Hi,
Have a new Netcomm 18Mesh as primary router into the NBN modem but want to extend the WiFi range.

The NBN comes into the house in the far corner of the front room and that's also where the 18MESH is.
I need to a good WiFi signal out of this room to the rest of the house.
I also have a Netcomm NF17ACV as well as two TP-LINK AC-1300 Deco M5 Extenders.
Is it best I cable the NF17 to outside that room, then run the Deco's as Wi Fi from that?
Or is there a better way?
Also what are the basic settings in the NF17 to set it up as an AP?
Thanks
