[Q] wifi switches on and off - Samsung Galaxy S7 Questions and Answers

Hi,
since yesterday I have problem with wifi in my S7 (SM-G930F). It keeps turning on and off every second or two. I cannot switch it off because it keeps switching. I have rebooted my device, but it didn't help me. My phone is not rooted, it has stock 6.0.1 firmware. How to fix it? Despite it's impossible to use wifi now, it keeps draining my battery.

Boot to recovery and clear caches, reboot and see how it is then

done. Sadly, it didn't help me.
edit: I've just used this app but it also failed. If nothing help me I will wait till Monday to show it to my coleagues from Customer Support. Maybe they will find solution

I'd backup with smart switch, and factory reset the phone
Or flash the latest stock ROM over the top with ODIN

I think it may be related with some strange wifi:
11-11 11:20:11.682 3462 3896 I WifiConfigStore: " Social WiFi" is a captive portal!
11-11 11:20:11.682 3462 3896 I WifiConfigStore: not authenticated yet

I saw it yesterday at work, but not authenticated. Now it is remembered in list. Sadly S7 has no option to forget networks out of range. Todays we have national holidays, but on Monday I will be at work and try to forget this network. I do not want to change rom because rom from my operator has wifi calling enabled and it is awesome.

Is there any chance that WiFi scanning is turned on? I recently saw that WiFi scanning will briefly turn my WiFi on then off repeatedly (shows with an indicator on top and I hadn't noticed that before). This first showed up when I installed Android Auto since it turned on my WiFi scanning option by default. As soon as I turned WiFi scanning off, the WiFi worked as it had before. It may be worth a look.

I've run into the same issue. Started yesterday, which may have come with the latest PJG update... Not sure.
But it's rendered my phone pretty much useless. The constant toast message popping up, saying "Network connectivity is available" gets in the way of the keyboard and I can't type a damn thing!
Like you, I've found it's stuck with reboots and a factory reset, which makes me think it could be the firmware or modem.
Edit: Disabling WiFi Scanning stopped the errors. Root cause is still unknown, though. I've never had to disable that before...

Yep. It was turned on, but I have it enabled since I bought this phone. Turning off neutralized my problem, but why it was broken for last few days when I haven't done anything with my phone? I rely on this feature because of localization accuracy and disabling it is just temporary fix.
edit:
Guys, one more thing:
do you have "Samsung Gear" app installed? I think this app is forcing to enable and disable wifi. Under localization it shows battery usage as high and it was updated last week

My phone does not have the Samsung Gear app installed. I do use Samsung Pay regularly and that was also updated (engine and app). I don't know how that would relate to WiFi though.

Turning off WiFi scanning stops the constant switching of WiFi. I tried removing the system settings permission from all the apps that had it (even the Google app) but it doesn't seem to have any effect.

I am seeing the same issue, I did not touch my screen in the following video

disabling "Wi-Fi scanning" in location helps.

Hi,
I had the same issue before.
What I did was(Not sure how its displayed in english):
-Settings;
-Backup and Reset
-Reset network settings
I was having constant disconnections from wifi and it solved it.
Give it a try

Did the above solve the problem?

I am using G930F in US on ATT and encountered the same problem in past few days, where wifi kept turning on and off. Was searching this post, and found out that if i turn off wifi scanning i can get wifi to stay off (when i switched off ) and wifi on (when switched to on) and not flip back and forth.
go to settings.
- click on search
- type in improve accuracy
- select from choice
- turn off wifi scanning
Try that and hope that helps.

I have the same problem. The side effect is that it will drain the battery really fast.
As others have mentioned, after I have turned off the WiFi scanning in the location setting the problem is temporarily gone. However it should not be the solution as I really need the WiFi location to work. I don't know what is causing the bug.
P. S. I only see this problem starting from the last week or so. I leave the WiFi scanning location function on since I have bought the phone in May. Mine is Exynos version.

several Samsung devices have this issue.
I and several others have it on a note 4, and some people have also reported having this problem on S6 variants.

The problem is Google Play Services 10.0.84 version. Another cell phones with this version of Google Play Services have the same problem (ej. Google Pixel phone) but not all.

The problem is the Android Wear App. Deinstall the app and wifi works perfekt.
This issue starts with the last update of the wear app.
Hope i could help you.

I tried uninstalling Android Wear but it didn't make a difference. The wifi kept switching on and off.

As mentioned above, it's Google Play Services 10.0.84. Just disable wifi scanning until there is an update. Hopefully google won't take too long to push a fix.

Wifi connection connected but won't load pages

It said connected in the wifi setting and it shows bars but it just won't load any website in the browser .. anyone got a fix for this?
I have the same issue. Tried different combinations of restarting wifi, turning on/off cell data, on/off wifi calling, etc... all with no result. I've also tried on different networks (both public and private)-- it'd start working for a while and then all of a sudden stop and never work again.
Seems similar to the problem here: forums. t-mobile.c om/t5/T-Mobile-G2x/G2x-WiFi-DNS-issue-not-the-4G-switching-one/m-p/831439 (sorry there's a new user no link restriction)
Does anyone have any suggestions?
Thanks

is it specific to the browser or can you not move any data?
Idk, whenever I have had problems connecting to the tmo network, which is a separate issue.. it was always that wifi calling was still on even tho wifi was turned off. Every time I had probs w/ data on tmo network, it's been wifi calling.. Your case seems to be diff tho.
Is it specific to just your network or all other networks? Try shutting off wifi, reboot... then turn it on again? Idk.. just tossing out ideas.
Some found the root cause and I am posting his finding as I do have the same issue and can reproduce the error:
I think I have discovered a new WiFi-related bug in the G2x's software. I have witnessed this occurring on my phone, and have also reproduced it on a store demo unit. I believe it is unrelated to the switching-to-4G problem people are having with the My Account app, since it occurs even if I have set up the Google account on first boot after a factory reset.
The details of the problem are:
- Every so often, the phone randomly gets stuck in a state where it is not able to initiate any new connections that are made using a DNS name. Attempting to navigate to a web site, h**p://w*w.google.c*m for example, will result in a generic failure message.
- However, attempting to connect directly to an IP address instead of a DNS name works perfectly. For example, navigating to 74.125.225.16 will work fine and will load the Google home page.
- When the phone is in this state, using a DNS lookup tool such as "DNS Lookup" from the Marketplace *will* work, even when using the default DNS server address that the DHCP server is giving the phone.
- The problem has occurred for me when data is off and WiFi is on. I do not know if data being off is a requirement, since this is the way I usually run the phone, so this may be coincidental.
- Switching WiFi off and back on again will *sometimes* work to solve the problem, but sometimes will not. When this doesn't work, switching WiFi off, then switching data on, then back off again, and then finally switching WiFi back on again will occasionally correct the problem. However, I have seen situations where none of these things worked, and the only way to get DNS working again was to factory reset the phone.
- I haven't figured out the exact pattern yet, but this issue seems to occur when the phone has been inactive for a certain period of time. I have often discovered that the phone is in this state upon waking up in the morning after leaving the phone on the charger overnight.
- I have, however, found a method to reproduce the problem that seems to work fairly consistently:
1. Turn WiFi on, and data off.
2. Power cycle the phone.
3. When the phone starts up, start the browser and attempt to browse to w*w.google.c*m. It should fail.
4. Try to browse to 74.125.225.16. It should work.
Just wanted to get this issue in the forums to see how many others have been noticing the same thing.
I know that once the device has less than 10% battery it automatically turns the WiFi off to save battery power. Were the devices this was happening on have a low battery?
Fully charged. It even happens when pluged in with the charger.
My Wifi wouldn't even work if I froze it with Bloat Freezer. It has to run in the background for wifi to work. I found that Wifi can get really inconsistent with it disabled.

Same problem here. After about 30 minutes of being idle, as soon as I pick up the phone it tries to connect 2g/4g. The log are saying theres no connection, so it appears that wifi its going to sleep and not waking up so android is trying to connect 2g/4g
Really starting to be a pain
I have frozen the bloat, and I think the problem is getting worse.
Toggle airplane mode is a quick workaround to get wifi to wake up
Sent from my LG-P999 using XDA App
Same thing happened to me, I did 2 factory resets, and it seems it has been fixed, don't really know what causes it.
Sent from my LG-P999 using XDA App
This may or may not be related, but...
It looks like I found a hacky fix for the dns/wifi/4g bug: install "Set DNS" from the market.
Now when I go into market, and display my downloaded apps, it jumps from wifi to 4g then back to wifi as it should, fast.
Whether or not it should even do go to 4g is debatable, all I can say is my 2 Galaxy Tabs had the same behavior.
If everyones connectivity issues are really due to the DNS settings getting wiped out, then this will work around the problem until I/we find the location of the actual bug.
Would you guys having this problem also post it here?
http://www.lgforum.com/forum/boards/general/lg/topics/g2x-wifi-problems
Thanks.
I figure the more people that post there, the more the chances are of LG fixing it quickly.
Work around:
enable airplane mode
reboot
enable wifi
wait a few seconds after the wifi connects, background crap stops
disable airplane mode.
The set dns app looks like a winner. Haven't tried it but that's what's
wrong.
The freezing and other suggestions are all useless crap.
Updates...
I did a factory reset and installed JuiceDefender (I don't know which one worked) but it seems to be all fine now... will update if things become problematic again
I've been having this problem as well. I've always been able to fix it by toggling WiFi off and back on again. I downloaded SetDNS and when it happened again last night I tried that and it worked great.
Glad to see it's a software problem and not a hardware problem.
same problem here. hopefully it won't happen in cyanogen mod

This fixed the problem, at least until the next time I reboot my phone
How do you use SetDNS? This software bug in G2X reboots my router (DGL-4500) sometimes.
Question bout SetDNS app
Does the phone have to be rooted to use the setdns app? I try to use it but it says "Cannot get root. App will not function."

[Q] Nexus 5 - Battery usage shows Wi-Fi always on?? (even when manually turned off)

I'm on a 32gb Google Play purchased white Nexus 5, activated on Sprint. I went through a whole charge cycle yesterday with Wi-Fi off, and under battery usage / Wi-Fi / Use Details / Wi-Fi running, it showed "Wi-Fi running" 17 hours. I never even had Wi-Fi turned on once.
I've been playing with it today, turning Wi-Fi on and off, and no matter what, the Wi-Fi usage time matches my phone on time. It seems according to the battery meter my Wi-Fi is always on. Any one else seeing this? What is the deal?
Go into wifi settings, click the menu button in the lower right corner, go to advanced.
Uncheck "Scanning always available". There you go.
Although TBQH the battery impact seems minimal (especially if it's able to use wifi to get a location lock, as that's much more power efficient than turning on the GPS).
that is because even though you have turned WiFi off, its still available to app to get better location. if you want to turn that off, go to settings, wifi, options, advanced and uncheck "scanning always available"
that will turn off wifi completely. hope that helps.

Go into WIFI settings and click the menu (three dots menu) for advanced settings. You will find an option that makes the phone to scan for networks even when disabled.

Thank you all very much! Will see if it helps my battery life at all!
Thanks folks.
Following my update to 4.4.2 I was experiencing wifi using a lot more battery than normal. I tend to turn wifi off at night, and phone had started using more battery than normal. This fix in advanced settings got things back to normal for me. Battery usage much better. Odd that the update seemed to have set this to on for me.
Thanks a lot guys..this was bugging my head as well..
Hi Guys,
I've just updated to Lollipop by sideloading the OTA.
My battery usage stats say that my WiFi is constantly on and the phone is Awake, even with WiFi turned off AND 'Scanning Always Available' also turned OFF.
What could be going on and does anyone have any suggestions to fix?
Thanks

I had this same issue. I think I fixed it, check out my thread for a solution: http://forum.xda-developers.com/google-nexus-5/help/fix-lollipop-wifi-off-t2947870
Basically, flash Kitkat factory images, sideload OTA, factory reset, and hopefully that resolves it. Nasty little bug.
Thanks
Thanks for reading my post and suggesting the solution you have written up on your thread. I am going to see if somehow the problem becomes resolved within the next couple of days. Otherwise, I will flash back to clean KitKat image and upgrade to Lollipop as you suggested.
When I upgraded to Lollipop yesterday, it wasn't a clean install. I simply installed over my current KitKat config.

Thanks for the reply, but what you suggest is basically how I have arrived at this situation...
1. I flashed the KitKat factory images a few months ago to resolve an unrelated issue
2. I sideloaded the Lollipop OTA update earlier this week, then discovered the WiFi Awake issue chewing battery.
3. I performed a factory reset (from the O/S, not from recovery) 2 days ago and then re-setup my phone, making sure to untick the option during setup which turns scanning always available on.
4. Today, with Wifi turned off and scanning always available turned off, my phone battery stats indicate my WiFi to be constantly ON.
That said I will give your method another try, but beyond that I was considering flashing the Lollipop factory images, will this help?
Cheers

How I arrived at that situation was by clean flashing the Lollipop factory images Maybe try it again? I'm honestly not sure what the difference in doing the two is (flashing factory Lollipop vs flashing factory Kitkat -> OTA -> wipe), but it seems to have done something for me. Also are you rooted? I did not root after following those steps, as all I really used root for was monitoring battery stats.

I had the same issue as well and found it was actually caused by viber app. if you have viber app you can got into the app
->settings->general->Wifi-sleep policy and change it to use device's settings.
If that doesn't help try booting into safe mode and check your battery stats, thats how i found out it was actually caused by a 3rd party app.
A question?
My wifi is always on too as a function of Settings>Wifi>Advanced>Keep Wifi on during sleep>Always.
My question is, when I'm at work I have no chance of connecting to any Wifi networks (there aren't any!), is it going to save my battery turning this off?
Regards all,
Paul.
I have a 32 gb nexus 5. My Wifi is always on. Whenever i try to turn it off, it automatically turns right back on. If i restart the phone, wifi will be off for sometime. But as soon as i go to the drop down menu, zap, its on again. Any help on this? And of course this is draining my battery faster.

============================================
1. Wiping Cache Partition.
2. An app must be interfering with the android system. Uninstall applications like Clean Master, Ram Boosters, Process Killers ,etc.
Your phone doesn't need these optimizers and they are the source of the problem creating problems with the usage, asking for permissions to interfere with the system.
NOTE : Process killers, ram boosters mostly the problem, you don't need to disable WiFi everytime after use, just go to wifi options -> advanced -> Keep wifi on during sleep -> Never and select WiFi freq band as requied.
After this step you need to clear cache again and then you will never see WiFi on top i.e System will function normally.

Nexus 5 Wifi Issue

So I've had my Nexus 5 for roughly around a month and I hadn't experienced any issues others have had with wifi not connecting until now. My N5 will show im connected to my home wifi with full bars, but going into quick settings shows it to be orange. Suggesting there's no data transfer, I cannot use any internet based apps with wifi. I've tried some suggestions, switching my router off then on, rebooting the phone, turning some settings off in the advanced panel in wifi settings. All have failed.
I was just wondering if anyone else has this problem and if anyone has a fix to it.

There was a thread around here somewhere that suggested turning off your mobile data helped fix this problem, I think it was in the N5 General forums.....here it is:
http://forum.xda-developers.com/showthread.php?t=2550690
Don't know if it'll help or not, just saw your thread and had just looked at the other one, figured I'd toss it out there.
Thanks for the reply, just tried that solution but still no luck.
I have a similar problem except that there are phases of wifi not working.
Sometimes I would have around 20-30 seconds of WiFi not working and there would be no data transfer.
Speeds are still fast when it is working however.
I played a little with only using mobile data and no wifi, and everything worked. (Small sample size however).
Seems like this is a WiFi only issue.
So somehow overnight the wifi has managed to fix itself, will report back if the problem returns.
The issue with the wifi returned unfortunately.

Don't know if you've tried this but change your WiFi frequency band in advanced setting to either "5 GHz only" or "2.4 GHz only," whatever your router uses. Might be worth a try.
Thanks for the help, but I've tried changing some settings in advanced wifi settings but it hasn't worked. Even what you recommended I've tried that before and it didn't work.
wifi issue
Also I have the same issue - Im connected to router by wi-fi, home and work and time by time (5x a day) wifi stops working. Wifi is enabled in settings, but there is no connection. Restart the cellphone helps, but after that, maybe an hour, it appears again.
Issue was in 4.4 and still appers in 4.4.1.
Yet did not found how to solve it.
I have the same issue on my gnex running shiny 4.4, but I also had the same issue on 4.3. Tried the wifi options, nothing worked. Unfortunately, no solution for this device that has to last one more week. The double swipe down and tapping wifi gets the connection back, but it is only a work around.
The N5 connects seamlessly to my home and work wifi. A few days ago, I flashed the hammerhead factory image, TWRP and the 4.4.1 update.

The N5 connects seamlessly to my home and work wifi. A few days ago, I flashed the hammerhead factory image, TWRP and the 4.4.1 update.

Hey,
I have the same problem with 4.4.2.(factory rom, no root or not unlocked). Sometimes the wifi not works and get orange. I must put airplane mode to fix it. Its annoying.
But as well happens to me:
When I go out from office or home (where I have wifi connections saved in phone) the phone automatically switch to data plan from carrier. But when I come back the phone stays with data and there is not automatic switch to wifi. Sometimes it help to put wifi off or always airplane mode on/off for a while.
I do not know if it is normal behave of android but I would like have automatic switch to wifi.
I tried to change wifi details (changing bands, etc.) but not helped.
Please help. Thank you.
Is custom ROM or kernel will fix it??
For some unknown reason, as soon as I updated my router's firmware, the problem disappeared.
Updated Android 6.0 solved the issue

So I've had my Nexus 5 for roughly around a month and I hadn't experienced any issues others have had with wifi not connecting until now. My N5 will show im connected to my home wifi with full bars, but going into quick settings shows it to be orange. Suggesting there's no data transfer, I cannot use any internet based apps with wifi. I've tried some suggestions, switching my router off then on, rebooting the phone, turning some settings off in the advanced panel in wifi settings. All have failed.
I was just wondering if anyone else has this problem and if anyone has a fix to it.

So I had the unfortunate experience of having my wifi go down while on vacation and for 3 weeks I spent a good chunk of time wiping and reinstalling multiple versions from Cyanogen, Paranoid android and 4.4 - 5.1 to no avail. I just did another factory wipe today and installed the new Android 6.0
The Finger Pointing Game is OVER
Read through 30+ pages of other android users with similar experience and some people send their units back to LG and some even managed getting a new handset. There was never any hardware issues with my unit I just couldn't turn on the WiFi but after the install WiFi works? Guess next time you push a software update to our Phones CHECK YOUR SH*T google and Maybe DON'T Take 3 months to FIX your F*CK Up.
I have a similar issue. Since Lollipop my phone almost never automatically connects to my WiFi anymore. What's wrong?

[Q] Wifi issue ! (Lollipop 5.1)

Hi All,
I got the Lollipop 5.1 OTA 2 days ago and installed it - everything went smooth and the phone working fine...
But I noticed that if I reboot my router (or turn it off / on again) the Wifi don't reconnect unless I turn on the screen (the second I turn on the screen the wifi connect normally).
I didn't have this issue with Lollipop 5.0.1
P.S.
I know that this is happening because I have a led on my router telling me if any of my Wifi devices is connected or not. And to make sure I also entered the router settings to see if my phone is connected or not.
Anyone noticed that issue with the new lollipop 5.1 ?
Cheers,
I think that your problem is not switching off the router. The problem is when your phone goes to suspension (screen off) and then it drops the wifi off.
My Nexus 5 with 5.1 is doing the same

I've got some similar behaviour here, both when updated from 5.0, and with a fresh install from the factory images. When I arrive at a place with known WiFi, the phone only connects once I turned on the screen. After that, it stays connected until I move out of range and back again.
It's probably a matter of responsiveness/battery life. The more it polls for networks, the more battery it uses. It should connect, even with the screen off, within a few minutes.
That being said, I have my wifi set to always stay connected, and I've seen it not connected when I turned the screen on, then connect a couple seconds later. So, there's that. Curious how often it does that.

That's what I suspected. Sometimes, the waiting game works, but I've had my N5 lying on my desk – where it usually gets full WiFi bars – for about 40 minutes the other day, still it did not connect until I turned the screen on.
Edit: Just now, my phone disconnected from WiFi when the screen turned off, which leads me to believe that this is all caused by the WiFi sleep policy. Could it be that Google messed up something there?

My "research" has led me to believe this is the case.
Anything in terms of a workaround?
I came across those settings in the developer options (see screenshot), especially the "Always allow WiFi Roam Scans" looked promising. Been playing with them, but so far no luck.
Hi All,
exactly the same issues as yours guys are happening since I received the OTA 5.1 and installed it !
I Guess something messed up with this new update in regard of the wifi... as you mentioned.
If you come across a workaround or a confirmation from "Google" please share.
Cheers,
(With almost everyone nowadays having data ..it is difficult to notice such a behavior due to the fast wifi/data switching)
I have seen this happen as well. My battery graph will even show a missing area for WiFi indicating it turned itself on and off twice within a few hours and then stayed on after that.
Google just now released LMY47I, has anyone had a chance to see if that version fixes our problem? Once I'm off work (in about 8 hours), I'll give it a whirl and report back.

Could you please elaborate on that? I'm familiar with Tasker, but I can't think of a way of dealing with this, since I'm not sure what actually happens with the WiFi. The settings appear untouched.

I'm sorry, but my phone is now in the service center , and press that I do not remember specifically . The idea is that when you disable wifi, a time interval is forced to connect to a particular network . Look presence on the internet , here is full of instructions.

Almost all of the changes on these different builds are SIM related for specific carriers.
LMY47I was only released to LGD821 devices with SIM cards from Indian and Australian carriers
Same problem here. I am slowly losing faith in Google. Get the frickin basics going guys!!!
Back to my 5.0.1 build.
I've gone back to 5.0.1, too. Pity, except for this I was pretty happy with 5.1. Maybe 5.1.1 will actually be usable.
Do you think it can be related to Issue 163350? code.google.com/p/android/issues/detail?id=163350
I have just reported that, but I'm still trying to understand if it just happens to me or what.

I think the solution is "use vibrate mode on". Get your device to vibrate mod and test it.
I am waiting for your feedback.

Wifi connection troubles after update to 6.0

I'm not sure if this is a Nexus 5 problem or a 6.0 Marshmallow problem but the problem occurred after the update to 6.0 on both Nexus 5s for me and my wife.
There seems to be some bug with my phone while it is asleep (screen is off but phone is on). When it is in this mode, it will not stay connected to wifi. For example, when I enter an area that has wifi, my phone will not connect. It will only connect when I wake the phone. And this isn't just a matter of the phone taking a while to connect. It NEVER connects. Before the update, my phone used to make a connection with my home router before I even walked inside. Now, I can be inside for hours and the phone never connects, until I wake it up. As soon as I wake the phone, the phone makes the connection with no problem. After a few minutes of the phone being asleep, I will wake the phone and the wifi connection will be gone. Now that it is awake again, it connects again with no problem.
I have tried forgetting the network and creating a new one, I have tried different routers, I have tried wiping the cache partition. I haven't tried a full factory reset, and I'd prefer not to, but I guess I will if I have to.
Just thought I would check here first and see if anyone had other thoughts.

Thanks for the reply. Yes, that is what I thought at first also. I meant to say in my original post that my wifi settings are set to "Always On" during sleep. I've tried toggling that between the settings but still have the trouble.
Sorry, my Nex 5 has not this issue on Android 6 build MRA58K.
Alessandro
Yup, have the same issue. When the phone goes to sleep, it seems to disconnects from the wifi and never connects after I wake the phone. When I go into the wifi settings, I see "WIFI Connection Failure". I have to reconnect manually. Like the OP, have it set to always on as well. I also know it's not a router issue because I've tried this on four different routers (two linksys, one Dlink, one TPLink) All same results.
Wonder if this is a phone issue?

Google upped this to a high priority Friday morning (Nov 6). The bad news is I think there a couple different WiFi symptoms being discussed here. Most of what is being discussed is the issue being discussed here (not reconnecting when the screen is off).
No idea when this will be fixed, so I build a Tasker profile to toggle WiFi every 15 minutes when not already connected to force a reconnect. I’ve observed it getting disconnected on its own overnight. This should avoid unnecessarily using cellular data.
I’m perpetually waiting for the next release of Android to fix annoying bugs.

Thanks for the update Gary. The comment #6 describes my situation exactly. In doing some troubleshooting of my own, I find the disconnection trouble to happen less while on a 5Ghz network vs 2.5. I still have the trouble of it not connecting initially when I come into range, but I find that it is able to hold the connection while asleep.
I am also experiencing this on my Nexus 5 and also found and starred the thread above.
I just listened to 20min of streaming with Spotify to then realize that it had gone into Doze and used the mobile data!
This is more than annoying...
Maybe by disabling Doze for some specific connectivity-related system app? Anyone tried that?
Yes, I moved virtually all of the services type of apps (the ones with the green generic Android icon) to the battery not optimized list. It didn't make any difference for me.
In some ways it seems like it might be a Doze problem, and in other ways it doesn't. Doze shouldn't be affecting anything when the phone is in my pocket and I walk in the house to my WiFi. It also shouldn't be affecting anything when the phone is being charged, which is when I see frequent WiFi disconnects.
It will be real disappointing if this isn't fixed with 6.0.1.
This is still an issue with 6.0.1. Nexus 5 (2013) 6.0.1 MMB29K updated through OTA ZIP pushed with ADB.
Things work properly for a while right after a reboot and then WiFi never connects until the screen is turned on.
Google Connectivity Services C.1.6.7 (2466695) update didn’t make a difference either.
Same problem as the thread starter. HTC A9 anroid 6.0. (newest available OS)
Same problem here with a Nexus 5 .
Please star the problem if you have it.

Has anyone tested with a non-stock kernel ?
I'm asking because the problem seems +/- resolved on CM13 (non caf).
No counting CM13, do you know of a more stable rom with the problem resolved?
Does anyone here have Wemo devices? I am reading that wemos, and possibly other devices that emit their own wireless network, may cause problems. I have several of these devices around the house, and wonder if that might be contributing. However, that only would solve the dropped connection bug I have, not the failing to connect while asleep but I have.
Hi mates, my Nexus 5 (android 6.0.1,M8974A-2.0.50.2.29) gets the same troubles with wifi connection but today I tried to put some apps in non optimized list of Doze and seems workig fine.
Thats my non optimized Doze list:
-Google Play Services
-System UI
Try it and let me know if it works properly.

I had Google Play Services already set to not optimize, but hadn't tried System UI. I will try that out and see what happens.

Welp, that didn't work. Still have the error after not optimizing System UI in addition to Google Play Services.
I don't know if the issue is resolved, but at least for me, it never worked fine so many days after testing some new workaround.
So, this was what I did in my Nexus 5 (latest build, MOB30H).
Uninstall or deactivate Google Connectivity Services, reset your network settings (you will lose your Wifi networks and BT pairings), reboot.
My Nexus 5 has been connecting to the wifi networks even with the screen off for the last 6 days.

Miguun, has the error returned, or still fixed? I just got the May update, so fingers crossed that fixes it. Otherwise, I guess I'll try your fix. I don't look forward to entering the wifi network information again.
Yup, it is still working !!
