Finding the MAC Address for Common Devices

Last modified 7/20/2026


 Your device's MAC address must be obtained from the device you wish to register on the ISU wired or wireless network.

Before You Begin

To connect your computer, game console, or smart TV to ISU's network, the device must be registered in the ResNet Device Registration Portal:

Each device must be registered using its unique MAC address.

MAC addresses may appear in one of the following formats:

  • XX:XX:XX:XX:XX:XX
  • XX-XX-XX-XX-XX-XX
  • XXXXXXXXXXXX

Enter the MAC address exactly as it appears on your device unless otherwise specified by the registration portal.

Important

Gaming consoles and smart TVs with Ethernet ports should be connected to the wired network using an Ethernet cable whenever possible. A wired connection typically provides lower latency, faster speeds, and better multiplayer compatibility. When registering a wired device, use the wired MAC address (LAN MAC) rather than the wireless MAC address.


If your device is not listed below, consult the manufacturer's documentation or support website.

Nintendo consoles do not include a built-in Ethernet port and require a USB Ethernet adapter for wired connectivity.

If you are using a USB Ethernet adapter, you must register the adapter's MAC address.

You can choose between the official Nintendo Wii USB LAN adapter and a third-party adapter. If you purchase an official Nintendo LAN adapter, it may automatically connect to ResNet when you plug it in. We recommend trying to connect your official Nintendo LAN adapter yourself to see if you can get a working connection. Be sure to switch your connection type to Wired under the Connection Settings menu. If you are unable to establish a working network connection or are using a third-party Ethernet adapter, you must determine the MAC address of the USB LAN adapter to register it in the Device Registration portal.
