WiFi Authentication Issue: An Error Has Occurred

Look at the letters of your password, maybe you need to put them in uppercase because at first I entered them in lowercase and that’s where the error occurred. Then I switched to uppercase and it worked.

Hello,
regarding the Wi-Fi connection issue with the Livebox and Samsung Galaxy or any other device:
we had the following message “authentication error”
simply press the Wi-Fi button on the Livebox for 1 second, it should start blinking
for 10 minutes we can connect the device which will automatically pair with the box
there you go

An authentication error has been resolved. I had the same problem and I solved it in the following way.

Go to the box settings, for mine it's SFR, GO TO WIFI, then to Security, then change the key system to WPA/WPA2 Personal (PSK) and the key type to: TKIP AND AES
IMMEDIATELY YOUR SAMSUNG GALAXY CONNECTS TO YOUR BOX VIA WIFI without any other manipulation.

how to switch to WPE??

Galaxy Samsung core no Wi-Fi connections the mobile hotspot is disconnected help me

I have the same phone as you and the same problem :'(

Thank you, I had the same problem for a few days without understanding why! I just turned off and then turned my phone back on and everything is working again, great!

Hello,

Yes, almost 2 years have passed since your last post, lelf3569. But the problem is still relevant, as proof, this is what is happening to me right now, on this December 7, 2016.

So, in coming here for a solution, well, I found it:
1) by completely turning off my laptop and turning it back on, I did not get a positive result: this authentication failure is still marked there,
2) but when I pressed REBOOT and entered my code afterward, that's when everything returned to normal.

Great, right?

Thanks to the entire CCM community.

and also check that there is no MAC filtering enabled on the box...

There isn't any, because with my old phone, I could connect. I got the S3 today, but it had already been a week since I could access my router with any phone...

Hello. I have a Samsung S3 and I want to connect to the free Wi-Fi at the hotel where I'm staying during my trip. However, I can't find the place to enter my username and password. Can you please help me? Thank you.

How to know if MAC filtering is enabled and how to disable it?

I had the same problem with "authentication issue" and actually I hadn't entered the correct code, I hadn't used the capital letters. Once I did, it worked.

You just need to turn off the modem and turn it back on. I just did it and my problem is solved.

Thank you very much, awesome!!!
