Pepwave surf on the go as pass thru repeater

I have a wireless hard rive that I have all my movies on. It creates it’s own wifi network. No matter how I try and set it up it won’t pass thru the pepwave. If I connect directly to hard rive network I can all the movies once I connect to the pep wave I can’t see any? What am I doing wrong.
Thanks

Hello and Good Day jimf12345

So this hard drive creates it’s own WiFi? Is it handing out IP address through dhcp?
