I get an average WiFi signal in my room from my router situated in my family room, so I did a bit of research to see what I could to make it better. I had read about the various "can-tennas" that people have made out of Pringles and soup cans, but I needed something free, and that didnt require pig-tails and connectors. So after a bit of digging, I found this: http://www.freeantennas.com/projects/template/ Make two of these, slip them over the antennas on your router, and it will boost the signal in the direction they face, while decreasing it in the direction they dont-great for increasing the privacy of any given network. For kicks, I made a quick--and I mean quick--set of my own: They are no where near perfect parabolas, but they took me about 10 minutes to make and prove the idea works. My signal increased by 10%, and the link quality increased as well. I plan on making a higher quality pair soon, when I get the materials I want. Just posting this for those who might suffer from mediocre signal strengths like I do--enjoy!
