Hi I have wrote an email to Sony support couple of weeks back and finally got words from them today. Below is the content of the email:
Hi [myname],
I have finally had a response from my Technical service division about your issue with the tablet, they replied that the issues you were experiencing were rectified by the latest software update, after informing them that you have already applied this update this is the response I got.
Hi [customersupportrepsname],
When the power button is pressed, the device enters into Sleep or Display off mode. When the system enters into sleep mode, the Wi-Fi is disconnected even if “Wi-Fi Disconnect Policy” is set to Never.
The running applications judge whether the system enters into Sleep or Display off mode.
For example:
Sleep = Applications that accepts sleep - Browser, Reader, Camera
Display Off = Applications that refuse sleep - Music player, Music, Remote Control
If the customer wishes to never disconnect from the Wi-Fi, this can be the work-around:
When the AC adaptor is connected, it doesn't shift to sleep mode by the following methods.
1.Tap [Settings]-[Applications]-[Development]
2.Check Stay awake
So unfortunately [myname] I’m not sure what you would like to do from here. Obviously the work around is not ideal as the main reason for using the Wi-Fi connection is that it need not be connected to a wall outlet of any kind.
It may be a case of taking the unit to an authorised service centre.
You can find the nearest one here:
http://www.sony.com.au/section/servicecentres
Select computer from the product category dropdown menu.
Kind Regards
[customersupportrepsname]
Interestingly Sony doesn't think of it as a glitch, it's just the nature of the OS. And I'm not sure what 'taking the unit to an authorised service centre' gonna help me if it isn't a problem.
Disappointed. It doesn't make any sense.
Why we can't stay connection after Sleep or screen off or any circumstances?
It makes me feel the connection policy is useless.
BTW, Thanks for posting this
Yeap exactly. I'm still in touch with the customer support rep, telling him that sometime(rarely) it does stay connected to the wifi when it sleep. If this is the nature of the OS, other honeycomb tablet should have this problem too. Does anyone else have other tablet to confirm this?

This is definitely not a honeycomb problem. Tried it with the Xoom and the new Galaxy Tab, both work as supposed to when switching to Never disconnect.
This is also not the first discussion in here, so I dont get why we need yet another thread about this.
Read more here. There u'll also find a workaround on how to fix this problem.
Since Sony obviously doesnt see it as a "bug" we wont get a fix anytime soon. (Maybe ICS will solve it)
And their supposedly 'workaround' is a f*ckin impudence imo.
I urge anyone who wants to keep their WiFi always on, WRITE AN EMAIL to Sony. We wont get a fix if we only complain in here (or other forums for that matter) and Sony's not interested in one or two email complaints. I didnt even get an answer anymore after my 5th or so eMail, but if they'll recieve more n more they have to act at some point!
If you do email Sony make sure you copy & paste the thread url about the complaints into the mail. My customer support rep claimed that he have a read on the link i sent him. At least let sony know how annoyed their customers are if sony didn't already check this website.
I have problem with 3G. When I turn off wifi, he does not turn on 3G and show me no internet connection. I must restart tablet to use 3G :/

I have a GTab runn Vegan 5.1 and it runs great. The one issue that I have is that my Wifi gets disabled each night when it goes to sleep. When I say "disabled" I do not mean this it disconnect, but rather that something is actually putting it into a "Disabled" state and I must select the connection and choose to enable it.
Does anyone have any thoughts on what could be doing this? I have dug through every setting I can think of and also looked at any apps that might be doing this. I even went so far as to remove all my battery saving apps, but no dice.
Any suggestions?

Have the sleep policy set at never and this does not change anything. From what I understand this setting will disconnect wifi when the device goes to sleep. In my case the connection is not disconnected but rather completely disabled. So it seems that there is some other thing disabling the connection.
So, to give a bit more info here, I have installed wifi keep alive to try and save the connection. This keeps the wifi from being disabled when it is plugged in, but it still gets disabled when it sleeps and is also unplugged. (I.e. on battery and sleeping)
So, I am starting to think that the setting that fixes the problem while pluggedin is settings / applications / development / stay awake. I have this turned on and it seems that with stay awake and the wifi keep alive I am good when plugged in.
So, does anyone have thoughts for a similar setting when on battery power?
I can't help to much with battery power since I almost always have mine plugged in.
It's odd that not helping you, once I made that chance I stopped having my Wifi turn itself off (not sleep, off, and the tablet would need to be reset a lot).
Sorry that wasn't much help.
Having this problem as well. Anyone know how to fix?
If you notice other weird stuff happening in the future you may need to repartition your internal memory. Mine started with similar flubs and progressed to never remembering logins online. I had to login to xda every time I turned my device back on. Keep this in mind, about 30% of people need to reformat.

can you give some info as to how one would go about doing this?
For what its worth, might help to set a fixed IP address. I often got a problem with Wifi not being able to reconnect because it got stuck on "getting an IP address" and failed to do so. I seem to remember it disabled the connexion to that AP after too many tries on my Nexus One.
On my g tablet, I was having what seemed to be the same problem, so I did the same thing and it seems stable since. Granted I didn't toy with it as much as I did on the N1, but I wouldn't be supprised if it were a general Android problem.
Anyways, its free to try.
The wireless uses a lot of power. When the tablet "sleeps", it should go into a power saving mode. Disabling the wireless is a feature, not a bug.
Either way how can I keep the wifi signal on so when i wake my g tab up the wifi is ready to go and does not have to reconnect?
anyone have anything to help with this?
I am not sure, but it seems to me that downloaded apps can play with wifi this way, as long as they have rights to "access internet, modify and bla-bla-bla".
I am having same problem after sleep. And it was not present from the beginning. It may starts after I upload some app. I will play with this after coming back home.
yes please let us know thank you!

When my tablet is plugged in and it goes to sleep, the Wifi also disconnects, so I don't think this is a feature any more than the screen angle issue is a "privacy feature." I've never had an Android device that powered down connectivity when the screen goes off, that totally negates the notification features. You basically have a comatose tablet after a few minutes of the screen being off.
I don't think the Xoom or Galaxy Tab have this problem, so there's definitely an issue. Sadly, I might be sending mine back to TigerDirect as faulty because of this.
I have this problem too. As others have said, the problem isnt that the wifi turns off when the tablet sleeps. The problem is the last connected access point gets disabled so when you wake, you have to go into settings and tell it to connect again.
In my case, it happens most of the time, but not always. My Android phone doesnt have this problem.
I did a factory reset, then used nvFlash to restore, and then did a fresh install of Vegan (thought it did the same on every other 2.2 ROM I tried). I didn't install any apps, and the problem still occurs. Tried using Wifi Fixer, and the problem still occurs (though on the bright side, it does reconnect about 10 seconds or so after waking).
I'm out of ideas. I hate to send this thing back because it's the most fun piece of tech I've had in years, but a comatose Android device is a dealbreaker Going to try a GB ROM, and then I give up.
I've got the same kind of issue. I lose my PSA key in my wireless settings every time and have to re-enter it.
I installed the Vegan GB ROM (along with pershoot's kernel), and the wifi stays on if you choose "Never" for wifi sleep (you have to hit the menu button and choose "Advanced" when you're in the wifi settings). Only problem is, the GB ROMs, while zippy, are a little raw right now, and my Launcher Pro GMail widget doesn't work
I'm going to try one of the 2.2 ROMs again today along with pershoot's Froyo kernel to see if it makes a difference.
Ok, YMMV, but I am using Calkukin's ROM with pershoot's kernel (was using Clemsyn's before), with wifi set to never sleep, and my wifi doesn't sleep any more. I left my phone and tab here at work while I went out for lunch (felt naked ...), and came back about 45 mins later, woke the tab, and wifi was still connected, without that "looks connected, oh the icon is now disconnected, oh it's back again!" bit.
I still receive notifications and email, and widgets update. Guess I'm keeping it
Hi,
My mozart is working fine with wifi, however just curious what I noticed:
as soon as i enter my work place or come back home my mozart gets connected with the wifi at each location. I noticed taht while Mozart is conneted to wifi, if it gos to lock state (screen black out after 1 minute) then it gets disconnected form wifi and while in locked state (power safe) it use hte data bundle allownce. is this the case with all or am i missing some setting here.

Unfortunaltey I don't have my sources here, so I cant forward them to you. MS confirmed this was a feature, not a fault. It is built in to the operating system to prevent the battery from draining too fast due to the continuas WIFI usage.
So in order to be able to recieve TOAST and TILE notifications it enables the cell data. Shouldnt be much though, couple of kbytes.
I can't remember if they were gonna make a setting to avoid this in the future, but the original article on MSDN I read about it didnt mention such a "solution". I think microsoft will go for the "its not a bug, its a feature" approach. Feels kinda legit though. Worst concern for any smartphone user these days is battlife.
Thanks Sirstoner, it makes some sense and wish we get long life batteries. thanks.
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).

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. 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.
Someone started a thread a while back on this, but I wanted to start my own hoping that this issue may get a little more attention, and keep a detailed thread for future use. I love this phone, but this is the one significant issue that I have.
I spend most of my day and evening on wifi since I have it available at work and home. I've noticed since day one that I wasn't getting my notifications on time specifically in Gtalk, and still exists to this day after the latest 2.13 OTA update. When I hear my phone get a notification, I will check it, and the notification has a timestamp in the notification drop down, so I know I got it just then, but then in gtalk the timestamp on my message is several minutes earlier. I have seen it as much as 45 minutes late. It is very noticeable whenever I turn on the screen that instantly I get a notification. The issue exists with all push notifications. Gmail notifications will arrive late as well as exchange notifications. I've seen reports about it happening with WhatsApp messenger. It has been theorized on other forums that the wifi radio goes too deep into sleep for the notification to wake the phone up.
My wifi policy is set to stay on always. I've tried factory resetting. I know that the wifi stays connected while it is sleeping and is not disconnecting. I've tried multiple wireless networks. I've tried 2.4ghz vs 5ghz. It has nothing to do with smart sync disabling data as this is happening during the day and not between the hours of 12am and 7am.
I have done a lot of searching on Google about this issue, and I've determined that it is an issue with the entire line of HTC One series phones. People have reported this issue on the One X (International and ATT), the One S, Incredible 4g, and of course many other reports on the Evo LTE.
I have compiled many of these reports in a thread I opened on HTCs support forum site here: http://community.htc.com/na/htc-forums/android/f/222/p/15183/62995.aspx#62995
Please feel free to test this yourself. Connect to wifi, turn your screen off, send yourself a gtalk message from a separate account. If it comes in on time, wait about a minute and try again. If it doesn't come in, wait as long as you can stand or just turn the screen on, and see your notification come in. I tested this on a friend's Evo LTE who insisted he wasn't having the issue, and I was able to duplicate this. It seems that most people must not use wifi as much as I do, and maybe just haven't noticed.
Current solutions / workarounds:
Turn on Best Wifi Performance in the advanced wifi settings - kills battery
The best solution that someone found on another forum was to use an app called REGPON Wifi KeepAlive. It is an app that puts a partial wakelock on the phone in order to keep it from going into deep sleep. Check both boxes included in the app. The first starts the process, and the second will turn it off when wifi is disconnected. This doesn't have a huge effect on battery as I thought it would since it is putting a wakelock on the phone. I actually get very good battery life still, and can last through the day with heavy usage. It's nowhere near the significant drain that you get with the Best Wifi Performance option.

That could be considered a workaround, and I have tried it, but wifi doesn't go to sleep until after several minutes after you turn the screen off when you use that setting. Then of course mobile data kicks in and notifications come in on time.
Something that has been annoying me since the day I bought the tablet (LTE SPG 521)
When the tablet has been idle for a while, the WiFi turns itself off.
So whenever I pick it up without thinking, open chrome to start web browsing, I am connected to internet, and things are fine until I realise that I have been using 3G instead of WiFi.
Most of the time I need to go into shortcut quick access from pulling down top right corner and turn WiFi on.
Sometimes I need to go into WiFi settings and turn it on, even though the quick access shortcut says WiFi is on.
I do have stamina mode on, but have disabled every other power saving feature related to WiFi. In fact it is the same setting on my Z Ultra and Z1 Compact, but needless to say, I do not see this behaviour on my other sony devices.
But somehow on the tablet, WiFi does not auto connect, even in presence of a WiFi router that is set for auto connect.
Even If I was using the particular access point for WiFi connection, lets say I play games for about 30 minutes... the connection is lost and I need to go into WiFi settings to turn it on again (with the small slide to the right toggle switch within WiFi settings to turn on WiFi itself).
Anyone else experiencing this?
I would rather avoid it, since over usage on 3G for me means speed throttling later in the month...
P.S. Yes, I am on latest firmware 17.1.A.2.69
On Advanced WiFi, Keep wifi on during sleep is set to ALWAYS., avoid poor connection is turned OFF, and Wifi optimization is also OFF
Factory reset it? That's probably the first thing they tell you to do if you approach the technicians, if the problem still persist then demand for an exchange if not refund it.
I'd just bought mine today and unfortunately the bottom right corner the glass sticks out and it is pushable. I'm going to exchange it tmr.

Thanks for the idea, but no luck.
In any case each time I upgraded firmware, it should have sorted itself out, but problem still remains...
"Factory reset" is always the first "solution" you get by "technicians". Usually translates to: "Keeps the customer occupied for hours, silencing him."
Regarding the issue: I cannot confirm that, NO WLAN issues with my LTE Z2, it's just "always on", never losing the connection.

Do you have stamina mode ON?
With my other Xperias, the second I turn my screen on, the wifi is off/sleeping, but it launches and connects almost instantaneously. I guess the problem in my tablet is that it is not doing so, requiring me to do it manually...
I thought the FW for the tablet and the phone Z2 was the same? Maybe I should go and look in the forums over there...
I don't have the problem, either.
UPDATE
Problem Solved.
The cause was ad blocker app that I had installed, and it seems to me that whenever I was using certain apps that needed ad-blocking, all this thing would do is turn wifi off (but not 3g/LTE)
How Dumb is that?
Anyways, Wifi now always on even with stamina mode on.
Thanks for all who listened and threw suggestions!
Thanks

Thank you very much for sharing this with us. Too many others just keep silent if they found the reason of their problems.
