I've gotten me a Linksys 802.11b router so that I can connect my laptop which is primarily upstairs. Only problem is, I have a pretty weak signal which keeps going on and off. Instead of buying a Linksys Signal booster and a range extender (to repeat the signal in a location between the desktop and laptop), is it possible to make my own antenna, which i can point in a direction and boost the signal?
I've seen wardrivers using homemade antennas to amplify directional signal, so there is probably some solution. Any ideas?
