And the router is the nameserver?
What then is my IP?  Not the dynamic address supplied by the ISP for the 
current session?

Yes - /etc/dhcp3/dhclient.conf:

# Configuration file for /sbin/dhclient, which is included in Debian's
#    dhcp3-client package.
# This is a sample configuration file for dhclient. See dhclient.conf's
#    man page for more information about the syntax of this file
#    and a more comprehensive list of the parameters understood by
#    dhclient.
# Normally, if the DHCP server provides reasonable information and does
#    not leave anything out (like the domain name, for example), then
#    few changes must be made to this file, if any.

I did, Tim and got improved reaction from the leds on the modem - but 
not enough to
prevent timing out...

No wireless, my wife's machine is, as is mine connected to a switch on 
the output side of
the adsl modem.

I did this with no apparent improvement. Up until a couple of weeks ago, 
there were two
ethernet cards in the box, and I took the extraneous one out in case it 
was the problem.

There is no resolvconf on the system.

I did, and many thanks for taking the time to help, but the bloody 
thing's still not working...

Up to date then, ipv6 has been disabled in Firefox and that works.
I've added "blacklist ipv6" to /etc/modprobe.d/blacklist, disabling ipv6 
in the whole system
without any improvement in the performance of both evolution and 
synaptic package
manager, dhclient.conf and interfaces have been modified as noted above 
and we're still
in the shit!

There are a couple of questions nagging at me:
    While it would be good to at least get ubuntu running properly (and 
please don't give up
on me about that), am I right in my assumption that internet access is 
being unsuccessfully
attempted during the installation process? And if so, getting the system 
up afterwards is not
solving the real problem? In other words, could it relate to a faulty 
adsl modem?
No, that can't be right - the other three systems work fine.
Evolution could be made to work by entering the ip addresses ot the pop 
and smtp servers
but Synaptic Package manager is the bugbear...

What the hell's going on with it all? Where do we go from here?
