my wifi can't automatically turn off when screen is off - T-Mobile Samsung Galaxy S II SGH-T989

HI,
I tried to set my wifi sleep policy to turn off wifi when screen is off. but it doesn't work. the battery info shows the wifi is on all the time even after a few hours. I have tried Juggernut 5.0, and latest Darkside and slickmod roms but none of them works. Does anyboday know what's wrong? thanks

Nobody can help?
Today I reinstalled darkside rom after wiping everything. then I tried again without adding any of my own apps. but wifi still can't sleep when screen is off. I am really confused.

try to change a rom, i did have that before, after i use another rom with different kernel, battery become amazing

[Q] Wi-Fi Error

Hello!
I don't know it is only me or not but after my Epic 4G with the Froyo running for a day or two without reboot, If I'm trying to turn on Wi-Fi, after half minute or longer I'm getting the message 'Error" and can't run Wi-Fi. It is working only after I'm turning my phone off and then turning it on again.
Can somebody help me with it? Maybe you have some recommendation what to do?
Thank you!

Are you using juice defender? I noticed that problem a lot when I have juice defender running.

I get this but not always. Wifi always works the first time after the phone is turned on, but after that it's about 50-50 for me whether it will come on again the next time I try vs. if I'll have to reboot the phone. I'm on Quantum 2.7 with EXT4, no juice defender/app killer/anything like that.
Unfortunately, I have no solution for you (or me), but I have found that I have a slightly better chance of getting wifi to actually turn on if I do it from the "settings" menu, rather than the status bar button.
Yes. I have a juicedfender. You think it might be the problem?
It's the DK28 rom that is the problem. The one you are running is based on the leak. I had the same problem when I installed the leaked update. Wifi would cut off sometimes and when I turn it on from the notification area it would try for a bit then say error. Going through settings to turn it on would work.
Didn't have juice defender so I'm pretty sure that isn't the prob. Soon as I switched back to DI18 never any problems.

For me with juice defender it happened very often. Without it not as much.

In no way is it Juicedefender that is causing this issue. Juicedefender simply causes the wifi to be turned on more often so you notice it more, IF you have it set that way.
This is a DK28 issue. It happened to me every day when I was running the stock DK28. It has happened to me a lot less often, actually not at all, from running custom roms based on DK28, but I have only been running those for a few days. I have not intalled juicedefender on any DK28 rom I have run, so that is why I am sure it is unrelated to that program. My only theory is that juicedefender is just making the issue more apparent by constantly toggling the wifi.
I have the same issue and I dont have juice defender. I always thought it was after I had been using 4g but I do randomly get it and have to reboot. I'm on dk28 also
On any dk28 wifi only freezes itself.never ever works. ever. No JD or anything like that installed.

If I remember correctly instead of rebooting my phone when I would get that error on dk28 I would just go into the built in task manager, go to ram management and clear out both level 1 and 2. Then if I try to turn wifi on it usually works for me.

That worked for me as well. Also if you go into settings to the Wifi settings and disable it and re-enable it in there is usually worked for me.

That fixed it for me! Will I receive the official release if I installed the leaked 2.2 a few months ago?
Anyone has found a fix for this issue? I'm still getting it on EB13. Is there any utility included in Busybox (or custom) that we can reset the device manually?

I'm on EC05 and still have this problem. It seems that after several on/off cycles of the wifi it starts to do this. Rebooting solves it. Haven't tried the level 2 memory clearing. I'm running juice defender and a location-based app that toggles wifi on and off for me. Between the two, wifi gets toggles a lot.
I'm running EC05 stock, rooted.

[Q] Phone barely sleeps when Wifi is on. Baffled.

So after quite a while debugging wake lock issues I finally figured out what was causing my phone not to sleep. Wifi!
I'm on MIUI with Savaged Zen 0.0.5 (happens across kernels) latest radio/wifi/wimax downgraded to 1.77 PRI/NV. Running MIUI, so wifi sleep policy is set to never to prevent random reboots.
It's very easy for me to duplicate this, when I have 3G on my screen on vs running time are nearly equal. If I turn off the display and leave wifi on my running time will be 300% of my screen on. The only "solution" i've come up with is to turn wifi off on display off with Tasker, but I thought wifi should be a more effecient radio than 3G, generally i've heard you get better battery life while on wifi....
The only thing that I can think that might have caused this is I imported my Wireless AP stored settings from a sense rom when moving to MIUI using Ti Backup. I'm at a loss on how to fix this though -- is there some sort of cache or something I can clear to get wifi back working correctly?

No problems here with 0.0.5
My phone sleeps fine on both miui and salvage gb. Not sure why its giving your problems... i would have to guess its an app or something you have installed. Ive had two different miui installs and they both were 100% fine.
I'm not blaming the kernel or MIUI, I just have no clue how to debug this. I have a very minimal app set up now, i've uninstalled nearly everything...I would think if it was a rogue app it would happen over 3G as well as wifi...that's why I think it's something wit the wifi service itself, I just don't have any idea how to clear the wifi stuff off there's no data cache or anything.

Wi-Fi turns off when phone in deep sleep

Hi, I saw many posts related to this topic Wi-Fi turns off when phone in deep sleep but not able to find a single working solution.
My phone runs on 4.2.1 with wi-fi sleep policy set to NEVER ( that means always on ideally ) , and tried turning on / off wifi optimization, avoid poor connections is not ticked.
Even after doing everything the wifi is turned off after sometime and when i turn on Screen it turns it back! How to do I solve this?? I am using STOCK rom, with just root.. No other battery saver etc. app installed.

well i have this problem too on every jelly bean rom. the only rom without this problem in cm10 stable. now i'm with cm10.1 hoping they'll fix it like in cm10.
when that problem comes out just toggle on and off airplane mode and it should disappear until next wifi toggle off and on.
I hope google will solve it in key lime pie
CM 10.1 has only just started doing this in the last week or so, it was fine before. Was wondering if it was just me with this issue or not...

Am i correct in understanding that you don't want it to disconnect? The option in the settings is "Keep wifi on during sleep". If you have it at Never, then it will disconnect when the phone goes into sleep. It should be placed on Always because you want it to be on even during sleep
Flowed and Tapped from my Nexus
fixed the wifi problem
Heya! My first post!!!
So, i had the same problem on my Allview P5 Quad.
The guys from Allview released an update for my phone based on 4.2.1 and i thought the problem was from them. I had WiFi turned on and after a few minutes from entering sleep mode, the WiFi got disconnected, both WiFi and data. I have installed the last update again and again, rooted, unrooted, tried every option from WiFi and i still had the same problem.
So i timed the time when the WiFi disconnects and it was exactly 6 minutes. So i thought that it must be an option that does this. So i unchecked the Quick Power Saving icon from Switches and ... SURPRISE! My WiFi stays on continuously. So, the problem is from the system power saving settings. I hope this helps all of you.
P.S. Love this forum! Thanks for all your help!
I believe I found the problem, some how it is not the phone but my wifi router (and all routers) is the problem. Go into your router settings and look for the "Beacon Interval" and set that number to 50. I'm not going to explain what the beacon interval is, go google it and you will see. I switched mine and now the wifi on my phone does not switch off when in deep sleep.

Wifi Keeps Stalling

I have had a problem for a while now where my wifi stalls. When I wake the phone the wifi will work perfect for a few minutes. Then it stalls and just sits there for a minute or two and then kicks back in but then stalls again after a few minutes. If I turn wifi off then Internet works flawlessly. Also when it stalls if I turn wifi off and back on then it works again.
Right now I have bountyman's lollipop rom on an AT&T E980 installed but it has done it with several other roms as well. I have tried flashing different versions of the modem but there is no change. It is really getting annoying. Has anybody else had this problem and if so how did you fix it?
Make sure that u r not running the battery save option as it will keep turning off the wifi when.it is not in use....

Thanks!!!! That did the trick! Wifi is perfect now. Pretty lame feature cause according to it's settings it's not suppose to do anything until the battery gets down to 10%. But apparently it is still doing stuff even if the battery is at 100%.
Thats good news
U r welcome....

WiFi crashes after phone goes to sleep

Hello,
I have recently factory reset my OP3 due to a battery drainage issue. Google play services started using around 30% of my battery and consequently my SOT decreased by a lot.
After the factory reset, I freshly installed of all my old apps, and I downloaded my photos from the Gdrive.
Unfortunately, since then my WiFi is acting strange. Whenever I start the phone, the WiFi is performing normal, but after a while my phone goes into deep sleep and my WiFi disables itself (just like i configuered in settings). However, when I wake my phone, my WiFi won't turn on and when I go to the WiFi settings the phone becomes extremely laggy.
I have already wiped my cache again but I don't know what else to do.
Any help is appreciated!
Kind Regards,
Same strange problem here,I must reboot phone to connect wifi.
I trying with 3 kernel, it's not kernel problem.
It's such a strange problem. I don't understand why this problemwould occur after a complete factory reset...
I had the same issue a few years ago with my HTC One M7.
By the way, my OP3 is completely stock running Android 8.0
Same problem with my 5T on 5.1.1. Weird thing is I haven't made any changes, just updated a few apps but none of them should be causing wifi issues and settings (battery history) to lag after sleep.

I have set wifi to always on and don't have this problem. May be the doze feature is affecting it in your case. Why don't you try the always on setting? For me it doesn't drain the battery also. So no harm in trying it.
And why settings not responding? I must touch home button in order to have working settings again.
I think it's Oxygen Os problem.

The problem does not occur if I set WiFi to always on. However, this uses way more battery in my case.
If i set WiFi to always on my sot decreases from 4-5 hours to 3-4 hours.
EDIT:
I also can't find this issue anywhere else on the internet.

Can't find anything either. You have any of these apps installed? Substratum, Microsoft Remote Desktop, Twitch. Updated these apps two days ago which is when I noticed this problem, haven't change anything else really. Updated router firmware too (Virgin Media).

I can only think of factory resetting again and checking the behaviour of wifi before installing any other apps and downloading photos. Then you will know whether an app or the downloading is the cause and take action accordingly.

No, I haven't installed any of those apps. However, since the factory reset I started using the regular Chrome instead of Chrome Beta.

I could also test that with the phone in safe mode, right?

I think so, yes.
I just disabled all third party apps, and the problem still persists
I have set wifi always on,and flash HolyDragon kernel, problem it's gone.
I don't know if kernel, or settings always on wifi, resolve my wifi connection.
I've been having the same problem too as of yesterday. Did a factory wipe and reinstalled Oxygen 5.0.1 but still having the issue after i reinstalled apps. going to try a factory reset again and not install or update any apps to see if maybe a recent app update is causing this.

IT didn't work for me. Right after flashing the OS back onto the phone and connecting to WiFi, i changed the WiFi setting for "Keep WiFi awake when asleep" to "only when plugged in" and after locking the screen and waking it back up a few minutes later it still wouldn't activate the WiFi; I had to manually go into the WiFi settings and turn WiFi back on.
On the bright side though, I did do some reading on the "Keep WiFi awake when asleep" setting and several sources said to leave it on "Always" since it actually drains more power turning on the WiFi radio when the phone wakes up. I've since changed that setting to Always and over the last two days I've noticed slightly less battery drain!
It happen to me too. Cant turn on wifi after waking up from deepsleep. Must reboot the phone. I had tried to clean everything , data, system,cache, everything and made a clean flash but it still happen ,only for 8.x android. I tried in Nougat and see no such problem. Im using oneplus 5t
Yea, I have same problem staring with oreo update. Can say, that I tried all kernels around, and some of them made wifi connecting faster or even reduced the number of crashes, but not completely. Sadly, I can't stay on those kernels, coz I have another problem, - iv got random reboots with most of them, only stock works... So every solution is inappropriate for me, and I reverted to nougat waiting for Android 8.1
Same problem here. I am on beta 35. Additionally I was on Franco kernel and had random reboots. Kernel back to stock no more reboots but still the wifi issue. I'll test the always on.
Hopefully it gets fixed in the next update. For now, I'm using the ''always on'' WiFi option.
Thank you all for the replies!
