Default timeout problem

I found the response below today online to a question I had.
For some reason I never got the mail. I am not quite clear
on what "DHCP + DFG + 2DNS entries" means when calculating the IP
to set for the router:

Thanks

Try this:
For the NIC on your Comcast router set its ip to one that the dhcp in
the router gives out + DFG + 2 DNS entries. In order to have it static.
I see lots of routers with your problem.

DFG = default gateway
2DNS = primary and secondary dns server addresses
DHCP = Would be your normal assigned ip address from the router on the
nic card that the comcast router hands out.

So now you pick one ip address the router assigns from it's dhcp address
block and create a static ip configuration for your eth0 nic, If the
routers dhcp address block is 192.168.2.2 - 192.168.2.100 pick
192.168.2.10 for the ip.

Now eth0 needs a default gateway which is your routers address maybe
like 192.168.2.1.

Now eth0 needs a primary and secondary DNS entry. If the isp only has
one then use one else you can use the default gateway address of the
router but not recomended because you are having problems so I think you
need the real dns.

If you log into the router you will see or find the dns entries you need
and the dhcp block that is assigned.

Oh, static IP on the computer. Yeah, already did that to no avail.
