Overview

So they suggest doing troubleshooting procedures on both the wireless network and the phone.
This problem was experienced by other users with different devices during Gingerbread times. The sheer number of Galaxy S3 owners who reported to have experienced this problem made it like it was an S3-exclusive issue even though it’s not. So this tutorial, while we focus more on helping Galaxy S3 owners, could also be used for other devices like the Nexus 4, Galaxy Note, etc.
Signs of WiFi Authentication Error
Aside from the error window that would pop up, the following are signs and symptoms that you are experiencing the WiFi Authentication Error.
- WiFi refuses to connect without apparent reason.
- The connection randomly drops.
- WiFi connects but immediately disconnects after acquiring an IP address.
Possible Fixes
There’s no point in trying various troubleshooting procedures if you don’t know what the problem is. So, the first thing you’ll have to do is isolate the issues so you’ll know where to begin.
- After getting the authentication error in your Galaxy S3, try to connect other devices to your network. If you have a laptop or other mobile phones, try connecting them to see if they, too, would get the same error. If they can connect just fine, then you already know the problem is not with your router/network.
- Try rebooting your phone first. Reboot often fixes simple problems so you should try that before you go any further. Once the phone is up, try reconnecting to see if you can.
- Go to Settings => Wi-Fi and make sure the toggle switch is on. Tap and hold on the name of your network to open its settings page. Once it pops up, tap on “Forget this Network” button.
- Let the phone detect networks in range and select the one you usually connect to. Enter credentials and try to browse the web to see if you can.
- If you can’t connect to your network still, try to find networks you can temporarily connect to and see your phone works just fine. If it does, then try using a different encryption type in your network. There were reports that S3 not connecting to a network that uses WPA2. However, if your phone won’t connect even with other networks, there could be some problem with the software. Try to see if there are available updates.

i have the same problem with my s3 and i don’t know what to do with it now. It would connect to the wifi only if im a few steps. Please tell me what you did to fix your wifi module. I just really need to try it.
This article was zero help! It’s obvious it’s the software for which the article recites the obvious “However, if your phone won’t connect even with other networks, there could be some problem with the software. Try to see if there are available updates.” Wow! Brilliant! What if there are no available updates? What should I do then, “consult my network administrator”? I receive Samsung updates almost every week and nothing has solved this problem. Maybe this article should have been titled: “How To Fix Galaxy S3 WiFi Authentication Error For Dummies Dumber Than Dummies”!

Hello sir/madam,
I have SG3 and have been using since two years ago. It was working properly so far in all Wifi connection networs and in my room’s Wifi connection as well. Today, in the middle of the day, I realized it was not working and does not connect to Wife while my computer and my roommate’s phones are still working, the router is working well. It asks me to enter password and as I enter password, it says INCORRECT PASSWORD and then asks again to enter password. Later on, first “Saved, secured with WEB” and later “Authentication error occurred” appear right at the bottom of Wifi Network Name. I tried some other ways but did’nt work unfortunately:1(Dialling “*#*#0011# and turning OFF Wifi reset psm) and 2 (Changing IP address from DHCP to Static). Please help me and any suggestions. Thanks in advance for your suggestions.
My s3 would connect only when standing few feet away from the router.i tried everything mentioned by everyone nothing worked.just logged in to say it was a hardware fault which no one or no site mentions.the repair shop guy changed the wifi module.it connects like a gem now.
enter your Router settings >>wifi>>MAC Filter disable the Mac filter then all worked fine for me .. Good Luck
I had this problem JUST last night and it was so frustrating that I just slept it in and tried fixing it today. I tried all the solutions and almost give up, but then I tried the WPS process. go to SETTINGS>WIFI>LEFT BUTTON>WPS PUSH BUTTON, at the same time press the WPS button on your router. hope this helps. thanks!
I had this problem for the first time yesterday afternoon on my Galaxy Tab 3. Wouldn’t connect to the home wifi so I tried it on the hotspot on my Blackberry, same ‘incorrect password’ problem, so I knew it wasn’t my network, it was definitely the tablet’s problem. After trying several fixes with the router and nothing working a lightbulb finally came on over my head and I just turned the bloody tablet off and on again! Luckily this fixed it for me! But having Googled it just now to see what the actual issue is in case it happens again, I am horrified by the sheer number of people with the same issue. If it’s a known problem then why is there nothing in the handbook, no advice given on purchase, no bug fix update? I am not amused,anyway….
my galaxy s3 mini is not switch on the wifi connection and when i was connect with wifi modem it shows ‘authentication error’. Then the bluetooth is also can’t connect with other mobiles…
so please give me a solution for this problem..
I recently bought a Samsung Galaxy Tab3 10.1′ and was having problem connecting to my home wifi and was getting an authentication error while I could still connect to my wifi using my laptop and same password. After lots of trials/error where is the resolution –
Goto to your router home page and login (If you are not sure, ask your service provider example – Comcast in CA). Change the mode from 802.11 g/n to 802.11 b/g/n and then your tablet would have no issues in connecting. This is the one of the settings you have to do with Samsung Android devices. Hope you all find this useful.
Thanks.
