Jellybean wifi issue

Hello,
After updating from CM9 to CM10 I started facing wifi issue. My phone works normally for 1-3 days, and then wifi stops working. If I go to wifi settings, it says "Searching for Wi-Fi Networks". Also, wifi cannot be turned off. After reboot wifi operates normally for some time until this glitch happens again.
I thought it was CM-related issue, but some people say they have faced this issue even with stock JB.
Do you have this issue? How can it be fixed?

Toggle airplane mode.

Thanks, but I'd like to know if there is a way to fix it completely Does everyone just toggles airplane mode? Is there a firmware without this issue?

No idea on how to fix it, i have it too.
It's not happening too frequently to bother me.

Is there ; Support connect to wireless network by QSS (Quick Security Setup)??
for this build patch?

I have this exact same problem on CM10. I did a full wipe and the problem remains
I will keep searching for a solution, but I really hope someone can tell us more information as to what the cause might be.

WiFi turns off when screen is off?

Hello, i'm using CyanogenMod 10.1, but i had the same problem with AOKP.
The problem is that, when i put in standby my phone for a long time, Wifi turns off (or it just disconnects, that's still not ok)...
It takes a while, i mean, if it's in standby for 5 minutes or less, everything seems ok, but after a while (don't know for sure how long), when i wake it, i find that it was disconnected. The problem is that i don't have a flat data plan so when i'm at home i have to choose if use my limited data or not receive network notifications...
Any solution?

Try turning off "Avoid Poor Connections".. and
Turn off "Wifi Optimization".

R: WiFi turns off when screen is off?
I'm trying... Does disabling wifi optimization make it a lot more battery hungry?

me too have the same problem in my xperia ray
but iam using cyanogenmod 9.1.0 stable version...
but when the screen is off for some minutes the wifi turns off even i gave keep wifi on during sleep in wifi advanced settings

I often have the same problem. I've tried fixing it with most combination of those WiFi settings, in both stock and CM10.1 and it still happens. I think it might be something with the phone, but if anyone knows of a way to fix it, that would be great.

WiFi is known issue on 4.2.2 ROM.

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.

his complaint though is that wifi is using battery when off, not when it's on. Issue below:
https://code.google.com/p/android/issues/detail?id=81188

Go in settings / wifi / advanced options and untick Network notif and Always available Search (not sure it's exactly named as it since i use french settings)
After that wait about few minutes and check wifi usage as you done before to make screenshot

so i should wait for 5.1...

well the issue is still open so i assume its not fixed lol. google it to see if they resolved it in 5.1

its still not fixed in 5.1. nor is the memory leak. God is google slow in bug fixes...

Wait.. what theme did you install to make the status bar with that color?
sorry for being off-topic but I'm curious.

Question Wi-fi is always turning off

I recently got my Fold3 and I'm loving it except for one really annoying issue: my wifi keeps turning off, 90% of the time I turn on my phone the wifi is turned off.
I have already tried disabling turn on wifi automatically and the wifi power savin mode, I have also reset the network settings and it still does it.
A couple of times today while I was trying to fix the issue I would go, turn on the wifi, then start looking at the menus just to realize that the wifi turned itself off within 10-20 seconds of me turning it on.
I have searched but apparently there is no previous threads about this.
Thanks
Vinny

This problem is very similar to the "bluetooth issue" that some users are having
Have you tried to keep your phone closed and see if wifi goes off too ?
Or is this only happening when you unfold it ?

Does it happen when you're on every Wi-Fi network or only your home network?

Maybe you should consider doing a factory reset .
Not ideal , as you will have to set it up all again , but... best way to know if its a hardware or software issue

use Nice Catch to see what is changing the settings on your phone.

do you have any bixby routines running?

That rules out a network issue then.
