Alexander, added my syslog. The problem shows most probably in the last one ("Earlier syslog of yesterday"). Later yesterday I have replaced my /etc/network/interfaces by the standard one of my Feisty box and the problem disappeared. It seems that Network Manager gets irritated a lot when one uses a manual configuration temporarily. Is there no possibility to cleanly get back to automatic using the GUI tools?
