Correct.

However, since they upgraded us to a two way cable modem, they do not supply
a dns IP.

On AT&T's web site, they actually state to disable DNS for windows 9x users.
dnscache shouldn't interfer with that should it?

dnscache only.  However I do not recall ever doing any configuration for that.
I am using basic Dachstein with the following packages;

root            4.0.6                                                        
etc             4.0.1                                                        
ramlog          1.1        
local           4.0.6 
modules         4.0.6 
dhclient        2.0pl5 
dhcpd           2.0pl5  
dnscache        1.05a 
weblet          1.2.0 
psentry         1.0
libz                                                                         
sshd            3.0p1           
ssh             3.0p1

I do not know enough to say I know for sure, but I believe the 
configuration problem lies in ATTBI's area.  See, when I have these "unable
to connect to the net" problems, so does everyone else in my neighborhood,
it has been documented - plus I know of some people with slightly 
different IP numbers than mine that are AT&T customers and they have
connection problems at the same time I do.  All I do, is check weblet out to
see what is going on, and thats the only thing I find out of the ordinary is
multiple established connections to my router, to external port 53 domain
servers.

Guitarlynn sent me this info;

"By default Dachstein has:

## UDP Services open to outside world
# Space seperated list: srcip/mask_dstport
# NOTE: bootpc port is used for dhcp client
EXTERN_UDP_PORTS="0/0_domain 0/0_bootpc"

Remove the "0/0_domain" entry, but leave the "0/0_bootpc" 
if you are using DHCP to connect to your ISP. I have had this
problem once or twice.... other DNS servers are trying to connect
to your DNS server on the router (dnscache, tinydns, bind, whatever).
I've never had it choke out a router, but dropping the open port will
stop them."

I did just that, and so far so good.  Even the net seems to be a tad
faster now.

Not too sure what is going on.  Just seems odd that when our ability to connect
to the web is shot, everybody elses seems to be also.  Can't imagine my
lil ole LRP router is bringing down the Internet in the Minneapolis area!

Thanks for your help again Michael
