It changes as regularly as the signal might, maybe adjust your computer to where the signal stronger instead of weaker more easily. Small, just a couple centimeters diameter. You can set it to remain on top of other windows. Works with Windows 7.
Doesn't measure strength in bps, instead it seems to use a percentage. I don't mind it. Main slightly annoying thing is that you have to download yahoo widgets or something like that to use it because it's a widget file.
This can make wifi a bit less painful of an experience to use. Seems to be a good piece of freeware.

Actually, having tried it out some more, there are more problems with this that will be another throbbing vein for frustrated wifi users: It sticks and is slow to update and the meter is backwards.
Updated on Jan 18, 2011Hmm, this is an odd product. I might have to change my mind about recommending it. It seems you need to re-download this EVERYDAY or it won't work....
