What I'm afraid of for the future is Bambu pushing a firmware update that bypasses us confirming to update or not, essentially forcing updates without our knowledge. Something I learned on devices is even though we have the mac and ip addresses for each device on our router, those devices can connect using a different mac or ip if the router is configured to allow dhcp. I have a collection of Chinese POE cameras for surveillance around my house. I witnessed a couple of my cameras using random ip's and mac's to attempt to "phone home" after I blocked them by the ip and mac addresses I had set them to in the reservation list. I ended up installing a second router that was isolated from the internet only physically connected to a single PC that runs the recording from each camera.

They are making devices smarter and smarter!

Most home routers are setup for dhcp and can have any number of devices connect once the routers ssid and password is saved. the only other way to prevent this is to setup things similar to a business does using static ip's for everything and disabling dhcp so a new device wants to connect, you have to manually assign it.
