Choosing the Right Network Cable

When connecting your computer to the network, you must use a network cable (also known as an Ethernet or CAT–5/CAT-5e/CAT–6 cable). A regular phone cable will not work, even though it looks similar to a network cable.

Network cables can be purchased at the OSU Beaver Store.
