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.

does aokp have a setting like i think TW has where if the wifi signal is too weak it will use network instead?
its called avoid bad connections on cm10

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.

Weird

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.

Not receiving notifications when screen is off

Hi All,
I have a N7105 and I've just noticed that I'm not receiving any notifcations from Facebook or WhatsApp (I've only tested it on those 2 apps so far) running on data not WiFi when the screen is off.
Once I turn the screen on, the notifications still don't appear, however once I access an app or internet browser that requires data connection, then I would receive those notifications.It seems like the data is switched OFF when the screen is also off.
I've read a few posts outside of XDA and apperntly it could be a 'Jelly Bean' 4.1.1 bug?
Is anyone else experiencing this problem?
Cheers

Anyone?

Can you test it with wifi and see if it still happens?
Also can you still receive calls and sms while screen is off?
Also also, have you ever installed any battery saving application?

It's stock as a rock. I only got the fone last week. What's fast dormancy? I guess I haven't since I don't know what it is.

Which rom are you on? If you're on the newest, try getting on an older one to see if it helps.
Also have you checked your APN settings for your carrier?
Lastly, check that you do in fact get NO data as soon as the screen is off. Test all the apps, and email. Download an app from Play, and turn off the screen mid way to see if it interrupts.

Im on jelly bean 4.1.1.
I've checked my APN even reset to default even though I didnt touch it when it came out of the box from my service provider.
Most of the time I wont receuve a notification unless I turn the screen on and wait a minute or 2. However they do come through sometimes when the screen is off but theres like at least a 10-20 min delay from when the message was sent to me and the maximum time ive noticed is 1 hour.
I called Samsung and they suggest I hard reset using a code they gave me. Really frustrating and ive only had this fone for just over a week.
I don't really want to hard reset this brand new fone. But it looks like I have no choice since no 1 else is experiencing this problem.

Its a possibility but my cousin has the exact same fone and we're with the same carrier as we both got thr phones at the same time.
He's sgn2 is fine. Receives all notifications when the screen is off seamlessly. I compared both our settings and its exactly the same. Which is why I doubt that it would be a carrier fault. But I again I could be wrong.

Ok. I gave up. I ended up factory resetting the phone. Its resetting now as I type.
What is more frustrating the code: *2767*3855# to hard reset didnt even work! It came up with an error saying that it is an invalid code.
So i just went to settings then factory reset.
If this doesnt fix the problem, I will call Samsung again and ask for a replacement handset.

[Q] Possible wifi issue?

Hi,
I am wondering if it is normal that wifi speeds slow down after a certain time. My wifi at home can reach up to 22 Mbps down and say in a couple hours for example it would drop to 10 Mbps. Immediately I would restart my phone and it would be back up to normal speeds of 20ish Mbps. I do multiple back to back tests on speedtest.net app and my wired connections and other wireless devices are consistent.
My wifi does not disconnect and it has no problems connecting to other souces. At work i have the same wifi issues.
I have a Canadian Rogers Note 2. I am rooted and flashed to cleamrom 4.0.5, fully wiped and reset before flash with twrp. I have tried turning off power saving mode during the slow wifi transmissions and still have this issue,
I am lost as to what to do. Any advice would be appreciated.

Yes this is for me as well I have been on clean rom and now stock and it continues to do the same not a huge deal but I just noticed it last night im on mediacom if thats any help
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2

In the meantime I have installed My Data Manager to see if there is any unknown wifi data transmitting while this problem is happening. When I had the phone bone stock I really did not monitor this issue.

I use the international rom and I notice YouTube buffers longer than it should than it chops shortly after. I just tried recycling wifi and now it's snappy again.question now is how long it will last

Sent from my GT-N7105 using xda app-developers app

I have been playing with this issue for a few days now. I can sort of recreate this by leaving the wifi range and entering. This will create that speed drop I described in my first post. By turning on and off the wifi toggle resolves this.
While using My Data Manager it shows no mystery wifi or data transfer in the backgound. Everything checks out in that aspect.

I did not notice a drop when infront of the AP.

I'm running stock Att and started having slow wifi speed after the 4.1.2 update. Toggling the wifi fixes the issue but it slows down again eventually.

yeah this blows. I don't know where the fault is. Running cleanrom 4.0.5 with its kernal. I don't believe I have really modified anything other than flashing the rom and a few zips here or there.
Normally it isn't a big deal but it really seemed to cause issues when syncing for the first time with dropbox yesterday. I had to keep restarting wifi. I think part of that was dropbox but 4 gb took literally hours to get done
I don't know if it happens on cleanrom 4.2.5

I am on CleanROM 4.5 right now and it behaves the same way. I did read on another thread that there is a possible fix by replacing the 'wifi' folder with the one from Android 4.1.1.
Here is the whole thread http://forum.xda-developers.com/showthread.php?t=1956155&highlight=wifi+problem
I have performed the suggested fix and will monitor the issue when I go about my daily routines.

Any new info on whether your idea worked? I'm experiencing the same thing you guys are.

WiFi not working

Hey everybody!
Currently I am running the Lifeless v14 Rom on my phone and the phone will not connect to a WiFi connection. After I input the password it just goes to saved but will not connect. I have tried with multiple connections and different ROMs and it only does this on stock based ROMs. I would appreciate any help, thanks in advanced.

Kernel?

If you haven't figured this out yet, maybe this will work.
ZVB has some issues with WiFi. Turn WiFi off, reboot phone, then check to see if Wi-Fi stayed off. If it stayed off, then you should just be able to turn it on and it should work. If it turned itself back on, turn it off, reboot, and more it should work.
If you have a tethering app, that will mess with WiFi. You can only run one or the other per reboot.

I think I tried it before but I'll try it again since I reflashed. I haven't installed any apps whatsoever so I know there is nothing that should be regulating my WiFi connection. Also whenever I tap on Connection Optimizer it says "Setup has not finished yet. Please try again later." I don't know how long I need to wait, it's been a few hours now..
Scratch that, turning off the connections optimizer didn't work.

Did you ever get this sorted out? I've been having the same problem for the last week. I ended up going back to stock ZVB but it's still not working. I tried updating the radio, zeroing and reflashing my EFS but no luck.

Try the following:
1) power off device, remove sim, then turn it back on leave it for about 5min, power off, re insert sim then power it back on.
2) Call VZ tech support and see if they can swap out with another phone, just tell them you phone randomly drop signal, they will attempt to re provision your device or ask you to do factory reset and if still not working, tech support (not customer service) could over night another brand new phone to you no charge. Good luck!

Thanks , got a new phone.

Both my wife and my white note 4's appear to have signal issues. I think the crappy signal and drop calls is only happening at home (west bend, wi). I have never had this problem with US cellular and because both our phones are having this problem, I wont to believe its not the phones (or maybe it is?).
Is there a number to update the towers for Verizon? How should I go about this?
