Ethernet is the proper name for wired computer network technology, as opposed to wireless or WiFi computer network connectivity. Ethernet is a great alternative to wireless connectivity for folks that are experiencing wireless network troubles, and many computers have an ethernet adapter built-in.
There should be one Ethernet port (TSO - telecommunications service outlet) active in each room of student residences on campus, although you may find more than one port in your room. There may be a small white plastic appliance with Cisco brand on the wall as well, and this appliance will have 3 or 4 ethernet ports in the bottom that are the best place to plug in. Please note that the diagnostic LEDs on these appliances have been configured to stay off to prevent sleep disturbances at night.
Ethernet adapters are small devices that connect your computer or computing device to the wired network via your computer's USB port. These adapters will have their own unique MAC address and will need to be registered prior to providing network access, similar to registering any other device on campus. They are widely available online and at local electronics retailers for $20 or less. Don't forget the Cat5e Ethernet cable as well!
