WiFi was the killer technology that made home networking easy. No more messing around with hubs and cables and drilling holes in walls, simply turn the devices on and hit connect. Over time the speed and range has increased, but those with larger houses or granny flats out back have suffered. There are tricks to boost range however, and some of them involve cookware.
The clever hack here is to use a metal strainer as a parabolic reflector, to capture signals and focus them onto the PCB antenna in a USB WiFi dongle. The strainer is drilled out, and a USB extension cable has its female end glued into the base. This allows the dongle to be positioned inside the strainer. For best results, the dongle should be positioned so that its antenna elements are sitting at the focal point of the parabola; this can be determined through mathematics or simply by experimenting with positions to see what gives the best signal strength.
It’s a design that is quite directional, and should help boost signals as well as block out those from unwanted stations. The build is simple, and can even be tripod mounted which helps with aiming and looks cool to boot.
For many, WiFi antenna hacks are old school, but it’s always good to keep the techniques in mind as you never know when it will come in handy to solve a new problem. Some crazy things are possible with the right gear, too.
