I want to install Home Assistant, LAN is not available. Is it possible to use Wifi for installing?
Kind regards
The best way to get HA communicate over a wireless network is using a wireless bridge. This way you can still use the RJ45 port on the HA host, and therefore bypass NIC driver issues, but still use WiFi as the underlying communication method.

There are plenty of solutions out there for all budget levels, even on Amazon (search: WiFi bridge). I suggest you opt for a WiFi5 or WiFi6 bridge. Minimum you should opt for is WiFi4 (802.11n).
Good luck.
