Authentication Error Occurred connecting to WIFI

This is a warning for Samsung devices! If you continue to get this error while trying to connect to your Wifi router, and it appears to not even attempt to actually connect to the router each time there is a simple solution. The error that will show is "Authentication Error Occurred" You can get closer to your router but it will not fix the problem, unless you actually have a different problem. This week I have had this occur on my Galaxy S Vibrant (Rooted with SlimBean ROM) and my Galaxy Note 10.1 (Stock latest version).
Solution to the problem (problem may be with installation of non-default launchers(For me it was Kid Mode a game for my kid))
Step 1 -- Intentionally put in the wrong password to access the router..
..it will of course fail...
Step 2 -- Put in the correct password. :fingers-crossed:
It will reconnect like new.:highfive:
This is what worked for me, and if you have the same problem (really no matter the Samsung device) it should work for you.
For whatever reason putting in the wrong password makes the device actually attempt to connect again. I had tried everything from placing the device on the router, resetting the router, restarting the devices, removing apps, factory resetting one device( which worked after two resets on the non-stock Vibrant), forgetting the network, turning off sleep mode in advanced wifi settings, adjusting all sorts of other settings.
Thought I would share my solution and I hope it helps more than just the Note 10.1 community if this occurs to others, which my google search results showed me it does and on many Samsung devices...which makes me sad, because I love my Samsungs.

Funny you should mention this.
I had the exact same error this morning on my 8020! I just reset the router and all good.

That is what my sister does on her S3 (resets router), but for some reason this works if you cannot reset the router... (its in use by others). Next time you have this problem (if you do again), let me know if this works for you?
Also I was thinking an app that I installed caused this problem, do you think you have anything on your 8020 that would cause this? (such as a childs game that blocks certain actions from occuring, or a firewall app)

You could also "Forget" the network then rescan... I've done this before too...

No idea. I havent installed anything different or done anything out of the ordinary. It hasnt happened since but it happened first thing when woke up.

are these the best solutions found? because i am having this problem, and none of these solutions have helped. and i know it isn't some program causing it, because I have wiped my i900 clean four or five times, and get it upon setup, before anything is even loaded on it yet, except the rom. so if anyone has anything else, please chime in.

I have this problem too and it's the craziest solution, but all I have to do is open up my laptop and open up a Web browser then magically my note 10.1 or my gs3 connects right back up.. So I don't know if it's some kind of interference or what? Rebooting my router also works. I haven't tried entering wrong password though but I will for sure try it next time since it means I won't have to pull out another device.

This issue is driving me insane! It did happen before and I've tried the password solution...it didn't work.
This happens every so often and it is quite annoying.
Has anyone found any fixes for this yet aside from the reset router or password solution?

was having same issue on my note2, both stock and roms, here is what I did and finally fixed it. Had to adjust the wireless settings on my router (dlink 645):
802.11 set mixed 802.11n and 802.11g
do not check "enable auto channel scan"
wireless channel: I set to 2.462 ch11
channel width: 20/40Mhz auto
security: wpa-personal
wpa mode: wpa2 only
cipher: tkip
hopefully this helps.

Here's my problem: (I get authentication error when trying to connect to wifi)
My Nexus 7 tablet and my friends laptop connect just fine but my Samsung Galaxy S3 won't connect
The SSID comes up and it says excellent or very good signal strength (in same room as router)
Previously, I had an S2 and it connected with no problem
Tried changing frequency band: 2.4 only, 5 only and auto (none work)
I can't play around with the router - it isn't mine and works fine for other devices.
My S3 works fine on my home wifi and several other places I have gone
Any ideas? Thanks

Assigning a static reserved IP for the device might help

First thing I always try is pulling the power cord for at least 30 seconds, reboot the router, and it usually works.

Thanks for suggestions. I'll try rebooting first, of course but I am not at my friend's house at the moment.
I don't know anything about assigning an IP address. If that has to be done to the router, I can't touch it.

[Solved] Router Reset Signal
My Samsung Galaxy 4 and my husbands Samsung Reverb were both throwing Authentication Errors every time we tried to connect using the wps pin, the wps button or the passcode. Nothing was working, to include trying incorrect password followed by correct password.
Hubby called Comcast and had a reset signal sent to the box. After the reset code was sent and the box cycled off and then on, Comcast verified the ip address once again and we pushed the WPS button for a fresh try.
WPS claimed to have failed on both phones but promptly connected. Problem appears to be solved for now so I don't care if the phones tell me that they're sucking toes! As long as they connect
I'll update if any further issues arise but for now I suggest calling your wifi provider and requesting that they flash the box (send a reset signal).
Good Luck!

access control list

Had a harrrowing experience solving this.
Was trying to connect wifi to note3 but it was seemingly stubborn in giving authentication error.
Had tried resetting the device, even changed router settings and yet it does not budge.
At last it dawned on me to stumble on access control list. In router settings there is option for setting access control for the devices used. Once the devices are added and the access control is turned on, it does not allow any other device to connect even if the credentials are correct.
So, once I have unchecked the access control list in router settings, it connected instantly.
I must have realized the same. Being oblivious of this fact costed a day.
Hope this helps.
Thanks,

connecting to wi fi with tablet
We had a tablet that previously logged onto our Wifi but after taking it to school and returning home it wouldn't reconnect at home and asked for the password. I think we may have put the wrong password in too many times then even when we use the correct one it wouldn't connect.On the advice of our data provider we changed the name of our Wi Fi router in its set up and suddenly we could connect again when entering the password correctly. Worth a go if you have put the wrong password in too many times or your tablet just won't reconnect or even forget the connection.

I got this prob with Note 10.1 today and then after connection, dropping wifi and reconnect every 10 mins or so.

802.1x EAP issues

My school(Umass Amherst) uses 802.1x EAP protocol, and I'm having issues connecting to the network. First off I had no issues connecting to the network with my htc one and cm 10.1. The oddest thing is when I first booted my Nexus 5 it connected to the network WITHOUT me even entering in my username and password. However, after unlocking the bootloader which reset my phone I cannot connect to the network. I've tried using the school's step by step method which uses an app called xpressconnect. No luck. If anyone has any insight, it would be much appreciated.

Arg... this is so frustrating!!! I have tried every possible angle with this. I absolutely need to be able to connect to my school's network! I'm going to have to return this amazing phone if I can't solve this

Hey, at the college where I work, we also use 802.11x for authentication and I haven't had an issue with my N5. We also use XpressConnect as the wifi wizard but I just manually set up my connections. I have tried our staff and student wireless networks without issue. The settings are the same but we adjust access based on where your college id is located in AD. I haven't come in contact with another N5 yet.
One thing I do when I can't get student devices to connect to our wifi, is I reset their password to their default password, even if it already is the default password. No clue what it does but devices connect right away-you might want to try going to your school's help desk / IT department and ask them to reset your password or do it through the college's website if thats available. Sometimes, just a password change enables devices to get on the network.
Hope it helps...

Nexus 5 WiFi 802.1X EAP (PEAP+MSCHAPv2) Not connecting

I've been trying to connect to my college's wifi for the past 30 minutes and I still can't seem to get it to connect. I copied the settings straight from my Nexus 7 that is running 4.2.2. I might install a custom kernel right now and see if it alleviates this problem.

Does ist?

Nexus 5 android L factory image same issue, i tryed with every version of the preview and official image and doesn't work.
With kitkat work perfectly and custom kernel don't solve the issue

I flashed yesterday the official build and it doesn't connect to a network like the one you described. I guess they need to fix some things, this is not acceptable.

I have the same problem on Android 5 on my Nexus 9. But my Nexus 5 (upgraded from KitKat, not freshly installed) connects fine to our work WiFi (PEAP).

Really? Wow, but i cant believe that nobody had the same issue while preview.
Do you have the MASCHAPv2 Authentifiaction?

Hello guys,
I can confirm this has been happening since the "preview version" on the Nexus5, we've the same configuration (PEAP+MSCHAPv2) and we've the same issue with our wireless network with these devices.

But why doesnt google know it?

I posted that logcat with my friend

I've tried to configure our Wireless LAN Controller with WPA2 EAP-TLS+CCMP support and this configuration it's working well for our Nexus 5 devices. I don't know if you could configure your wireless network with this encryption support but you should consider it.

I know nothing of these wifi protocols but what I noticed is I cannot connect to networks with secondary login on a Web page.
I am freaking out... All networks at work are like that and cannot connect to any.
This started happening yesterday after flashing the 5.0 image.

Hello Steve,
That's the same issue that was affected to me until that I tried to use WPA2 Enterprise with EAP-TLS+CCMP encryption for our Nexus 5 devices with Android 5.0. Would you be so kind as tell me about your wireless access point model and manufacturer? I could try to explain how you can configure your network in order to resolve this issue or at least say if this configuration is possible with your wireless access points.
Regards

Will get all the info I can but I am working night shift so it will be hard to get info. Access points are all like 30 feet high so I cannot just take a look. What I know it's a Bell Canada network if this is any help.
One thing is sure is that the network will not be reconfigured for me to access it. I will need to adapt to the network. All was fine on 4.4.4.

I understand your situation but the PEAP-MSCHAPv2 is broken now with Android 5.0. I think that your unique option if you don't want to change nothing in your wireless access point infrastructure, is perform a downgrade to 4.4.4. This is obvious, I know.
Anyway you should consider to study change your wireless security to EAP-TLS+CCMP in order to avoid some issues inherent of MSCHAPv2 protocol related to some protocol vulnerabilities that could permit to attack your wireless network with a brute force attack.
I'm not familiar with Bell canada Network but it's possible that you have a wireless lan controller in order to centralize your wireless lan management, probably that wireless lan controller have information about your access points.

That seems to be the problem.

Yeah... I can confirm that these issues are only with FLASHING factory images. I tried that and it didn't connect to my work wifi (CISCO routers). But my friend did OTA update. Its working fine for him.
I think there is some problem with factory images. Going back to 4.4.4 for now, and will do OTA.

I tried following:
Flash 4.4.4 Factory Image.
Wipe Data and Cache.
Sideload OTA 5.0.
Wipe Data and Cache.
But I cant connect to eduroam WiFi. MASCHAPV2/PEAP.

I actually flashed the factory image. But without wiping everything aka. dirty flash. Connecting to the WiFi at work still works great.

that may be the problem. i completely wiped the system. and its not working for me. dirty flash is more like OTA right? but manual, may be that previous settings are making it to work. when completely wiped.. its not able to connect.

Remove "pmf=1" from /data/misc/wifi/wpa_supplicant.conf and reboot, wifi works. Root required.

WiFi problem

I've noticed WiFi problem in my moto g 2015.

Did you manage to resolve your wifi problem?
I bought the Moto G (2015) 2GB RAM / 16GB ROM for my wife and she's having problems with the home wifi. It often says there is a "connection error" and loops to try to connect again and then fails. Her work wifi seems to function ok.
Having read about similar problems with older moto gs, people recommended (1) turning on and off airplane mode. (2) changing channel number of router.
Both sometimes work and sometimes don't. But it's not really a permanent solution. I'm a bit reluctant to do a factory reset and reinstall everything if it won't resolve the problem. The device came with the latest firmware already installed (5.1.1) and I haven't rooted or unlocked bootloader so should be a pretty clean install.
Anyway, would like to hear that factory reseting could resolve this issue or not before trying.
Thanks for any advice!

Mine does it every now and then. I just unplug my router, wait a minute, plug it back in, and then it connects.

Yes. It works for me too. But what happens if you're on a public or work wifi where you can't reset the router? It doesn't really seem like a long term solution.
Is this a standard problem with this phone? Anyone else have a similar problem or preferably a solution?

Yeah resetting other than home router is not the answer. It's an Android issue as all my phones do it from time to time. I haven't been able to figure it out. The other "fix" if you can't reset the router is try going into the Wi-Fi settings, and forget the network/name, and then add it back as new. It takes longer, but it could work for you. That's how I get around it when connecting to work when it won't auto connect.

Hi, I had also faced the same problem with a open wifi network which is free for 15 mins ..
Other than that one ..i had every router connected to my phone..
I was thinking the problem is not in your phone.. It's in router which might be old ��
Because old routers will have 802 a or something which are in compatible to some phones..
Or the router is not allowing your phone to get connected.. As your phone is latest and it has advanced protocols inscribed in it..
Do one thing.. Shed some light on this now :
1) router model (if known to you)
2) phone models which got connected to that router and it's operating system version (like 5.1.1)
And there is also one more point.. I found our phone might find problems connecting to 5ghz band router ..while it works fine for smaller routers like 2.4ghz
We can decide when you dig some info about the questions I mentioned...
We will get answers

Just turn off wifi and then turn it on it will fix the problem

You would think it would be that simple, but it's not. It just sits there "Connecting", then nothing, then "Connecting". Keeps cycling like that.

My router is a netgear CG3100Dv3 (using WPA2-PSK [AES] encryption) and uses 2.4 GHz. I don't think it's the router's fault though because I've had many friends connect with a variety of phones and none of them have had the problem before. I currently have a Oneplus One (android 5.0.2) and have used a Nexus 4 and Samsung Galaxy S (1) on this router without problems. Maybe it's a problem with android 5.1.1 as I guess not many of my friends have it yet. I've written to motorola support but they still havent got back to me.

Strange. I've never had a problem before with wifi. Maybe I've been lucky until now. Yep - have tried forgetting and reconnecting to wifi signal. Again, a temporary solution that will quickly become irritating when there shouldn't really be a problem for such a simple operation.

It's a temporary solution but a pain in the arse if you have to reset the router every few hours. And as I said before, what happens when you can't connect to a router which you can't reset? (i.e. public, work)

Change the router's channel, then refresh the wifi in the phone.

Firstly i agree that our Moto G has some kind of issue with some routers.. but there will be solutions for them from the ROUTERS POINT OF SIDE to make it work
i have read about your router .. Things i suggest (if you have already done them then let me know )
1) your router has option to change MODE to get speeds more than 150mbps.. try changing that 802.11 MODE , restart your Phone and Router and also keep CHANNEL to AUTO , try changing the security WPA to others also..
2) your Wifi of your phone will have a MAC address , copy that and paste in your Router to allow this device..
i am still finding info on your problem..
the reason why i think your Router can solve the problem is : i had once read about 802.11 b/g/n/ac types.. i am getting a doubt that they are the ones causing the problem.. if you are aware of it
have a look at this bro once : http://www.smartmobilephonesolutions.com/content/cant-connect-to-wifi-on-android-smartphone
in this he said that Wifi fix apps can solve the easy problems..:highfive: , hope you find solution

Hmm. That doesn't sound promising. Will they sort it out with the next firmware update? Are motorola even aware there is this problem?

Ok. Will change channel to auto mode. It was already on "up to 300 Mbps". Will also put MAC addresss in the router.
However this still relies on having access to the router. What happens when you don't have access. If this is going to happen on many routers then I prefer to return the phone and buy one which never has this problem.

I'll give a wifi fix app a go to. But they just seem to automatically delete known wifi SSIDs and passwords.
Another option would be to root and install new ROM and radio, but would prefer not to.
It seems like a lot of Nexus 5 users on 5.1.1 are having wifi problems too:

Anyway, thanks for you advice!

Just a quick update if there is anyone else reading this thread with a similar problem.
I changed the channel mode to auto and that has seemed to fix the problem. The moto g seems to connect without problems now. I didn't enter the MAC address nor used a "wifi fix" app so far.
Fingers crossed...

I have the same problem. Wifi just stops working and had a ! Symbol beside the wifi icon. I have probably had a 100 phones and devices connected to this router without a problem. I have changed a bunch of settings the router and it didn't help.
Disabling wifi off then on works, but that is no solution. I will try anther Rom or kernel. I am on resurrection 5.1.1

I have the same problem. Wifi just stops working and had a ! Symbol beside the wifi icon. I have probably had a 100 phones and devices connected to this router without a problem. I have changed a bunch of settings the router and it didn't help.
Disabling wifi off then on works, but that is no solution. I will try anther Rom or kernel. I am on resurrection 5.1.1

My problem was slightly different in that the phone wouldn't even connect to the wifi signal. It would cycle continuously between "connecting" and "authentication error".
Does it work with other routers?

Thanks for your help! I'm still a little wary that the phone will have problems in the future on other routers, but it's a good enough fix for now. Hopefully a later firmware update will sort it out.

Unfortunately, my wife took the moto g on a business trip last week and could not connect to any wifi signals (her colleagues did not have a problem).
Not sure what to do now. I'm in contact with motorola support but they don't have any suggestions yet (apart from blaming the router - which has never had a problem with any other devices!)

Well I just emailed Amazon and they're sending a replacement. Hopefully this will solve the problem

Wifi Issue on latest CM13 nightly (but not with my Moto G)

So in short I cannot connect to the campus wifi network with cm-13.0-20151204/05 on my OnePlus one, but I can easily do it on my MotoG (cm-13.0-20151204). If I try to connect to it from the quick settings, it brings up the set up wifi screen, and when in the settings it just says "obtaining IP address" constantly. I tried just typing in the wrong password and it comes up with 'Wi-Fi Connection Failure' as expected, so its definitely not me using the wrong settings.
Obviously since its the campus wifi, I can't go ahead and check the settings, so I was just wondering if anyone had any advice/knew wether it is a known bug. Thanks in advance

Found a solution for this exact thing happening to me. The solution was for the Nexus 6, but it seems to be a Marshmallow issue.
