    Does any 1 knows how to solve problem that my Samsung Galaxy S4 have? I couldn't connect to the WiFi. My home WiFi can be connect just that i can't connect to my office WiFi and public WiFi. Password is correct but still couldn't connect to it. Always trying to connect but pop up message, authentication error, My boss using S4 as well but she can connect. I updated my firmware from Kies3, since i updated the firmware, its started have this issue.

    Are you using a custom Rom? Sometimes a Rom doesn't play well with all the features of a device. Mine currently doesn't connect; but there are modules you can flash through a custom recovery that still fix all permissions, coding, buildprops, etc. I believe they're on XDA. Just use your firmware version (probably 4.3...MK2 if you've just upgraded using Kies) to search ex. MK2 Wi-Fi modules.
