[Q] WIFI issue after updating to Jellybean - Galaxy S III Q&A, Help & Troubleshooting

is anyone having a problem with the wifi after updating to jellybean for s3?
inital connection to WIFI works but after a certain period of time, the wifi stopped working and i need to restart the wifi again for internet to load. IT happens all the time now after leaving my phone with WIFI on.
Constant restarting WIFI to get connection does not happen in ICS..

No such problem for me with JB LJ5 stock or custom!!!
Might be your modem-router....

This happens to me too. It's fine for me at work, but when I'm at home the wifi fails to connect after some time. Are you using dd-wrt at home? I am and I'm wondering if that's the issue.

I find that having my wifi set to always on in advanced I get better wifi and slow drain, having it on wifi off while asleep makes your wifi keep disconnecting and reconnecting. Best way is to switch wifi off when you don't need it.
Also some battery saving apps I've found to stop wifi and need to keep reconnecting, this has to be changed in the settings

wi fi dropped

Hi, Mine is Galaxy Note 2 i317 with Jelly Bean 4.1.1. I did have similar issue. I took two smart phones to Target, one is ICS 4.0.3 and the Note 2 is 4.1.1.
The 4.0.3 never has any issues with wi fi connection. But the Note 2 keeps on dropping the connection. I ran an application wifi analyzer to check the available networks. It turns out that Target has so many routers that are using the same ssid, i.e. "Target Guest Wi-Fi". There are channel 1, 6, 11, etc, as well as many 5Gs. I did an alias for every available connection. Then I pick one of the stronger signal strength 5G and connected to it.
After that no connection was dropped.
The point is that you should try to connect to the strongest signal SSID so that the Note 2 won't keep on dropping the weak connection.
I have no idea why the ICS 4.0.3 can handle better than the 4.1.1 Jelly Bean as far as wifi is concerned.

Same problem!

I'm experiencing the same problem since updating to Jelly Bean 4.1.1 on my HTC ONE X. So it seems to be an Android issue, not specific to Samsung or HTC.
I connect to my home network over WIFI, everything works fine until after a little while my apps seem unable to connect to any data/internet. They just time out or come up with error messages about connection problems.
Sure enough, if I disconnect and reconnect to WIFI, everything starts working again... for a little while.
It's like the WIFI goes to sleep, but forgets to wake-up again.
And there is no indication on the phone, ie. it still shows as connected.

I echo that? It's 3 months later... has anyone figure anything out in regards to this issue?

Mine shipped with JB already. Sometimes, when reboot, it doesn't connect to my WIFI network, unless i disable WIGI connection and re-enable it...

[Q] Wifi problem - dropping

I am currently on Gingerreal 2.0. I can connect to my wifi, but suddenly, somehow after a few minutes the connection drops and then switches back on...It is not a router issue as my laptop and other phone works fine without dropping.

I get the problem sometime.. make sure that your router is not blocked and that your room door is not closed or other obstacles.. this will affect the signal.. just press scan again on the wifi menu and it should work.

No, no , you did not get my point. It drops the connection and then automatically reconnects even if I keep it next to the router.
NOTE: My wifi screen off is set to :Never.

Problem with cm9 and wifi

Hi i went from stock ics on my ray to cm9 by followingnexact step by step guide provided by cm9. Used their kernel as well. Have never modded my phone before. Having a small problem with wifi though. After my phone has been asleep for a while, if i wake it up the wifi icon in status bar is no longer blue its a dark grey and i can no longer browse anything or use the internet. Ive tried rebooting. I did the whole wipe cache etc when installing cm9. In wifi settings in advanced ive also left the setting to "leave wifi on when sleep" checked. If i turn off and on the wifi connection the phone ofcourse is able to reconnect again the icon is blue and i can connect. It not jsut a one off thing its been happening since i isntalled the rom.
If i wakek from sleep a few minutes later i have no issue with wifi. Its only when its been sleep for a while do i have this issue.
Any solutions?
I have the exact same problem but for me it's even bigger, whenever i turn on wifi on my modem, i can connect to internet on my phone, but after awhile i lose my connection completely, on my phone and on my pc also, the only way to get it back is to reset my router and wait for like 5-10minutes...

If its also an issue with your. Pc then your issue might be also the router.
My other devices actually work fine in my case its oky this phone that has issues. Macbook iphone ipad nexus s no problems with those.
Same issue here. I can see available networks but unable to connect. There should be no problem with the wifi router as all my other devices work well and I have tried another router. Now I have to flash back to stock firmware.

Your issue seems more severe than mine. Mine actually connects and works, just that when it wakes from long sleep it wont work until i turn off and on wifi.
I get this problem too, but my problem even worse than yours. My wifi lose it's connection after a while, but the icon on status bar shows it's connected, running ping test, browse, even play store can't be accessed. I pinged the router and got unreachable.
And yeah, this problem occurs when I'm using all ICS based rom..
Anybody has any idea if this is a known problem, or if its just us few having thisissue?

[Q] Strange WIFI connectivity issue...

Hey guys,
OK Ive got a strange problem with one of my Galaxy S3's!
It will not connect to some WIFI connections! It will say 'Obtaining IP address' then 'Failed to obtain IP address' and then loops itself doing the same thing over and over...?
I have two S3's and my other rooted device is fine. The one that has the problem is running a standard O2 4.3 rom (Un-rooted)
My rooted phone is also running 4.3.
Anyone experienced a similar problem? I have had this problem with 4 or 5 WIFI connections now, including my home one which is rather annoying! I have tried the obvious and rebooted my router, which hasn't helped!
Any advice welcomed!

I've had issues with the quality of my internet connection being checked, and then the connection being killed due to "slow internet connection", even on strong Wifi networks. Solution turned out to be to uncheck the automatic network switch in the advanced Wifi settings.

How so, when I have an identical phone sat right next to it with the same version of Android and that phone connects perfectly?
The only difference is one phone is rooted, the other is not (Both running 4.3, just different kernal number and build number)
Well wifi is a function of the kernel .

Possible Wi-Fi issues?

So far I'm loving this tablet (even without root) but have noticed that I lose internet access if I'm browsing for a long time. I still have full Wi-Fi signal (I'm only a couple of feet from my router) but no internet access until I disable and re-enable Wi-Fi. This has happened several times since getting the tablet last Friday. I have 3 other Android devices including an Xperia Z1 and none of those have a problem. It has happened on two different Wi-Fi networks so it is definitely not a router issue. I have tried disabling and enabling the options under Advanced Wi-Fi such as 'Scanning always available' and 'Wi-Fi optimisation' but none help.
There is a Wi-Fi Check app preloaded on the Z3TC and it shows it is failing on test 4 - Gateway/DNS. All of my other devices remain connected.
Anyone else noticed a similar problem? I know it is early days but would like to know if I should return it before I get too attached to it!

I noticed at the beginning also the same...I had some connection problems in the browser and had to reload the page.
Do you have LTE or Wifi Version? Mine is LTE.

Just the 16GB Wi-Fi only version. I did some tests on my work Wi-Fi (streaming music and browsing) and the connection was stable. I'll try static IP and a few other things and test again at home.
Cheers
Yep, I have the same problem.
Wifi connection is not stable. Sometimes I have to wait for few seconds for it to reconnect.
Mine is 16 gb Wifi version only.
Is this a software issue.? Wondering if I should return it.
Anyone found a solution?

Actually, I haven't the problem again since the first week. I'm thinking it may have been a router issue after all (I'm using a Virgin Media SuperHub 2). I've not had any disconnections issues since.
Have you tried the Wi-Fi Test app?
