I have 2 X new Samsung Galaxy S3 phones and both are doing the same thing. That is they are NOT connecting to my WI-FI router if I have security enabled. My laptop connects to my router just fine.
I'm using WPA-PSK authentication with TKIP encryption. (Aslo tried AES with same results)
I've tried a different channel with same result. I typed the passphrase 1000 times already and sure I typed it correctly. Even changed it on my router to something more simple and still nothing.
I've added both phones MAC addresses in the mac address filter and set it to "allow". Same as my laptop which like I say works just fine.
The S3 just keep on saying "Authentication Error". So if i switch from WPA-PSK to just no security (no authentication) then it works fine.
Arrrg so frustrating. I found a "trick" by googling and the *#0011# trick doesnt work by switching off the WI-FI pwer saving. Still same results.
I even upgraded my router firmware to the latest and still same result. Can't see how both phones will have same problem.
I'm running Android 4.04
The router is a Telkom 5102g (Billion inside)
At a different site it also connects fine to the wireless although here it also has no authentication so not really a troubleshooting test. At the 2nd site I dont have access to modify the router. Only at home.
(my router doesnt have WPA2 and there's no way I'm switching to WEP)
