If you only have the hog connected - and no other artnet devices, ensure that the hog has an artnet address in the same range: 2.0.0.x and try setting the subnet mask on the artnet adaptor to 255.255.255.0

Is the additional network DHCP assigned?
It seems that this takes precedence, even when network service order if set to artnet adaptor. Try making it a static address if appropriate.

Are you sure that theres nothing connected to the 'additional network' that may be generating artnet?
