  • Select Mobile Hotspot from the listing of network information and settings.
  • Enable the toggle switch under Share my internet connection with other devices.
    • Make sure the dropdown box under Share my internet connection from has the correct connection selected (e.g., Ethernet, Wi-Fi).
  • Select the Edit button.
    • Here you can edit the hotspot information.
      • Make any adjustments to the Network nameNetwork password you need.
      • Choose a Network band (2.4 GHz, 5 GHz, or Any).
        • Leaving the band set to the default of Any allows any of your devices to connect to your hotspot regardless of their band capability.
          • This can prevent future headaches of a device using only 2.4 GHz not connecting because you selected the 5 GHz Wi-Fi channel for your hotpsot.
  • Save your changes.
  • Make sure the toggle for Mobile Hotspot is On.

For a more advanced setup process, you can use the command prompt to configure your Wi-Fi network settings.
