Download the manual from netgears website... also the user guide... they will have step by step procedures because you will have to reconfigure how you log into your wifi connection too on your computer. Needkarma provided you the link.

Go to your internet browser and type in routerlogin.net. Usually the default username is 'blank' and the password is admin. When your in click on wireless security and click on wpa2- personal. This way you can set whatever password you want as long as it is 6 digits or more.
