ADSL and DNS Debugging

In my setup Internet connections are sometimes apparently slow and sometimes fail DNS lookup. The problem turned out to be because the default /etc/resolv.conf used the ADSL Modem/Router as the DNS (and this file was updated automatically at around 9:30am each day to):

Changing it back to:
fixes the DNS problems. The router seems to correctly identify the DNS itself ( but somewhere things don't work. This is overridden in /etc/dhcp3/dhclient.conf by adding the two lines:
send host-name "athene.togaware.com";
supersede domain-name-servers;

Perhaps the router is smart enough to do local DNS with athens mapped appropriately? If so, then don't need the static (but possibly changing) entries in /etc/hosts.
