What I might try is to reset the router to its default setup and see if DHCP/DNS works OK then. It has a *lot* of customisation at the moment because it has a number of routes through the firewall *and* it's doing load balancing with a second router (the 2820n has a second WAN port which you can connect another router to).
I have just tried the default router set up. I rebooted the router to the default factory configuration and then the only change I made was to add the login details of my ADSL. It still doesn't do local DNS even though the router comes up configured as a DHCP server.
The symptom from my Xubuntu system when I boot it is a message saying:-
Could not look up internet address for chris. This will prevent Xfce from operating correctly. It may be possible to correct the problem by adding chris to the file /etc/hosts on your system.
Not very helpful really, I can't add chris to /etc/hosts unless I give chris a static address can I? The system certainly has 'chris' as its hostname and 'chris' is returned in response to entering the hostname command.
What do others here have in their /etc/hosts file? I.e. do you have an entry for the name of the system in /etc/hosts as well as specifying it in /etc/hostname?
I'll need to make very sure I copy the existing configuration though as it would take ages to reconfigure from first principles.
That was OK, the Vigor 2820n makes it very easy to save and restore its configuration.
