Wifi pauses when screen turns off

This is so annoying when downloading large files because the screen just stay on, if you turn it off the file won't continue to download.has anyone found a fix for this. I feel bad for the people who stream music over wifi, this is a big problem . I also tried dolphin browser but the browser isn't the issue

Seriously? Like, seriously guys? Hehehe
That won't fix the problem that OP is having. Search for what was mentioned, there is something coded by default that causes WiFi to basically get choked down to almost nothing when the phone is sleeping. It stays on, but the speeds go to ****.

Thank you for contributing instead of just condescending.
My first response is always the obvious fix, especially when something simple like streaming music over wifi is cited... You'd be surprised how many problems are fixed like that.
However I still haven't experienced that problem, but the OP wasn't specific enough to start eliminating possibilities and jump to a bug as the reason

I am also having this issue, Verizon GN.
Reading that linked thread a little earlier, it does seem to indicate that the new setting "WIFI PERFORMANCE FULL/HIGH" is not properly modified by apps, be they winamp or tune in (the two I have tried).
As a result, I too was getting drop outs at the time my device went to sleep. Most often the radio would pick up again after 10 seconds and continue to operate normally, but sometimes there would just be CONSTANT buffering/drop outs - noticed this more with tune in radio (tried various stations).
I am trying out the 'wifi high performance' app also linked earlier. Knock on wood, it seems to helping so far. I do have a question about it, the app (1x1) square just pulls up a screen with a checkbox for the wireless network correct? There is also a widget (2x2) which doesnt seem to ever show up on your home/main screens even though you manually put it there however many times.
Seems like the widget is not working, when pinging im getting atrocious times and still getting the drop offs... thought it might have been fixed but now trying in tune app and having constant issues.
Is there any solution? This means I cant stream radio over wifi ever??? WTH

ive never experienced this. ive downloaded roms while its asleep. radio streaming no problem. im on the sprint gnex....

Guys, see this topic and thread about the widget not staying on the screen, and about the size issue.

This is the other thread. I have been chronicling my progress. The wifi max performance app is currently helping, but does seem to turn itself off on the reg.
Will keep the other thread updated.

WiFi turns off by itself

Got my sgs3 Sunday and when I got home turned on WiFi and started playing with it I notice that I lose network for a second after about 15 mins and my WiFi icon on the status bar disappear but network comes back on .. but in settings it is greyed out and I can't turn it off then back on till I reboot 0_o...thought maybe after I rooted and flash AOKP it would be fixed but no! I'm on T-Mobile and AOKP..so is it a bad WiFi driver or...? Any ideas?

#*0011# press the menu key. Select wifi. uncheck wifi power saver mode. Its should be green when on black off. Make sure its not on and done go back to home screen. Your phone should reboot the wifi driver and your done.
This method works for 4.0.4 any of the roms. Cm10 doesn't work. Cm9 haven't tried but I'm sure it'll work for u.
Hit the thanks if I've helped!

JB has these wifi issues I was expiriencing the same problems on cm10 as well. (I know not the same but both are jb) I decided to downgrade to the intrigue rom r3. It has smooth transitions. Real buttery and it let me access the wifi power saver mode by down ng the method above. I'll look into aokp and see if I can find a fix for u.

For anyone who has already turned off WiFi PSM, is anyone experiencing this setting turning itself back on? I have turned it off twice today and every so often it turns back on which ends up turning my WiFi back off...

Question: are you rebooting your phone when this happens?
Cuz if you are that's normal on every reboot you have to go back and turn it off again.

I was not rebooting the phone. I am currently trying a different rom to see if that solves anything.

Well it still keeps happening. I switched from intrigue rom to freegs3. I'm currently using the phone at work and it happened right before my eyes while using Tapatalk... I had to turn off power saver mode yet again
Sent from my SGH-T999 using Tapatalk 2

would the method above work for me? since yesterday, my wifi kept turning on by itself. After I turned the wifi off for like a couple minutes then it'll turn on automatically again. I have the Keep Wifi on during sleep set as "only when plugged in" and it never happen to be before until yesterday. My power saving in the setting menu has always been off too. Please help! :crying::crying:

Install the app called "Wifi Fixer" app to the solve the issue.

Whatever Google did to cause a variety of wakelock problems, having a strong wifi signal seems to solve them. Apparently, wakelocks occur when there are unreliable connections to Google's servers.

Sporadically losing data

Is anyone else having the issue of data cutting in and Out? If I reboot the phone data works fine for a while.

I've experienced this also mostly when driving around town, lte is pretty new in Denver so I think it's a problem switching from lte to hspa and vise versa. Resetting seems to do the trick for me to tho

I've had this happen to me several times. Fixed it a couple of times by toggling airplane mode, but had to reboot once to fix it... frustrating.

Check that.

I found something saying AT&T Smart Wi-Fi was the problem.. I disabled that and haven't had a single issue since. I started noticing the issue after a recent update, and I think AT&T Smart Wi-Fi was pushed during that.

I dont have that installed. Debloated with tb

That's weird. I'm on stock ROM and just started noticing that. I'm probably not much help, I'm a recent convert to Android. What is TB? Do you have to be rooted for TB?

Titanium backup. Yes root required to debloat

[Q] disable cellular radio

I'm going to be in a GSM country for a while, and I'm bringing my SIII cuz it's a capable little tablet computer. I wish to disable the cellular radio completely because there aren't going to be any CDMA signals around and it'll kill the battery looking at full power (I'd think).
Is there a way to disable cellular while leaving the wifi antenna up? I imagined it'd be simple, but I'm finding it hard to even search for. Usually people just want to disable the mobile data and leave voice up for sms or whatever.

What about Airplane Mode?

I would assume he still wants to connect to Wifi.
I haven't heard of any Mods or settings that completely turn off the radio (data and phone/text). I'll keep my eyes open, though.

Turn on Airplane Mode which shuts off everything, then turn on the Wifi by itself. Used it in Europe that way without a problem.

Ah, I didn't know this worked. Back on my old Evo, once airplane mode was on, Wifi couldn't be turned on. It looks like they've improved the airplane mode functionality in the last 2-3 years.

[Q]wifi dropping

I Can't find a thread about this, so I was go ogling and that doesn't really help. I am having major problems with my wifi it keeps dropping non stop and it's really annoying. I have my phone stock but rooted and was wondering is there any way to fix this? I know it's a Samsung problem but if I were to load this up with a rom should that help? Thanks in advance

Maybe it's your router or better yet the router settings. Have you tried changing any of those settings?

Am I missing something? How is it a Samsung thing? What kind of router do you have?

After looking all night I found a thread that fixed this. You have two choices really to fix or buy your router which I'm not going to do, or you can type in on your dial pad *#0011#. Then you click your menu button, click on the wifi option, and then disable the energy saver wifi mode. That made it so my phone wouldn't drop wifi connection anymore. NOTE: each time you restart your phone you need to turn the wifi energy saver off through the command *#0011#. Hope I helped some of you because this bug is truly annoying.

That stinks. I don't have any problem and I think this is only the 2nd time I've seen anything posted like this about the S4 (the S3 did have that issue and was common). I've never turned off any energy saver and mine stays connected 100% of the time. So you're saying either that or you have to buy a new router? What kind do you have now and what settings on it did you find out that cause this issue for you?

Right now I have whatever Verizon gives fios customers. It works perfectly for all my phones, tablets, and computer. Just not on my s4 unless I do the dial pad trick. I'll post a link on the xda thread when I get home on how to fix your router. It really does make me angry that I paid 600 for the phone and it does this. Hopefully Samsung fixes this soon since they acknowledge the problem

Do you have a dlink router?
GS4

My gf has an S4 and has the same problem. We have a Netgear WNDR3500. So it's not isolated to a D-Link. She also did the dial pad trick and it seems to work for her as well. Need to find a script to run on boot to set the power save to OFF.
