[Q] wifi problem after update to jellybean 4.1.2

hey guys.
i got the new update of jellybean and i have a wifi issue now. It's stuck on obtaining ip address and after one minute of searching it says that the signal is to low to connect even tho i'm in the same room.
I've tried fixing the issue by resetting my wifi with no luck, even factory resting my phone with no luck either. I haven't put a new rom or changed any features on the phone.
please help.
phone info
make: samsung galaxy s3 4g
network: telstra
model: gt-i9305t
android version: 4.1.2

Im having same issue currently trying to get my handset replaced by three!! Im guessing its a common problem

I`ve had this problem with my phone from day one. Samsung have allegedly repaired it three times and Orange once. On the third attempt by Samsung they said they can`t replicate the problem.
I`ve had this problem on 4.1.1. Upgrading to 4.1.2 didn`t help

Try changing the WiFi region code in the advanced WiFi section

Like I said. Go into your WiFi. Go to the advanced WiFi menu and change the WiFi region code. Its all there if you look

Have you tried to forget the network and re connect to it
Sent from Ripper Rom I9305

Tried it all just connects and say obtaining ip address or failed weak signal even though its showing full strength!! The only work around is to turn wifi powersave off,

Try to forget it, then try again.

Try these tips
Wifi settings
open your box/modem 192.168.1.1 or 192.168.0.1 on your PC web browser
unable "automatic frequency or channel" on your wifi setting or try to change channel
check also if your Mac adress filter is enable. disable it
Wifi congestion by channel
Wipe Cache
Forget you network
cut the wifi
reboot your phone in Recovery Mode
wipe cache partition
Reboot
lauch wifi and connect to your network

Use the search!

I have a different issue with the wifi, it connects and reconnects several times in its own, did not have this problem before.

Try to flash a custom kernel like perseus <3

wifi problems after update to 4.1.2
Hi,
I found that saved profiles are randomly disabled and can be enabled using the following app "Wifi Profile manager". The app "Wifi Fixer" allows for monitering, reconnecting and logging the state of your Wifi connection. After seeing this I send an email to Samsung Netherlands. (that was today). Another work arround is to forget the network, reboot the device and try again. When searching the internet I also found this not to be device related. Many more devices have this problem after the recent update.
regards,
Robert

WiFi disconnection?

I'm suffering from WiFi disconnects
The ZR disconnects and reconnects every few minutes
The vendor stated that if the router (AP) does not support the 802.11n standard, the WiFi will disconnect
But, SHOULD it disconnect?
I have tested on several APs, if I use these devices as a WiFi host, the WiFi disconnects:
- Dlink DI-624S
- RUCKUS WIRELESS ( unknown model )
And these APs work with ZR smoothly without disconnects:
- HTC Incredible S
- Buffalo WHR-HP-G450
- Dlink DIR-632
Does anyone has the same problem?
Any information will be helpful
P.S. I'm running stock 4.2.2 on stock kernel

Similar
got the same problem as yours, but mine's only disconnecting when I'm using AirDroid and sending large files to my phone which do not happen when I'm just browsing the web. no Idea about it though

I am using many wifi connections, in my house which does not support 802.11n, in my work which we have several ap, in university, friends houses, I have used it twice in train stations and public places!
And no disconnections! and by that I mean absolutely no problem like yours! and I have C5502 like you (the non-LTE one!) so I'm not sure about that, but you might want to try define your router manually!

Same as the other guy, wifi works flawleslly on my c5502

Wifi is driving me crazy please help

Hello everyone I tried searching before posting this but I couldn't really find any good info
Ive stock 4,3 not rooted and I've no idea about my bootloader but most probably locked
I'm having a sudden Wifi disconnect like each 20 minutes and when I don't have a disconnect the net is terribly slow!
I'm wondering anyone else having same troubles or it's just my bad luck...

I had problem with my wifi on android 4.2.2. Problems were likely like yours. Yesterday i have flashed my phone to stock notbranded android 4.3 and it works like charm. Maybe you should think about also updating your phone with this ROM ?

Stupid question but is could it be a router problem, since you also had problems with other versions? Or do you have this problem with other wifi networks too?

Hello,
Since the official update to Android 4.3 I also get issues with wlan when I am at work.
It might connect normally at first
But after some time I notice that I do not longer get data over it and most of the time it does no longer find the wlan in the settings, everyone else however can still connect fine, however most people are using iPhones but Even a galaxy s3 had no issues so it is no issue with the access point.
I also had it 2 times that I couldn't even disable wlan anymore (active again after reopening the settings)
Funny thing is that I have no issues with my home wlan that is a fritzbox.
On android 4.2.2 I never had an issue.
Everything stock, no root.
I am using a smartwatch 2. Not sure why it got mentioned here.

Check the router for a seeing that users 2 channels at once to increase bandwidth (not a dual broadcast setting for n and g or 2.4 and 5GHz). I have seen this problem on several android phones when enabled.

Same problem after updating to a 4.3 Rom based on z1... Definitely not my Internet/router going out... Running a dd-with on latest firmware... No problems until phone was updated. Only thing that brings wifi back is resetting phone....

Every update seems to have it's own bugs, this is very annoying from Sony. I can get my Wi-Fi back by switching the WiFi off then back on from phone settings.
Mainly This and the Bluetooth bug is making me think about getting the s5 for my next upgrade.

With the nexus 6 coming up I may have to bite the bullet on that... If it shares any kind of life proofing the way Sony has gone of course. The waterproofing drew me to this to be honest... Lost to many devices because of accidents. (yay for having kids)

Wi-Fi disconnects all the time! Is this a normal problem?

When i use my Wi-Fi regulary, 5 minute once it disconnects from my own internet.
Is this problem of Sony firmware, or should i check up my device?

How far are you from your router? How about other devices at the same range?

I am far about 4 meters my router. And this problem still happens even I next to router.
And there is no one in my house having this problem.

Have a check up for the device. Though i have read in the forums of other members with the z1 also having wifi troubles
