wireless signal strength (more accurate reading than windows)

NETSTUMBLER is the one. Free. When it works, it's great!

Does not work with all cards/adapters.

I must say, I wish it would work consistently for me. It does not seem to deal well with windows XP zero configuration or something, though as I understand it, that's what it's designed for. It worked for a few weeks for me, then got broken somehow. Sometimes it shows no signal, other times no AP at all, then I turn on XP wireless again and the AP comes right up.

On the "help" and the manual end, there is almost nothing. Wish somebody would do a tutorial. Has a forum, (stumbler.net?) but it appears to shun beginners.

Try it and see!
