btw it seems simpler to plug a wire from the unmanaged switch to the wifi router assuming it also has an ethernet port. they usually do. no idea what address the wifi router would use but you can look it up.
Maybe set up the scope on the router so it's DHCP up to 192.168.0.1 - 50 say and then set static IPs on the ESXI hosts to 192.168.0.51 and then ESXi host 2 to 192.168.0.52!
