Can I use my Nighthawk X4S AC2600 D7800 as a router only?

Hi all,

Does anyone know if I can set up my D7800 as a router only, so that I can use it like a repeater to spread my wifi further through my house?

I have another modem that came from my ISP, and so I want to use the D7800 as a repeater but am struggling to see in the manual if that is possible.

Can anyone please help, and if so, point me to either the correct section in the manul or a helpful link somewhere?

Many thanks.

router and repeater are 2 different things. 

The D7800 has a router and access point mode. But not a repeater mode.
