A long answer might be Kismet (http://www.kismetwireless.net/) Useful
for many other things aside from signal strength.

I could inundate you with all the experiments and research so far done,
but it really comes down to two more steps. The machine is now in Fedora 8
("F8"? sounds like a function key). I need to hand load the driver and see
is I can get it up. If I succeed, I need to test whether it, too, sufferes
from the original problem, inability to pick up a signal from the router
unless it's in the same room.
Any hints on testing to see signal stength received?
What's the device name?
/sbin/ifconfig -a
(is it wlan0, maybe?)
/sbin/iwlist wlan0 scan
If this gives
wlan0 No scan results
try
sudo /sbin/ifconfig wlan0 up
(this should make the word "UP" appear in the output of
/sbin/ifconfig wlan0
I'm told that the signal strengths reported by wireless devices is
somewhat (largely) uncalibrated -- possibly they should be only taken as
relative strengths, and only meaningful for _that_ particular hardware.
Maybe others have more scoop on that?
Anyways,
iwlist [device] scan
is the short answer.
