Very good Project for our new experiment Puntuado con 4 de 5 estrellas
Actually we are also working on this kind of project. and you've made a good combination of codings.

This could be a really handy add-on, but unfortunately, without the ability to copy & past the info it generates, its usefulness is *VERY* limited ;^<
dBm / logarithms / OMG Puntuado con 4 de 5 estrellas
In the "WiFi Finder" Add-on, the column with the signal-strengths is labeled "Signal." The units are dBm.
A higher number is a stronger signal? A lower number is stronger signal? dBm / logarithms / OMG
I like this explanation better:
Background -- refresher of elementary arithmetic; we're talking about "The Number Line." I wish I could include a graphic of a ruler that goes from -80 to +20; 0 is in the middle, somewhere; and of course actual numbers go below -80 and above +20. For example, two ways of saying the same thing:
20 is a higher number than 10. (20 is more positive than 10.) 10 is a higher number than 0. (10 is more positive than 0.) 0 is a higher number -10. (0 is more positive than -10.) -10 is a higher number than -20. (-10 is more positive than -20.) -20 is a higher number than -80. (-20 is more positive than -80.)
The signal strengths in dBm follow the number line. Harmoniously, the stronger the signal strength, the higher the number in dBm, and/or, the "more positive" the dBm value.
For instance, a signal that's -60 dBm is stronger than a signal that's -80 dBm, because -60 is a higher number than -80. Or if you like the other nomenclature, -60dBm is a stronger signal than -80 dBm, because -60 is "more positive" than -80.
As a signal gets stronger and stronger, its dBm value may cross over "0" and become positive. However, even when I physically touch my USB WiFi adapter to my router, I cannot get a level higher than about -20. I have never seen a WiFi signal with a positive dBm value -- they are not needed to provide coverage around the house.
In summary, that means we're stuck with dBm values that are normally "negative," which can cause confusion to break out. But I hope it becomes 2nd nature that a stronger signal has a higher value, i.e., a more positive number -- which is intuitive, right? And the WiFi Finder add-on displays the numbers correctly, with all of their minus signs.
Where do the logarithms come in? I don't think it's important to analyze that, unless you want to take up Math as a hobby. All that's necessary to "use the tool" is to properly interpret which is the "higher number," and know that's the "stronger signal."
I give 4 stars to WiFi Finder because I'd also like to see which channel the different signals are on. I would be concerned if the neighbor's signal is as strong (or stronger) than my router's signal. But if we are on different channels, then it wouldn't be a concern anymore.
Keeping it (but disabled until...) Puntuado con 3 de 5 estrellas
Could be handy as quick way for grabbing MAC's but I'll be keeping it disabled until I need to do that....for whatever reason that may be!

Meh, not great, not horrible. Puntuado con 3 de 5 estrellas
My mac shows 22 WAP listed and this doo-da shows at most 19. So it's not horrible but definitely wouldn't be reliable. I'm uninstalling it.Esta valoración es de una versión anterior del complemento (1.411.33.1-signed.1-signed).
IT DOES NOT WORK!!!! Puntuado con 1 de 5 estrellas
I'm using windows 7 and Firefox v18 and nothing happens when I click the icon. It's useless!!!Esta valoración es de una versión anterior del complemento (1.411.33.1-signed.1-signed).
The instructions say that "Signal strength is in dBm so the lower the better it is". My experience is that the best signal strength seems to be from networks with a higher value. Am I misinterpreting?
