I have a Losmandy mount which has a lan connection for control (RJ45) so for star parties I have :-
Gl.net mini router (3 lan ports and USB C power) - connections of lan-mount, USBC-C charge port to NUC USB charge port for router power. - or maybe this one https://www.gl-inet.com/products/gl-mt1300/
Intel NUC for all my imaging and control software - connections of lan-router, USB charge port to Router, USB to Pegasus power/USB box that supports all the cameras, focuser, EFW, etc... Substitute Mele for NUC in your case.
The Gl.net acts as the wifi access point, the lan hub and the DHCP server for all the devices (mainly with fixed IP addresses for the NUC/Mount but DHCP for all the clients to the wifi). I set up 2.4ghz and 5ghz SSIDs as 2.4ghz is better for longer distance wifi usage (use either based on situation)
