[Q] Why wifi is turning off when screen turns off? - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I am using a samsung galaxy s2 I9100 phone and recently updated to Jelly Bean 4.1.2 XXLS8. My problem is that when I turn my screen off or it turns off automatically, the wifi network is off. Wifi duing sleep is turned to always on in settings but doesnt seem like working. If im chatting and until someone replies the screen turns off, I wnt receive any notifications until I turn it on to check manually. Same applies for email. When i turn the screen on, it will show wifi now connected. This was not a problem on ICS as even though the screen was off, I would receive notifications and email as it is sent.
So can u please suggest a solution and also I dont want to go back to ICS
Thanks

Thx for your reply but as i said i dnt want to downgrade from Jelly Bean as i waited long to have it and it works well. The only prob being that wifi issue. I fink this problem should be solved instead. Anyone having the same issue?

Try to use a nuke script on the device and reflash JB.
Don't forget to backup everything.

Whats a nuke script and how to do that? And also do i install the same version of JB again or search for another one as this one has a wifi problem. I downloaded it and installed via Odin.

Reflash JB just like you flashed it the first time.

Are you guys using any battery saving app? Are you using stock Rom or any custom Rom? Please provide these data along with your question. Without these it's difficult to figure out the problem for any expert.

For some days I think I will try to install stock 4.1.2 and no personal apps from Play Store or root, in order to understand if the problem is app related...

Same problem here with stock rom, no battery saver apps, and battery saving not active in the settings.
Upgraded to JB with Kies, factory reset afterwards.

Your kernel can turn the wi-fi off when the screen is off. I think it's a kernel issue.

No news about this issue? Did anyone try with XWLSN?

Finally I fixed our problem about wifi. I know you will consider me a stupid, because my solution is related to something we decide to exclude from the possible causes of our wifi issue, but... The problem is fixable managing the router settings! I have a b/g/n modem-router... When it works in b/g/n mode the wifi issue appears... If it works only in b/g mode it disappears! I had exactly the same problem with a Sony Ericsson Xperia Ray, and the solution I found for S2 works for it too... I hope this can helps you too.
Let me know if you fixed or not...
Ps: I actually am on the stock XWLSD...

Wi-Fi crashed

I'm using CM9 and strange thing happened to me. I touched the status bar widget wi-fi icon but it did't turn on. When i go to settings the ON/OFF switch is in OFF position and shaded. When i open the Wi-Fi menu it says: "Turning Wi-Fi on..".
I tried restarting the phone, turning it off and even plugging out battery but no change.
Is there a way to fix it?

I'd recommend you reflash the rom and see if the problem arises again. If yes post in discussion thread of your rom... someone may solve it

Screen Not Timing Out

Hi guys.
Am on the latest 4.0.4 unbranded in the UK (waiting patiently for JB)
But my screen is not timing out and is draining the battery something chronic, basically unplugged it from charge this morning and have just got the message for the phone to be plugged into the charger.
The display timeout is set to 15 seconds but unless I press the power button to put the screen off then it is just constantly staying on.
Help anyone?

Have you ever been able to connect in the past to the office router with the device?
If you are certain that you are inputting the correct password and are in range of the router, and trying to connect to the correct router, there is one thing you can try that worked for me.
Input the wrong password, and try to connect. It will fail but gets things moving again.
After this input the correct password and it should connect.
Good luck and I hope this helps!

I'm having the same issue. I'm running a stock ROM 4.1.2 (update received 4 days ago) and ever since I'm having this problem. My router is fine, everything else connects to it and I've checked all settings on it.
I've hard reset my phone twice since Friday and tried everything I've found (and understood). Can anyone provide a solution?
This will be the last Samsung I have as they don't seem to give a crap once they have your money.
You're having this issue since JB?
As far as I know this is not a bug, it's about settings.
Sent from the little guy
Yes. Only since the update. All settings have been checked, deleted and re-entered and it still drops out.

A re-flash won't hurt, I find it odd tho.
You can also contact your carrier and ask them about this (you had an ota/kies update right?
Sent from the little guy
It was an ota update from Samsung. I'd contact my carrier, but so far, every time I've called for something it's been an education for them!
Might try re-flashing over the weekend.

No service bug.

Hi guys!
Currently running miui and I've started having some issues. The experience is flawless expect for one little thing, I can't make calls. It used to work but has all of a sudden stopped working.
There is only silence when I attempt to make a call, however the phone I'm calling rings, but if picked up you can't hear anything. Then it would automatically hang up and say no service.
It seems like the phone isn't latching onto the network or disconnecting when I make a call at least.
Any help would be appreciated.

Sir, doesn't this sound like a problem either with the Modem or some system files (Like phone.apk) ?
Well, you are the senior.
Just a doubt actually..
It is just a possible solution, derived from similar problem on aosp, worth a try
Hey guys. Lock sounds are on. Still can't hear calls even when they connect and are picked up.
It worked when I cleared data for phone.apk but only for 2 calls and now it stopped working again..
Messages and internet work fine though.

Try re-flashing MIUI with a fresh install
Then it should work again. I'm using MIUI without a problem ( I know, I have to update my signature)

I saw both google services and updates service running in the background when wifi is on / off. No custom rom, no overclocks, tweaks or whatever. I tried v6 supercharging, cwm, root etc etc but nothing worked. On 100% stock now.
