How do I get my iPhone to connect to my Wi-Fi?

I have tried resetting my iPhone, resetting network settings, reset all settings, updating my iPhone, updating iTunes, syncing my iPhone yet every time I put my network password in it says it's incorrect? Also the Wi-Fi connects just fine on my mac and other phones.

Take it to the Apple Store, or try connecting it to somewhere with public Wi-Fi, if that works then there's something wrong with either the password your putting in or you Wi-Fi connection at home
