Help Wifi Authentication Error Occurred - Galaxy S3 on 4.0.4

Solution:

I have a Note 2 and this same thing happened to me right after the 4.1.1. update. Here's how I fixed it:

• Get on your PC and temporarily change your router's key.
• Connect your phone and PC's wi-fi with the new key.
• Change it back, and connect with the original one.

Works fine now.

I have the same problem. I cannot to my own wifi. It sometimes say incorrect password. Sometimes it says authenticity problem. If there is a solution please I need help

I have a Galaxy S3 with 4.1.1. Android Version and I started experienced the error issue after upgrading from the prior version.

The "connection" error showed up sporadically against my Netgear N Router with WPA2-PSK security around the house. After further testing, this is what I found out.

Without changing my phone settings or the router's, I stood up directly in front of the Wireless router to do the following:

On the phone only:
1) Forget the connection
2) Turn off WIFI
3) Turn on WIFI
4) Let the phone scan the home network
5) Reenter security password

After that, I got a valid IP address and the phone stayed connected around the whole house.

My guess is that there is a bug on the new Android version where the signal threshold gets corrupted during synch intervals. Did Google lower the standard on software reliability? I hope not and that a software fix be done soon.

CharlieMX, Thanks for that. After day of frustration it worked for me nice one.

Hi all,

I have a Samsung Galaxy S3 that was originally on firmware 4.0.3 (what was shipped with the device). Everything was working fine, I was able to connect to my wifi at home no problems.

I received an OTA upgrade to 4.0.4. Ever since then, everytime I try to connect to my home wifi, I get the "Authentication Error Occurred" message. My router settings have not changed, my password has not changed - all other devices in my household are able to connect to the wifi without any issues.

I have tried rebooting my phone, rebooting my router. I have also tried factory resetting both my phone and my router - no luck. My wifi has a WPS function - I also tried using this without any success (no authentication error occurred message - just times out when trying to use the push button or pin technique).

I have disabled mac address filtering, firewalls etc. the most bizarre thing is, i turned off my router security (i.e. no security settings) and i STILL get authentication error occurred message.

The weird thing is, it seems to work on some routers and not others. I am able to connect to my parents wifi, and my friends wifi, but not my own, and not at my work (was previously able to prior to upgrading to 4.0.4).

Another weird thing - my router is dual band - 2.4GHz and 5GHz. I am able to connect to the 5Ghz band, but not the 2.4Ghz band. Using 5Ghz is not an option for me though, as the range is quite poor. I need to be able to use the 2.4Ghz band.

I'm at my wits end, I dont know what else to do. Does anyone else have this problem? Has anyone had any luck fixing it? Does anyone have any suggestions?

Hey Guys,
Usually "authentication error" error messages refer to a type of second level of security in addition to the pass phrase you've assigned to your wireless router especially if the ‘wireless access point’ is enabled. In this case your galaxy s3 will wifi connect to your computer with the pass phrase but stop short at the wireless access point to return the ‘authentication error’ message.

To fix this, you will need to enter the MAC address of your galaxy s3 in the “wireless station access list”. First go to your galaxy s3 settings page and press ‘about device’, press ‘status’ and scroll half way down and take note of the Wi-Fi MAC address.

Go back to your computer and log back in to the router and navigate to the ‘Wireless Settings” page and click on the ‘Setup Access List’ button. In the ‘Add New Station Manually’ area, enter a device name, enter the Wi-FI MAC address without the semi colons and click ‘Add’. Your Galaxy s3 device is now listed in the table of ‘Trusted Wireless Stations’. Ensure that the check box for ‘Turn Access Control On’ is checked. Click ‘Apply’ and log out.

As I use a netgear router, the wireless settings pages may be slightly different but the words should be similar.

The ‘authentication error’ message should not appear again.

Authentication Error Occured: I have tried all the forum suggestions. Does not matter if iam trying to connect to the local coffee shop free wifi or my work wifi.. did all the suggested router reconfigurations..not a single suggestion has helped me. This seems to have occured around the time of the recent Verizion update if not a little before.

Same for nearly every Android users who upgraded to ICS or newer..

I have also tried everything I could try, that including hacking my GS3. Someone on the bug report I've opened LAST SEPTEMBER (!) on Google Issue 36993 - android - wifi no longer working in ics 4.0.4 - Android - An Open Handset Alliance Project - Google Project Hosting has mentioned that Samsung replaced a component in his Galaxy S3 because defective. I wonder if its some kind of generalized problem that would affect everyone? Perhaps a component that failed in the phone?

It took a while but I managed to get Samsung to send me a prepaid label to send my phone for repair after that person on my bug report mentioned they repaired his. I received the prepaid label, but about a week (when I was just about to send the phone) they cancelled the service ticket!! Since then, they no longer reply to my emails..

Maybe I was just unlucky (so are thousands of customers) but IMO something is REALLY fishy... really.

My guess is that it wont last very long. I certainly hope the opposite but I have tried this a while back and next day I was back at square 1.

I solved the authentication problem by re-entering my Network Key (rather than my password)

By network key what do you exactly mean? All I have in my access point is a "Pre-shared Key"which all wireless devices are gladly using without a single glitch and its always been like that except for this samsung garbage phone...

I dont know what else other than your wifi password (or pre-shared key as its called by Dlink) you entered on your phone..

I was experiencing the same issues, tried all suggestions listed on various forums, I was even given a replacement handset and the problem still persisted. I then decided to purchase a new router, googled which router was best for the handset and came upon a virgin media thread where I found the answer. Our existing router is old and was set to WEP security - this handset does not support that setting. I have just changed our router settings from WEP to WPA personal/AES+TKIP entered a new pass phrase and my phone logged in straight away, all I then had to do was re-login all other wifi devices. Hope this helps

Not being an IT guy how do you do this? Routers for dummies please! Thank you in advance!!! I have an Arris Router, Network Name (SSID) Encrypt WPA/WPA2 - TKIP-AES. I really don't know how to change anything you guys are saying? Heeeelp

i am having the problem... its happened with my ASUS transformer too! it happened all at the same time... including my laptop! all my other devices work!!! and the ones that dont work, work at my parents house and everywhere else, except for at home! i have tried everything!!!!!!!!!

I had same problem after i upgraded my S3 to 4.2.2, I tried everything possible but I couldnt connect.
Then I went right beside the home router and did exactly as below:
On the phone only:
1) Forget the connection
2) Turn off WIFI
3) Turn on WIFI
4) Let the phone scan the home network
5) Reenter security password

So, I think after new update the phone software still hold on to some settings from the previous version which are conflicting ... or the low signal reception as pointed out by some members.
The bottomline is, going by this method fixed the problem, and my phone has been connecting very well since then.

For galaxy S3,

Did the 'in front of wifi router' steps, and additionaly this:

You could maybe check for WiFi power saver mode:

1) *#0011#
2) menu (left) key
3) WiFi
4) Check if WIFI Power Save Mode is ON -> change to OFF
5) back, back, back

Can't really figure out what was the problem, since I've used
power mode ON for months and everything was fine.

Hope that helps someone else...

My experience with this error message is that it really depends on the received signal(s) and possibly having several network with the same SSID and the channel in use.

I have indeed 3 Wifi access points in my house. All are configured with the same password and encryption: WPA2 (AES). They also all have the same SSID and same channel. My purpose is to get a very good signal anywhere without having to take care of picking the best network myself (This is actually just a best practice).

But at some locations in my house, where I get either a poor signal or two signals of quite the same strength, I get the infamous "Authentication Error Occurred" message with my Galaxy SII (Android 4.1.2). I get this message whatever access point I am trying to connect from those locations (if several accessible).

First, it's important to notice that at the very same locations, my Sony Vaio laptop can connect without any issue. Reason why I also conclude it's an Android/S3 issue and not a router/access point issue. I can also at the very same time connect using my tablet with Android 4.0.4 (a Nabi 2).

Next, moving away from those locations (only a few meters), I can successfully connect quite immediately (I simply have to disable and re-enable the Wifi on my Galaxy SII). But in such cases, although I moved from only a few meters, I am now at a location where I get one signal much stronger than the others.

My access points are "DEVOLO DLAN 200 Wireless N". They only support WPA(TKIP) or WPA2(AES). So I tried to reconfigure them to use WPA(TKIP), as suggested here, but it didn't solve the issue.

I also tried to use shorter password (min is 8 chars) without success. But I admit I didn't try to connect using WPS (which is supported by my DEVELO).

I also tried to completely disabled the encryption for testing purpose, but as I am not mad I did enable the MAC filtering (which I don't use usually). In that mode, the connections succeed really more often, but not always. I still get from time to time the message mentioned above. And there is at least one location where I can never connect with my Galaxy SII although I can with my laptop: my bed

During my tests, I am monitoring the wireless signals using "Wifi Analyzer", to be sure that the signal keeps "stable". So, this is not presumed to be the issue either. And anyway, I do the same test simultaneously (I.e.: I enable the Wifi and wait for a connection) with my Galaxy SII Android 4.1.2 and my Nabi 2 Android 4.0.4. At some locations, only the Nabi 2 get the connection. But if I disable the Wifi, move from a few meters and re-enable it on both devices, then, I get the connection also on the Galaxy. When located on my bed, I can repeat the test 10 times with the very same outcomes.

Did I finally solve this issue... Maybe... I have switched from channel 6 to channel 13 on all my access points and I can now connect flawlessly from all the locations where I was experiencing issues. That being said, there are possibly some other locations where I will experience the problem. But for sure, changing the frequency has an impact on the reception!

As far as choosing the right channel is concerned, here in Europe, it's well known that frequency 2450 GHz is the one used by microwave ovens. So, those could possibly disturb the Wifi channel 9 and 10. But if your does, change it immediately ! Radiation that escapes from a microwave oven while it is in use may not exceed 5 mW (per cm2 at a distance of 5 cm). So, if your experience Wifi issues when using your oven, the leakage radiation is probably exceeding that limit. It happens as some of my colleagues have already experienced.

Next, I just discovered that frequency from 2400 to 2450 MHz (channel 1 to 8) are used by "ham radio" who are therefore maybe impacting the use of our Wifi (especially as they go up to 120 watts while Wifi is usually around ~18-30 mWatts). Check within your neighborhood if anyone has such a hobby. This could likely be the case if you experience issues only during certain period of the day (e.G.: the evening) or during the weekend.

Channels 1, 5, 9 and 13 are known to be used by some wireless transmitter and camera (at least here in Europe). As I don't have such device, and taking into account this info about the frequency used by "ham radio", I decided to use 9 or 13.


O.

I am also experiencing the wifi authentication error on my samsung note 2. Have tried numerous fixes including various different roms and apps with no success. I have tried several different wifi routers and always the same results (including having the wifi open with no password, will still give me authenication error), BUT as long as I'm within 5 feet of the router it'll work (as soon as I move farther away and try and re-connect I get the authenication error). All other devices connecting (my IP cameras, laptop, wife & sons cells) to same routers are not having any issues. Any help would be much appreciated.

thanks

POSSIBLE FIX:I got the galaxy 3 tablet yesterday, it connected to Wi-Fi no problem then today I got the authentication error, tried reboot, forget network, reconnect, etc with no luck. My password was correct and I have a the galaxy 3 phone which connects with no issues as well as all other devices. So, I went into the modem settings and changed my security type from WPA-WPA2-personal to WPA-personal and PROBLEM FIXED.

It appears this thread is at its conclusion or nearly there (hope not!). Has anyone found a working solution? WiFi access on ALL frequencies on my 1 year old SGH-I317 was flawless until I recently had to factory reset (for other reasons) my SGH-I317 running on Android 4.3 and now I cannot connect to anything using 5GHz in the WiFi spectrum. I have tried different WiFi devices at home (3 of them) and at my workplace (1 of many) and the phone keeps reporting the dreaded "Authorization error occurred". The 2.4GHz freq appears to work fine to all those WiFi devices, and the phone connects quickly and without issue at that freq. All the home WiFi routers work fine with other 5GHz clients such as my HP laptop, my wife's iPhone 5 and my son's Samsung Galaxy S4, so I am not about to run out and buy new WiFi devices or do factory resets on these routers. The 4GLTE with AT&T is also not affected.

I was not sure if there was an application that I may have installed that was causing the problem after the factory reset, so I did the factory reset again and before loading any additional apps, I tries to connect at 5GHz and still the same error.

I have tried the obvious forget network, stop and start WiFi and connect again fix (no joy), the "*#0011#" fix (interesting, but no joy) and several other remedies but with no success.

Is this a JellyBean/Android issue, a security protocol (AES) problem or what?

Thanks for any help

I've had the same problem with my phone (galaxy s3) since the last update. I've gone through all of the troubleshooting suggestions as far is rebooting and resetting hardware, with no solutions. I found that by changing the name of my network, my phone was able to connect to my wifi.

I am having some problem with my s3. I'm not able to connect my s3 with my wifi . it saying incoorect password but my router have no security it's open please help me .

If you have an Android, go to settings, then click on Wi-fi, scroll all the way to the bottom to where it has +Add Wi-fi Network. Manually input the SSID and password. It's what I had to do. I have a Netgear 10 as well and was alright when I connected to it the first time. Then we changed the password on the Netgear and phone refused to connect. So try this. So far, I'm still connected and not running down my battery. ^_^

Thank you very much!!! Your solution worked for me, tonight!

I found the person who sent the message that helped me. He is "wvuguy". He sent the message on April 19, 2013. I should have read these messages a long time ago. But it helped me last night, anyway. I hope it helps you.

I think I may have some info to help figure a solution to this problem. I have noticed that my G2 especially loves doing this, but my Note and S3 have also had the exact same issue. Just a little background on my setup, I too have a dual band router and I utilize the DHCP reservations list. When I connect to the router on the 2.4Ghz network and create a reservation IP address, then reconnect to the 5Ghz one, my MAC addresses will change on the stations listing. This option shows the real time connections to the router. Many times this will also flip between wireless N and G bands as well, even though my devices and router are only setup for wireless N mode.

I have not found a good workaround yet, even when attempting to add both MAC addresses into my reservations list. It will only connect under the first IP/MAC reservation. I am not sure why it comes up like this, but I thought maybe the input would help. I too would love to fix this odd error. This cap should be worked out already.
