[Q] wifi turns off and on when screen is off - EVO 4G Q&A, Help & Troubleshooting

In the wifi settings>advanced, I have the wifi set to never sleep, however when I am playing music over the wifi connection, the music starts and stops about every 2 seconds when the screen goes off. Is there a way to make the wifi stay on when the screen goes dark?

I am NO Android Dev but I did run into that same problem that you seem to have with running Cyanogenmod. I did searching around for a week or so and really didn't find anything in particular about the problem.
I do recommend you try, re-flashing the Rom after you do a Nandroid Backup. If you don't want to go that far you can try to set the Wifi to a static I.P. by going to Wifi advanced settings. That was my problem, but there could also be other variables that could be causing your problem.
Let me know if I helped, and respectfully hit that Thanks button if I did anything for you. Good Luck!

Was it the reflashing or the setting the wifi to a static IP that solved your problem?
The only problem with setting my wifi to static would be that it would only work while I was at home. If I am elsewhere where I can't control the router, that probably won't work.
Are any of you using Cyanogenmod as well, or does this issue exist on the stock rom as well?

[Q] Wifi dropping after phone sleeps for a bit.

My phone seems to not be able to keep wifi connectivity on CM6. It does on Sky Raider however. I tried to enable never sleep in advanced options but it doesn't seem to stick.
I've tried the wifi keep awake app. I was wondering if there was any way to manually set it with something ADB related.
I have the same problem. What I did was just turn the screen to not time out. But I would think there should be another way to where the screen could be off. Hopefully someone will have a suggestion
Sent from my Incredible using XDA App
check in the wifi settings.........menu >advanced.......you can set the wifi to go off for 3 different settings.
I've tried that, it doesn't seem to stick on CM6.

Wifi shuts on and off?

So usually my wifi keeps turning off or on and its set toggled on and idk what's wrong... I fixed permissions already but its still doing it

Yes, i have noticed this on mine at work. Will see if it does the same thing at home.
interesting problem can more people confirm?
maybe this is related to this other case? http://forum.xda-developers.com/showthread.php?t=1313800
My guess is it needs to toggle so you can recieve calls. When we get Wi Fi calling then it will be fixed.

yup, mine does this as well. just got it a few days ago. seems like when the screen turns off, the wifi turns off with it. every time I unlock the phone, I see the wifi icon come on and connect automatically. and YES, I have checked the wifi sleep options. wifi is set to NEVER turn off.
Also it sometimes completely disconnects from my router and I have to turn wifi off and on again to reconnect.
hopefully this gets resolved with the next update.
concering the issue if you look in your wifi settings and you see it scanning every 2-3 seconds, would this fix it? i remember a developer had made this adjustment to the buildprop when i owned an optimus V.
Changed wifi supplicant scan interval to 60

[FIX] Dropping WIFI (disconnect/reconnect issues)? Check this thread.

I know I had a problem with WIFI dropping every few minutes and disconnecting/reconnecting all the time. Causing streaming issues, internet issues and freeze issues if on lockscreen. Well, I have fixed this for myself and wanted to share.
To insure this doesn't happen, just follow these steps:
1. Dial *#0011#
2. Hit the left menu softkey to bring up the menu, and select 'Wifi'
3. Turn OFF the 'Wifi Power Saving'
4. Exit, and Reboot.
Ever since then, I haven't had issues. I am on AT&T GS3. If you are having this issue, please report back here with your model and if this fix worked.
Just trying to help. Good day all!
I'm not entirely certain this was happening, but had noticed some oddities. Not as bad as your experience, however.
But I did make the change to see how it would affect battery life. I am on the Sprint network.

Didnt notice a difference and after a reboot it turns back on.

I don't have issues at home but I do with the WiFi at work so I'll try it tomorrow and let you know how it works out. It disconnects and reconnects every 5 seconds and I'm not exaggerating either.
I think the WAP may be a little wonky but my HTC Desire HD had no problem with it.
Mine turned back on after reboot as well.

I am working through logcats as well. I reverted the setting to mimic the problem, and I am going to look at logcats.
If I can see what is exactly triggering it, I will make a flashable fix.
In the meantime, I have another S3 here that I have the power save off on and I still haven't seen a drop yet. So preliminary, I think this is a temporary fix until I can find out root problem.
Hope you find a fix

I have a similar problem. Mine doesn't disconnect per-se, however I did notice while browsing through Flipboard that I wasn't getting any signal sometimes when trying to access a page with a lot of content. Page loading came to a stop. Backed out several times and retried until I finally gave up. This was on my home wifi. I'll try your work-around for a few days. T-Mobile version.
EDIT: This may be just a FlipBoard quirk.
I will try this when I get home. I have a problem on my Sprint SGS3 where it stays connected to wifi but the internet won't actually work (can't browse internet, use play store or youtube, etc). Wifi never sleeps, it's always on. It never disconnects from the network, it just stops receiving and sending data. So we'll see if this does anything for it.
you guys dont have an issue where the display doesnt timeout after turning off the power save?
display won't time out from turning off the wifi power save. Totally unrelated. I am trying to mimic the problem right now.
If anyone is having the issues of the reconnnecting every few seconds and can logcat it for me, PM me please. I can't seem to mimic the problem since the fix.

It happens randomly and especially after the phone goes into deep sleep with wifi on

Turning off power save does indeed fix the WiFi issue at work. As posted before, restarting the phone turns power save back on and the problem is back.

PM sent.
Going through multiple logcats now.
I am seeing even with power saving on though, the problem is still there. It is still disconnecting from WIFI and going back to the data network.
I am sifting through ALOT of code, as some of these log cats are extremely long.
Give me til tonight and I should have a reason at least to why it's doing it by comparing on vs off on powersave.
I have a request, anyone WITHOUT this issue, can you send me a logcat with your WIFI turned on?

How do i get a logcat?

Search the forum for logcat help. I am on the phone at work or I'd link you

Thanks for this. I was about to return the phone because I kept losing ability to connect to any WAPs after sleep mode kicked in. Mine is a Verizon S3.
I've seen this as well. Almost always after deep sleep. Most of the time I have to cycle Wifi to get it connected again every so once in awhile it will connect again on its own. Regardless of the settings that I put in "advanced" under wifi it will do this. Even if I have it set to keep alive never, always or plugged in it doesn't matter.
I still need a logcat from someone NOT having these issues.
Right now from looking through over 10 logcats, I am seeing that it's usually happening on routers that are encrypted with WEP and WPA, unfortunately the 2 most popular forms of wireless security.
That being said, users that are on 'open' networks do not seem to be losing access.
2 things.
1. Can someone PM me a logcat of them successfully connecting to wifi and NOT having drops. I don't care how long the logcat is.
2. When you post about your problems, please tell me what carrier and what type of encryption is being used on the router (if any)
I have been comparing and in each instance, WIFI is going into sleep, turning on data, and then having a problem turning back on.
I think it's an attempt to save power, but only it is not because switching from WIFI to data back to WIFI so much is a real drainer.
Still working on maybe disabling the power save by using a init.d script, to prevent power save mode from coming back on when rebooted, because I know alot of users are saying after disabling it, it is just reapplying on reboot.
BACK TO LOGCATS FOR ME. :/

Welcome to the club, mate! For me, wifi has almost never worked as it should.
Mostly, it works just fine until the phone goes to sleep for a few minutes. Then
the speed is reduced to around 1-2 Mbit/s, & the only way to restore the speed
is to turn wifi off & then turn it on again. After doing that, everything's Hunky Dory
until the phone goes to sleep again. Then the story repeats itself....
I've almost given up on Samsung by now, since they seem totally unable (unwilling?)
to fix this widely experienced issue. Also, their update scheme for this "flag ship" (?)
suck big time, at least for us wanting the "NEE" version of KK4.4.2....
And btw, this phone also seems unable to record both sides of a conversation
when using a BT headset. That's NOT ok in 2014, Sammy! You've got my
money once, but you've made sure that I won't do the same mistake twice.

Has anybody found a solution to this, I can't download anything in sleep mode, tried all wifi settings, is it just 4.4.2?
Hi , is not the best solution but you can try Juice defender to automatically turn wifi on when phone wakes.
I'm on dr Ketan V14 rom and wifi works fine.
I hope that can help you.
I realize that this is an old thread.... amazing how they just peter out with no real solution.
N7100, stock ROM, Rooted, and have Xposed Deep deep wifi sleep activated.
This happens about 90% of the time coming out of sleep, even the wifi quick setting is un-illuminated so have to turn it back on. When phone is shut down and then restarted, it happens 100% of the time, even after a full re-install of the ROM, 4.4.2.
I've stopped worrying about it.

Severe WiFi Issues

In short I have the problem in said video:
https://www.youtube.com/watch?v=uTylW2ElNzo
WIFI is sporadic and connects but after screen goes off it can mess up again, and restarting sometimes does not fix it. Is there a way to resolve it? I disabled Power Save, Wifi Direct & Scanning. But wifi wants to go on & off option-wise by itself still.
Do you have an custom kernel or something like that? I'm on the road since then I can't watch the youtube link right now.

I do. However it was happening stock (seller mentioned it sometimes had wifi issues but....never said this bad)
Do you have synapse or anything similar installed? Maybe there's an configuration option to fix it. I'm beginner by myself so im not totally sure but I think I had an custom kernel which came with synapse where I've been able to change wifi settings
