Unfortunately, AppleTVs do not support WPA Enterprise, which is the wireless network type we use. Therefore, they are unable to connect wirelessly. However, AppleTVs are able to connect via an Ethernet cable to the data port located in your residence hall room. You will need to locate the MAC address of your AppleTV and register it with our network before you are able to receive access.
Locate the device's MAC address. Open the main menu, select Settings > About. On this screen, you should be able to see the MAC address listed as "Ethernet Address" or "Hardware Address." A MAC address looks something like this: 09:5A:43:02:6A.
Once you have located the MAC Address, register it.
Plug in your Ethernet cable to your AppleTV and to the data port located in the wall in your residence hall room. Once successfully registered and plugged in, you should be able to connect to the internet.
