setup of nighthawk ac1900 behind Att uverse router

[gbridgeman]

My router provided  by ATT has too many devices attached so I bought the Nighthawk since users said is can go behind the primary ATT router.

I cannot connect to the new router. There are no directions with the router so I'm stuck.

Thanks

A couple things.

1. you put nighthawk router but your signature lists the C7100v which is cable modem/router.

2. You put that you have att with a att router. running 2 routers on a network puts you in a double nat. You can get around this by placing the att in pass through/modem only or a regular router in AP (access point mode). But that option isn't availble if you have the C7100V.

So what actual router did you buy?

You can go to netgear.com/support/   type in your actual model number and it has install videos, install instructions, manuals, and firmware.
