I got my gTab on Wednesday and so far I am very happy. I played with the 3588 stock ROM for a day and got a lot of force closes, so I switched to TNTLite 4.4.0. I initially had some FCs with that too, but after switching to Launcher Pro and Dolphin and doing the step 6-7 of the market fix it seems to be settling in.
My problem is that when I bring the gTab out of standby I sometimes have to turn the WiFi off and then back on in order to get a usable connection. It comes out of standby and says it's connected, but I will get nothing but 404s until I power cycle the WiFi. It doesn't do this all time, but it's enough to be annoying. I use a WPA2-PSK network with AES encryption. Any ideas?
Happens to me too. I'm thinking that disabling wifi on sleep might work for me. Depends on how fast it comes back on at wake.

I've disabled this and it is still iffy for me whether it comes back automatically or not. I've taken to just cycling the wifi every time. having a widget helps with this.
I'm having the same issue too. I'm running the Vegan Rom 5.1.1 and after waking from sleep wifi shows connected but I can't use any wifi resources until I kill wifi and then restart it. Then all is well ???
I switched from TNT Lite 4.4 yesterday to Vegan 5.1.1 and I am still having the same issue. Any ideas?

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.

"WiFi stay alive" will help you!

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
app was playing for about half an hour with screen off
I hear that ubuntu might run on this - it would be great to
have a **real** operating system to fiddle with
So I'm rooted and have the latest/corrected 3.2 with pershoot's OC kernel...and nothing else. I noticed when I wake up my tab sometimes it will reconnect the WiFi sometimes it won't. Not sure why it's spotty. Before it used to reconnect almost instantaneously every time without fail. Is there a fix for this? Am I missing something?
I've got the same problem.
Nevertheless, the wifi code is store and don't ask for it
same problem
Ditto. I've resorted to just leaving it in the "always stay connected" mode even when the screen is off. Eats a bit more battery, but at least I don't have to toggle wifi every time I turn it on.
I've got the same problem on a brand new Tab 10.1N (special version for germany) WIFI edition. The tab came with Android 3.2 stock installed. First i thought it is my wlan ap which is causing the problem but it happens also on 2-3 other aps i've tried. I find this very annoying, especially on this high priced device... hopefully there will be a bugfix release soon.
So I did find out what the issue was for me. It was the Ad Free app. For some reason everytime I woke my Tab up, if the Ad Free message didn't come up neither did WiFi. When it did come up, WiFi would auto turn on again. So I removed this stupid thing and voila problem is resolved. Not sure if it'll work for others b/c like I said I'm rooted and Ad Free is a rooted app. Good luck though!

I have the same problem. Remove Ad Free, but the problem remains
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 been impressed with CM11/4.4.2. Runs well for being so new and not yet having an officially 'stable' version yet.
The one issue I have had is with the WiFi restarting after sleep.
KeepWifiOnDuringSleep is set to OnlyWhenPluggedIn. Whenever the tablet is awoken the WiFi stays disabled. Manually turning it off then on again will get it to reconnect but only for a short time, maybe a minute, before it permanently disables again. Only way to fully recover is to reboot.
Note that WiFi is be reported to be 'disabled'. It does not appear to be an issue of connectivity, wireless lease, no signal...
Anybody else experiencing this?
I successfully use an app called WiFi Fixer to reconnect after sleep.

That's been an on-and-off issue for ROMS going back to CM7. The work around has been to turn off WiFi before the screen turns off. Many folks have been using AutomateIt or Tasker to handle this automatically.
