Ethernet to ground unit

I can´t connect to the ground unit via Ethernet. Everything works fine with Wifi.
But I would like to skip the wifi hotspot, and use wired connection to our GCS, QGC.
How is this supposed to work? Does the ground unit have an DHCP server? Or should it be connected through a switch?

Yes, you can enable/disable the Ethernet hotspot as well as the WiFi hotspot in the main settings file. Ethernet is disabled by default.
