[FIX][GUIDE] S3 can't connect to WIFI

I've noticed lately that there are some unlucky victims of this weird tragedy, the infamous Authenication Error. I have experienced this and it is downright annoying :silly:
I have searched high and low on how to get this sorted out and found some methods and tricks to do the job.
you may have tried:
-restart the router
-entered router details manually on s3
-flashed another custom rom
-flashed another modem, kernel
-flashed a stock firmware
-reset the router
-restore factory settings
-wipe cache/fix permissions
i suggest you try the methods out to see which does the job for you. i followed some steps from this Q&A thread
ONE FIX FOR ONE DUDE MIGHT NOT BE A FIX FOR ANOTHER DUDE

METHOD A: WIFI POWERSAVING MODE OFF
1. Go to dialer
2. dial *#0011#
3. press menu button
4. select wifi
5. turn off wifi powersaving mode
METHOD B: FACTORY RESET
METHOD C: FLASH STOCK ROM/FIRMWARE
go to sammobile.com, look for a susceptible ROM there and flash via odin.. don't forget to wipe everything :fingers-crossed:
METHOD D: KILL wpa_supplicant thanks d4fseeker!
1. Connect your phone to the computer and open adb shell
2. Kill any process named wpa_supplicant and type:
Code:
wpa_supplicant -dd -i wlan0 -f /sdcard/wifi.log -c /etc/wifi/wpa_supplicant.conf
3.Then attach the generated logfile after having tried connecting to a wifi network.
**Alternatively you can run "wpa_cli" and show it's output.
METHOD E: SETUP STATIC IP
1. Go to Settings
2. Go to Wi-Fi
3. Choose Wi-Fi router
4. press Show advance options
5. change DHCP to static
6. input your ip the same thats appearing on your router
**TEMPORARY FIX only, you have to input the static ip everytime you connect
METHOD F: ADD A RESERVE IP ADDRESS
go to router and add a reserve IP address same one on your phone
METHOD G: EXTREME WIPE thanks slking1989!
1. back up via android. Copy backup to pc if u try this and it doesn't work u cant go back to before. Also backup and apps or pics music etc to pc
2. Download latest stock Rom with root
3. full Wipe, wipe cache partition, wipe dalvik cache. Flash latest wanam stock Rom. And repeat the wiping in recovery again. Full, cache and dalvik. Fix permissions.
4. Now reboot. And test if u still have the problem. As I did still. If not... yay you!
5. Do a hard reset. Yes a factory reset. NOT a full wipe via recovery. A reset via settings/backup and wipe/factory personal data reset. WARNING by doing this you will lose all app settings. All android backups and all data on internal storage. I believe this will also leave your ext sd contents unusable so ALWAYS backup to pc!
6. Repeat steps 3 and 4 again. This made my WiFi range and connectivity problems
Disappear! Although I still had authentication errors
7.Then repeat step 5 and see your outcome. It's seems for me atleast, that a double wipe was necessary.

I've tried everything as per above and on the other thread and I'm still having the same issue. The other problem is it does at times randomly connect, at random speeds. Sometimes I'll get 1mbps. Really annoying. A few times I've had a steady connection, this has nothing to do with the password. I'm having the same issue even connecting to open networks with no authentication.
Could it be a hardware issue? I think the issue started with me when the phone severely overheated overnight.

It is not a hardware issue. It is merely a software problem, no need to panic. I am still experiencing the problem when i connect to my old wifi router. I believe i have read it online that ever since the JB updates, the S3 wont connect to any insecure wifi routers for safety purposes..

I've given up hope. After trying AOSP and Standard roms, full wipes multiple times and flashing via odin nothing has helped. Mobile hot spot does not work either, this leads me to believe it's a hardware issue.
It wouldn't make sense that they'd deny access to open routers since public hotspot networks are open but require authentication via http.

Board replaced for wifi error
I too had the wifi problem that it would simply not connect to my network . My phone was in warranty . I had tried the above steps . Except *#0011# none worked for me , and that too after reboot I had to press *#0011# again . Not to mention the wifi power saving off would eat my battery like mad . I went to the samsung service centre (Mumbai/India) . They checked my phone , said the board needed to be replaced and kept it for two days . Voila ! two days later board replaced and that to the non SDS one . I checked it on playstore . Sadly they did not give me the 32gb Board . But its ok . Im happy .

can anyone please help me i am on firmware 4.1.2 but when i turn the wifi on it says turning on and it is stuck there forever??

Try Triangle away
Another method that works to me was trying the trinagle away app, try it if you intent everything else before

The problem disappeared when my router was modified to B mode only.
Try confirming it by changing your router to G-Only mode (no connection)
and then B-Only mode (connects each time)

Is this topic still active? You see I have the same problem too. I've done the method/s mentioned above and nothing happens. Wifi still not working if it's away from the router for like 1 meter. But it does work when I put my phone on the top of the router

Help

Wifi Turning on Stuck

UPDATE - Problem sorted via philos64 thread at the top...
Should've tried that 1st, but posted here hoping someone would confirm that was the route to take, as it wasn't actually bricked... Never mind, all done..
Why??? Was out earlier so I turned my wi-fi off and my mobile on and everything was working fine..
When I got home, I turned the mobile off and tried to turn wifi back on, but it is hanging on 'Turning wifi On.'
Tried rebooted the tablet a few times and rebooting the router, (BT HomeHub 3), but still the same problem.
This N7 is rooted and running 4.2.2.
When I look at the Advanced Wifi the MAC and IP address are unavailable.
When I go into Wifi Analyzer it says the wifi needs to be turned on and tries but gets same hang and retries...
On the left of the analyzer it shows my Wifi ID with a mac address underneath with a yellow triangle and 'No Signal!' in red.
The wifi from the router is working as my phone is connected via wifi.
Any ideas please people ???
:crying:

going for the post with the most views and zero replies is not on my bucket list... So I'm going to reply to myself..
An Update....
The problem is still there, so I went into bootloader - recovery mode....Then I went into Android system Recovery.
I selected cache then wipe dta/factory reset.. Reboot then starts tablet as new with the unlocked symbol, then goes through the initial setup. Select language, then it does Select wifi and displays 'Turning on wifi'.. Hung...
Would flashing it via Nexus root toolkit sort out then problem... If so, any clues what flash and how...
If it wouldn't fix it... Is the tablet now bricked??
Please answer someone if you know..
Cheers

There have been several posts about wi-fi problems if the outer shell of the N7 is separated and not fully locked in. A loose or separated shell can cause a disconnect in the wi-fi antenna. Check for any separation and maybe squeeze the front and back together all the way around the outer edge.

I did read them and a lot of other threads but they were mainly to do with wi-fi looping and not connecting.... I couldn't find any other post regarding just 'turning it on'.... And seeing as it's sorted with just a flash of the stock rom, I can safely assume this problem had nothing to do with hardware...
Hence why I was surprised I was the only 1 with this 'type' of prob.... (but I didn't read every post so I may have missed one).

Same problem too

im experiencing the same thing. im using Samsung galaxy S4 i9505 LTE and on android 4.3/ rooted Baseband i9505XXUEMJ5. it happened when i was trying to erase all the bloatware on my phone using Trulyclean by schoolsux. after i flashed the script i started having this problem.so far ive tried to do a factory reset by using custom recovery, tried to download the modem fix and flashed it through odin and do the advanced settings on wifi and uncheck the auto network switch. The problem that i have is yes it say "connecting" for 2-3 minutes then it gives you a list of possible wifi connections and then you connect. another 2-3 minutes then it wont connect. repeat the steps and now i can connect, then if you turn off the wifi you will have to go through the whole process again. it doesnt save any wifi connections you have connected before. there are 2 other ways i havnt tried yet and that is to flash a different kernel. a custom kernel and reflashing my phone again with the android 4.3 then root:laugh: for the nth time already:fingers-crossed:

i have same issue with htc one x, my wifi doesn't wan't to turn on. it stuck on "turning on...", i tried to flash different roms, etc, now i think about flashing kernel, did you do that? did it help?

Same problem on N4
Have had the exact same problem not once but twice. One day it works perfectly fine. Next day, it just stops at turning on process.
On my N4 the 4.2 was working fine. Along comes the 4.3 OTA update and the wifi stops working. Does not startup or show the mac addr either.
Did factory reset, wipe cache and even reflash binary from google stock images. No relief.
One day, the wife using gmaps started the gps location service and pop the wifi started,
Now after the 4.4 OTA all seemed to work well till yesterday and pop the wifi breaks down. the earlier trick of gmaps does not seem to work. I think one of the google apps update is breaking this.
After rebooting also, the device seems to remember the wifi state and tries to read the previous history and restore for the startup. And that is killing.
Any idea how to debug this or to wipe the wifi logs or to manually start the wifi/bluetooth radio.. ya athe bluetooth is also stuck.
Thanks guys in advance

Where is the fix?

Hi Can you please send a link for the solution? i am still stuck with "wifi turning on" screen and cant seem to bypass it. No matter what Stock image i flash through Wug Toolkit.

i have got the same wifi errorrigictsi vanished
initially i had loaded my explorer with fly rom and everything waas working except the internal memory. i'm not even able to download at least an app and then i tried bulletsense rom for increasing the internal memory of my explorer. it's successful, and the memory increased. From there onwards, the problem started. the wifi first said error... but after reboot, it's all the time saying "turning on"..
by typing "ifconfing twlan0" it said no devices found... so i thought it might be some driver error. coueld any one port some other drivers to the below rom so that i can have both internal memory and wifi...
link to bulletsense rom ///d-h.st/xFr//// ( add https before /xxxx/)
here is a screenshot of it...///bit.ly/MMSeam///
any one please help me on this and give me a chance to raise your thanks meter...
sorry that i'm newbie and not allowed to post links.

Hey guys.. I faced similar issue in my AMOI 820 based Indian local device Micromax (rooted + custom kernal)
I fixed this stuck wifi problem by uninstalling Google apps in system by removing them using Titanium back up + and again installing them from playstore if needed.. Hangouts(in my case) if it's a system app after getting updated is the culprit .. Try removing it and reboot and test it yourself..

guess it working now!!
I was going crazy about this stuck wifi issue!!
I tried everything!! I found on the advance panel on the wifi
That the MAC address and the IP address is unavailble.
After many tries i think i fixed it!! Using:
Busybox and MacMan
MacMan changed my MAC address and now the wifi is no longer stuck!!!! Hope it will help you too. Peace

WiFi association lost after reboot

This issue troubles me for long time now. Certain WiFi connections lose the security key after reboot and I need to reenter it each time which is very frustrating. I have noticed that this happens when an AP changes its SSID and key when it was previously connected to my phone with different credentials.
Note that a full wipe and factory reset doesn't solve the problem. My phone is rooted with custom ROM but the issue remains even across different roms.

[Q] Odd problem.... lose service after hitting power button/screen off

Hello all,
I've been searching for 3 days now and cannot find a solution to this problem. Normally I try to avoid starting a thread since there is usually one on the internet somewhere already, but this has me stumped.
I have a SGH-I337M on Bell, was running SlimKat 4.4.4 with no problems, and wanted to upgrade to LP. I first tried installing the CM12 optimized build, but it would never get past the boot screen. Then I tried GPE 5.0.2, and it looked beautiful and ran smoothly, but it would not automatically connect to Bell's network. If I went into the mobile networks menu and waited for it to scan, and then selected Bell, it would connect, but a few minutes later it would disconnect again. WiFi worked fine. Needless to say, having no constant service was unacceptable. After that I tried installing SlimLP (wiping cache, system, etc in between all installs) and had the same service disconnection problem.
Then I tried:
-flashing modems
-flashing back to stock from SAMmobile and reinstalling (where a similar problem persisted)
-starting from fresh to GPE, then starting from fresh to SlimLP
-reflashing GPE with all 3 kernel choices, cutting out as many installation options as I could
-trying different combinations of preferred wireless mode, APN, etc
Nothing works. I am back on SlimLP and I have got it to the point where the Bell service will work as long as the screen is on, but when I hit the power button and/or the screen goes off, the network disconnects again. If WiFi is NOT on, when I hit the power button and unlock the lock screen, it will automatically connect to Bell again, but this does not happen if WiFi is on.
Any ideas here..? I've read countless threads and nothing seems to work. Any help would be much appreciated as this is driving me crazy!!

The issue has been resolved! Apparently I was too impatient and was not using the proper modem
But I can't find a way to delete this thread. Damn I must be getting old

[Q] I9505 Lollipop - no internet - tons of "stopped" errors - Recovery: No Command!

[Q] I9505 Lollipop - no internet - tons of "stopped" errors - Recovery: No Command!
Hello again! After my wifi problem on Kitkat which was solved by reflashing several times (as suggested by a forum user ) I tried flashing to lollipop (5.0.1) which worked out perfectly, no problem this time. I flashed lollipop and rooted on friday and during the whole weekend everything worked perfectly. The phone was fast and smooth, no lags and no errors.
Today I woke up and as soon as I tried to use the phone I got tons of "unfortunately stopped" error messages. Things that give the error: Youtube, gmail, google,play store,bluetooth,samsung account, and a long etc. the camera does not work either and I can't connect to internet using WIFI nor mobile data.
As soon as I dissable mobile data and WIFI the errors go away, and everything seems ok. but of course without camera nor internet which makes my phone useless. (can only receive phone calls, which I tested)
EDIT: Seems like I found another Symptom/Error: I can't see the files in my Sd card nor the internal storage since I'm on a "fresh" factory reset System I only have access to the built in "My FIles" app and it shows "No files" on the internal storage, and does not even show the external sd card. I tried using an OTG cable (Which worked fine before all this happened) and it recognizes there is a usb drive connected but "My Files" shows the same: "No Files" even though the usb stick works fine and has several files.
Searched the forum but could not find this particular problem where all the errors come from turning on any kind of internet access (which does not work anyway, since besides the errors I can't connect to internet neither on wifi nor using mobile data)
I tried Factory Reset twice and as soon as it starts reinstalling the "system" I start getting those same tons of errors and If I try using my wifi password to connect to internet it can't go past the samsung account or google account step, it stays there giving errors on a loop. So I try setting up the wifi "Later" and it's able to complete the factory reset, but without fixing anything. No camera, no wifi, no mobile data, as as soon as I try to connect to the internet I start getting all those error and almost any imaginable app (of the freshly factory reseted S4)
I think I'll try reflashing it as soon as I get home from work, but would it help???
Any ideas?? has someone else had this problem before?
If reflshing does not work could I try downgrading to kitkat?
Did my phone died this time for ever???
