Will a Faraday cage block WIFI?

Faraday, an English scientist, built what is now known as the Faraday cage, an enclosed space constructed out of conductive material that blocks electromagnetic signals from entering or exiting. … Inside this cage, those Wi-Fi and cellular signals would be rendered totally useless.

How do you test a Faraday cage?

A good method of testing is to place a portable battery-powered receiver, tuned to a station with continuous program activity, inside the enclosure and close the lid. If the signal drops to the point that only static is heard emanating from within, the enclosure will likely work well as a Faraday cage.
