ArtNet, sACN settings

I have ONYX running on PC, The ethernet adapter is crossed out and the Wireless Connection i selected using Artnet & sACN, is this correct?

It might be. That will get your PC sending sACN and Artnet to your wireless router. How do you intend to connect your fixtures? Do they connect via sACN directly, or do they expect a DMX signal? Are you using a hardware controller?
