When I got a new Apple TV, I decided to plug it directly into my Time Capsule via Ethernet to lighten some of the bandwidth load on my home wireless network. My Wi-Fi bandwidth has always been pretty lackluster with my first-gen Time Capsule, even though every device connecting to it is 802.11n-compatible, and adding something as bandwidth-gluttonous as an Apple TV streaming 1080p video from my Mac was only going to make things worse. I guessed that plugging in via Ethernet would roughly halve the bandwidth requirements
