Try the wireless network
All of the MIT residence halls have complete 802.11b/g wireless coverage in addition to the wired ethernet network. There are two ways to connect your computer to the network and internet at MIT. While the traditional wired network is useful for some desktop computers and server setups, Residential Computing at MIT asks that dorm residents with laptops try connecting to the wireless network for everyday computer use.
Get an ethernet cable
If the wireless network does not meet your needs and you would like to use the wired network connection, ethernet cables are available free of charge from IS&T. You can pick one up in Building E17 between 9AM-5PM. You can also get ethernet cables from your dorm's Residential Computing Consultant (RCC).
