Hello, i want to make an box to keep my wifi router in at my airbnb, so that guests can't tamper with it. the box will be made from wood on the corners and punched metal sheet for the sides (like in the pic bellow)

Assuming that my router is the kind with external antennae and i modify the box to have the antennae on the outside of the metal sheets, am i right to think that i will have no issues with heating and signal reduction ?

Thanks!

Yes it will significantly reduce the signal. The wavelegth of WIFI is 120mm, and a holesize smaller than half the wavelength reduces the signal exponentially. So a mesh with holes smaller than 60 mm (2,4 inches) will significantly impact it. .
