Hi!
To be able to connect with real devices you need a wireless adapter, do you have one?
You will need it as well to get a connection from devices outside the network, for this you need to set port forwarding rules in your router and use your public ip in the backdoor.

And as long as the devices are connected to the same router then it doesn’t matter if it’s a wired or wireless connection, the network is the same.

Greetings!
