Enclosing a router with aluminum foil will provide minimal shielding against radio frequency (RF) signals. While aluminum foil can block some RF emissions, it is not as effective as a properly designed shielded enclosure with RF filtering for power inputs. Users experimenting with this method should note that the results will not replicate the performance of a dedicated shielded box. Overall, this experiment highlights the limitations of using simple materials for RF shielding.
PREREQUISITESElectronics enthusiasts, RF engineers, and anyone interested in experimenting with wireless signal behavior and shielding techniques.
If you put the router into a good quality shielded box with RF filtering on the power going into the box, very little of the RF signal will get out of the box (or into it from outside). Wrapping aluminum foil around the router will have some shielding effect, but nowhere near what a good shielded enclosure with filtered power will have.kos said:
