s3 wifi not working - Galaxy S III Q&A, Help & Troubleshooting

I updated to OTA jb 4.1.1 3-4 days ago
till yesterday, wifi was working normal but from today morning I see some weird problem.
When i try to connect my phone to my home's wifi, it gets connected. After that I open any internet based app, for the first time it works. then the internet stops.
I mean the wifi symbol is still there on the status bar but. it doesn't work.
I can't open any web pages, i have to turn wifi on-off to make it works, after loading one page it stops again.
But internet from the pc is working.
I tried restarting, keeping battery out for sometime, nothing happens.
What should i do?
Facing this problem first time in 5 months after updating to Jelly bean/

I have tried both the things already.

friendly bump

I have same problem as you have, like it took me sometime to finally figure it out. Try resetting your router. You see this small hole at the back of the router, hold & press it for about 20-30 seconds. Your router will now be restored to its factory settings, then connect your S3 & voila! your device is good to go.

I had the same problem at home once, I tried everything from wiping caches to reinstalling my rom. Turned out it was my router so yeah the guys above are probably correct.

Did you ever try pressing the router hole for about 20-3- seconds? If it still didn't work, try manually input the your static IP. That worked too with me,

I don't have idea about static ip
And I've seen, while my screen is on. . WiFi remains connected and if I lock screen even for a second. .WiFi goes off

Hi, Had same issue with WiFi, was doing my head in.
Problem for me was bad update from the OTA update,
go into recovery and factory reset wipe data, and cache, if still no luck then
your best solution which worked for me was download the full Samsung Official Firmware Stock from samfirmware (Google it)
and use odin to redo the phone.
Hope you get sorted. :good:

Go somewhere else with available WiFi, try connecting, if you succeed with no following issues, it's your WiFi router, if you can't connect to any other available WiFi, it's your phone, reflash ROM and test.

Have you tried turning power save mode off. In the dialer dial *#0011# then press menu button then WiFi then where it says on, turn it off. Be aware that it goes back on after every reset of your phone.

And as for it going off when your screen is off go to WiFi settings - advanced - and change the option about WiFi when screen off to always on.

I have the exact issue. I tried everything here:
* Doing static ip on my phone
* *#0011# turning wifi power save mod to off
Still the issue. I didnt reset the router as my wife's s3 does not have and also this is issue is happening to other routers as well. Please help...

same issue
i have the same issue. I just bought a new S3 four days ago. Wifi of that stopped working exactly after 1 day of the purchase. Same symptoms , it worked at my home for a day and stopped on 2nd day. After stop and restart of the wifi, it again started but then after one page being opened, it again stopped. Tried "forgetting" the wifi uid , it didn't work. Stopped the wifi power saving mode, no gain. The version is stock JB 4.1.1 (came preinstalled) . On the other router, it did work but I am sure(though haven't confirmed) that it woudl stop after a day too.
After this issue, I changed my handset from the seller(original Samsung retail shop) and now, after 2 days, it again stopped today working, on almost the same time again. The same router is used by two ipods, two laptops and one HTC One X and it's working fine. I am not sure what to say to the seller now as he simply won't agree to me but the issue is clearly there. Any help please!

I too am having this problem after updating to 4.1.2. It helps to turn off the wifi then turn it back on, and but I don't want to keep having to do this.

Sounds like an ip related issue.. Your phone remains connected to the local network but can't find it way to the Internet (dns), right? . Try setting a static ip or soft reset the router every time it happens (turn it off and then back on). Try even locating the router somewhere it doesn't get too hot. These work for me

Hi,
But this issue never came up in the ICS and with the other devices , it's working fine. Also, can you guide how to set the static IP for the GS3?
Thanks and regards
---------- Post added at 04:09 AM ---------- Previous post was at 03:31 AM ----------
Okay, did a little Google search and found how to put static IP. Gave it now but still, no joy. Ironically, yesterday , after doing a lot of search I found that I should enable "dynamic routing" on the router. I did that and internet started. Worked for the night and today morning , it stopped and now not working at all.

Any help please!

Even I have this problem on my S3 LTE version on Jelly Bean 4.1.1. Trying hard reset and changing settings on router or fixed ip on phone won't be of any help. I tried all these and the problem comes back within no time. So don't waste time. Send the unit for repair or replacement. Think of it this way, if there is a problem with your router or other routers, your other devices would also have a similar problem so suggest not to tinker with router settings. Problem is with the phone. Whether there is a problem with hardware and/or software, it's Samsung's headache to deal with. Planning to send the phone for repair shortly. Fed up with Samsung. Previously had a problem with bluetooth and screen on S2 and now Wifi. Irritating.

having quite a serious issue with the vibrant wifi

I have this issue with wifi. It's that when I'm at home, it won't connect at all to my wifi all I get is obtaining address and eventually unsuccesful, yet occasionally it does work. Then, when using other wifis, turning on wifi does make it connect and show the icon in the notification bar, but still, it won't always work. I try to get into the market but it says no network or something like that. Tried most web browsers, nothing works too. What can I do? My phone is rooted and flashed with bionix fusion rom, evn though this problem sometimes happened even with stock firmware, rooted and not rooted. What can I do? Can't really get a replacement because i bought it from overseas. HELP!!

Some routers are a tad dodgy, so it may not be the phone at all. Since we dont know what type of router or what sort of connection environment your in (how many wifi connections it's handling, etc...) it's hard to say. Still it's easier to replace a $30 router than it is a several hundred $$$ phone.
I said in the post itself that I tried more than one wifi aka router, most of them connected to a laptop and my phone at a certain time. Therefore I doubt the issue is the router. I think it's a bug. Is there no fix for this?
This is kind of a shot in the dark, but have you tried putting the phone in Airplane mode and then restarting the Wi-Fi? I've found that the cell data connection can sometimes interfere with my Wi-Fi.

I would put my money on the router, I have not seen anyone else complain about this who is running bionix. So a bug within bionix, I'm going to say no.
HOWEVER!!!!!! I had the same problem for a while. I have AT&T uverse and there 2WIRE router is total crap... I had the same exact problems as you PLUS it would not connect to my mac mini for more then a few seconds. I hooked up an older router I had laying around and BAM no more issues.
I got the same problem, but my phone is not rooted or flashed. Must be a system/software problem.

Braking connection via WiFi and freeze on lockscreen caused by WiFi

Hello,
I became a proud owner of S3. As it usually happens to me there is the problem. Namely, from time to time problem happens to me when I'm using any web browser or anything that requires an Internet connection. Say for example Opera. I'm browsing pages and suddenly ... BOOM ... 3-5 second pause in the connection over WiFi (energy saving is off and in WiFi settings - I did it via code, in the service menu). Sometimes Internet connection breaks when I'm browsing menu or writing an SMS. For example: I browse the menu and suddenly I see - WiFi stamp disappears and after a while there is info about that phone is connected again. This is the first problem.
The phone is lying, WiFi operates in the background. When I Pick up the phone and when I'm clicking home (or power) button I get the lock screen and. .. freeze. Phone is disconnected from WiFi and only time the phone reconnects to WiFi I can unlock the screen.
On what ROM were the problems? On the Stock LF2, ROOTed LF2, Omega 7.1 - 9.0 and AOKP Milestone6.
And also it does not work automatic refresh of weather (at 1 h interval) on stock widget (the Samsung weather widget).
Sorry for my bad English.
Why couldn't you have just set your wifi to never turn off in settings, wifi, advanced.....it's practically the same thing....I wouldn't be messing around with the service menu. I would wipe data/factory reset and start again bud but this time, stay away from the service menu as it's for technicians and phone repairs etc I've not once touched the service menu....
Sent from my GT-I9300 using XDA Premium HD app
I found the same problem ever since I upgraded to LH3 (the latest official release at this moment). The lock screen is frozen if: I had the WiFi Switched On, screen off either manually or timeout, then disconnected (say if I walk away from the wifi service area). When I press Power or Home button to wake the device, the lock screen is frozen.
Seems no freeze if wifi remains connected. Seems no freeze if wifi power saving mode is off (disabled via *#0011# (but setting won't stay if unit is power off).
Did both Cache wipe (didn't do factory reset) but makes no difference. Tried "never turn off" also makes no difference (probably because it will turn off anyway when connection is dropped)
The upgrade seems worser than before...
Any hints please...
This seems to be common but not always the same fix, my wifi constantly drops out and reconnects immediately (ruining any downloads/streaming) , i have tried the service mode, factory reset, different kernels, sleep time, static IP's, JB vs ICS Roms / Stock roms, you name it i have tried it and it STILL is doing it. Weird thing is..dont think it dropped out and reconnected when i was stock and unrooted, but as i said, tried stock rom and to no avail
Any ideas?

Go full unrooted stock and send the phone in for warranty repair. It's the smartest thing to do if a problem persists after lots of ROM switching and factory resetting.

That's would be the smartest thing to do, indeed. But... Warranty expired centuries ago.
Any clue what is causing this not uncommon problem?

Try visiting a(not crowded) place with public Wi-Fi, and see if the issue persists.
If it starts to work fine, get a new router, preferably with 802.11n support. If you buy a N compatible router, check all of your Wi-Fi capable devices for N support, and if one of them doesn't, make them N compatible(if it's a computer, get a new N compatible Wi-Fi card or USB reciever, if it's something else, well, you can't do anything else other than buying a newer version of it with N support, or not using that device's Wi-Fi feature at all) because your router will operate at an older mode even if one of your devices doesn't support N.

samsung galaxy s3 wifi not auto connect to home network

Please can anyone help.
Up till a couple of days ago my s3 would automatically connect to my wifi signal at home as soon as I walked into my house, haven't changed any thing but it no won't connect until either I reboot or switch wifi off and then back on again . Tried rebooting phone which works for the first connection but subsequently won't connect again after sleep or at least the phone not being used for a while. Also switching wifi off and back on again works but as before once wi fi shuts down it won't reconnect by just swiping the screen and taking the phone off of standby.
Hope that was clear enough lol
Many thanks Ian

Reboot the modem/router and try again. If that doesn`t help press your wifi connection in settings and reinsert the password and reboot.

Yes I've found plenty of things relating to wifi issues on the phone but none specifically to this one so if anyone could help I would be grateful.
I assume you've tried forgetting the network and re-entering the details.
Also try playing with the Wi-Fi sleep policy, in the past this has caused some problems with the stability of the connection. Settings, Wi-Fi, menu, advanced.
Also it might be on the router side. Try changing the channel on the router, and if it's dual band set it to 2.4ghz instead of 5.

Back up data. Factory reset.
Update firmware.
Change kernel.
That's three possible fixes.

I cannot seem to get the WIFI Sleep to work at all. Even when set to NEVER on when asleep I can see in the battery stats that WIFI has stayed on the entire time. Any idea why this is?
can you tell us the ROM and kernel you are using (if you are using custom)? I have never had any issues with stock kernel myself.
also, did you hide your wifi SSID? in the past, it might cause some issues...

			
				
I was having the same problem, try this.. Setting - wifi - advanced - keep wifi on during sleep - Always.
I haven't noticed more battery use,

if you want another option besides backing up your data, doing a full wipe, and reloading your data, try a different kernel...easy fix that seems to fix these problems most of the time...the kernel is responsible for your wifi, gps, bluetooth, cpu, gpu, etc...so swapping it out should fix an issue like that

Xperia U: very weird wifi problem

My girlfriends XU is acting up ultimately weird..
Since some time we have this problem:
Wi-Fi only works for about 3 minutes when connecting to a wifi signal, yet the wifi signal icon indicates as if it has a good connection. The only way to regain connection again is to reboot, but then the same problem repeats itself, after a few minutes wi-fi is not working anymore. Also in the wifi-indicator the "send" arrow works, the "receive" arrow doesn't.
Basically if you want to discover a new wi-fi connection you need to reboot the phone also, because otherwise the previous connected wi-fi signal remains (it freezes as stated before after about 3 minutes).
Tried a factory reset already.. Didn't work. The phone runs the stock sony android 4.0.4.
Any idea's ?

[Q] WiFi failing after clean install

Hi
I'm a first time poster here
I'm having a problem with the wifi on my s3. I've searched the forums but the problems see to be different.
I can install a rom and when it goes through the initial account setup. when i get to the wifi i see my home network strong signal. i tap it and put in the password and it disappears, leaving me with my network not in range. Which is strange because it's working fine on this laptop.
i did the power saving turn off via *#0011# - no luck
i've wiped and reinstalled numerous times. each time i can tap on my network before it vanishes
Please point me in the right direction

Just tried android revolution rom. same problem
it picks up some networks, very low signal, but not the home router it is on top of. i can turn the wifi on and off and occasionally get a glimpse of my home network, but then it disappears.
really frustrating as i can't log into my google account and download contact info. makes the phone almost useless
Wipe phone flash your original stock rom or its update and test .
