If 2 devices are connected to the routers switch ports it will behave like a real switch and only forward the message to the destination MAC.

I want the desktop to access the internet directly through an ethernet connection and then I want to wirelessly broadcast this signal to my other devices. Basically, ethernet goes into desktop - and something sticks out from one of its USB ports that broadcasts a Wifi signal to …

When my laptop, a Dell XPS 15 (9530), is connected to my WiFi network, a new network with the SSID "DIRECT-IE[laptop name]msSP", where "[laptop name]" is replaced with the name of the computer.
