I have an AirPort Extreme, which I already set up to broadcast a Wi-Fi network. I also have digital TV set top box (without Wi-Fi antenna), but it's a networkable device, so I'd like to get it online (to get video's on demand, etc ...). However, this device only has an ethernet-port and there's no internet cable connection in the living room (where the set top box is located). So I was wondering if I could use my AirPort Express to connect to my Wi-Fi network and connect the set top box to the internet through an ethernet cable, running from my Airport Express to the set top box? If this configuration is possible, can someone please inform me how to install it? Thanks in advance!
