Sorry couldn't try this out earlier, as my wife went away for a few days 
with the laptop.

Anyway, here goes. To try it out, I stopped the 'network' service and 
started 'NetworkManager' as well as 'NetworkManagerDispatcher'. Laptop 
was not connected to any Ethernet cable. My home access point showed up 
(essid 'zuhause', no encryption). I clicked on it to try to establish a 
connection:

Now I was curious about this, so I tried it on another machine, my 
Buildbox, that also has a wireless card. Similar failure:

Any idea why NetworkManager refuses to connect to my network?
