    i had the same problem, BUT it was because I logged into my router. once i logged into my router through the internet, it reset my password. so i had to go into my router settings and change the password again. hope this helped. :-)

    Either this is a "feature" of enabling remote admin on your router or you need to upgrade its firmware. I've never heard of a router doing this.

    Oddly, I have this error when I'm up in my room where signal is low, but as soon as I get close to my router, the problem goes away and I can connect with full signal. I don't know what causes this, but it's annoying. I'm a Nexus 7 user, by the way.
    Then it's probably this Android bug: Issue 36993 - android - wifi no longer working in ics 4.0.4. The issue is driving me nuts too and unfortunately Google seems to ignore it since September 2012

    (Maybe you also want to vote it up a little bit in Googles priority rank with the star at the left of the issue title.)

    Bingo!

    Firmware update for my many WAPs worked for me.

    Netgear WAG102 was recently purchased in bulk, but the firmware residing on it was from 2007.
    Now our htc one's (android 4.1.2) are blazing.

    I have the same problem on my SGS2 after upgrading to 4.1.2 - it is a known network, the password hasn't changed. It later connects to the wifi after a while. It doesn't help forgetting the network and reconnecting. It must be a bug on 4.1.2 - any solutions yet?

    I had the same problem with my wife's Galaxy S4: 'Authentication error.' I tried several things, reentering the WiFi password, shutting off and restarting her phone, no luck. I finally fixed it by resetting my router. Try unplugging your router, waiting 10 seconds and plug it back in. That should solve the problem.

    This was happening to me at my workplace. I went to advanced settings for my work wi-fi and modified Dynamic IP to Static IP. So far this has worked me and I have yet to disconnect/unauthenticate. Nexus 4 user.
    So far so good. Seems to have solved the issue. Tested in one of the areas that gave me the disconnect/unauthenticate error.
    Ran speed test app and it did not drop WiFi and I got a 27mb download result. That has never happened in that area of my house before.
    Many thanks!

    hi i had the same problem wifi autentication error, i did all the things in this post and nothing! But, i found the solution in google play!!! Download wifi fixer, then restart your router and open the program in order to connect to wifi, in the last window found nearly wifi and choose your red, nothing more! Good luck!
