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 .

Guys i need some serious help , I am using u8150 ideos, My Wi-fi or Wifi portable hotspot has just stopped working no matter how much i wipe data factory reset install stock rom or change any rom it doesnt work. First it used to give Error in between connection now it doesnt even get On. it says Error below Wi-Fi doesnt detect any network there is 1 mine and 2-3 in the area that it used to detect, i installed CM7 rom on my mob once and it had many bugs and a kernel too am sure its a kernel or some problem .. i doubt there is any hardware problem cuz everything else works just fine!
in anger i also deleted a wifi folder from root explorer thinking it will remake itself but delete or not the wifi doesnt work. Help would be appreciated.
I am having this same problem. can anyone help please ?
Download Odin One Click Downloader, connect your phone to your comp while in download mode, press start on Odin and wait. this will take you back to the OS you bought it from. for example, if you got Ur phone in android eclair or ics or GB or whatever, itll go back to that way. use samsung kies mini to upgrade your phone back
My WiFi originally had no issues when I was on the stock 2.3.6 ROM/Siyah. Then I got curious about ICS and installed Lite'ning ROM 2.2 Went through numerous issues with my apps, including the aforementioned WiFi issues before I decided to just quit for now and revert to my nandroid backup of GB.
Problem is, I still seem to have WiFi issues back on GB. Didn't use to be a problem before though. I wasn't able to make a backup of the DXKL1 modem, but I did reflash XXKL1 in an attempt to fix the issue upon reverting to GB. Didn't seem to help much though. I was going to try reverting to DXKL1, however the Multiupload download link is now broken, and no one seems to have a copy of it floating around.
WiFi won't automatically connect sometimes. And on my home network (WPA2-AES or TKIP, same issue), it has trouble connecting on occasion, looping from "Authenticating" to "Saved, secured with PSK" but oftentimes never actually establishing a connection successfully.
Any ideas would be appreciated. So would a backup of DXKL1, if that is in any way related. Thanks!
Try changing kernel .

I am having the same issue with ICS. And I'm sorry to say, the only fix I found until now is to go back to GB. KL1 also has some issues, and so I went even further back to KI4.
Good luck!

I had the same problem when trying to connect to my home wifi network. The phone was constantly connecting, authenticating, connecting, authenticating ...
Then I tried to connect without forcing an ip address and when it was connected I change the ip and put the one that interested me. I think it's an error in the original rom
Thing is, I'm back on GB and it seems to have "kept" the problem from my venture into ICS.
I'm currently on Siyah 2.6.14, which I've had no issues with in the past. The only thing I can see that remains different from pre-ICS nandroid is my modem, which is now XXKL1 when it used to be DXKL1.
Hope anyone can help solve this problem. I also wish my WiFi would automatically connect again.
Maby try a data / factory wipe
Yes full wipe and restore your original firmware .
Its not unusual for those that flashed ICS and then jumped back to GB to have varying problems .
....................................
Clean Slate for those that balls up the firmware .Or need to return to service or decide if its hardware/firmware problem .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .
jje
full wipes and install rom from internal SD not external SD
Crap, hoped it wouldn't have to come to that. Didn't really want to since I'm now on CM9 with all my settings set up nicely. WiFi still having the same issues.
I take it nobody else has experienced these issues and solved them?
Rooted My GT-P7510 (WiFi) a few days ago following these instructions.
http://forum.xda-developers.com/showthread.php?t=1474971
Flashed with Team Kang ICS Rom. Everything seemed to be working in order until today when I tried to hook the USB to the PC to move some videos over to my Tab. Problem is, it will not recognize the Tab at all. I tried re-downloading Kies Air with no luck. I then decided to go back to stock configuration and unroot the Tablet. Well since I can't pull the original file from my PC to do this I'm kinda screwed. To make matters worse I decided to do a clean install by doing a factory data reset 3X, Wipe cache 3X, and Wipe Dalvek Calche 3X, then reboot. Well, that all went fine until trying to setup the Tab again. I try to sign into my g mail account but, upon initial setup I get this message:
Can't establish a reliable connection to the server.
This could be a temporary problem or your Android device may not be provisioned for data services. If it continues call customer support.
I'm connecting to my home WiFi so I don't need to worry about it being a data issue. Everything else in the house is working fine.
So now I'm trying to figure out how to unroot the tab and without the internet or way a to get the PC to recognize it. I pretty much have a $400 paper wait. Any help or suggestions would be great. Thanks!
I think the best you can do is use odin to flash stock firmware. Go to www.sammobile.com, download the right firmware four your device and flash away!!

Have you enabled MTP data transfer?
Go to settings- storage- options [Top right corner] - USB computer connection- and see if MTP is checked or unchecked. It should be checked in order for the device to be recognized.
Hope this helps.
Hii,
Yesterday i was uploading a video to whatsapp my wifi stopped. when i try to reconnect it it connects but no internet access. i ve two laptops
one i am using to create a hotspot using a usb dongle and provide wifi for my phone and my second laptop at the same time. It was working fine
for over 6 months and suddenly the problem showed up. i am running the latest 4.3 on my device; wifi on 4.3 was working as charm since the
update 10 days ago. Following are the fixes I tried and failed
1. restart the phone couple of times
2. restored the phone to 4.2.2 (i had backup)
3. used wifi fixer and wifi manager app
4. factory reset the phone
5. disabled power saving in service mode (*#0011#)
6. used static ip instead of DHCP (although i dont know what i was doing.. i looked up a thread and followed their steps)
7. try pinging ( no response from the server)
GUYS PLEASE HELP!!!! :crying::crying:
You are posting in the wrong forum .
Suggest you wipe phone and flash stock rom but read the faqs and guides first .
Good day,
I have a samsung galaxy s3 i9305 LTE and I have been using this device without problems for around 2 years now. It runs on Jellybean 4.3 baseband version i9305zhucnb1. It has been running on this firmware for a couple months now ever since it has been rolled out. The problem is, the WIFI suddenly stopped working. Never had this problem before and I actually never had any problems with this device ever. Whenever I turn on WIFI, it detects my home networks and other networks wherever I go but whenever I try to connect, it just shows saved secured, and sometimes authentication error after a couple of attempts. I have other WIFI devices at home and all are working perfectly. I tried forgetting the networks and I am positive that the WIFI password is correct. I tried to restore the device to facroty settings hoping that it would work. I tried accessing my router and I'm sure my device isn;t blocked. I even configured my routers to only accept the mac address of my device and block all others but still wouldn't connect. I tried rooting my device via odin but my device blocks root access and shows the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". I tried rooting it to try flashing custom roms. I also tried dialling *#0011# to configure my wifi but it still does not work. I don't think that the problem is my firmware because I had it for months and it didn't update before the issue occured. I was also about to try downgrading it to an ICS stock rom since I can't root it to try custom ROMs. I've been trying to fix this for days now. Can you guys give me a step by step instruction on how to fix this if it is at all possible? And maybe give me a link where I can download ICS or lower stock ROM's for this device. I think I have to use a TGY firmware, though I don't have an idea what it means. Thanks!
Wifi module
Maybe you've dropped your phone and the WIFI module loosened, and it can't work correctl?

Maybe it's time for factory reset? I know that's the easy solution and most complicated but you should do it from time to time.

help
i decided to have it checked by a local technician and according to them, this was still a software issue. i dont know what to do anymore. they insisted that i should just keep flashing stock roms to fix these. already tried flashing the 4.3 tgy jellybean stock rom so i was thinking of flashing other version stocks. can anyone give e a good link where i can download tgy stock roms 4.1.2 or even ICS stock roms. I also am having problems with rooting the device. it gives me error message "an application attempted to access system on your device without authorization. this attempt has been blocked." after flashing autoroot in odin. my knox is not installed. thanks.

dont know
the first time i brought this to them is when i attempted to flash an incompatible firmware. they also did not fix it. they said they dont have any available stock rom for i9305 and told me to download and flash one. mayba im just gonna have to look for a different technician when i have free time. so for the mean time, im trying to look for other fixes. btw, i tried downloading a tgy 4.1.2 stock rom and it does not flash successfully. for now i'm thinking of rooting and flashing custom roms. but whenever i flash auto root. it gives me the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". i tried updating supersu still the same thing. i manually installed root checker and says it does not have root access and it shows the said error message again. what should i do with that? Thanks
