Make a Wi-Fi Extender

Make a Wi-Fi Extender

It is a cheap and relatively easy way to boost a wireless routers signal strength by creating a simple parabolic reflector dish to direct Wi-Fi signals to your intended receivers.
Print out the template on a sheet of regular paper. You can actually scale the image to a larger size while maintaining the relative dimensions for a stronger focus. First, cut out the template pieces, then use a glue stick to affix foil to the front of each piece. Use a knife to make cuts on the indicated slits and bend the reflector to fit the six tabs into the respective holes.
Slide the booster over the existing antenna of your router and point it in the desired direction.
