Wired Internet in DRL

  • Faculty & Staff

Using the wired network in DRL requires that you register your computer's MAC address.

Use the instructions below to find your computer's MAC address. Then, using a computer already connected, go to the DHCP Registration website and register the address using your PennKey and password.

Depending on location, it may take up to 20 minutes for servers to update. Usually, the wait is much shorter.


Your MAC address should look something like this: 00:55:AB:55:CD:00

Windows 7 / Vista / XP / 2000
