Hap ac2 setup basics

Hi there,

I am totally new to routing and setting up something more than simply plugging in my internet connection to the router lol.

What I am trying to achieve is to connect a Hap AC2 to my existing D-Link 825 router’s wireless (SSID: wifi1) and then from the Hap AC2 via ethernet to a server.

basically:

INTERNET → D-link → SSID:wifi1 → hap AC2 → Ethernet → Server

With the setup above I would like to have a device (laptop) on SSID:wifi1 be able to ssh into the server (shown at the end of the chain above).

I am so new to this that I don’t know what to even search for.

Please could someone point me in the right direction?

Thanks in advance.
