Find Your MAC Address

Using UCInet Mobile Access requires registration of your hardware or MAC address. If you are using Manual Registration, you will need to locate the MAC address of your wireless device. Use the directions below to locate your MAC address.

What is a MAC address?

MAC (Media Access Control) address is the hardware address of the Network Interface Card (NIC) of your computer. You must have it on hand to register for the UCInet Mobile Access network and campus-wide DHCP services. This Web page will help you locate and identify it so you may register your Network Interface Card (or cards) for the network.
