Finding Your Network Adapter Address

OSU Access Wireless portal has returned

The login page for the OSU Access wireless network has returned. Information about that can be found here.

OSU Access is an unsecured/unencrypted wireless network. OSU IT staff recommend you use the Eduroam or OSU Secure wireless networks.

Your computer's Network Adapter Address must be registered in order to receive network access. The Adapter Address is a unique number associated with your computer's network adapter. It is also called a Physical Address, Hardware Address, Ethernet ID or MAC on various systems
