Wi-fi authentication failure after going to official 4.1.2 - Galaxy S III Mini Q&A, Help & Troubleshooting

Good evening,
after going to 4.1.2 through wi-fi last night and after reset after upgrade my phone is not able to connect to home network due to "authentication error". Home network is working fine with other phone (S G Note) and with notebook. Never had issue with connecting.
Please help, this is aggravating. Thanks in advance.

Have you tried to "forget network" , toggle wi-fi off/on , and set up your network again?

Tried almost everything, did not work as it was probably not phone fault. Got different router, problem solved. Thanks a lot.

Wi-Fi Not Working (Nookie Froyo)

My wifi keeps cycling between on and off on my Nook. Sometimes it will stay on, and appear like it wants to connect to my wifi, but all it does is get stuck at the "obtaining ip address" portion of the process.
What do I need to do to remedy this?
I found the same problem, I can say that the Froya rom is almost perfect for me, except the problem that the WIFI lost and cyclical on and off. I tried many ways recomeended but no luck.
If someone can help to solve this please !!!
I had this problem before, and it was because of an improper flash. I skipped a step of wiping data and cache before applying the flash.
Settings -> Date & Time -> UNCHECK Automatic
that solved most of the problem for me.. its still unreliable, but atleast it doesnt get stuck in a loop anymore.
Maybe you should delete all networks registered on your phone. in case you have chosen to remember some WiFi networks in the past.
Then turn off/on your wifi network

Problem connecting to my network Please help!!

the weirdest thing happened to me, my phpne was working fine, i flashed fearkill fr13 after a full wipe coming from fr12 mcr.
It worked well for a couple of hours and all of the sudden i cant connect to my network. The only way it connects is by enabling 2g networks only and even like that i cant make any calls. I have even tried reinstalling the baseband 405 and nothing works...
My network is fine by the way, its just my phone
Please help me!!
Edit:
A little more info:
I tried a different sim card with the same results
Whenever i try to search for a network it just stays thinking for a while and does nothing
When I try to do it automatically it says it cannot connect to the network at this time immediately...
I managed to make a call on 2g networks only but as soon as i remove the check i cant connect
Edit 2:
Woooooow, this just gets weirder by the second!!
I can connect to the internet with wifi disabled and a clear X on the network as in no network connection... I can browse the internet just fine, NO CALLS though
... after countless Wipes and installing plenty of roms With no luck i gave up and as soon as i Woke up it Was Working again... strange but im happy
Guess it was your network after all
maybe, i had a blackberry beside it with a working 3g connection :S
And no idea how to explain 3g working with no bars and an x on it haha
O have problems with my network connection too.
In some rooms at my house I can get 3G access and in another room only EDGE.
Several times per day I can't get access to the network anyway. The only way to solve the probölem is to restart the phone.
Sometimes my phone tells me it is connected but there is no data transfer for several hours. I noticed that when I got home and many emails from the last hours appeared after being connected to my wifi.
I'm using the MCR but I've also tried the ROM from romkitchen-org. Changing the baseband had no effect.
I'll have a try with the stock ROM. If this would fail too I'll send my phone back to the dealer. I think it could also be an hardware defect.

Wifi No Longer Works AT ALL

My DROID Bionic's wifi doesn't work at all anymore. It was working just fine a couple of days ago. The phone got REALLY overheated so I dont know if that was the issue. When I go into wifi settings and try to connect to a wifi network it only says "Turning wi-fi on..." I was running the ICS leak .2233 at the time and FXZ'd to .902 and updated to stock ICS. Also, when I try to connect it also says "No nearby Bluetooth devices were found." Its odd because im in the wi-fi tab, not the bluetooth tab. I would really appreciate some replies. Thank you.
WiFi on mine stopped working in stock ICS. It would just continually attempt to grab an IP and then disconnect and reconnect. Forgetting the connection and reentering the key did not help. Oddly enough it worked fine in CM10JB. Not really wanting to mess with it I did a factory data reset (after backing up both ROM slots) and it started working again. It may have been heavy handed but it's going again...

WiFI Problem

Hi guys,
So I have JB and wifi isn't working. Sometimes it shows my home wifi and after some seconds it disappears. When it connects to my home wifi internet doesn't work at all. The problem started when I had CM 11 and I did hard reset but no results so I flashad stock rom and still having same problem. Is there a way to resolve this? Please help this n00b out.
I reseted my router and still having this problem.
And other phone are working fine with same network.

wifi keeps searching

hi all. i am on android 6.0.1 build 23.5.A.1.291. My problem is that my wifi keeps resetting and searching. i am traveling so its not my personal router that is an issue. my tablet and laptop connect to the same routers here without issue but my phone tries to connect various open connections but immediately resets all connections and starts searching for them again. occasionally it connects for a second. the same issue occurs if is set my tablet as a hotspot so i doubt it is related to the available connections. also for some reason i don't seem to have any advanced options anymore to tell the phone to sop scanning. Any help would be much appreciated. so far I tried turning airplane mode on and off as it seems have started at the airport, reset all network connections , general powering down and up etc. nothing seems to work.
hey, i know this post is quite old yet i only found it now facing exactly the same issue. it all started at my parents when phone was suddenly not able to connect (exclamation mark on wifi icon in status bar). i restarted router but it did not help. when i came home i faced the same issue. both routers are different, different provider, etc. before the weekend all worked fine so not really sure what happened. not the phone (z3c) keeps searching for wifi, displays the list for a few secs and searches again.
i tried what was suggested in other topics, like here:
https://forum.xda-developers.com/z3-compact/help/wifi-issues-z3c-marshmallow-fix-t3390859
or
https://forum.xda-developers.com/z3-compact/help/wifi-randomly-disconnecting-575-t3435244
but nothing helped. now considering to re-flash the latest firmware. trying my luck here before i do so.
current sw on 23.5.A.1.291
update:
1) i tried to repair the phone using Sony Companion .. did not help
2) flashed it with the latest sw .. did not help
in both cases sw version was D5803_23.5.A.1.291_1288-5411_R12D. when phone starts for the first time it shows wifi networks. but just for a while, that it starts "searching for wifi networks..". when i select my wifi network, fill in the password and click connect it says "failed to connect to network". i can already see on the background that the phone is again searching for wifi networks. if i try to connect at the right moment network is saved. but then it does not connect. or sometimes it does but "checking connection" takes ages and wifi symbol in top bar keeps appearing and disappearing. at the end it shows error message "could not connect to internet".
what could be the problem?
