Cannot reset

My old extender has worked fine, but upgraded my widi to Frontier with ARRIS router.  I have tried several avenues to connect this extender but seems I cannot reset. Have held the paper clip in hole for over a minute. 

I can get connected but no Internet connection.

I am somewhat confused as my new router has all other devices running with WPA2/AES security.  Shourd my extender continue to use WEP.

I have held down the WEP button extender and pushed the button on front of router as instructed.

So basically I am lost. 

Does this extender just use WEP or can it use the WPA2?

How can I reset the extender and start all over if paper clip is not doing a reset?

Thanks. Bob
