[vox-tech] Wired & Wireless connection problems - Jaunty KDE4.3

[Thomas Johnston]

Under Wicd -> preferences -> external programs, I tried selecting
dhclient and dhcpcd (instead of automatic) but neither option made a
difference.

But, my labmate has a live CD of karmic koala.  I booted that (making
no permanent changes to my computer) and the wired connection worked
immediately.  However, no wireless connections were available.  Via
the wired connection I downloaded & activated the recommended STA
driver for my wireless adapter and then was able to connect to both
moobilenet and the unencrypted wireless AP my labmate has running in
our lab.  (I couldn't connect to moobilenetx, but if I played around
with the settings I could probably get that working, too).

I have NO desire to upgrade to karmic at the moment.  Knowing this,
what would you now recommend?
