Sorry if you know most of this but just incase you don't. Bring up your full settings page and make sure wifi is turned on then tap on the word Wifi so that it shows all available networks. Assuming your network is showing just tap on it and it should bring up a box with the options to Connect Cancel or Forget. Tap Forget and it will delete any password you put in. Refresh the list of networks and then select yours and re -enter the password. Select to show the password as you tap it in so that you're sure it's absolutely correct. That's about as far as my advice on networking goes so good luck.
