I posted a question about this last week thinking it was a wifi problem, but it turns out it happens when I'm on data too, so it's an overall data problem... I'm just using wifi most of the time so that was the only place I had noticed it.
Occasionally my phone will stop being able to send/receive data. I'll turn it on and try to load a web page, for example, and it will just hang. Turning wifi on/off doesn't fix it, and turning data on/off doesn't seem to fix it either. The only solution I've found is going into airplane mode for a second. The frequency varies.. it seems to happen between 1-5 times a day, so it's pretty inconvenient.
I've read around a bit and it sounds like it's caused by the phone trying to get a 4G connection but it isn't able to or something, so it just hangs there and never lets the 3g/wifi connections get used (due to priority of connections or something). I almost always have wifi and don't care that much about data speeds, so if disabling 4g altogether would fix the problem I'm game (although I'd prefer another solution...). I tried the *#*#4636#*#* code to change it to GSM only (I read somewhere that that'll disable 4g), but it instantly reverts back to what it originally was, so that doesn't seem like it'll work. Is there another way to disable 4g?
I've got the stock ROM running Entropy's latest DD kernel.
I've had this same exact issue while running Miui and the Siyah kernel. What I've narrowed it down to is likely to be some sort of power save mode that kicks in when the phone goes into deep sleep mode. I haven't had the issue since I've ran the Kernel cleaning scripts and reflashed the latest Siyah kernel, but it reappears occasionally. On certain releases of Siyah, I've ran SetCPU at a minimum of 200Mhz to keep the phone from going into deep sleep just so it wouldn't turn off the cell radio.
Also, as a side note, I've had this happen when my phone loses signal. After so much searching, it will turn off the entire cell radio and display "Emergency Calls Only" until Airplane mode is toggled.
I had this same problem even back with my Captivate. Hoping ICS won't have the same issue. I'm running CM7 and Siyah kernel.
I am having the same problem Data wont work until i turn airplane mode on and off
I am having the same problem Data wont work until i turn airplane mode on and off.
Have you found a resolution?
I have seen various posts about this, but my MX2 ... no matter what the wifi sleep policy is set to, it always seems to lose wifi connectivity at some point. I also verified the battery was set to "performance". I swear I saw some hacks a while back to fix this but I must have been smoking something as I can't find them. Thanks much in advance.
Oddly enough, it seems the phone doesn't disconnect if it is connected to an open network. If I have security enabled the phone seems to completely disconnect and have to reconnect after you turn the phone back on. Although regardless the phone stops responding to ICMP traffic no matter what type of network it is on after a bit of having the screen off.
I have had this issue since the last update in oct. I have spoken with Verizon's tech(non)support 20 times and I'm on my 3rd X2 . With me not only does my wifi go to sleep but so does the cellside of the phone . I would receive a voicemail alert an hour after the phone didn't ring . Verizon's answer was to master reset the the phone which I did once for them(it's their answer to everything, any glitch whatsoever and they want you to reset your phone). Anyways I have since rooted the phone and now use their signal exclusivley during working hours(wifi hotspot). Thats seems to be the only answer to me using my phone online and it not going to sleep .
I'm running cm7 on my dx2. I have some wifi issues with it and am running wpa/wpa2 on my wifi. I started using wifi keeper running workarounds 1 and 2 and haven't seen as many issues, so maybe try that?

All,
I'm having a problem under two different ICS Roms (the "unofficial" leak and the ICS Objection RC3) where when I disable WIFI or move out of wifi range it takes several minutes for the data connection to establish. If I go to Settings -> About -> Status and watch while turning off WIFI I see "Mobile Network State" go to Connecting... and "Mobile Network Type" flip between HSPA:11, HSPAP:15, UTMS:3, then settle on HSPA:11 for several minutes. Then it flips through them again and settles on HSPAP:15 and boom I have data. This doesn't ALWAYS happen though, but about 90% of the time it does.
I've seen a few people mention this but nothing widespread in the forums - I'm worried it's related to my phone specifically. I flashed back to the stock gingerbread and the data switches are instantaneous every single time, so it doesn't seem to be hardware. Since this only happens on the ICS roms I'm assuming it's related to them but not sure where to check next. Any kind souls have any ideas to help me move forward? I'm currently on the ICS Objection RC3 rom and really don't want to go back
Thanks
I am having the same problem, I am on the stock ucle2 leaked rom not rooted, and it just started happing. After my wifi being on overnight I wake up and go to leave my house and my 3g/4g will not turn back on, I found that if I turn airplane on and then off again my data will turn back on. Does anyone know what would cause this, and any ideas on how to fix it?
Recently I disabled the best wi-fi performance option (I enabled it on accident while messing around with settings on launch day) which obviously increased my battery life dramatically by actually allowing my phone to go into deep sleep. But now I hit a new issue.
Before I go on, I want to state that I DID apply the SmartSync fix and that my data IS working while my phone is in deep sleep.
New emails I receive with Gmail app do not get pushed to my phone as they should. They are anywhere from 5-15 minutes late if they even show up at all. If I happen to turn my screen on, automatically I get the notification of new emails.
Is anyone else having this issue with Gmail or any other app? I find it strange that while I have data (wi-fi/3g) enabled and working with the screen off, emails still come in delayed.
Any help would be appreciated. I have searched around and most of the answers I came up with (regarding HTC devices like the One X) had to do with SmartSync messing up the connection or someone not having the notifications enabled. I'm at a loss 0.0
EDIT: I tested this with Google Talk had my main account up in Gmail and in another browser windows my other Gmail account. Added both of them, talked to my self, if my device screen was off, I would either get it 1-2 minutes late or not at all. Once I turned my screen back on, the notifications poured in. I also tried the same scenario with my main Gmail account logged off (in case it was canceling out the messages to my phone, which it wasn't) and I had the same outcome. I edited the title to reflect that this isn't a Gmail only issue.
EDIT 2: Did more tests, I tried turning Wi-Fi off completely and running the same tests as above to my surprise everything worked as expected. I initially thought it might be because of my 5Ghz Wi-Fi band, so I tried it all again on my 2.4Ghz channel -- had the same problems as before. Somehow the issue pertains to your screen being off and Wi-Fi being on.
EDIT 3: I just tried streaming Pandora and shutting the screen off (maybe WiFi WAS somehow shutting off) Pandora kept playing no problem. I messaged myself on Talk, got the notification right away. This is very bizarre 0.0 But it might confirm this only happens when the phone is in deep sleep mode... Still doesn't answer why it doesn't happen on 3G or why notifications sometimes still come through.
EDIT 4: Still no fix but I have discovered that for some reason if the screen is off ANY data doesn't go through. Let me explain better:
If I have some thing like Pandora running then it will continue to run once I shut my screen off. But if WiFi isn't being used and I turn my screen off and then lets say I try to connect to it with Cerberus or ping it from my PC or something it will not even though the router reports it as connected.
Very strange behavior.
This is interesting...maybe the wifi performance toggle is associated to the smartsync, and all?.....I will say that with it unchecked I am getting some really really good battery life here compared to previous phones....but I also notice at times when emails are not pushed till I wake the screen during the day....Also the fact my wifi doesn't automatically reconnect to my house when I get back from work till I wake the screen...little things like that...
Havent messed with the best performance setting but will try it today now...

Try installing this https://play.google.com/store/apps/details?id=com.logicvoid.powersaversettings&hl=en and unchecking "put data connection to sleep." It may not solve the issue but its worth a shot.

Have it, and it is unchecked. That's the weird thing, wi fi doesn't actually turn all the way off because SOMETIMES I do get the push notifications (late, however).

what is the smart sync fix?
When I installed this app, my cpu reduction and frame rate reduction was enabled. Does that mean this is standard with this phone. Does using this app to disable those setting improve the performance?
Issue continued overnight, tried various other things and nothing seems to fix it. I want to get my notifications but I don't want to destroy my battery life xD is anyone else having this issue?

It's definitely not a hardware problem because if that was the case the phone wouldn't work with wi fi almost at all. My wi-fi connection is rock solid even when the screen is off, just for some reason it won't notify I have the messages until the screen gets turned on.
I did some tests on my gf's stock phone and she's having the same issues, I told her to do some tests on her parents wi-fi when she goes there. I wonder if sgt slaughter has any news.
Btw if you definitely need them on time and need to be on wi fi but don't care about battery life that much just enable best wi fi performance.

Actually more like a Smart Sync break ... The built in settings/app put your data connections to sleep when your phone goes to deep sleep; this is done to save battery when phone not in use for extended period.
Some folks hate losing the data connections so a flashable "fix" is available for the "problem" ... Look around; you'll find it

its a sense problem, there's a thread in the one x forums on how to fix it. I'll post when I get home if I can find it. it shuts down to a 'power save' mode after a while plus after midnight or 11 or something.
Just wanted to update that I installed a custom rom that contains the WiFi fix mentioned and although my WiFi doesn't seem to drop how it did before (at least after one day) my notifications are anywhere between 4-10 minutes late on average through WiFi. This seems to be across the board for Exchange email, Gmail & Google Voice.

Yes my setup also had the wi-fi fix, I can even see my phone connected to the router when the screen is off, the connection is strong.
I had a suspicion it was probably the basic transfer rate of the browser and for some reason I could not adjust this on my fancy 100 dollar router with dd-wrt flashed onto it so I set up a repeater with my older router on stock settings. It seems like the notifications are coming through better now (albeit not instantly) but at least I don't have to turn my screen on every time. It might be a placebo effect or just luck (because at times it does work even with my other router).
EDIT: Ignore the italicized sentence. It was just a stroke of luck, the problem came back.
I'm out of ideas at this point xD
I am having a similar issue as well.
I am rooted and running Fresh Evo LTE 5.1.1 which has the "Disabled SmartSync deep sleep mode" already installed. I also leave my WiFi off (for the same reason as the OP outlines - messages are just plain not arriving or if they do it's after I turn the screen on).
I use gtalk as my primary form of communication on my phone and what seems to be happening is messages from my two closest friends are never arriving. It's hit or miss but seems to be ~45mins after my screen turns off that they send a message and I never get it. One is on Sprint on my family plan and the other is on Verizon. The weird thing is that if I look in my gmail > conversations the messages aren't there either.
I haven't been able to verify any SMS messages that I haven't received but I have noticed that my email notifications seemed a bit wonky but this issue may be fixed with changing my "push" hours (which is retarded to have factory set to only push email between 8am - 8pm).
Question for the smart kids in the class: When does the phone reach "deep sleep"? Is it around ~45mins after the screen turns off?

I also have the dual core mod which I BELIEVE sets my deep sleep right away which is probably why I have the problem more often than you do. One question just so we can start gathering facts large scale, if you're on 3G do you have the problem still? What if you turn 'best wi-fi performance'?

Correct - I have this problem on 3G. I run on only 3G because the problem is more prevalent on WiFi, but still very common on only 3G.
Currently I have "best wifi performance" turned off. Do you want me to test with it on or off?

On. When I turn it on it pretty much eliminates the issue, it acts just like 3G. But for me 3G is almost perfect (a couple seconds of delay but I can deal with that). Remember though that if you leave it ticked on it will destroy your battery life.
WiFi is on, best WiFi performance is on as well.. I'll run it this way a couple of days and see if I can replicate the problem.
I just wanted to say that I've been having similar issues. I have tried turning on best wifi performance, but I don't think that is helping. For one thing, when I have that turned on, when I wake the phone, the wifi is often times not connected, and it shows 3G. Then it will connect to wifi shortly after I wake the phone. On top of that, I'm still not getting notifications on time. I was notified of an email when I woke the phone that actually came in 10 minutes earlier. Hopefully HTC/Sprint is aware and working on a fix.
Still no fix but I have discovered that for some reason if the screen is off ANY data doesn't go through. Let me explain better:
If I have some thing like Pandora running then it will continue to run once I shut my screen off.

Hello, folks!
I have a rooted I9100 (Android 4.0.3 stock from Vivo, baseband I9100VILP3, kernel 3.0.15-I9100VJLP7-CL371396 [email protected] #3, compilation IML74K.VJLP7, CSC I9100UVILP3).
Sometimes I have problems turning on WiFi, it keeps always turning on and neither become active nor allow me to turn it off again. I then need to reboot phone to fix it (when it reboots, WiFi comes turned on and gets on normally).
Another problem I have with it is that sometimes (average of 4 - 5 times a day) phone loses registration with carrier. It completely loses* signal and shows a "prohibited" icon where signal strength is shown at status bar. (Edit) Sometimes it comes back again in a few seconds and sometimes it stays at that state, making me have to reboot it to fix the problem (turning on and off airplane mode doesn't work; in fact, with registration lost and trying to use airplane mode, it doesn't turn off and only fixes with reboot).
*Actually, it doesn't lose signal (can be seen in "settings - about phone - state" screen uploaded), but only unregisters from carrier.
(Edit: screen/phone language is Brazilian Portuguese)
I've downloaded another modem driver but never had time to test it.
I don't know if both problems can have the same cause, but both of them are very annoying (especially signal loss) and I'd like to make some tries to fix them, so if anyone knows what can I do (even data collection to investigate them), your help is very appreciated.
Thanks
Additional test (ServiceMode)
When I was in the forum to post this thread, I've noticed this other thread and I've decided to use ServiceMode code (*#0011#) to investigate further at the next time my cell lose signal. Unfortunately, it showed absolutely nothing. Literally nothing (just "ServiceMode" caption and no text on the screen below).
I just spent the time to post this because I know that, even if it has shown no information (on screen), maybe it still can be a clue for the cause of the problem.
Thanks
Pls help!
Does anyone have some light to shed on this case?
Please, I do really need to fix it, at least the signal loss problem.
Thanks.
Same Issue in the US on Tmobile
Mine started doing this just a day or two ago. Exact same issue. I can kind of operate on the EDGE network but 4G fails, only WiFi seems to work. T-mobile doesn't seem to have a fix for it.
Changed to MIUI
I've just changed to MIUI (reflashed modem also – now it is ZSLPE instead of previous VILP3).
I still have issues with carrier register loss, but until now it always reconnected after a few seconds. Maybe it is a carrier issue and not a phone one.
I don't turn on WiFi a lot, but all times I've tested it, it worked well.
Another thing I've noticed with this change is that battery temperature while charging used to reach 48°C (118°F) or even 50°C (122°F) while battery level was low (less than 50%), but now it stayed around 35°C (95°F), which is completely acceptable.
