I have bought a switch for my modem to allow me to connect my PC on windows 10 and my apple airport extreme that way i could use both but upon plugging it into my PC is says unidentified network through the Ethernet cable and it will not let me use it. so i have had to continue to plug my Ethernet cord into my airport instead of the switch. would there be any way to fix or use Ethernet directly through my modem and not my airport
