Is there software that one can install that can tell you which way to move your laptop to get closer to a wifi hot spot or any other available wifi signal? I use to have something like this five years ago or so, but I do not know what the software was because a friend installed it for me.
There's a program called Easy Wifi Radar (http://www.makayama.com/easywifiradar.html) that may be what you're looking for.
Netstumbler is better for analising... To discovering networks, software form producer of your wifi card should be enough.
Quick question. Is there any version of "Wifi Radar" that you know of for Vista? That would be an awesome tool to have, considering I reside on campus at a University where wifi signals and routers are hidden in the ceilings ... some places have better signal than others.
