i fully agree with JohnH,
the panel applet (i believe it is gnome-network-manager) is just too stupid.
Imagine when you turn on your PC with wireless turned off. No networks are found.
Then you turn on your wireless to search for networks and guess what happens?! - Nothing...
So how do you get to find the network as there is no "refresh" button in the applet?!
You have to click on "Connect to other wireless Network" and type in some crap like "findmesomething". So it is looking for this network which obviously can't be found, but nevertheless that is the way you get the network-manager to search for other networks as well.
I really do believe that this is no good way to search for networks and thus i will try the wifi-radar. Perhaps there could be made some improvements to the network-manager (in fact all it misses is a "refresh" button)
