Still happening

I've actually been having a similar issue recently; WiFi would be working then all of a sudden it would stop and I would have to disable and re-enable to get it working again.
It seems to have start happening after I changed my WiFi AP but other devices (PCs, laptops) are fine. I've not investigated it too much though.

So your sleep policy is set to never? What ROM/radio do you use?

I noticed this on my phone as well. I think, for me anyway, it might be down to using setcpu and underclocking my phone to slowly when screen is off, then again, I may be talking utter rubbish!

Any fix for this yet? So annoying and my only gripe with the phone

Hi,
I have a similar issue on my HTC Desire GSM on which one I have installed cyanogenmod 7.2.
The sleeping policy is set to "Never" and unfortunately, the downloads stop when the phone goes in standby mode.
(I notice this beahaviour especially with the Listen google app, that I use to manage podcasts).
I need to switch off the wifi and re-enable it, annoying!
Any idea? fix? Thanks for your help!

Yes, i have noticed this on mine at work. Will see if it does the same thing at home.

interesting problem can more people confirm?
maybe this is related to this other case? http://forum.xda-developers.com/showthread.php?t=1313800

My guess is it needs to toggle so you can recieve calls. When we get Wi Fi calling then it will be fixed.

yup, mine does this as well. just got it a few days ago. seems like when the screen turns off, the wifi turns off with it. every time I unlock the phone, I see the wifi icon come on and connect automatically. and YES, I have checked the wifi sleep options. wifi is set to NEVER turn off.
Also it sometimes completely disconnects from my router and I have to turn wifi off and on again to reconnect.
hopefully this gets resolved with the next update.

concering the issue if you look in your wifi settings and you see it scanning every 2-3 seconds, would this fix it? i remember a developer had made this adjustment to the buildprop when i owned an optimus V.
Changed wifi supplicant scan interval to 60

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.

Galaxy Nexus Wi-Fi Goes to Sleep even when always on is checked in the menu options.

Did anybody notice their WiFi going to sleep even when I have "always" checked in the "Keep WiFi on during sleep" advanced menu option for WiFi? I'm using Groove IP as my voip connection and need my WiFi to be on constantly in order to receive calls, however, whenever the phone goes to sleep mode, my WiFi connection turns off and when I wake the phone it takes a couple of seconds for WiFi to turn back on and then my voip app signs back in.
Does anyone have a suggestion for this issue?
P.S. I have a GSM unlocked version of Galaxy Nexus
Thanks

I have the exact same issue and it's driving me nuts. First I thought it's because I'm using a custom ROM, now I restored everything to stock 4.01 and I still get the same issue.
Could rooting be the cause?

It happens to me to when I'm streaming videos from phone to my tv, as soon as screen goes off on the phone within a few mins the wifi will go off or slow down considerably.

Strange wifi problem after kitkat upgrade?

After upgraded to kitkat, I noticed wifi icon at status bar will be missing after many days. Wifi will indicates as off and it couldn't be turned on. YET wifi is working fine. The only way to clear is to reboot. Anyone seen this?

I have the issue too. Anyone have any idea how to fix? Thanks.

I noticed the same thing too. Turning airplane mode on and off fixes it for me. I just got the tablet a few days ago, so I havent done much testing, but do you guys have " turn wifi off during sleep" setting on in the advanced wifi menu? I was suspecting that to be the culprit.

I realized this thread is nearly a year old, but I just bought this (used) Note tablet, and experienced the exact symptoms as described by the other posters. The wifi issue happens almost every time my tablet sleeps for more than a hour. Toggling airplane mode on/off fixes the issue, only temporarily, until the next sleep. I am wondering if there are any clues to what causes the issue.
Is it a bug in the factory rom, or something that I installed?
Here is the info of my tablet:
- US model SM-P600 (XAR), with latest stock rom UEUCOB1
- Rooted by TWRP 2.8.5.1
- Xposed installed with these modules:
Wanam
No Wake of Charge for S5, and
App Settings (only change rotation setting for one 3rd party app).
I am considering do a factory reset and setting it up again from scratch. But I want to hear if others are experiencing this issue even with 100% stock (non-rooted) rom. By the way, the issue only happens when you set Keep Wi-Fi on during sleep to either "Never" or "Only when plugged in". I would really appreciate someone with non-rooted rom letting me know if this happens to them when they set their tablets to allow Wifi to sleep with tablet.
