Hi,
I just bought a Sony Tablet S, amazing device. The only problem I'm having is that when the tablet is idle, or the screen shuts down, the WiFi gets disconnected and it doesn't reconnect untill I open the WiFi panel in the settings app.
Now before you guys jump to conclusions, yes, I changed the WiFi disconnect policy to "Never (uses more battery power)". That hasn't helped at all.
Any ideas? Is this just with Sony S or a generic Honeycomb thing? Tablet hasn't been rooted as yet.
Try Advanced Wifi Lock Free. It works well with my tablet.
This issue seems to be a bug in Tablet S. I hope they'll fix it in the ICS release
Yes, already discuss here...
You need to install a must have application...
Advanced Wifi Lock
https://market.android.com/details?...DEsIm9wb3RlY2guYWR2YW5jZWR3aWZpbG9ja2ZyZWUiXQ..
Worked
Thanks for the app recommendation. It's working...so far .
I bought my Tablet S 2 days ago.
Though I have heard of this issue before, my new tablet does not have this problem, maybe Sony has fixed the bug.
p.s. I changed the wifi disconnect setting to Never.
I started using wifi advanced lock a couple weeks ago and it works great! Much better than making sure the screen stays on during all your downloading
...Although I've noticed a massive change in battery life. Typically I was always getting 7-8 hours of screen on (gaming) time out of it, with up to an additional 24 hours of time with it on standby.
Now I got about 13 hours standby and 4.5 hours screen on time with wifi constantly on.
All I'm saying is to have a widget for turning on/off wifi quickly, and leave it off when it's not in use. I didn't think that wifi made THAT much of a difference..but apparently it does lol (and that was still without autosync on either)
I uninstalled that and use spare parts instead. Advanced wifi lock was horrid with my battery grrr
I think is normal, because if you put your tablet in standby is because you're not using them so why you need wifi on?
When you turn on again the wifi will reconnect auto again
WPS Wifi Lock
I had the same issue when connecting at my house, If you have a WPS enabled routter, connect to you access point using WPS. At keeps the signal locked.

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
I would like my gtablet to remain able to establish ssh connections
after the display turns off.
It appears even if I set the wifi preference to never go to sleep, once
the display turns off I cannot either ping or ssh into my gtablet?
So, I wonder if there is a way to do this.
(By the way, I assume that the wifi has power saving implemented
so just sitting around will actually not use much battery.)
I've noticed that when the screen goes off, adb even loses the tablet until you turn the screen back on. But I am having the same issues with Wifi, and setting it to never sleep in addition to installing a keep alive app doesn't seem to do much good. When the screen goes off for a couple of minutes, all connections seem to be lost.
It would be nice if there was some sort of solution to this.
yes, I can't get wifi to stay on. Basically, I want the tablet to stay
on but the screen to blank.
This is more important now that I have rsync installed and could
do automated data transfers or backups at scheduled times.
I am running Vegan 5.1.1 and am wondering this too, is it a vegan problem or gtab? Is there a dev that can make a kernal to stop this?
I am on a TnT ROM using Clemsyn's kernel, and I get the same problem, so it might be a device issue.
I'm trying out an app called Wifi Fixer -- free from the Marketplace (though I'll get the .99 cent donate version if this works). I left the tab display off and untouched for about 10 minutes just now, and wifi was still connected when I turned it back on. I'll let it sit for about 1/2 hour and see if it still works. If so, we might have a winner
In TNT (Lite), try Settings -- wireless -- Wi-Fi Settings -- Advanced Settings -- Wi-Fi Sleep Policy
wifi sleep policy is set so -- supposedly -- wifi never sleeps, but that did
not work for me (wifi was shut down when tablet goes to sleep - I wonder
what controls that - I would want display and system to have separate
sleep control ...)
But I found an app in market, wifi keepalive that seems to be working.
My tablet just turned off the display and I can still ssh, ping and rsync
successfully.
Maybe that is the solution.
I wonder how much power this will draw?
(I have a nokia n810 "mini-tablet" and even with wifi on (power saving
mode enabled) battery consumption is pretty minimal if wifi is not
actually in use. Does android use power saving mode in wifi?)
Well, I already had it set to never sleep. The Wifi Fixer seems to work though -- I let it sit for about 1/2 hour, and when I flipped it back on, the wifi was still connected.
Edit: Nevermind, that didn't work either. Sucks, I love this tablet, but if it's a dead fish when the screen is off for a few minutes, it's lost a good deal of usefulness to me.

That was the one I was using initially, but while it wouldn't drop the wifi connection upon turning off the screen, it would eventually drop it -- when I woke the tab back up, I'd have the wifi lost icon for a few seconds.

yep, it looks like that happened here too ... maybe some other
app is resetting this; it lost my connection after a radiotime

Hello, everybody. Newb here (only have had the HTC Evo View 4G for a couple of days now). I have a question about the battery and screen. Is it regular for the screen to use up about ~60 percent of the battery? (According the usage stats). I find that the screen is bright, even on the lowest setting.
Also, I have a question about the battery. It seems to be draining a little quick (I am using lowest brightness and WiFi only). Could some people share how long their battery usually lasts for regular usage? I don't think it's a hardware issue. Like I've said, I've only had it for 2 days, so I don't know if I still need to wait a little.
Thanks!
The screen is one of the biggest battery drainers (if not the biggest) on tablets. So if you are using the tablet a lot, and the screen is on for long periods of time, then 60% seems normal. I don't have my Flyer with me right now to check what my % for screen is.
Battery drain is going to depend a bunch on how much you are using your View, and for what. With moderate usage, I can get around 2 days on a charge. I'd say that is about average for me. But if you are downloading big files and gaming, and/or have the screen on a lot, it can be significantly less.

Okay, that makes sense. The battery life seems to be getting better. One more question. I want WiFi to turn off after a certain amount of time once the screen timeouts. Is there any way to do this in the settings or with an app? The settings (official 3.2) has a WiFi timeout policy that gives three options:
Switch from WiFi to mobile data when screen is off
Never switch WiFi off
Never switch WiFi off when plugged in
I live in Canada and don't have a plan. Would using the first option drain more battery because it is looking for a connection? Or should I use the third option?
Thanks again.
Hmm, not sure. I have the WiFi only version of the Flyer, and on mine the first choice is just "When screen turns off". The first choice on your View is weird. Mobile data always uses more power than WiFi, if both are available. I don't see why you would ever want that.
BTW, I'm at home and have access to my Flyer now. Battery usage for screen is 52% for me. So I'd say 60% you mentioned is pretty normal.
You should also take into account, unless you've taken steps to turn it off/remove it, Cell standby might also be causing your battery life to take a hit. Since the View is set up to also be able to receive text messages, out of the box it's constantly trying to connect to Sprint's cellular network, even if you have mobile data turned off. This thread discusses ways to deal with it. Cell standby used to be one of the biggest users of my battery. Now, it's no longer a problem and I've seen a major increase in battery life.
As for the WiFi issue, the first choice in the settings actually says "When screen turns off (uses more mobile data)." That doesn't mean that it automatically switches mobile data on if you've turned it off in the settings by selecting that option. It's worded that way because the View is designed to be used on Sprint's network, so under normal circumstances it is assumed that if you turn WiFi off, you'll have a data plan and automatically connect to the mobile data network. If you don't have an account with mobile data from Sprint, and you've turned off mobile data in the settings, it won't be an issue because you have nothing to connect to.

That makes much more sense.
Okay, thanks everybody. I really appreciate it. With heavy usage (basically using it all the time) I'd get about 6 hours and 10 minutes. Is that normal for everybody else?
Also, I have a couple of more questions, if you guys don't mind.
First of all, could rooting my device boost my battery life? Would it give me more access to settings like screen brightness?
And, do apps running in the background use battery life or are they 'frozen' until active? This sort of leads me into my next question. Is having 400-500MB of RAM always being used normal? Is the OS using all of it?
And I notice that when I put my tablet in airplane mode (to kill the 4G radio) I lose access to Bluetooth. Is this normal and will turning off airplane mode for a minute be a battery drain?
Thanks again, guys.

Answers:
Rooting won't necessarily boost battery life, but does give you ways to access more system items if you want using apps that take advantage of root.
Android attempts to keep non-rumming apps in memory so that it can load them faster in the future (Ram is much faster than SD memory). 80% Ram full is typical.
Airplane mode turns off all radios, BT, Wifi, GPS, 3g.
There are apps in the market that can turn various things on / off based on your environment / time / conditions

You don't need root access to adjust screen brightness. Settings -> Screen -> Brightness.

Airplane mode turns off all radios initially, but then you can turn almost all of them right back on (except for the cellular radios). I run mine in airplane mode all the time to keep the cellular radio completely inactive, but I still use WiFi, GPS, and Bluetooth when I need/want them, and they all work great. Are you running Gingerbread or Honeycomb? I do seem to remember some mentions of not being able to use Bluetooth in airplane mode on Gingerbread. It works perfectly fine on Honeycomb.
And you can turn off the 4G radio and all data service without turning on airplane mode (Settings -> Wireless & networks -> Mobile network). Doing this turns off all radios that receive data from the cellular network, but it doesn't turn all cellular functions off since the View is also set up to receive text messages. That's what airplane mode or any of these options address.
What I meant by adjusting the screen brightness was being able to control its range more than I can right now (I feel that even the lowest setting can be too much). But it seems that rooting/installing a custom ROM wouldn't do too much for the battery.
But my issue with airplane mode is that I can't turn on Bluetooth with it (Bluetooth is 'grayed out'). I am running official Honeycomb.

Did you try tapping on the box for Bluetooth in the settings even though it looks like you can't, and did you try using a widget to turn it on? I'm using stock OTA Honeycomb, and Bluetooth works perfectly fine for me while in airplane mode. I can turn it on in the settings (the box does look a little "grayed out," but you can still select it) or via a homescreen widget. If you can't turn it on with either of those, then it would seem that you've got some other type of problem. It works fine for me. I just tested it out again.

I just tried it. It seems to not be working for me, but it doesn't seem like a glitch but something built into the OS (I tried with a widget and it did a little 'no' animation). It's alright, I rarely use Bluetooth anyway.
Thanks for all of your help (plus everybody else, too)!

I'd venture to say it's not something built into the OS. If it is built into the OS, then there's a glitch that allows me to use it under the same circumstances, and glitches rarely enable functionality. They almost always cause a device to lose functionality like you're experiencing. I'd be curious to know if anyone else is having the same issue you're having.
Last time I have ran battery test on my Flyer I ran it for almost 11 days on one charge. Yeap, 11 days. I mostly used Flyer as a notepad, checked orders on website couple of times a day, read emails. One day I played a game for about 20 minutes. At the end I set up and tested Plex and Google Music. I stopped the test at 11% charge. Overall screen was on for a bit over 4 hours (40%). Wi-fi on for 16 hours (only 4% ??) according to stats. That's pretty much it. Tablet idle 43%. Fairly light usage, but I mostly was testing how much of useable time I can get out of it. 11 days is a pleasing result.
I like keeping my wifi on while my screen is asleep so that I can receive chat messages or e-mails without being at my computer. I never had this problem while running ICS on an unrooted TF201, but ever since I installed the upgrade to JB my wifi will always disconnect after the screen has been asleep for a few minutes. I've checked every setting I can think of. In the Wifi Advanced menu, I have it set so Wifi is always on, and in the ASUS customized setting I have Disconnect network during sleep to off. Under Power Saver I have Enable low battery settings off, set Low battery level to 0%, and even set Wifi OFF to off. Despite all of this, it seems like the tablet under JB goes into some sort of deep sleep and disconnects the wifi after about 5 minutes of inactivity.
I have noticed that this problem does not occur when the screen is on. I also have the dock, and set the screen to always on during meetings in the event that I don't need to enter any notes for a few minutes so I don't have to fool with any delays from screen wake .
Is there some setting I'm missing? Is it a hidden setting that I could access by rooting? Or am I dealing with something internal to the build that I can't change at all? This may not seem like a huge deal to most, but it has become one of my main uses for the tablet when I'm at home. I'm very disappointed with JB so far even though the wifi does feel more responsive on the Prime after the update (when it's not sleeping, of course!).
EDIT: I noticed this evening that the wifi turns off even when I'm running something that uses it while the screen is off. I was listening to Pandora, and about 5 minutes after the screen went off, my music stopped. When I turned the screen back on, I saw that the wifi had indeed become disconnected.
hey,
I have exactly the same problem with my tablet. I have checked every option, I did a factory reset several time, I have checked it on 2 different routers but it is still disconnecting the wife when it goes in the sleep modus. Did you or anyone else find a solution?
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.
