There is a wi-fi router emitting radio waves (wi-fi) in a room. The room has solid walls but also a thin anti-mosquito net door and that net is made of metal (I think, but I'm not sure).
When I am outside of the room, the wi-fi isn't working so well but when I am outside and open the door it is working better, so can that mosquito net (if made of metal strings) act as a Faraday cage and perhaps absorb or block the wi-fi signal?
