wireless roaming

[Ed Jabbour]

Wireless networking is set up via /etc/network/interfaces.  It works fine, 
unless I visit the local coffee shop - different network, so it's a real pain 
to set up.  There must be an easier way - something that lists all available 
networks and asks "which one do you want?" .  I use kde and have tried 
knetworkmanager, kwifimanager and wireless assistant.  None of them does 
that - w/o a connection, no networks are listed.  Any advice, pointers, etc. 
appreciated.
