they told me that I have to send them the phone for reparation, but I'm sure that it could be solved modifying some parameters on my router... I don't want to leave them my phone for 2-4 weeks, beacuse I'm sure that they would send me it back with the same problem. If I find out a solution I will post it.

Yes, both works fine. I have the Exynos SM-G930F
I solved the problem. I disabled the WOW FI service on my router and the phone never disconnected again. WOW FI is a new service of my internet provider that allows to share your wifi connection between all the customers of the provider, splitting the wifi connection in 2 separate connections, one private and one public. For some reason the S7 didn't like the second connection.
Samsung S7 WiFi forced to sleep
Hi
I've been having this extremely annoying condition too, since the last software update.
I came to the conclusion that it was some kind of aggressive power management setting that was putting all kinds of apps to sleep.
Today.... I think I might have found a solution... I say might, as it's only been a few hours..
So I've done is this..
Go to settings.
Search for "Battery"
Click on the three menu dots in the top right hand corner.
Click on "Advanced Settings"
Turn off "App Power Monitor"
So far, so good.
My WiFi stays connected and the 2 VoIP apps and Text-to-voice app are alive and well.
Curiously, my battery drain doesn't seem affected.
I'd be interested to know if this solution works for other people.
Good luck.

Ever since updating my Moto G to KitKat wifi remains on all the time even if I select 'Only when plugged in' for the wifi sleep policy. It was fine while on Jelly Bean. Anyone else have this problem?

i had the same issue and posted the question here in the forum i got some replies, but nothing helped. here is the link to my thread
http://forum.xda-developers.com/showthread.php?t=2608546
hope some one responds to our issue.
Interestingly I've solved the problem, on my phone at least. I switched from ART back to Delvik runtime as a few apps wouldn't run and now WiFi is switching off when the screen is off.

I experienced what I believe to be the same issue with my N5 - I used to have my wifi policy set to "Never" so that wifi would be turned off when the screen is off and it used to work. Recently I thought I'd give ART a shot and after using it for a while, found that wifi stayed on regardless of what the policy was set to. I disabled all background syncing apps (google account, fb, etc.) and all location services and the wifi never switched off the way it used to. I also tried wifi optimisation on/off, avoid poor connections on/off, and always searching on/off but nothing fixed it.
Even after switching back to Dalvik though, it still doesn't work properly. Currently doing a factory reset and will see if it works after and report back
Any solution yet? Mine does the same and I tried everything, from turning off location to uninstalling maps (seeing they have an option to activate wifi) to factory reset and nothing helped.
Advanced Wifi Settings
In Advanced settings is Scanning always available
ensue this is off,otherwise location services will look for networks even if wifi is off,so presumably it turns it on to do this!

Like I said, I have tried all settings. Scanning always available is off and even disabled location services.

Finally my phone alive now with fastboot downgrade with 4.3 brazilian retail version .only problem is that wifi is not working.plse help
please check the router setting of which the device connect access to internet, under wifi setting in the router homepage check if the channel is not selected to AUTO, please choose channel ex: 1,2,3,4,5 etc and connection frequency to single band i.e 20MHZ or 40 MHZ, but it might also work in auto band mode selection. I had the same issue on my HTC A9 android version marshmellow but when i changed the setting it works fine.
In my experience with Stock ROMs, this issue (Wi-Fi always active in Battery Stats even though sleep policy is set to: Never) is caused by an installed app.
Viber has a setting in General > Wi-Fi sleep policy.
Not every app will have such an option, but check. All you can do if the issue persists is to clean install ROM and one by one start adding your apps to see when the problem reoccurs.
There may be apps (or an xposed module) that will allow you to stop apps changing the Wi-Fi sleep policy. I've not done any research on the topic.
Wi-Fi Scanning can be enabled or disabled and does not have an affect.
Hi,
like in subject is our N5 supporting wifi roaming/changing access point based on signal strength? I have two access points with the same SSID but on different channels. My laptop is switching between AP from upstairs and downstairs and iPhone 4S I had before N5 was switching too. Unfortunatly Nexus is not... Is it supported by our phone or not? Is it at all supported by Android OS?
BTW I wanted to ask another thing related with wifi. I changed wifi option "Keep Wi-Fi on during sleep" to "Never" but it's not turning off when I put my phone in to sleep. How long does it take to turn of wifi after locking phone? Could you check Is this option working for you guys?
Thanks for all answers, Zibiksior
Anyone?

hello and sorry to be late but i didn't actually had nothing to say but i'd had the same issue.
Yesterday frustrated by the roaming not working i tried to set wifi network frequency on n5 wifi advanced settings to 2.4ghz only and volià, wifi romaing seems to work correctly: as i change the room n5 suddenly changes ap without loosing connection.
can anyone confirm?

I will check it today at the evening and report back.
EDIT. Nope its's not working for me. @Riekr what Rom are you using?
Sent from awesome Nexus 5
Stock ROM, anyway I'll check further as it seems to switch from one ap to another but not vice versa. Please also check that all parameter are the same except the channels (as per specs) and that the channels does not overlap with WiFi analyser (to improve performance)

Yes I have the same configuration. The same ssid and pass in both AP's. Only chennels are different and not overlapping also. I'm using now purity rom with Linaro kernel.
Did you manage to fix this? I'm having the same issue.

That option does work and will switch over to your data connection when the phone is asleep. There is an option in the WiFi settings called "scanning always available" which will prevent the WiFi chip from ever truly disabling itself however.
From what I can tell my Nexus 5 changes fine, however I have only tested it on the same router.
I believe "Keep Wi-Fi on during sleep" to "Never" only turns the Wi-Fi off if there is not an active connection currently using data, otherwise things would get dropped packets, etc. Correct me if i am wrong though.
I have the T-mobile LG G2 D801. Every time I am near an AT&T wifi hotspot, my phone "knows" my location and automatically turn on the wifi and connect to it, even skipping the usual web login agreement. This is the first time I have seen this feature on a none-AT&T phone. Has anyone else notice this?
Very interesting ability but how does my phone knows I am near the AT&T wifi when my wifi is already set to off?
How do I disable this feature (none-rooted phone).
I haven't noticed this on mine; I'll have to watch for it. There is a "scanning always available" setting in the Advanced Wi-Fi settings, it is enabled on my phone.

Yes, this feature was turned off and my phone still automatically detects I am near a Starbucks and connect to the wifi there.

I ask because it manages your wifi and can turn it on automatically good app though. Idk what your issue might be then, I've never had an issue like that.
Is this phone which I just purchased able to be upgraded to Lollipop ROM. I did complete the Kingo Root but that is all so far. I am having WiFi issues with the stock ROM,keeps disconnecting from my Asus router. Also, I only have a 300megbyte data package for this phone and was wondering if At&t is able to disable my WiFi on the service,sure seems strange that all of a sudden my phone wont stay connected to my Home Wifi .it just started dong this 2 days ago. Thinking maybe they can cut my WiFi off and trying to make me upgraded to more data by making me use up my small amount by using the 4G signal. They just sent me a email stating that I am already at 75 percent of my 300mg and I could purchase more date if I wanted to. One more thing, TWRP does not seem to support my phone since I could not find it in the list when trying to install there app. Any help would be appreciated.
I had a similar issue when using 5ghz WiFi and ultimately had to switch to 2.4ghz and leave 5ghz off... Some things to try (under Settings -> WiFi -> three dot menu -> Advanced)
Set "Keep Wi-Fi on during sleep" to "Always"
Unhcheck "Avoid poor connections"
Set the frequency band explicitly
Uncheck "Wi-Fi optimization"
I only had partial success with the above, WiFi still goes into fits on occasion but overall the stability on 2.4ghz, especially with the screen off, has improved.
As a side note I've started a super thread for the DuraForce here (link) for those of us with the device to share experiences and fixes. I'm hoping that enough of us can band together where issues like this can be solved faster. I've seeded the thread with everything I've been able to put together and any additions are welcome.

Now let me start off with this happens when I was on Verizon and now on ATT and with several different Samsung phones. I have an S22 Ultra now.
Really not into rooting anymore but might get back into it to run better roms and take over Android Auto. I hate AA it's too pushy taking over everything. I stopped using it. I'm old fashioned and not taking calls on my truck I would rather use the bluetooth headset.
Sorry...
Ok onto the issue. So you sitting in the house hotel whatever on WiFi you leave and then phone goes to the network automatically. I have no internet just sits and try's. I can fix this by rebooting the phone or go into airplane mode and out. Then all good to go.
Makes me to never use WiFi on my phone ever. Kinda annoying.
I'm I going nuts or is this an issue across the board?
.
Reset your network settings.
Why go through the trouble of resetting your network?
Go into Settings -> Apps -> Andoid Auto
DISABLE THE DAMN THING. I HATE ANDROID AUTO. It's what I did.

This has nothing to do with Android auto. I was asking about going from wifi to cell network and no internet.
and resetting network settings is an option like @pjaysnowden said.
Thanks
ok so I reset my network settings and will report back after a few days. I was having issues with my bluetooth devices disconnecting all the time and that seems to be better now. So we will see.
Ok well resetting the network and losing all my saved wifi data was a waste of time as I have found resetting the network data never fixes anything.
So still if I'm on Wifi and then leave the wifi then the phone goes to cellular automatically I have no internet unless I power down and back on or airplane mode on and off.
This all started on several different phones and with ATT or Verizon when this 5G crap rolled out.
If I force the phone on 4g all fixed does not do this. Very Strange.
My fix never get on Wifi. LOL
.
Sorry if this was mentioned before, have you tried messing with the "Intelligent Wi-Fi" Settings?
Settings -> Connections -> Wi-Fi
Tap the 3 Dots in the (upper-right and select Intelligent Wi-Fi.
Make your adjustments accordingly

Don't see much in there that would help with cellular network internet connecting when moving off wifi? I did look though.
I'm not having issues with wifi at all. It's the cellular network when going off the wifi.
Ok I just forced the phone off of 5G and use 4G LTE only on ATT. Network is faster and no longer have the leaving wifi issue. As for Android Auto. I removed it form my phone altogether. It's not worth the hassle. It also it not ready for prime time. LOL
5G is not ready for prime time yet... It suxs
Hi, is this happening to you with a specific wifi network or is the same with all of them? Is your WiFi signal strong when this happens?

No this happens no matter what wifi network I'm on. Really a PITA. I switched over to 4G and have not had this issue. Like I said. Did this on Verizon and ATT and different phones. I using the S22 Ultra now.
