But that doesn't list available networks. I was talking about
identifying available networks. By doing this, you can at least see if
there's anything out there to connect to.
If you want the gui version, kwifimanager does a pretty decent job of
managing your card and search for existing networks. Gives a good
'picture' of the card status.
for the command line, iwlist gives a good bit of data based on available
iwlist interface scan
kismet is a whole different animal. It requires setting up and configuring.
