I use KNetworkmanager and it never used to work properly (the icon on the taskbar was a 
grey something-or-other and it always said "No Device Active - or something similar, even 
though my home wireless connection was working just fine!). One day, from a terminal I did:
sudo iwlist wlan0 scan
and is if by magic, the KNetworkmanager icon turned to a 'blue 4 column bar graph' and now 
automatically detects available networks. Just a right click on the icon, then click on 
the available connection that I want to use and 'Bob's your Uncle'!

HTH.
