I have noticed a few times that when I booted up my tab, the wifi would be greyed out, but it would still say it is connected.
I would not be able to surf or anything though.
I would have to disconnect and reconnect, or turn off then turn on wifi to get it back.
Anyone seen this? I have noticed it when my battery is low. This last time I checked and I was at 36% battery. Maybe some type of power saving thing? I would not think so cause I have not changed it out of balanced mode.
Does it sense a low batter (under 40%) and disable the wifi?
The wifi symbol is showing in the task bar, but it is grey (instead of blue)
If this is not normal, it is going back (but for some reason I remember it doing it with the first one I had when the battery was low)
If I recall correctly, the wifi icon will be grey when it can't talk to Googles servers for whatever reason or if you don't have any kind of Google sync setup.

Has anyone experiencing wifi won't connect once it wakes up from sleep. Mine is running the latest 2.2. My wifi keeps turning on and off in a loop until I put it back to sleep, and it does ok. 2nd time.
Any ideas or suggestion?

I have 2 Gtabs... from my garage lab 1 shows 3 bars to basement router, other shows 1 bar to same router... the 3 bars one wakes almost everytime cleanly... the one bar (weaker) one shows similar problem to your's... I loaded power widget on top of one on my homescreens and just use the enable/disable wifi button to retry connect when it doesn't wake first time (else loops trying till disable/enable) and that has always fixed it for me on the tab having weaker signal (bad internal antenna????)...
Well I don't think it has anything to do with the signal strength since no matter where I am close to the wireless router.

I think this has been an issue with TnT stock (and Lite) since Day One. I usually leave the WiFi on even in sleep mode (in WiFi Advanced Settings) which seems to help.
Or, I use a WiFi widget to just turn off the Wifi before I put it into sleep mode.

Thanks. It is good to hear that I am not the only one. Yes, I have started using widget to force things.
I am going to try that advanced settings to see if it works. So far I think it happens when it goes to deep sleep overnight.

You may be on to something, since my previous G (first 1000), was very picky as mentioned and newer G much better.
There are more then 1000's of these are out there? Anyway to track them by the serials? I have $279 version may be the earlier model.
Hi all,
I just got a Droid 2 Global today and I notice if you leave it alone for a while (which is hard to do with a new phone) the WiFi will turn itself off. The first thing I do with new Android phones is turn the WiFi Sleep Policy to "Never". And that is what I did today, but it still appears to be sleeping.
When I wake the phone I notice that the WiFi is off (Both up in the notification bar and the widget is dark) and the 3G is off as well. The only that is showing is bars. In about 5 seconds the WiFi will turn back on and connect.
Now this only happens if I don't play with the phone for a while. Turning the screen off and back on the WiFi will be on like normal.
As this annoys me that it is doing it, it is the 3G is off at this time as well. Which means the phone isn't getting any data during the period that it is off. Which isn't good since I rely on Google Voice for all of my texting, which won't come in unless there is a internet connection.
Any help on this will be great,
Thanks
I did find out what was going wrong last night. In Settings>Battery Manager>Battery Mode it was set to Nighttime saver. That would have been bad because I work 3rd shift and I'm up and using this mainly at night.
Hi guy, my wifi won't turn off when my Xoom is on sleep. I have set the settings of 'keep wifi on during sleep' both to 'NEVER' and 'ONLY WHEN PLUGGED' but nothing happens. Wifi stays on and keeps draining my battery life. I am running rooted with the latest version of nightly 62 and I've been having this issue since 55. I have reinstalled, flashed, factory reset, wiped my Xoom.
Is anyone else having this issue? What should I do?
From my experience, wifi stays on for a little while longer after device sleeps. However, some apps in background may trigger wifi back on again. So I turn off wifi when i go to bed. Actually i notice wifi itself will not drain much battery, 1-2% for 10hr. It's the host apps sucking the juice.
I am not an expert though.
OK i've also checked it out and as you said wifi turns off after some time. My main problem now is that my battery life won't last more than 3-4 hours on wifi.
I have posted my battery stats with use of web browsing and watching pictures on gallery...

What do you mean "no more than 3-4 hours"? In your battery chart, you can get more than that even starting from 75% battery.
What I wanted to say is that I think my battery won't last more than 4 hours with wifi on and some serious usage.. from my stats as I can see I've been using it 5 hours but I only had screen on and browsing the web. I think there will be a huge difference if I am watching a movie or playing a game.. I don't have the time to check it now but I will post my results in some days..
According to my previous battery graph do you see any problem or something less from what your Xoom battery holds? Does this battery drain seems normal to you?

I think you'll find it will stay on for about 15 minutes. There is some setting in a system database (using a sqlite editor) that can be changed to bring this down. I doubt Wifi is what's draining your battery. Are you synching email via activesync or running other stuff in the background?
I am only using my yahoo mail from the EMail app. I don't know if it uses activesync. I have set it to check emails every 30minutes.
wifi not turning off
Edit: I found the wifi sleep option in ICS. Google sure did a great job of hiding it. See attached picture for anyone else having wifi staying on during sleep issues.
So there are three options
Keep WiFi on during sleep
1) Always
2) Only when plugged in
3) Never
What option to set if i want Wifi to turn of after some time of when phone sleeps. Previously i had set the option to 15 minutes but that option is not available in ICS and i m having a hard time understanding how these options work on my sensation.
Can anyone explain what each of these options do ?

My guess:
1) Always: WIFI always on no matter awake or asleep
2) Only when plugged in: WIFI always on only when plugged to power
3) Never: WIFI will be off if asleep (my current setting)
That was it

Bear in mind that (irritatingly) applications can seemingly change this setting.

For an app to change wifi sleep policy, it needs the WRITE_SETTINGS permission.
Hi everyone
I just flashed Android Revolution ICS Rom and I'm quite happy with that so far ! The only thing I cannot find is how to automatically disable the wifi antenna when the screen goes off...
Any help would be much appreciated
You can try in wifi setting and set wifi sleep policy to "screen off" out you can get Auto Airport Mode by Dan

Well I just took a look. Guess they changed it a round a little
In Settings under the WiFi, click on More and there's an "Airplane Mode" try that.
Or try Auto Airplane Mode (this is what I use and it work great)
https://market.android.com/details?id=com.blogspot.donkun3.autoairplane&feature=search_result
hit menu (3 dots in top right) when you are in the wifi menu hit andvanced then hit "Keep wifi on during sleep" and change to only when plugged in or never

Wow... wouldn't have found it by myself
Thanks a lot !
I'm noticing the native setting for disableing wifi when sleeping is working poorly. It takes a while to turn it off and then when it restarts the service does not seminar to be able to obtain the IP address and I have to manually turn wifi off and then on again for it to obtain an address. Very strange because the auto airplane app has no such issues.
I have just found out that:
(under GB) "Advanced > Wifi Sleep Policy > when screen turns off"
is NOT the same as
(under ICS) "Advanced > Keep Wi-fi on during sleep > never (increase data usage)"
It is supposedly to be the same thing but it is not.
As osho741 observed, it takes a very long time to turn off and most of the time it just does not.
I think this is one of ICS bug.

It does turn off fine here after around 10 minutes but it takes at least 30 seconds to activate and connect.

Is there any specific reason youd want to turn off the wifi during sleep? In my experience it doesnt drain enough battery to bother turning it off.
In my case with wifi on and a few apps running that uses wifi all the time, the tablet drains around 15-20% over 12h while sleeping.
That gives at least 2.5 days batterylife if you keep it sleeping... I cant imagine you would have to have it turned on (sleeping) longer than that. In that case you could just shut it down completely when youre not using it
you should give juice defender a try. it revolves around battery optimization, but it isn't a task killer, it just lets you make whatever setting you want concerning turning off services like wifi, bluetooth, etc.. its highly customizable, so you can set it to turn the wifi off entirely while its asleep, or to keep it off, while turning on in whatever time increment you set, long enough.
i have mine set so that the wifi turns off and stays off entirely when its in sleep mode, but if i have a online radio app like pandora or 8tracks running, then they override the sleep settings, and keep the wifi on when the screen is off.or, when i use certain apps that don't need internet to run, like kindle or certain games, the wifi automatically turns off and remains off until i close the apps.
i really like it and i think its made a huge difference in battery. Before if used it, my transformer would drain 15-20% percent overnight with the wifi left on. now, it drains maybe 2-4%.
Turning off wifi during sleep makes a huge difference.
It really saves a lot of battery for me.
And juice defender, while it might help, but on my phone, it causes a lot of wakelocks.
You can check this with bbs.
I have noticed that even though I keep my Wi-Fi off 80% of the time, when I look at the built in "battery app" (whatever you wanna call it) it shows a blue bar all the way across for WiFi, which I believe means it's always on.
Also, sometimes WiFi usage will show up on the list of things eating the battery, and it will show that it's on the entire duration the phone has been turned on ,even though it shows off in settings.
Anyone else have this issue?

As posted in the thread now below this, check this out as It could be, Settings>wifi> menu Advanced and turn off scanning always available.
