WiFi doesn't reacquire from sleep. (stock/rooted)

Dunno if this is a common issue as I couldn't find any other mention of it.
Basically, if my O2X has been asleep for a while while I'm at home and I take it out of sleep, it doesn't automatically reconnect to my home network, even though it's set to "never sleep". I have to either disable and re-enable WiFi or leave network notifications on so I can establish the connection from the available networks list.
Has anyone else got this issue or know of a resolution for it?
At least while on MoDaCo Fr12 it seemed to reconnect more quickly but I'm getting 48 hours out of the battery back on stock so would rather start there.
Cheers

Same here. I'm rooted, got CWM but still at stock. It is either being rooted or the freezing of a certain app.

Mine is rooted and from the moment i push the lock button it already is connecting after 2 seconds. Problem could me an app.
What apps did you install that require a wifi connection ?

None really. Auto-sync is usually off and everything else is "on-demand".
Might try a full wipe and just re-install a few apps at a time with titanium.
Hmmmmm.

Hi,
Same prob here. Sometimes it reacts, sometimes it dont. And if it's stuck I have to reboot.

i have same settings, maybe a hardware fault ?
But try to wipe first and see what happens

try app, blade wifi fix from market you must be rooted

happens to my x10 as well sometimes. blade wifi fix does help a bit, although you can always activate/deactivate wifi manually but yes it is annoying.
try changing wifi sleep policy to never, it won't disconnect but you'll notice some battery drain.

This is a known issue with some access points. The G2X forum also has a thread about this.

[Q] Wifi & Mobile Data Issue (ICS)

Ever since upgrading to ATT ICS, my WiFi and Mobile Data connections both are turned on during the night. During the day, I don't run either. When I am at home, I use WiFi and then turn WiFi off and plug in the charger before I sleep. When I wake up in the morning, WiFi and Mobile Data are turned ON. This happens constantly for me.
The second thing I tried was not putting the phone on the charger for the night. Come the next morning, WiFi is ON but Mobile Data remained off.
Something is triggering WiFi and Mobile Data to automatically turn on. I can't seem to find the setting that is allowing this to happen.
With GB, I never had this issue. If I recall correctly, GB had a setting for the sleep period of the phone. I don't remember much else of what was adjustable in that menu and I can't remember if I set anything in there for GB and data. I cannot find anything remotely like that in ICS. ICS is bloody annoying me right now with these quirks.
I wish I could downgrade back to GB right now so I don't have to deal with data turning on during the course of the night.......

If you want to go back to gb look under the development tab for return to GB from ics. It's down a ways. Not sure what to tell you about the other issues but to try and reflash ics.

Try Airplane Mode
Sounds like you have some app trying to make a connection to run an update. It's turning on WiFi and/or the Mobile Data connections. I'll check mine tonight to see what happens.
Try turning on the Airplane mode when you go to bed. Hold down the power button and select the Airplane Mode option. If that doesn't keep the radios off, something is really wrong.
I sometimes use the Airplane mode at night to conserve the battery, but since you're charging, that's not an issue.

I found the thread. Thanks. I just need to read about unlocking the bootloader now before proceeding. The only downside of downgrading is I will lose the ICS radio which is giving me such good signal strength. Before in my room at home, I would get 1 bar, now I get 2 or 3. LULz.

This happened since day 1 of upgrading to ICS. The only software that I installed were some games and utilities that I had on GB. I never had an issue with either data connection turning on.
I might try another flash of ICS but that would mean running it for a night without the downloaded software for a couple nights and then installing each one by one, night by night.
I can use airplane mode but not for long term. I need to be able to receive calls from work when issues arise during the 2nd and 3rd shifts.
This only happens at night. It never happens during the day which makes me believe something is happening during the phone sleep time. And there's no setting that I can find for the phone sleep time like GB. Grr.....

Why not just leave data on if u don't mind me asking. Can't be using that much data really

Yep I have the same issue.
I have observed the data icon appear on the stroke of midnight. It takes three attempts to keep it off till the next time I use it, or when the damn thing turns back on at 23:59:59.
Spoke to HTC support, they advised to return it to retailer for them to examine it....WTF...lol

We have two threads on this issue of WiFi and/or Data turning on at midnight. When I first found the missing voice dialer problem, I e-mailed HTC support. They responded to my e-mail and then a member of their escalation team called me. They recognize that this is an ICS upgrade issue. Of course, they don't know when it will be fixed.
If you have not already done so, log into HTC.com, go to Support and send an e-mail describing the problem. They need as much feedback as we can give them to get HTC and/or Google to fix these problems.
I am not surprised that the ICS upgrade broke some things, but the number of things surprises me.

Check your setting. Drop the drop bar and enable Wi-Fi connection then touch the bar next to the off-on switch. Touch the icon next to the home icon on the bottom of the phone and click on advanced. See the screen shots.

Too bad. I noticed mine came on the first night after I installed ICS. Took awhile to find the settings I posted. When I found the settings and clicked on the one in the picture I never noticed Wi-Fi come on on its own since.

So I finally got around to trying Airplane mode. WiFi still kicks on overnight while plugged in.
vivid x2 - I had that checked to "Never" and I still have WiFi and Mobile Data coming on at night.
brucegil & FPV-GT - I will submit a support email ticket. I'm surprised there aren't more of us on here that are having this issue.
syrkel - I don't want either WiFi or Mobile Data on. If I'm not using it, why have it activated? All I need during the night is 2G voice so I can respond to work issues that may arise.

Just throwing another thing to look into. Try to reset the data counter and check it every few hours to see what apps are using the wi-fi data? Some of the apps even allow you to access the app settings from there as well. Check some of the app permissions and try disabling a few apps at a time that allow changes to wi-fi settings.

what a coincidence. i was just jacking around on my phone in class and found the advanced wifi option and there is a setting to keep wifi on during sleep. it has three options: always, only when plugged in, and never. hope this helps

Try installing a juice defender. It turns off data when your screen is off automatically. Also, (maybe only in the paid versions) you can set a night schedule for it to disable connectivity for a set time automatically. I have mine disable all data connections and go to silent mode from 12:30 to 8:30.

I tested this last night. Before I went to bed, I turned off WiFi (Data remained on). On the WiFi advanced settings I had the Keep Wi-Fi on During Sleep setting to "Always," which is the opposite of what people here have mentioned. I plugged in the charger. However, I have my Vivid set to remain on while on the charger. So it technically never went to sleep. (Makes a nice night light.) At 2:30 a.m. when I woke up, the WiFi was not on.
Tonight I will keep the same settings, but I will not put it on the charger (I'm testing the 3400 mAh Mugen extended battery). I will see if the WiFi comes on during the night.

I wonder if this is part of Googles data collection. I have gone through 3 vivid phones in the last 2 weeks (long story). I have seen this problem happen with no apps other than what came with the phone. My wifes phone (another vivid) does the same thing. If the phone is turned off for the night, turning the phone back on has the same results (mobile data is on). This seems to be a random problem.
When you allow Google's locaton service part of the message says that you are allowing Google to collect data even when no apps are running.
Just a thought.

I've been trying to figure out what's causing it...see my last couple posts here.

wifi issues with ics

Hey, my wifi always goes out and needs to be restarted while using ICS. at first it would happen like three times a day. now its a couple itmes an hour. it is very very very annoying. does anyone know a fix for this???

I don't have this problem, but do you have a wifi-sleep timer set up? Maybe an app is doing something?

No i dont. This issue was posted before in the threads but never had a solution. I always wipe EVERYTHING so i dont know why this happens with me.
Sent from my XT862 using Tapatalk

It's not just you. I get MANY wifi drops as well. I don't use it often, but when I do, I get a drop every 15 minutes or so. It happens very randomly: as in not when I'm loading a page, just randomly I'll see the logo go white then disappear.
My solution? A frustrated sigh and a switch of wifi on and off.

I did no have this problem on the AOKP 4/12 build, but do have it now on the 4/30 build. No idea why.

The audio issue is also ALOT worse for me. most of my phone calls do the silence thing where there is no audio. Today it caused me to run into alot of trouble. i hope these issues get fixed soon. I think it was the bluetooth updates in the changelog that caused the problems to occur more. As they are supposed to be bluetooth related. Unforunately i might have to go back to gingerbread

I am able to use 1x data & WIFI on ICS Rom only. Neither WiFi or Data works with Stock ROM.
Before It used to work in Stock ROM, but now it does not. So I am sticking to CM9

I have this issue too but I use juice defender. I only really use it for 2 functions
1. Enable WiFi when I'm home (constantly on) and disable when I'm away
2. Turn off data at night from 1am to 6am
when i flashed ICS the effectiveness is shady. A lot of times when i turn on the screen wifi is disabled but will reenable after a few seconds during the day. also at night sometimes it won't disable until later than 1am and will randomly enable and disable at like 4 am or something. sucks because i'll randomly get a bunch of notifications for emails twitter etc. and it will wake me up.

nexus 7 not killing wifi during sleep after updating to 4.2.1

I have selected to never keep WiFi on during sleep yet now the tablet continues to run the WiFi as you can see in the pictures. This has forced me to use airplane mode when I am on the go because otherwise the tablet just keeps WiFi on and burns the battery extremely quick. This has been a problem since I updated to 4.2.1. I am not rooted completely stock. A solution would be great because this sucks right now. I have tried clearing the cache in recovery but that didn't solve the problem.

I'm running the latest Paranoidandroid ROM and thought that was the problem. I can't yet post to that developer forum so I was just waiting for the next beta.
I guess it's a problem with 4.2.1 then.

If you don't find a solution you may want to try DataEasyPro from the market. It kills both 3g and wifi as soon as the screen is off and then runs a user defined schedule to turn on 3g or wifi every now and the for a few seconds to keep you upto date with your social world. Works great. There is even a widget so you can turn off the schedule when you are downloading or updating from the play store.

I think it is a 4.2.1 problem. Its hard to say how wide spread it is though because I have only seen a handful of posts about this issue though. To me, this issue is unacceptable. I should not have to enable/disable airplane mode to conserve battery. Especially when the previous version of android prior to the 4.2.1 update handled WiFi sleep settings without a problem. Hopefully a fix will be here soon. My tablet used to have superb battery life without me constantly monitoring it. Now I feel like I have to keep double checking that I remember to use airplane mode so that I don't go to use the tablet and find a nearly depleted battery.

I recommend automate it, I have a couple of rules set to turn WiFi of with the screen (with a 5min delay), then turn Wi-Fi back on when the screen turns on. There's plenty of other settings and rules to play with as well.

In had the same issue. I found Google maps to be the culprit.
It defaulted back to location reporting.
Check Google now sync, maps and currents.
Sent from my Nexus 7 using xda app-developers app

It's not google maps itself, it's the android location service. It's always collecting data even if your phone or tabscreen isn't on. This is pretty anoying since google only let you choose between agreeing to run the service in the background or not using it at all. Stupid! How about collecting data only when the device is in use?

Same here. There is a bug report on Google about it.

what is the OP using? Are there any apps installed/running on the OPs device that can keep the WiFi alive?

I highly recommend using an app called Better Battery Stats. You can find the free version here on XDA. It'll tell you if there is an app causing a wakelock. I used it to troubleshoot my Rezound and I'm getting a solid 4-5 hours of screen on time with the extended battery on that because it helped me lock down the apps that were killing my battery.

I was having the wifi on issue as well. Just bought my N7, stock 4.2.1 and not rooted. I followed the tip in point four of this post, which details a simple set up using Tasker, where the unit turns the wifi on and off after the screen turns on or off respectively. The reason for the 10 second delay as is detailed in the link, is to allow for the turning on of your N7 to check the time or other reasons, and then quickly turn it off without the wifi on task being activated.
the screenshot below shows my wifi being stuck on while in sleep mode, even with it set to be never on during sleep in the settings, and the change in behavior once the 2 Tasker profiles we set up.
Cheers

Those of you having issues, have you tried the "only when plugged in" setting? Not sure if it would really matter but that's what I use and mine turns on and off just fine.

Testing that now. Turned off Tasker, and set wifi to the "only when plugged in" setting. It's only been about 30 minutes, but so far it looks like it's behaving the same as before, as in keeping wifi on while in sleep. I'll Let it sleep for a few hours and see what the chart shows.
Cheers
EDIT: So I let my N7 sit for about an hour after switching the above mentioned settings, and you can see in the screenshot below that the wifi is staying on while the unit is not awake. I've set my Tasker profiles to control the wifi once again.
I know it may be fixed by a factory reset, but frankly I'm more than happy with the way Tasker handles the issue.
Cheers

so 6 months later, I am still getting this problem. However it seems only to be with the last update. The tasker method seems to be working well though.

Stock ICS Bugs

Does anyone else think this update was half baked?
I'm having a lot of issues with the new update. Bluetooth keeps skipping like a scratched cd, Wifi won't connect just keeps requesting ip from router then I have to shut off wifi and turn it on manual to connect, I really need to fix these problem any suggestions.
Can I roll back to 2.3 stock some how?
Are there any other good forums for this phone?

I love it. No problems with Wi-Fi. As a matter of fact, to get Wi-Fi to work in gb,I had to reboot the phone everyday. Also no ghost calls. Being able to turn off data and Wi-Fi manually gives me 2 days of battery life.
