It's kind of weird setup issue. I'm using 4G router and it's far away from my home (~400m), together with a wifi broadcaster to cover my house with wifi.
So now I want to setup my C7 hub and noted it need a LAN point. (I wanted to replace my SmartThings hub that's connected to internet via WiFi, which is slow some time, reason to change to Hubitat).
Questions:
how do you setup LAN point out of wifi?
Does Hubitat able to connect to WiFi directly for setup purpose?
Ok so does this device not have a LAN connection? If not you can get WiFi devices that act like clients that convert WiFi to LAN. You would then connect this to a network switch which would give you X LAN points to use.
Use a WiFi Extender to receive the WiFi signal and convert it to wired Ethernet for connecting to your HE.
Plenty of extenders like this, such as TP-LINK AC750 Wireless Range Extender
Or try one of these, as suggested above by @Mr.Olsen :

Yep, bringing a WiFi signal fast and lossless over the distance of 400m, maybe through walls and other obstacles, will be quite a challange.
Assuming your rouer has at least one LAN port, the devices mentioned by @672southmain may be the most reliable and also affordable solution.
