Take a close look at what gets logged into /var/log/messages
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?
