Here's a less analytical way that may work if you have marginal signal strength: 1) Connect wirelessly 2) Start pinging a site near you (to mimimize delay effects over the larger internet) 3) Move the antenna around to see where ping delays minimize across Similarly, you can do the same thing with traceroute which is even better because it shows delay at each step of the route. This is a quick-and-dirty scheme that may not always provide best results, but it's easy and a good way to get started....
