WiFi: Register Your Chromecast Device

Devices like the Google Chromecast are designed for home networks. Connecting them to a complex enterprise network requires more steps. This article outlines the Chromecast setup steps for U of M residence hall use.

Important: You will need the MAC address of your Chromecast device to complete the registration process. Newer models do not list the MAC on the box or device. To find the MAC address, you will need to run through a partial setup and then register the MAC before completing the setup process.

Registering your phone as an IoT device temporarily

For setup, your Chromecast and phone need to be on the same WiFi network. To do that, your phone needs to be temporarily registered as an IoT device.

Starting the Chromecast configuration process

  1. Download and install the Google Home app on your phone.
  2. Connect your phone to the UofM-IoT WiFi network.
    • Note: While connected to the UofM-IoT, you won't have access to many U of M services that require central authentication. Those services require your device to use the eduroam network. After completing this process, return your phone to eduroam.
  3. Connect your Chromecast to a display, and make sure it is on.
  4. Open the Google Home app.
