Problems: Wifi keeps turning on and off when screen is off - Desire Q&A, Help & Troubleshooting

Hey there,
I'm using S-off and oxygen 2.2 on my rooted desire and I have a big problem:
Always when I press the power button so that the screen goes off and than turn it on again by pressing it again after some time (20 secs or so) I see that wlan is turned off and the cellular data connection is used. Shortly after the screen went on, WLAN is on again. Is this some default behaviour to save battery? Is wlan really more battery comsuming than the providers data connection?
The problem which arises now is: I'm using http://www.appbrain.com/app/unlock-at-home-using-wifi/com.accedo.unlockathome which unlocks in a certain wifi and locks, when going out of whitelisted wifi networks. When I press power to turn off the screen and the wlan is disconnected after some short time, the screen gets locked and somehow I think that the screen gets on shortly after this. This causes the wifi to connect again and than after turning off again the wifi gets disconnected again. Thus after the lock applications locks the screen and thus shows it again... -> infinite loop. every now and than (i think about once a minute) I see the screen go on and quickly after it off again.
how to fix that?

Do you have something like Juice Defender installed?

Check the sleep policy.
Swyped from Oxygen with Transparent XDA App

Set wifi sleep policy to never, under wifi advanced settings.

Nope i havent!
@k3lcior: strangely it's already set to never and though I often see the cellular data icon appear also when I use the phone (e.g. when writing an sms) and directly disappear again there's to be a problem I think with something on my phone!?

turn off WiFi?

guys, is there any point turning off WiFi when not in use, or does it do the decent thing and stop using power when not actively in use?

I'd imagine it still scans for networks so it will still use battery - I just have the toggle on one of my home screens and turn it on when needed

from Market, get WiFi Status from Andrew Schwimmer, one of the very best android app developers. It doesn't do exactly what you want but it's the smartest detection app out there for letting you know when there is no wifi signal to connect to, thus prompting you to toggle off wifi. It displays in the Notification Bar.
As for turning off wifi, I tried about 10 home screen widgets; they are all the same more or less. To me the far greater tool is Quick Settings, which gives you one-click access from anywhere via the Notification Bar, vs having to navigate to home screen and find the widget. But in addition it has toggles for sound, brightness, data, gps, bluetooth, etc -- all in on fast app.
I think it blows all these single-function widgets away as dumb.
So if my phone is on, screen off, in my pocket, it'll be constantly looking for wifi? If this is the case it's, well, dumb. Ta for tip about quick settings, just installed it and it's very nice.

Add the widget 'Power Control' for one-touch bluetooth/wifi/gps/sync/brightness control....

Not sure it would be scanning for wifi when the screen is off. That would be daft. Ntework coverage yes, but wouldnt think wifi until you turn on the screen. Anyone confirm?
no, it stays on when the screen is off.
Seems so many people complained about it turning off in standby that google went ahead and changed it.
now it defaults to staying on forever until manually turned off.
Go to Settings> Wireless & Networks > Wi-Fi Settings > [Menu] > Advanced > Wi-Fi sleep policy. I set mine to 'after 15 mins'... if I understood this setting correctly then after 15 minutes of the phone being in Sleep mode it'd turn off the Wi-Fi. I don't use mobile data anyway so that's irrelevant. Wi-Fi will turn on again once I activate the screen.
blimey, that's well hidden.
what a stupid arrangement. WiFi should be on demand, and enabled only when data requests it, like the iPhone.

I use "Y5 - Battery Saver" for my wireless shenanigans
I am using 'Y5 battery save'r. It turns on wifi if you are on a location where you had a wifi connection and turns it off if you go elsewhere. You can manage the locations in the program. It can use the GPS or radio for the locations. You will find it in the market place.

Is 3G data sleeping?

Hi,
This might be a dumb question.
On normal situation with Android phone:
When I turn on my device from sleep, I could not see the 3G icon ... Only the signal strength. Then after couple of seconds, the 3G icon came up.
My phone works like this since I have it.
My question, does this mean the 3G data is also sleep when the phone sleep? Because when I wake it up, the 3G icon does not immediately come back.
Thanks.
Yes, it does disconnect after a period of inactivity (if you look at the android logs) when the phone is in sleep mode. There is a setting which you may not have enabled. it goes on the lines of 'Enable always on mobile data' under wireless and network options.
However if the phone needs to connect to the net, then i think it will re-connect in that time period. This is what you see when the 3G icon appears after a few seconds on wake up. I have always seen the phone to do this.
Allright,
I was thinking if this kind of app is really necessary:
http://forum.xda-developers.com/showthread.php?p=7547017
But, I guess, it is useful because during the sleep mode, some app might require internet access (email sync for example).
Maybe....The only reason i say this is that the OS will start a new network connection in the background even when the phone is sleeping...thats how your emails are sync'd and so is everything else...

[Q] Where do I find WIFI sleep policy settings?

On ICS, where can I find the settings for Wifi sleep policy etc? My Wifi keeps turning itself off after a time, and Im trying to get the the bottom of it, but cant find where those settings would be. They certainly arent where they have been for previous Android versions...
Go to Wifi Networks, click menu bottom on bottom right > advanced.
Even though mine is set to always stay on, it regularly turns itself off. Every morning, I've lost quite a lot of battery and I have no connection. Within a few seconds of the screen coming back on, it will reconnect.
Is this just me? (Android Revolution HD 2.1.2)
Its not working for me. No matter what setting I put wifi on it turns itself off when out of range for a certain period of time (about thirty minutes I think). Driving me insane.
Mine's only a couple of meter's from the access point, still turns itself off...
The same for me. Not 30 minutes but immediately.
For example the notofications appear only if I unlock the screen.
In wifi setting is on "keep always"
Example: i receive a whatsapp, email or facebook notification only when unlock the screen. Is normal?
With data connection all work fine.
I'm glad to know it's not just me. At least that means hopefully there is a fix coming at some point...

same here anyone an idea? sucks hard..
I figured my problem, traced it back to the Vodafone app, it was causing wifi to crash. Once i removed it it works perfectly. The problem stemmed from the vodadone app constantly trying ro find free wifu points to.automatically connect to.

[Q] Wifi won't connect until turning on screen

My WiFi doesn't seem to connect to saved hotspots until the screen is turned on. Whenever I get to work or back home and I don't turn on my phone; a couple hours later when I actually turn on the screen it connects. Does anyone else have this issue or know what might cause it? I'm not using any power saving apps or any apps that affect my network.
Try going into Settings-> Wifi -> Click menu button and select "Advanced" and make sure "Keep Wi-Fi on during sleep" is set to always.

can anyone else verify this happens for them too? I have tried a complete format/wipe and loaded a stock 7105 rom and am still having the issue.
Maybe if you have power saver on, it does that? I know it's lot listed under what it's done, but you never know (;
Other than that, I can't think of anything other than keeping WiFi on during sleep.

it's off :< My roommate's S3 and my other roommate's N4 both auto connect without touching the phone. Once you turn the screen on it's already connected to wifi while mine is on edge until I power on the screen.
The only reason this is an issue is that I use grooveIP for calls through data, so if I have no reception here (i.e. no data) I won't be able to reliable receive calls unless I remember to power on my screen every time I come home.

No auto-connecting to wifi when BT connection lost

Hi there,
after update to MM i'm having following issue. My watch doesn't automatically connect to wifi network when i'm going out of the BT range. It will only connect when i wake up the screen and swipe down the top menu or slide left to the app drawer. It looks like you have to first wake up the watch to trigger the action.
Anyone having the same? It's quite annoying as it happens all the time in my home when i'm going between the floors without my phone with me. Of course, i have wifi adapters on both floors. so it's not a matter of wifi signal strength. As i said, when i "trigger" the reconnection, it will connect to wifi without problems.
Thanks in advance.
Having the same problem. Have had the watch 2 days. Anyone have a solution?

Nobody? I have also restored to defaults and configured once more but the issue still occurs. It starts to be very annoying.
a theory: it's in power save mode. Let it go below 15% battery, find the card about battery saver, turn it off. I think I've seen that power save mode stays on even after charging, and can only be turned off with the card.
Also check your settings under wifi/advanced
Thanks. I also tried to remove some saved wireless networks from the watch and it also helped a bit.
