Hi @cornkiller36795,
Welcome to the Roku Community!
I appreciate your inquiry. A 2.4 GHz network can be used to access Roku Smart Home devices. Owing to its distance from the router, attempting to connect to a public network or hotel's Wi-Fi will result in an error.
You can test the mobile hotspot if the camera is already set up, but I cannot guarantee it will function.
Note: During the first setup phase, the mobile hotspot won't function.
Or tell us more about this so that we can further assist you.
Thanks,
Rey
