My SG III s wont connect to ATT Uverse router. Ive gone through ATT help and they say its the phone. Ive gone through Sprint (phone & service provider) they say nothing is wrong with the phone. Samsung support also says nothing wrong with the phone.
It connects to unsecured networks no problem. If i turn security "off" in my uverse router it connects no problem.
With security "on" in my uverse router i get an "authentication error occurred" on the phone. Even though the status bar on the phone shows it sees my router at excellent strength.
And yes I have verified the password with correct upper and lower case.
Ive connected to several unsecured WiFi without issue.
The only secured network I have connected to is at work. I know they dont have uverse but, have no idea what the WiFi brand is. It connects no problem with security on and my office password.
Phone is running android 4.0.4
Ive changed router settings to use channel 11 and power level 400.
Ive rebooted router. Reset the phone.
I can also see in the router the MAC address for the phone. So I know they are seeing each other.
