Did anyone facing WIFI connection authentication fail issue?
My S3 having the authentication fail issue while connecting to my home wifi recently, event my router has no password.

1.)I have try change my router SSID Channel from Channel 1 until Channel 12 but the authetication issue still persist.

2.)I try connect my home wifi using my notebook and is working fine on my notebook(tested with 3 notebook & 2 units of Samsung S4). But when i connect to my office wifi is working on my samsung s3.

3.)I try factory reset on my home router and the problem still exist even through i did no set any password on my router. (other phone and notebook is no problem with the connection)

4.)I try hard reset my Samsung S3  then clear cache and update all neccessary updates using mobile data but the result is still the same!!!

5.)I try to switch off the WiFi Power Save Mode but the result is still the same!!!

6.)I try to wifi connection by flight mode but the result is still the same!!!

My phone is out of warranty, anyone know how to solve this problem?(My S3 is not root and is original kernel)
