"All this and it's free?!"
Provides great visual insight into the strength over time of all the wifi signals within reach of your PC. Filter by strength gets rid of the nuisance signals. Click on signal of interest "bolds" that signal; so it's easier to pick out of the mix.
If there's a way to assign colors manually I didn't find it, but it's so intuitive that reading the documentation is optional.
I ran this on five different XP machines and inSSIDer performed perfectly in every instance as far as I can tell. Surprising variability from one machine to the next in terms of the signals detected and the strengths thereof, but results were consistent with the Windows and/or 3rd party wireless apps on those machines so I think the inSSIDer display had some basis in fact. Compared to the basic apps inSSIDer simply provided a time based view and much more signal strength sensitivity, exactly what I needed. And it looks REALLY cool! Thanks to the authors for a great piece of software!
