Can't Continue N300 Setup after Naming Screen

Hi everyone,

I'm having trouble setting-up my extender using a Macbook. It runs me through the first couple of screens with no issues and even finds my router and lets me select it however, once I reach the screen that allows me to rename the extender and select a security type it does not respond to me clicking the "continue" button unless I select "none" as the security type. Obviously, I want the extender to be password protected and have the same requirements as the router. How do I remedy this situation? Thank you in advance. Please feel free to let me know if I need to elaborate more.
