Hey all, need a little help setting up. I've moved into a new house that has 2 AP unifi 6 in the ceiling that I'm not sure how to work, in the garage I have the NBN wifi with the modem setup with two injectors above I have a Ethernet port labelled D1 and then on the other side another 6 ports D2 to D7.

I'm not sure how to set them up as it's a house I've moved into. Anyone able to help?.
