Mine is not weak signal.  I'm just a few feet from a Netgear WG302 and
nm-applet shows all bars solid and something like 80%. 

My other linux laptop running Sarge and an Apple iBook don't have this
problem.  The linux laptop is not using wpa_supplicant, either.

Can you explain how to generate useful debug logs?  I have an Atheros
a/b/g/n card on a Thinkpad T60p using WPA-PSK.

Also, would it be helpful to disable NetworkManager to manually
config the card?  I'm not clear how to do this (I was using a
prism-based card before without WPA).  Plus, I'm not clear how to
monitor the card to see if there are any drop-outs.  The nm-applet
makes it easy to see when the connection is lost, of course.
