I have flashed official rom I9300ZSEMA1 (Hong Kong) 4.1.2 by Odin and after having flashed, I wiped cache and user data in the recovery.
In spite of all that I have done, it just can't connect to my network via WiFi. It showed "Obtaining IP adress" for a very long time and finally failed to connect. I tried using static IP and succeeded connecting to my network, but, unfortunately, it was still unable to connect to the Internet.
My phone works fine with the offical 4.1.1 rom, and I have proved that my router and network work fine, too. So I think there must be something wrong with I9300ZSEMA1.
Is there any solution?
Thank you!!!

I can't connect to wifi ,it says authentication error occurred ,when I change back to stock rom, it show me saved and secured
sorry to bump such an old thread, but i can't seem to find a fix on this authentication error.. it just appeared all of a sudden, i have not done anything special with the router nor on my S3, my other devices can connect with wifi smoothly.
well, to start with, i was able to connect before.
any suggestions on how to fix this? i just might send this to the service center -.-
things i have tried:
-restart the router
-entered router details manually on my s3
-flashed another custom rom
-flashed another modem, kernel
-flashed a stock firmware
-reset the router
i have searched high and low in google and still no solution
I have looked around for a couple of hours and cannot find any answer to this.
I have just got my S3 back from being repaired after Sudden Death, and have rooted using Odin and CWM Touch 6.0.2.8, and flashed the latest cm10.1 Nightly (Currently 17022013)
I am able to connect to the mobile network (3 UK) and get a good H+ connection.
I cleared all of my saved wifi networks, and try to connect to my home connection. It Accepts the WPA key, and gets to 'Obtaining IP Address...' and does not go any further.
I have tried now on several wireless networks including insecure ones, and it will not connect.
Please help if you've had anything similar, or if I need to provide more information, a log of some kind
I have installed the latest nightly from CM10.1 and the issue is still present. Which makes me think that it is not a CM issue.
I will be re-flashing the stock image of the phone to confirm this shortly. Will post results

Hi All,
I ahve a problem with my SGS3 GT I 9300 Android 4.1.2. I cant connect to any Wifi. When I try to connect I get the message "Authentication error". The router has WPA2 encryption. Even when I setup the router with no encryption it gives this error.
What I did before:
I have had another SGS3 with the same Software on it and wanted to make a nandroid backup to the new SGS3. This worked fine and everything was good except the wifi.
I already tried to connect with adb shell to kill wpa_supplicant but also with no success.
I am out of ideas what I can do. I dont want to wipe the whole phone again and setup everything.
Please help!!!

No then you could try just flashing a kernel via Odin .

Hello community,
Trying to get help about Samsung Galaxy S3 unrooted with custum rom (Dirty Unicorns 4.4.4 KitKat) , after installing a custom kitkat rom my wifi seems to be not working.
Finding my own home wifi station pressing to connect it shows: Connecting... and then Saved. I cant connect. Singal from full went only to 1 ! Even when i'm standing near my router.
Sometimes it shows "Obtaining IP Adress..." but still gets back to "Saved" .
Any solutions? Waiting.
EDIT: Done factory and cache wipes! Nothing changed.
if you got a custom rom ,then your phone is rooted . My advice is when you flash a rom read something about it what is good and what is not .
Try to flash a stock rom or other rom to check your wi fi connection ( make sure isn't your wifi router also) if problem persist then is related to hardware.
Actually i read what is good and bad. But in this custom rom doesnt anyone said about wifi connections anything..
I connect to my router but there is no internet.
Here is the deal
I installed MIUI v5 OmniROM 4.4 (Android 4.4.2) ver 4.6.20
Everything OK, I linked my G acc, updated my apps via WIFI. After that I was outside using my mobile data connection. When I come back home I tried to connect to my wifi network and here starts the problem - connects but no internet. The mobile data is still working.
Reinstalled the ROM, wipe cache, dalvik, format everthing and still nothing.
Changed back to my old ROM efeXTREME Lite-ROM I9300UBUGNG1 (Jelly Bean 4.3) but the problem is still here. I haven't tried to connect to other network, because everyone are locked, tomorrow will try some open ones, but I don't think the router is the problem.
Reset the router first, next try full wipe of the phone then flash full stock firmware.
