Are you connected via a wireless Network? It seems to be that your
networkmanager tries to connect by him self to an available network.
I don't know networkmanager, because I usually use software
controlled by myself. I hate software, whic tries to think like me
;-) But there mustbe an option in networkmanager connect only to the
AP you told him. If you don't use wireless shut networkmanager off.
(the best would be to thrown it away)
