For installation purposes, you must plug in at least one NIC

assigned to WAN. Otherwise, we'll temporarily assign WAN to the

assign and configure the WAN interface according to your requirements

If you haven't plugged in any network cables yet,
now is the time to do so.
We'll keep trying until you do.
