I heard this happen when people have used "pump" as the dhcp client program
rather than "dhclient". It seems to be that your dhcp lease runs out and it
is not automatically being renewed.
try installing the debian dhcp-client package rather than pump. It comes
with a configuration file (/etc/dhclient.conf), but I have found it works
fine with the default of all possible parameters commented out.
