[Q] Unable to connect to Wifi. "Authentication error occurred" - Galaxy S 4 Q&A, Help & Troubleshooting

Hello everyone!
I just got the S4, and im really impressed by it.
But for a heavy youtube user, beein unable to connect to my home wifi is a big problem.
Whenever I try to connect to my home wifi I immediately get the message "Authentication error occurred" and the S4 wants me to insert password again. I did manage to connect to the wifi for some breef moments using the "Wifi connection manager" application, but it suddenly stopped working after I put the phone to lock screen. I have updated the phone in Kies, Rooted it to maybe find some fixes, rebooted the access point, forgot and reconnected the network, and still no luck.
Here is some info on the wifi:
WPA-PSK (personal)
We use an access point for the wireless singals. This is a Moterola AP-5131
But considering there beeing 4 iPhones and 2 laptops already connected to the wifi, I doubt it beeing the AP that is the problem.
I really hope that there is a phone-side fix to this problem, because it is easier to hack into the Matrix than to acces the AccesPoint.

Hello Everyone,
I am not a professional or anything i am just a student.So kindly when you use the terminology make sure its understandable for a person with less knowledge about unlocking and stuff.
Ok here goes my problem, Its an I-mate Jasjar and its not turning on when i press the Power button. It shows USB on top and V1.00 when entering Bootloader mode. I dont know what am i suppose to do after that as i ran into a professional guy on msn and he showed me how to get into bootloader mode and he is too busy to help me out so i am here.
What i did was Its battery was low and i tried to Hard Reset it and now it wont turn on.
So any help is much appreciated

This is the Error i am getting when i followed Method 2 .
Kindly tell me what am i doing wrong i already Unchecked the USB connection in ActiveSync ....Whatelse am i suppose to do...please guys i really love this phone and cant wait to use it again.
Thanks.
ZODI.
hi ZODI,
you better kill the ActiveSync all together by using windows tak manager. I mean to kill the process called wcescom.exe on your PC.
Then reconnect your UNIVERSAL.
Wait a bit, then have a look in PC's Device Manager, if your UNIVERSAL was recognised and it should be listed within USB devices as HTC USB Sync or similar.
If so, then do a reflash one more time.
good luck
buzz
Hi ZODI,
you'd better kill ActiveSync all the way down, by using windows task manager.
- disconnect your UNIVERSAL
- kill wcescomm.exe process on your PC
- connect your UNI again and wait a bit
- check if display shows USB at the top of the screen
- in PC's Device Manager check, if the device driver (HTC USB Sync) was loaded
If all done, proceed and do a ROM REFLASH.
If not, you may also check at http://buzzdev.net/list.php?40 mainly those two sticky posts at the top.
good luck
buzz
Ok giving it a try ....hope it works this time and thanks.

WIFI Router will NOT work

Hey guys, i cannot get wifi router working no matter what i've tried. i just updated to the latest experimental version of the app and STILL it fails every time.

when i first start the app it asks for superuser permissions i allow and check the allow always button. so i'm 98% sure i'm good there. i have no idea why this will not work. any ideas??
Ive never had this problem, only when my phone was not rooted..
Hmm.. have u tried the regular stuff? Uninstall, reinstall, reboot, etc?
*This was posted from my Evo 4G using Tapatalkpro! Great app, if you want to browse and post through many dfferent forums*
Are you sure that you uninstalled the previous versions before you installed new ones? And if you installed a rom with it already installed, then used something like Titanium Backup and it restored Wireless tether, that can cause issues
yessir, i've uninstalled/installed every version of wifi router from oldest to current. i've also tried reloading my ROM 3 times with a different release each time.
the bizarre part is when i first got my evo i used unrevoked until i learned about full rooting and until then, my wifi router worked flawlessly. it's when i did the full root and nand unlock and installed OMJ's rom(with wifi built in) that the app quit working.
try this......
If you have root permissions, but still cannot start tethering, it may be an issue with either the tethering binaries or your tethering settings. From the main tether screen, try going to Menu->Setup->Menu->Reinstall binaries/configs.
when i hit menu from the main tether screen i get Settings, Access Control, Show Log and About.
So menu, then setup, once setup is open hit menu again and the option will pop up.let me know if it works.

Update your SuperUser Permissions app. ROM Manager has that, and you can find it on here.

"Unknown Device" after uninstalling Kies >.<

i hate Kies!!!!!!!!! it just died on me >.<
now when i plug the phone to the PC it shows up as "Unknown Device"
if i connect to another computer, then it works fine.
the thing was working fine until i tried uninstalling Kies to install a newer version of Kies
Kies is the worst piece of crap. It is incredible Samsung can not get such a simple thing right!
Sent from my GT-I9000 using XDA App
This is insane!!!!!!!
it suddenly started working properly now, without doing anything on the computer
now it properly identify itself as Android device instead of an "Unknown Device"
Kies and it's crazy ness
i did not even reboot the computer
Screenshot of Kies working when it feels like it...

i found the solution for the problem ...if you are using any of launchers from market launcher pro or awd launcher u need to switch back to stock launcher and restart the phone after u reboot the phone with stock launcher simply connect ur phone to computer after that ur pc should have no problem finding ur galaxy s ,np
Why does it say: This device's version cannot be updated?
it's not necessary to reboot the phone
just run TwLauncher and it works right away, as long as the USB in the phone is not set to Debug mode.
The problem i was having was with Kies and USB port in the PC

It doesn't appear to be anything to do with the phone itself.
I just plugged my phone in and got the "USB Device Not Recognised" error message.
I unplugged the phone and restarted it, but my computer is still flashing up the "USB Device Not Recognised" error every few seconds - without the phone connected!
I think the USB drivers are seriously flawed. I'm sick of reinstalling them just so I can connect my phone, which has become my standard way of resolving the issue.
Either that, or I've had to completely uninstall and reinstall Kies, a number of times, which usually works for the first few times I plug the phone in before failing again.
Pain in the ass.
I'm sick of this - and I'm kicking myself - as I suspected Samsung just didn't know how to provide software, based on lots of stories that seem to float around online about them.
I wish I'd stuck with HTC now.
fyi, I'm running Windows7 64bit, which seems to be a common platform to have problems with.
i only use Kies to check for Official ROMs downloads
i don't use Kies for anything else
all my syncing, calendars and contacts are handled online on Google

Yeah let gmail sync everything but in 2.1 we didint have this option,or maybe I just missed

How to Reset Samsung Foucs

Folks,
I got a new Samsung focus (Re 1.3) yesterday , followed a tutorial from youtube to install custom rom. Everything went good , like installing MAGLDR and later reset and installing ROM. After installing ROM, the guy told that teh SAMSUNG logo appears for a long time and we have to poweroff by removing the battery. I did the same but nothing was working on my mobile. It starts booting shows samsung screen and stucks at the following screenshot, i tried to connect it to laptop as it showed in screenshot,but even hours dint helped anything. Now i can only see the download mode , not even the format mode. I searched how to reset to factory setting, but nothing was found useful. I found two posts one with instructions and files are corrupted, one post with files but no instructions. please help me with this.
​Thanks,
WY.

Flash a stock rom from here (UCJK2 for Focus revision 1.3 / UCJK3 for 1.4).
Here's a flash tutorial.
Thank you very much for your help.. but some reason my mobile was not detected in the loader..everything was green but Start button is disabled and the mobile was not shown in the ports section.
Some how i am able to start it in format mode cancel and it went to magldr cmd..installed everything and this time works perfect.
Appreciate your help but i still dint get why start button was disable.

To "green" the port in the flasher, unplug the USB from your comp, wait about 2-3 seconds and plug it back. Just before flashing (after all are loaded).
As EnderPsp said u should always start the downloader first and then connect the phone in download mode.
i tried either way.. first attempt i connected mobile after loading the files as said in tutorial.. but start button was disabled and the mobile is not shown in ports section of the flasher..but it was shown clearly in system bar that mobile is connected and even safe remove was showing the mobile name. sorry to ask so many questions, its just in case it will be very useful for others in future.. thank you very much for your valuable replies.

Right click - uninstall, reboot, reinstall drivers.
Same problem here!
My G2 is recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB icon on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definitely there seems to be a problem with the phone, but I don't believe it's a software but a firmware problem.
Please help if anyone knows what to do.
