My router / modem- how do I hide, lock, and protect it?

[Matt Miller]

For my vacation rental, I'm not sure where I should put my modem / router to protect it from guests.  I don't want someone to steal it (cost me $200), or press the buttons on it.  

I was thinking of locking it inside a cabinet, but that would probably interfere with the wifi signal.  

Another idea I had was to put it into a "rack cabinet enclosure" (Amazon) and then somehow bolt that down onto a shelf or cabinet.

But then the router/modem would be visible... I'd prefer to put the router someplace that completely hides it, yet doesn't interfere with the wifi signal.

Same problem with my Ring security system.  It connects to the router through the ethernet port-- I want that to be visually hidden as well.

Any ideas here ???
