Nigthawk X4S Ac2600 can not connect to ISP

[JH02]

I have just moved to a new ISP provider (I am in Australia)

They have provided their own modem router - which connects - no problem.

However I can not get my Nighthawk X4S to connect to the internet.

Are there some settings I need to change ?

Hoping someone can help

Is that a D7800?

That is a DSL modem. Is the new ISP using DSL or something else?

From questions here, Australia seems to be big on NBN.

What is an NBN network and is my NETGEAR DSL modem router compatible? | Answer | NETGEAR Support

You might be able to have your router use your computers MAC address and get it to work.

Have you connected the computer directly and got internet service?  If you have then do the following.  Log into the router.  Under the Basic tab select Internet.  Scroll down to the section that says Router MAC Address.  Select Use Computer MAC Address.  Click on Apply at the top of the page.  Test it out.
