You will need to reconnect to the new Wi-Fi network after changing the Control Hub's name and/or password.
If you are unable to connect to the Control Hub's network after switching to the 5 GHz band,
you can perform a Wi-Fi factory reset by holding down the Control Hub's button while you
turn it on, until you see a rapid sequence of color changes on the Control Hub's light.
The Wi-Fi network name and password will be reset to their default values, and the Wi-Fi band will be set to 2.4 GHz.
