Although it is cable, we must enter our user name, password, and some
other stuff into  a built-in windows dialer. Of course, that is not
viable for linux users! I assume this is because the infrastructure
provider (the company that provides the modem and the cable coming
into the house) is not the ISP, so we must tell it to which ISP to
connect. I now understand that this may not be a very common setup in
other countries.

DHCP from the router. I put all my login info into a dialer built into
the router, and it connects to the 'net. Then the local machine[s] get
their addresses via DHCP.

In any case, I'd like to know how to connect without a router. Based
upon some testing, the router may in fact be the source of problems-
it is dropping anywhere from 2% to 6% of the packets going through it.
It is a Level1 unit, for those about to buy!
