EX6100 extender not accepting password

I'm still at the initial stage of setting up using WPS. All the lights are working correctly and the new network is visible but the password for my original router is not being accepted. It is the correct password because it's printed on the router.

I've seen a few posts for not accepting passwords but they all say to adjust settings in the netgear genie. 

How do you get that up and running without putting in the password first? 

The genie won't connect unless you're using the new extender connection!
