    I’m about 62% sure this is a joke…

    Please help, I’m clueless about this kind of stuff.

      Look up the DIY parabolic reflectors people used to use on their WiFi antennas, they did actually work! I used one and recorded a marked improvement in WiFi strength at the furthest point in my home that was previously a low connection quality spot.

      Radio waves come out of an antenna and just go in every direction, so a router against your outer wall is wasting a lot of its energy just directed into the neighbour’s house. If you can reflect some of that back in, you get improved signal reception. It’s very cool :-)

      It’s the same principle of al satellite dish and it works, but I’m 86% sure that mirrors won’t affect wifi, so we’re still not at 100% but getting there.

        Depends on what frequency your “mirror” mirrors.

        A traditional one reflects higher frequency of electromagnetic rays (visible light) than what you need for wifi (in the microwave frequencies)
