    So neat thing about WiFi, 2.4G Blows through drywall like it’s plastic window screen. 5G is dampened a little by it.

    Brickwork/masonry blocks 5G mostly, and 2.4G a lot, but not completely

    Most Low E glass blocks 2.4G a lot and 5G almost completely, so a glass wall is horrible for wifi, but if there’s just a window, it’ll easily go through the wall next to it.
