Wifi disconnecting - Galaxy S III Q&A, Help & Troubleshooting

Is anyone else having problems with the S3 not staying connected to wifi? Mine usually disconnects when it goes into sleep mode. When I turn on the screen it comes back on again. I'm running Wanam Lite 6.2 (DLJ4)

What sleep policy have you got it set too?
(Settings/Wi-Fi/menu button/advanced)

I'm the same even with the sleep policy set to wifi never sleeps. . Constantly having wifi disconnect issues with this darn phone.

Try different security on router

Try this, on phone pad click *#0011# this takes you into service mode. click menu then click wifi this brings up a screen with info on it. There is a box which says on. press this so it says off then click done. Your wifi will stay connected until you shut the phone down. When you restart your phone go through the process again. A pain I know but it works.

Thanks colin, I've heard this before and helps somewhat with the sleeping wifi, but not with random disconnects/reconnects, ive been creating lots of threads tryna solve my issue, may return my handset
Cheers

I've got "keep wifi on during sleep" set to "Always". Have also used *#0011# to turn off wifi power save mode, but it still turns off the wifi radio.

Turning PSM off works for my however the battery drains upto 5 times faster! So much so it's better to just manually keep reconnecting rather than turning PSM off. Is there a someway of tweaking PSM to not disconnect?

[Q] wifi turns off on standby/screen off?

Maybe I just recently noticed, but i cant remember it doing this before:
does everyones tab turn its wifi off when it goes on "standby" ie: the screen turns off? I don't remember it doing this before, i am stock, unrooted.
Everytime i press the power button to see the time or to do something, i notice that at the bottom tray it says no internet connection, but almost as quickly as I slide to unlock my wifi is restored. I have my tab next to me most of the day while I work on my computer, and rely on it to use gtalk, but if it turns wifi off, then I don't get notifications
is there a setting that i have checked or something? I have power saver off.
thank!
Go into your wifi settings, then go into wifi sleep policy, you can change it in there, having the wifi sleep with the screen off will save battery though, so unless you need constant updates or polling for apps I would leave it the way it is
thanks man, didn't see that setting. I am usally plugged in durign the day so setting it to never when pluggin in is exactly what i was looking for.

Glad to help

WiFi will not stay on.

I have to constantly toggle Wifi on and off all the time. I know it is a known issue but is it as common as mine is? Is there any fix to this? I hope it is a priority of CM7 developers cause it is making android on the touchpad pointless.
LoL, I tried to post this but guess what? Wifi off again. Here we go...

Yes everyone experiences this quite often... its why is is a known issue. Its also why so many threads on the issue exist. Its also why its in the Common issues and problems thread at the VERY top. People wouldn't have so much emphasis on it if it wasn't common.
Make sure you set your Wifi Sleep policy in Wifi advanced settings to NEVER.
The problem I am having is that I can connect to a network. Says the normal optaining ip address, then it says connected, but I have no internet connection. I do have internet connection on multiple devices running on the same network. Did I miss something in the settings for wifi? Thank you
This guy also suggests changing the hostname to something more palatable to some routers:

Not sure if it'll help, but I've made this change myself. We'll see...
I'm running Android without any problem with WiFi, but, I do run Regpon to keep it "alive".
It may help unless you are talking about problems with Webos!
Wifi is basically useless to me on Android. It will work for a couple minutes, crap out, say it's connected yet provide no connection, etc. I'm just going to stop worrying about it until an update is out.

I had WiFi working for a bit after first installing CM7, but after it went to sleep' I can't reconnect. I get force closes when I try editing WiFi settings. I've tried rebooting multiple times, toggling wifi on and off, airplane mode on and off, etc. It refuses to reconnect. It shows "connecting” briefly, but never actually does.
Can't do much of anything with no wifi... It was great while it lasted though.
Search is your friend people..... Known issue but there is a temp fix you need to do once and you will be fine until the next time you reboot. Leaving wifi on, press your network and tell your tp to forget it. Now turn wifi off. Turn back on, select your network, enter key and you are good to go until you reboot. Easy fix.
If wii settings is running real slow, no worries, do above steps pressing buttons only once and wait, it will catch up. If you pop up says it is not responding, click wait, it will work. Remember you only have to do this on reboots.

Thanks, but it also doesn't work for me. I had already searched, found that method (aside from already thinking of it and attempting it myself), but I get force closes every time and clicking wait doesn't help. It never allows me to click "Forget Network". It just cycles through Force Close when I try to get the menu to pop up allowing me to click on "Forget Network".
I downloaded an app called softlocker and it keeps the unit from going to sleep in all ways. I have noticed a huge improvement
We are clearly talking about 2 different problems here.
1) The known issue where WiFi is rock solid whilst using the touchpad, but if you let it go into deep sleep it will turn off and not come back until the wifi is cycled
2) This guys problem where he is randomly being disconnected whilst using his pad. I recommend getting the latest firmware update for your home router and also "temporarily" turn off all WiFi security connect your pad and see how it reacts, just to make sure this is not a security issue.
My Wifi crapped out a couple times last night. I was playing with Airplane Mode. After turning off Airplane Mode it works flawlessly again.
If it keeps searching / obtaining ip, put in the correct password.
I seem to have fixed the issue by changing my router from WPA to WEP security. Haven't dropped my connection in over 24 hours. Perfect.
Edit: 48 hours now, never dropped wifi.

Internet stops working with WiFi?

Hey everyone, I seem to be having issues when using wifi. When home I try to use wifi and it connects and seems to be working fine. After a while when sitting idle everything will just stops working. The phone itself seems fine, but i'll stop getting email and anything that uses internet stops working as well. To get things to start working I have to either toggle wifi or just turn wifi off.
Any ideas?
Check your battery/sync settings. If you changed to normal sync/wifi/etc will turn off after 15 minutes unless you manually change it.
Even at Performance power setting, I found my Wi-Fi would still go to "sleep" after sitting for a while. The culprit I think is the "Sleep Mode", which is enabled by default. Changing that to manual or even off should solve the problem.

You have to go to Advanced under WiFi Settings (Hit menu button) and turn always on.
Mine has the same "problem." I'm ok with WiFi turning off to save battery. I haven't been able to reliably get it to wake up.

Good call, man. I think that's why mine randomly shuts off too! Im gonna start setting sleep mode for when I sleep every night.... It says it shuts off networks when screen is off but when I turn it on, WiFi is on right away...when you turn WiFi off it takes much longer than that to power up so I don't know what networks its shutting down lol

WiFi disconnecting when screen is off

I'm trying to figure out if my Edge is bad. When I turn the screen off, and come back to the phone a few minutes later, I'll get a notification stating it has connnected to my router. I've checked the settings and it states the wifi is set to be always on. I attempted a factory reset and still no luck. Sometimes it'll take a few moments before it even connects to the wifi again upon turning the screen on.
Do I have a bad phone?

I would check under the advanced settings for wifi, there's an option for what to do with wifi during sleep. That may be your problem.
I've already checked and it''s enabled.

I have the same thing happening. I noticed when I was backing pics on one drive
. It would always say that back up has stopped because there was no WiFi After turning the screen on again.
I just got my Edge yesterday, and I am having the same problem with wifi AND also that it stops seeing any wifi and I have to toggle it off and back on manually THEN it will instantly connect to my known network.
Dear @vaxick,
Dial *#0011# and click on more>>WiFi>>"WIFI Power save mode" try to disable this option and see what happens.
*it might drain your battery faster.

Thank you for this suggestion, unfortunately it had no effect as I have observed the same wireless disconnect behavior now with both the WiFi power save both on and off. Once the wireless disconnects it no longer see ANY wireless networks no matter where I go until I toggle the wireless off then back on again. Then it will see all wireless network present around me and instantly connect if there are any of my saved networks present. At this point I believe it is either a hardware or worse a software problem with my phone, but I am really at a loss to the exact nature of this issue.
Mine also has this issue when connected to 5GHZ SSID. Connecting to my 2.4GHZ SSID solves this problem completely for me

I hope that this is a hardware issue with my phone, as your "solution" is totally unacceptable for me, especially since my work place has bandsteering AP's that use the same SSID's for both 2.4 and 5GHz.

Yeah, i have to turn WIFI off whilst at work for the same reason. Certainly hoping it's just a software bug and will be fixed quickly as it is by no means an ideal workaround
I also see this kind of problem since last 1 week, here is how i noticed. i user viber messaging app and it shows status online if you are connected. Lot of my friends started complaining that my status is not continuously online and fluctuating so i started doing tests.
Moment my display turns off i started counter and in 10 minutes my status changes as last seen and whenever i open viber app again i am online.
second test: i tried doing the same with whatsapp and connected at web.whatsapp.com and same thing happens within 10 mins i see yellow bar appearing that my phone is disconnected so again i have to open whatsapp on phone to reconnect.
this is very annoying to see this kind of problem on new phones, especially when old phones are working flawless.
Kind of the same problem, but with GPS. Once I disabled the battery saver mode, it stopped disconnecting. Have you tried that?
Are you referring to power saving mode in battery settings. i did check and they are turned off. No idea what else i am missing here.
I tried re-installing viber but still after 10 mins its keep disconnecting.

I'm having the same issue on my regular non edge s6. This settings is not doing anything have it on always still always drops the wifi when going to sleep. Its driving me crazy no idea why its doing this
i did check and i have Keep WiFi on during sleep >> Always option but still drops, no clue whats wrong with my phone.
I had the same issue and solved it by changing my routers security from WPA2/Mixed Mode to WPA2 Personal. Since this change, it works fine on both 2.4 ghz and 5 ghz.

I received my Galaxy S 6 edge a week ago and I am having this same peculiar reconnecting issue to WiFi that has been described here.
Solution?
I was having this same issue and was unable to find any good solutions for it online, but eventually found something for me that worked through experimenting:
Find the above mentioned "Keep Wi-Fi on during sleep" option (which is probably set to "Always" already), change it to "Never", and then change it back to "Always". Since doing this I haven't had it disconnect from the wi-fi once, where as before it would do it everytime the screen had been off for a few minutes.
The problem started happening sometime after I played with power saver mode, so I think it might be related to that. I know that the software has some other bugs related to power saving mode, as I had a previous problem where my softkeys stopped vibrating or lighting up, which ended up being related to not exiting ultra power saving mode correctly and was fixed by going re-enabling ultra power saving mode and exiting again.

Issue with WiFi turning off. Anyone else has this issue?

Hi Guys,
I am facing a problem with the WiFi staying on on my brand new xz1.
In the Wifi preferences, under Advanced preferences, if i select "Never" for the option "Keep WiFi on during sleep", i have noticed that the Wifi turns off when the phone goes in sleep mode.
But the problem is that it does not turn back on. It stays off until i turn it back on.
Does anyone else also experience this or is my understanding off somewhere?
Thanks,
Prasad
No one else is experiencing this?
What could I be doing wrong or maybe i have set this wrong?
Any help guys?
Nope. I even noticed that since the latest update for my Z5 that wifi kinda doesn't work even tho it shows as connected after the phone has entered sleep. My XZ1 does the same. I'm assuming it's some new android power saving? My As soon as I unlock everything works fine again but if I'm downloading torrents or streaming movies to my tv i need to keep the phone plugged in so it doesn't sleep

If you select never it means: never keep wifi on during sleep = turn wifi off during sleep.
Select "always" if you want to have wifi always on.

The problem is your comprehension on the setting. Understand the setting and the options it is very clear once you understand the meaning of the setting.
You have set the phone to deny WiFi when screen off. Full stop
I experienced an issue on the first day where it would connect and then quickly disconnect while connecting to a public network. Haven't faced the issue since then again under the same circumstances.

Yes quite right.
I have set the phone tondeny wifi onky when the phone sleeps.
Does it bot mean then that when thw phone wakes up from sleep, the wifi should also turn back on?
That is how it works on other android devices.
But with xz1 once the device goes to sleep, wifi shuts down which is good.
But when i wake the device, wifi stays off. It does not turn back on.
Thanks for reading.

I see.
Not noticed anything like this.
However I have the same setting applied (WiFi off during sleep.)
So I'll test this later and report back.

It works for me dude. WiFi signal reconnects as expected when screen is turned back on after a sleep.
All I can say is Sony's OTA updates since even my z3 have always caused issues. Try a factory reset.
Thanks for testing it out and glad to know there is no issue.
Will do a reset soon enough and report back though it might take a while as i am travelling.

Try turning off data. There is a setting that keeps the lte active for faster network switches. I have same issue. Don't notice it when data is off.
I am suffering the same Wi-Fi issue. It is only since the recent update this has occurred. I've contacted Sony to no avail. It's driving me mad.
Same here (FW:47.1.A.12.145) WIFI router is with atheros chipset.
When phone is going to "sleep" wifi is switching off (even if it is set to not do so).
It seems that flushing cache partition is fixing it for some time.
