[Q] Unable to connect to Wifi. "Authentication error occurred"

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.

why would you change wifi permissions to that?
How they are after reboot is correct - the file and folder should be rwxrwxrwx - anything else you are risking it saying error when you turn on wifi
because you are seeing wifi networks its unlikely you are using the wrong wifi driver as that would mean it would just say scanning and not show wifi networks
I assume you can select a wifi network and enter in the key
I will also assume that you are actually entering the correct wifi key
I will alsso assume that it gets stuck obtaining ip address
Therefore you have six choices
1 - To reflah the kernel
2 - To change kernels and see if that makes any difference
3 - To set a static ip address to see if its a dhcp problem (you can get ip address details from the router settings or a computer connected to the network)
4 - Remove droidwall if you have it
5 - Change the permissions of system/etc/dhcpcd/dhcp-run-hooks to rwxrwxrwx (turn wifi off then back on again)
6 - Delete the file data/misc/dhcp/dhcp_list (then restart phone)

[N 6P][H1512-Int.][LTE Problem]tinkered around with hidden menu,cant connect to LTE

i have a rooted nexus 6p (h1512) (the international version) with a custom rom (pure nexus rom) and custom recovery...after rooting the device i foolishly tinkered around the hidden secret codes on my device..i downloaded an app called shortcut master (lite)....and searched for some hidden codes...i selected a code 3282 from the options....went into dataSettings, then into lte // edit///(i knew the msl code 000000) and tried to enable band 26...the reason i did that was because i was using an lte sim card and was not getting proper speeds...so i figured enabling a band may make a difference...besides i thought..i could always revert it back...as soon as i enabled band 26....the phone restarted and now i cant get the lte network (no bars)...i went back to the hidden menu to revert the settings but the settings there were exactly similar as before( band 26 was still disabled) ...i cant see any changes that my fooling around had done..and even though i cant get any bars with lte sim....the apn settings associated with the sim are still there..
and i also inserted other 3g sim cards in the phone ...they work perfectly okay...so i think it has something to do with lte bands....i have also flashed the stock factory image from google after this problem after wiping everything, but that didnt solve the problem....i then reflashed the radio too....but it didnt help...so then i went back to my custom rom
is there any way that i can reset the changes i may have made?
any help will be greatly appreciated..
these are the current lte settings on my phone( there is no difference compared to when lte sim was working)

is there any way to reset lte settings?
i think my messing around with these hidden codes has changed some underlying deep seated huawei modem firmware settings...
i just want to know if any of you guys know how to fix this problem? any help will be greatly appreciated.
Edit : All non lte sim cards work just fine..and yes, i inserted that lte sim in other phones and it works just fine, so the sim has no poblem..
EDIT 2: SOLVED...after much searching for solution, bet all my cards on efs partition restoration, was successfull...anyone having similar problems , pm me if u wanna know the commands for nexus 6p to erase efs and its restoration.
CHEERS!!!

Having the same issues on my wife's phone hopefully someone finds a fix.

Had the same issue, download netmonster from market and go into phone info, then turn off cellular radio then turn it back on. Worked for me

Problems with other operators s7 verizion

I ve bought s7 in Asia. And i didnt know that its a big problem that it is a verizion version. Now all the time when i travel and changing sim cards i need manualy to add Apn point to use internet and not all people who sell know this details. (Usually when u buy sim and insert it this settings are alrready inside u just have to send message or choose apn point)may be there is some custom rom which will help with it?and the most important problem which i didnt solved yet happened yesterday. In Thailand i ve bought new sim. And to activate 7 days internet need to send code starting from *9 or to check internet balance *900# . But it's not possible to do!!! Because whatever u will type starting from *9 u will get a message something like "forward calling type US number" so yesterday i spent 30 minutes trying to apply this internet. And nothing helped,I also look the code *72 or othet to switch it off. Not working. Im so disapointed with this verizion. I want to get rid of all this codes *9 and in other unlocked galaxy phones i could choose mobile network in settings(lte,gsm) or choose operator. Here it's happening automaticly.help me please,because i cant even use this normal code which starting from *9.. all the time this stupid message with call forwarding

Try flashing the 930U firmware to the phone. It will flash it to the US Unlocked version. If that doesn't help maybe just sell it and get the 930F international version.

All phones I have that are carrier specific you need to enter APN settings manually. APN settings aren't attached to the SIM card, especially if its a prepaid one. I normally get the APN settings online or from the store I bought the SIM card or I know there are a few apps out there with APN databases for countries/carriers

You can choose what network to connect to but APN settings are needed for data only, not voice. Under settings > mobile networks > network mode > choose GSM > Manual > then at the bottom you can choose the network operator

Lenovo k6 note recieves calls, but does't make calls or use data!

hello guys,
I rooted my phone, and since the moment I rooted it. it put a dash on my sim card sign on the notification bar. although when I lock the mobile I see my network operator appear on lock screen.
the phone receives calls and doesn't make calls. and also one other thing I noticed is that I can't allow apps permissions from the message box that appears in app. I need to go into settings to enable them from settings.
help me on this
as u can see in the screenshot, it says Vodafone in lock screen and sim card slot is empty in notification bar, so it recieves calls, and doesn't make outbound calls or connect to data.

So no serious issues. Just OS has some problems. Try factory resetting it. Else download stock firmwsre and flash it. Dont downgrade if you are doing that. You will loose your baseband.

could you refer to the most trusted source on how to flash stock firmware please. I always try it and fail.
