Using the wired network in most SAS buildings 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 website and register the address using your Pennkey ID and password.

* Depending on location, it may take a short while (up to 20 minutes) for servers to update. Usually, the wait is much shorter.
