data hanging

Hi,
Does anyone have this problem on their phone? Every now and then, when I am doing a data related function, data hangs as though it is not connected even though I am in a perfect 4g coverage area and the 4g sysmbol is still on. I know its hanging because the arrow to the right of the 4g symbol stays lit green. It either starts working 5 minutes later on its own or I turn wifi on and off. I have the newest sim card installed.
Any thoughts?
Thanks

probably a software related issue
the only time i experience that is when i lose connectivity with the network, as in the signal bars or 3G/4G arrows are all greyed

Yea dude i noticed even tho i have wifi set to never it always shuts off or i should say loses connection i hate it because i have to pull down status bar hit it off then on wifi is definitely effed on stock too. Anyone else experiencing this? I know its a problem cuz my g2x i could leave it alobe for an hour in hibernate come back and wifi still good to go anyone have any ideas? Or is it a s2 problem witg wifi cutting off. Like i said the icon will still be there but i wont have connection and 50% of the time i have wifi icon and 4g

Same issue here, in two different phones I've had. Not sure what the issue is. In fact, opening this page, my data was hanging for a minute, irony.

for this issue you can configure how WiFi behaves, but the settings are only accessible via spareparts or custom ROMs
I set my wifi to never sleep while on charger

But this happens to me when my wifi is off. Only on the cellar data connection.

I had this issue after giving juice defender superuser permissions. It seemed that it would not turn data back on when I had the screen on. I'm not sure if this applies to you, but I no longer gave juice defender su and everything was fine. a lot of those functions in that app do not seem to play nicely with this phone yet anyway.

Yep, for several weeks now. I thought it was my ROM.

It happens to me several times a day. Usually right after a voice call. I just put on flight mode for a second, switch it off and data is back. I have no idea what's causing this. Always on 4g, wifi is working perfectly.

+1 to everything already mentioned.
I was in Vegas this weekend and had HORRIBLY slow/no data at all. Like has been mentioned, the green arrow with just stay lit. thought i was the rom, i nandroided back to stock, same issue. Hope this is fixed soon it is hella annoying.

This fixed it for me
I have had this same issue for a while, here's how to fix it. Go to Titanium backup, I found out that there're two versions of "My account" on the list, so I frozed the old one, then go to task manager "kill all", the 4G icon will disappear. Open up "My account" again, the 4G reappears but as soon as I close the app, the 4G icon would disappear.
Hope it helps someone

I too have similar problems where my data hangs or doesnt want to connect. Then a few minutes later, it will decide to start working. This happens even in full signal regions. Stock rom and/or BeastMod rom...
Not sure why it happens :S

For those having problems and have tmobile my account on phone freeze it or uninstall it i guarantee it fixes your data problems trust me. I to had problems just like you guys and i was told to uninstall my account i was like what? What the hell is that going to do but believe me when i say it worked! I actually unfroze it to see if the problem would come back (4g and wifi on at same time) or cutting out. And it did. So i refroze my account and bam 4g disapeared while wifi on. This has fixed all my wifi and data problem phone works flawless now! Basically i think t-mobile trying to snoop with our data. Scumbags

This is happening to me. The phone is driving me mad. It happens constantly. The "up arrow" in the 4g icon will light up, and all data will freeze. I stare at loading screens all day long. It freezes anywhere from 30 seconds to 2 minutes. Then it will fix itself, then it will happen again within 2-5 minutes. I'm furious with this phone.
Wifi works great. It's not dependent on my location, it happens no matter where I am. Doesn't matter what I do, nothing prevents it from happening. Of course, the Airplane mode toggle or resetting APNs and all that will do the trick to fix it temporarily, but it will only happen again 5 minutes later.
I'm on stock, unrooted. I am ready to throw this phone at the wall. Has anybody else managed to actually fix it or get a response from Samsung/T-Mobile?

I should have read this thread before buying this phone. This is so annoying. I tried to put the phone in flight mode. It fixed for a min and back to problem.

I'm having the same problem. I didn't have this problem until I updated to 2.3.6. Anyone else still on an earlier version?

Same things been happening to me lately, its awfully annoying. Makes me want to throw my phone across the room sometimes.

[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?

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. :/

Anyone else having WiFi issues on CM10 nightlies?

I have a gsm Nexus and I'm running the Aug21 nightly, but I've had this issue for awhile, at least 2 or 3 nightlies. I'm not sure how long because I was on vacation in a WiFi free zone all of last week.
My WiFi can't find any networks but can't turn off. It perpetually says 'searching for networks' but never finds any. If I try to switch it off, the switch hangs on Off with a darker shade of grey for a few seconds then flips back to On.
If I reboot the phone, everything is fine for a few hours. WiFi can turn on and off and doesn't seem to have any connection issues.
My battery life doesn't seem to be suffering all that much, so it seems that WiFi is sleeping normally.
I haven't any logs because it's hard to pinpoint the exact moment when things go wrong.
I haven't tried wiping yet, but I'll give it a try if no one has any other advice.
Is anyone else having this?

Did you figure out how to fix the problem? I'm experiencing the exact same problem.

I wound up doing a factory reset and installing CM again. If that doesn't work, format /system and wipe data before flashing. It comes back every once in awhile. I have no idea what caused it, but a reset'll fix damn near anything. I had an issue where my phone thought it was charging even when it wasn't plugged in and had to return it to get a new logic board, I might've just had a lemon. Have you had any other hardware issues?

I had this issue for a while too. After I did a full wipe and went to the latest nightly it stopped happening. Also I turned on the 'always keep wifi on during sleep' option in settings.

I get it too. It's random, and it is not fixed by changing the kernel. Very frustrating.

[Q] Serious Issue With WiFi Hotspot

Ok, this is a HUGE issue. And if I can't fix it I will have to return the phone.
My Mobile Hotspot only works with the screen on. Every time the screen turns off I lose my connection. The hotspot doesn't turn off it just stops functioning. It works fine as soon as I turn the screen back on.
This is REALLY annoying as I use my hotspot all the time. I'm on Verizon and blow thru over 20gigs of data per month.
Can anyone please help me fix this? Is it happening to anyone else?
Thnx!

A shot in the dark and I do not have an M8 right now to confirm, but did you try enabling the "Keep Wi-Fi on during sleep" option in Wifi->Advanced menu?

If you are using power saver that has option "Data connection - Put to sleep when screen is off"

WiFi is turned off when the hotspot is active so. Not sure how that would help.
I don't have Power Save on my Verizon M8.
Is no one else experiencing this?

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.
