Boosting a WiFi signal can be an expensive proposition, requiring the purchase of either a second wireless router, or a wireless signal booster. Unless, of course, you build one yourself. From Instructables:
The parabolic Asian cooking (dumpling) strainer is the perfect candidate for this project. I was able to pick up 20 more access points in the city and connect to a network a few blocks away! This is BY-FAR the most simple of all Wifi extensions!
To build the booster, you need a USB extension cable, any USB WiFi adapter, and a tight-mesh parabolic cooking strainer. To reach WiFi signal heaven, stick the USB WiFi adaptor through the center of the parabolic strainer and connect it to the USB extension cable.
