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.

Trying to Stop Cell Standby

So I was looking at the settings.db with the sql3 lite editor and came across this: Line 59 mobile_data value 1. However, I'm constantly in airplane mode and only turn on wifi and bluetooth as needed.
Is it possible that this line is the controlling factor to keep the Streak from turning on the mobile radio? Would setting this to value=0 stop cell standby?
I'm a little afraid to tamper with it since I don't know what it means - does anyone more knowledgeable than I know what this line controls?

A app called juice defender offers that option

Not actually - I installed juice defender but mobile_data still has a value of 1. And cell standby still is showing at 88%!!!

I also had this huge battery drain to cell standby (on the wifi only model...)
trying to flash the Honeystreak, and see if this changes (and to try out HC too hehe!)

Okay, that makes sense. I was using that for awhile on the stock, and noticed no difference. Uninstalled it a week later.
Will try to test it out on streakdroid once I get back onto a working rom (fell into the BSOD of Honeystreak B3)

Just keep airplane mode (Setttings>Wireless) on all the time - no need to ever turn it off since there really is no phone in this tablet.

That doesn't stop the phone modem. If you check the settings you will see that the device is still picking up signal from the cell towers. It just isn't connecting with the mobile network.

I don't think that is doing anything more than the existing settings. The S7 already allows one to turn on WiFi during airplane mode. Earlier android versions did not allow this.

I finally was able to disable "cell standby" by the following procedure (for reference see the following in the Acer Iconia 500 forum: http://forum.xda-developers.com/show...t=cell+standby )
Using "Bloat Freezer" freeze phone.apk (the instant this is done, it will force close - just hold the power button until it shuts off ) - this will only happen once. Then using "Bloat Freezer" freeze telephony.providers.apk - this doesn't force close. Reboot once more and viola! no more cell standby. I also noticed in the notification area at the top a new icon - it's 4 bars with an x over the lowest bar. It's like when you turn a cellphone on airplane mode - same type of icon.
Also, I had airplane mode enabled (I always have that) and now the little airplane no longer shows up - I guess it's been replaced by the "bars with x" icon. WiFi still works as well as it did before.
To me, this indicates that mobile data is off but maybe someone more knowledgable can give a better explanation.

[Mini 2 GT-S6500] Reboots caused by wifi

No-one appears to have had this issue on this phone yet, and not for this exact reason, which makes me think it's only a small error somewhere. (I hope)
Ever since I got it about a month ago, even before I rooted it or did anything to it, it would randomly reboot with no particular pattern. I've since discovered it's specifically caused by the wifi being left on, and the phone left locked for more than about 15 minutes, regardless of whether any apps are open at all. All in all it only happens when wifi is on, and it's not charging or being used. When being used it never happens, and when it's plugged into USB or the wall charger it never happens, and never when just network data is on, no wifi. And I can leave it with both wifi and data off and it will happily standby for it's whole battery life with no issues.
What is the wifi doing when I leave it locked? does anyone know specifically why it causes this?

Anyone? I use wifi way way more than my data, i want to be able to put it down for 10 minutes!

Try updating the firmware. This might help...
Sent via XDA Premium

There may be a corrupted apk somewhere that would be active only when Wi-Fi is on (note that there are some services that are still running in the background even if you think they are none , they are not that easy to find and will most likely restart if you kill them , but it's ok because they need to run) . Reflashing the stock firmware with Odin should do the trick.
Also I presume you haven't overclocked it . If you did , lower down the max frequency a little .
FInally , are there any heating issuses when this happens ?

i've had the same issue with the mini 1. it was gone after i have flashed the stock firmware on it.
my mini 2 has no reboot problems (yet).

Try setting wifi sleep policy to "never" of you have at option in settings>wifi>advanced.
Alternatively, it could be called keep wifi on during sleep, turn it to "always"

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.

Ah this is interesting; as last night my battery was on 53% and I am sure I charged it fully previously...... Am on stock too but have rooted.

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.

[Q] With Stamina mode on, what do I set WiFi as?

Hey guys, apologies if this has already been queried, I look around first and couldnt find another thread about it, just similar topics.
I recently got the Xperia Z and I've got the Stamina mode turned on. As I have unlimited data, I always leave my data turned on and I have switched on the the location based WIFI so that my phone can auto switch to WIFI when Im somewhere that I have successfully connected to before.
My question is though, to get the benefit of all this battery saving modes, in the WIFI settings where it says 'Keep on during sleep' should I turn that to 'Only when plugged in/Never' or can I leave it set as 'Always' cause of having Stamina mode on? Or does the Stamina mode only turn my mobile data on/off?
Thanks for any and all help guy.

For my device, the Wifi setting bypasses the Stamina mode...if you really want to save power...put the wifi on never setting.

Thanks chefnoob,
when you say bypass, you mean that it doesn't turn off WiFi for your device, only mobile data? Sorry to sound like such a noob. I have set it to 'Only when plugged in' as whenever its plugged in, it is charging, so I don't worry about power saving during this time.
Have you, or anyone else, come across problems with Whatsapp being a huge battery drain? Stamina mode had notified me that Whatsapp was preventing it from fully working, but it was only when i finally decided to check in my battery usage that i realized it was using as much as 75% of my battery :/. Tried force stopping it, but then It stops you from receiving messages until you decide to open the app again.
I am hoping that it gets fixed in an update soon, if not I may have to uninstall.
Thanks again. Gaz

You'll save more power by keeping your wifi always on.

I beg to differ.

mengsuan - But that would mean all the time my phone is locked it will still be connected/trying to connect to WiFi, where as if I have my WiFi set to one of the other two, like the mobile data in stamina mode, it will be temporarily turned off until unlock my phone again. Surely the latter would be more power saving, having mobile and WiFi disable themselves whenever the device goes into sleep?

Yes, that is correct...
Also, if you set WiFi to "always" and you are not connected to a network, it uses up more power to seek for networks...
With your whatsapp problem, I think you have a conflict happening...
Maybe you got the whatsapp set to sync regularly while you have stamina mode on. What happens is, whatsapp tries to connect/sync but it cant due to stamina mode. Try this work around...
If you want to keep using whatsapp, add it to the exemption list in stamina mode. That way, it wont block it.
If you dont really need whatsapp, just disable it...you'll save more power using the latter.

Oh right, thanks chefnoob
In regards to the WiFi, I have set it to 'Only when plugged in' as I dont mind it being on more whilst my device is charging. When I unlock my device and I'm in range of one of my 'location based Wifi'' spots, it doesn't take very long to connect so that I can use that rather than mobile data.
As for Whatsapp, I don't really use it a huge amount, but I'm not fully decided on whether I want to uninstall yet haha, so my 'kind of' fix for now is to go on to read/reply to a message from someone, then if I expect a quick reply back leave it for a few minutes, if not I just force stop the app and check it again later on. A tedious job just to use an app, i know, but at the moment its my main method of contact with one of my friends, so I will need to find a new way before uninstalling.
Thanks anyway though, to you all, for help in answering my question and clearing it all up for me
