I've been using the NetworkManager daemon (in conjunction with the 
knetworkmanager applet for KDE) for wifi in recent years.  (There's also 
a similar applet available for GNOME.)

The combo of the 2 of them basically gives you the kind of wifi 
functionality available in Windows - i.e., view available wireless 
networks, choose a network to connect to, have it prompt you for a key, 
have it remember the key (using KWallet) so that it will automatically 
connect to known networks in the future without you having to re-enter 
the key, etc.

NetworkManager can be a bit kludgey sometimes.  (The daemon crashes on 
me periodically.)  But it generally does the job pretty well.

IIRC, wicd is another applet that does similar, if (k)networkmanager 
doesn't cut it for you.
