By your description MAC spoofing is just what the doctor ordered. This ISP
did not vive me any login or pw so MAC seemd to be ised instead. These 2
comps are not going to be on network together

I do not know what exactly the ISP did on my computer, but when I attached
another computer and phoned them for settings, they asked for MAC of that
new computer over the phone and in 10 min it worked without me doing
anythoing on my w2k

Some ISPs detect the MAC address and lock their service access to that
specific one. Routers usually have a feature which allows you to
"copy" this MAC address onto the WAN port.

I have no router. The ISP installed Motorola SB5101E Surfboard cable modem

You are right about TV - this provider provides TV service to me and
recently started offering Internet. I already have their TV cable and a
block which allows it add more cables for Internet
