Anyting interesting in the output of dmesg after these events?
Might be lots of things. From someone else using your IP to a bad
renewal of a DHCP lease. Try turning on the 'mark' option in
syslogd so that you see a regular pulse in the logs. Then run a
ping into the box from somewhere else. After an episode of the
problem compare the logs. Maybe that will help isolate the problem.
