I managed to try it on a laptop with a pcmcia wireless card.
Booting with the card in was interfering with a wired connection.
I tried a vasm > netconf a couple of times, but no wired network as long as the wireless card was in.
Needed to reboot and take the pcmcia card out to get the wired.
Wicd handled this very well, connecting automatically to the wired one, but displaying the available wireless networks at the same time.
And with quite a lot of information (essid, bssid, encryption method, signal quality).
It seemed to be a very straightforward process to connnect (just write the WEP key), but I couldn't actually try it, as none of those networks were mine.
The scanning part went fine, though.
Looks like it is a great little tool.
