Nick sent in this great build for improving your WiFi connection. There are a lot of different ways to make WiFi antennas, many of them featured on the MAKE blog. This is a nice design based on the Yagi antenna, which has been around since the 1920's.
I have been playing around with some wifi networking lately, mostly with the La Fonera, and finally decided to build a directional wifi antenna. Although the cantenna, however, I don't really like Pringles chips and wanted to make something more interesting. I decided to try and make a simple Yagi antenna with a magnetic dipole as the driving element.

Good job on that Yagi antenna! For more long range antennas, havea look at my construction guides at:

For popular USB wireless adapters there are also external antenna mods that work great. You can get much better performance with simple mods (generally no need for amplifiers).
