Quick test for those that are having high battery drain due to the newest firmware release, with lots of usage being attributed to wifi...
If you have the wifi sleep policy set to never (Settings, Wifi, Advanced Wifi, Keep Wi-Fi on during sleep = Never), if you turn off the prime, can you still ping the IP address listed that's assigned to the prime when it's in sleep mode?
If I set it to sleep / close the dock, wait 5 mins or so, then ping it's IP address, I get a few timeouts then it starts responding...
If I start pinging it when it's awake, I get ~250ms pings, if I sleep the prime it times out a few times then the ping jumps to 700ms odd...
To me - this indicates that the wifi's not sleeping properly, when you sleep the prime it should stop responding entirely...
Does anyone else get this?
I've never had a wi-fi battery problem issue so far.
But there a setting in Asus Customized Settings, all the way down 'Disconnect Network during Sleep'
it at the very least logs you off Skype and doesn't sync/receive emails when you close the lid on with the dock.
Cheers

Correct.. but 21 increased battery drain, probably because of changes in WiFi power. They wanted to fix the weaker reception, many are experiencing.
Otherwise, you suggestions are very good.
There is another thread about it...

Under settings/wifi/advanced, I have "keep wifi on during sleep" set to always. Yet after being off for a while, wifi seems to turn off. That is, upon waking phone from sleep, I can see it reconnecting to wifi, THEN my email is downloaded (k9 set to imap push). This indicates the above setting is not being respected.
Under "settings/more/usage/mobile network" is also set to on. This would suggest that even when wifi is not available, 3g/4g would still be used. This also does not seem to be the case. When waking the phone from sleep, I can see it reconnecting to 3g, then immediately connecting to wifi.
The goal is to have data enabled, even when the phone is sleeping so email can be received. The old evo 4g had a setting to keep data on even when phone was asleep.
Suggestions?

When i downloading torrents using my android phone over the WiFi, its connection lost several times. My phone WiFi policy is "Keep WI-Fi on during sleep" as "Always". I use "Ttorrent" app client. Most of the time Ttorrent display "No suitable network" error. If i turn on the screen, problem not fix.
I have android 4.0.3 ROM and i connected my phone into my ADSL router, not a public.
Are there any solution for me?
Thanks!
Did you rule out the signal strength and wifi network quality? It might just be that the connection is flaky. One way to test is just sitting close to the access point or.. to change it to a different channel (when you suspect interference from neighbor routers is the issue)

Thanks friend your reply!
If I move my phone close to the router, its not fix. Also its possible affect, my neighbors Wi-Fi connections (because of the distance of neighbor houses, to my place). Is it a effect of my router settings?

Is there an option in your client to lower the maximum number of connections? That's a recommendation from the developers of adownloader, which is what I use
I am having the same problem.
I've tried so many things, on the phone and router.
Nothing has solved it.
I've adjusted a lot of settings on the router which have made no difference, I've used different types of security, wep, wpa, wpa2, no security at all. Static ip, changed dhcp lease times etc
On the phone I've tried setting a static ip, flashing different kernels, using different torrent clients, lowering number of global connections to 1 etc
I've also tried a few apps from the play store, wifi fix, wifi static etc
The wifi will just randomly disconnect when I download any torrent, there is no pattern to it but I can't download any torrent without disconnecting.
I would love to know a fix.
I'm using a galaxy s3
One thing I want to try is a different router to rule out whether the problem is the router side or the phone side.
At the minute I have no idea what is causing the issue.
I don't get disconnected when browsing the web etc on my phone.
If I use my pc or laptop to download torrents I don't get disconneted.
Ok I've finally worked out why I was getting drop outs.
For some reason when I use wpa2 with aes ecryption I get disconnected when downloading torrents.
When I use wpa and tkip I get no disconnects at all.
It's not a good solution as I get slower speeds using wpa and tkip but at least I don't get disconnected.
I wonder if this will be fixed?
This is an ICS bug. No matter what you have your wi-fi sleep policy set to, when the screen goes off the performance drops drastically. Download the Wi-Fi High Performance Widget from the market. When tap to enable the widget, your wi-fi will run at 100% performance no matter your screen state.
This isn't a sleep issue though. I have wifi set to always on keep wifi on during sleep.
Even the op said he tried leaving the screen on.
I set screen timeout to 10 minutes so I can monitor the application and also set screen on within adownloader and I get disconnected.
The only fix for me is using wpa and tkip encryption.
As soon as I use wpa2 and aes encryption I get disconnections when downloading.

Well, probably a hardware issue. I have no issues using the same wifi configuration and downloading torrents. And like I said..it really doesn't matter if you have keep wi-fi on during sleep checked. That doesn't matter at all. The performance will degrade so much when the phone is asleep that you might as well have it turned off. No, your wi-fi won't sleep, but it won't be running anywhere near its top performance, which is what the widget is for.
Wow. I have been trying to solve the same problem for last 2 weeks. upgraded windows drivers, router firmware, tweaked utorrent settings and whatnot. finally after reading your answer i changed my wifi authentication from wpa2+aes to wpa+TKIP and WOW. it worked. my wifi is not dropping anymore. I dont why WPA2+AES should cause this problem. BUt this tweak in authentication has finally worked for me.
My wifi connection often wrong, always in after a period of using, have no access to the Internet. Every time the wifi turned off to open another can get to the Internet, can wifi signal is always full. I searched a lot of method to did not solve, including XDA * # # 0011 turn off on wifi power save mode, when problem solving, but after a while just the same. And with only G mode and so on route, are not solutions. Change a lot of Rom, the kernel baseband all not line.Who's a way to solve?
I am not sure if this is the case but - have you tried different router? My S3 for example has issues when I go to my friend's house (he has some old/er Belkin router). However, when I am home wifi is blazing fast and no issues what so ever (cisco e3000).
my phone has a slight different problem, the phone detects strong signal for all my wifi, but will only save it, and not connect right away, some will not even connect, and sometime the speed is very slow.

I am sure there is no porblem with the router,SGS2 and IP4s with the same router is fine.
I'm getting WIFI problems when waking from deep sleep. My settings are set to keep WIFI on when sleeping only when plugged in, as i find this extends my battery life a little more.
Sometimes it reconnects when waking up, and other times it doesn't and i have to turn WIFI off and then on again to force it to scan and reconnect. If i don't do this and check WIFI, it says it's scanning, but never finds or connects to a network.
Anyone else get this?! I read somewhere about sleep of death on GS2?
There is a known problem with the wifi, I have just changed my phone and so far evrything is working.
been through 9-10 phone with different problems.
Ok, i've tried turning off WIFI power save in the system settings *#0011#
I'll report back with my findings in terms of waking from sleep and possible additional battery drain...
Turning off powersave didn't help on my speeds tho. My SGS2 can pull around 5-600KBs a second, while my SGS3 only pulls roughly half despite being at the roughly same location (ie laying next to each other)
Will toggling Wi-Fi on and off drain your battery? I'm asking this because I read:
http://www.androidcentral.com/android-101-save-battery-keeping-wifi-alive
Essentially, you want your Wi-Fi sleep policy to be "Never" because when the Wi-Fi sleep policy is "Always," your phone searches for Wi-Fi more often and that drains battery (I think that's what it is saying).
At the moment, I toggle the W-Fi on every time I'm using it and off as soon as I'm done using it in an attempt to save battery. I'm not sure if this actually works or it's actually draining my battery because it would search for Wi-Fi every time I toggle it on.
On my Samsung Galaxy S4, I can't find Wi-Fi sleep policy as mentioned in the article, but I found "Keep Wi-Fi on during sleep." Am I supposed to set this setting as "Always" to save battery life?
Thanks.
P.S.
I toggle Air View and Smart Gestures on a frequent basis as well--not sure if I should do that too.
keep wifi during sleep-always will drain your battery as even if u don't use your phone wifi will be still on
I'm wondering about my new android tablet me176c's wifi stability.
It connected to my router(IPTime N604T, from Korea) all day very well.
But, sometimes it occurs that despite well connected and has good signal strength, no internet access IN APPs at all !!
About one time a day this happens. very annoying
Then scroll down from above, turn off Wifi, and turn on Wifi again, it goes fine.
During these days I found that it often appears on viewing YouTube video.
I changed wifi connection to Static IP Address, turned off any battery saving options in wifi settings.....not solved.
My another tablet TN7 doesn't have symptom like this.
Any advice will be appreciated. :good:
