I've got some experience with attbi.com.  Since they went through the
@home debacle, I have had solid internet connectivity, and up to 300K/sec
downloads!

They've sold or provided a gob of bad modems, and the symptoms are about
as you describe.  Internet here one minute, gone the next.  Power cycling
the modem usually works, for a while.

My dhclient.conf file is

initial-interval 1;
request subnet-mask, broadcast address, routers,
	domain-name, domain-name-servers, host name;

But, I make darned sure that my /etc/resolve.conf file isn't changed by
/sbin/dhclient.

I, too, get the same IP everytime I boot with the same system.  Changing
the NIC seems to spawn a new IP.
