John,

   No difference. Tried with Xubuntu-11.10 live CD, too.

   It's almost certainly not hardware because the system sees WAPs but with
WICD could not send packets over wlan0 because eth0 had routes with lower
metric numbers. With NM there are no eth0 routes when that interface is not
active. In the next day or so I'll take the Sony to a local coffee shop and
see if it can connect and communicate after being manually started by root
running 'ifconfig wlan0 up.'

More when I have it,
