The question is: Is the cable modem using standard ethernet. Sometimes
Intel chipsets are used in nonstandard ways, such as reduced clock rates.

This is what I can tell you about Ethernet compatibility. I can boot a
given machine to Linux, win3.x, or w95 and use TCP/IP over Ethernet. With
all 3 operating systems I can access the internet via another Linux box
which has a modem and is configured to serve as a gateway/router or
expensive Cisco routers with T-1 bandwidth. In both win3.x and win95 the
standard Microsoft drivers are used.

So if the cable modem is usable with standard Microsoft drivers, it will
probably work with Linux. If there is no Linux driver for the card, try a
card that is widely supported. I paid $18 for new ethernet cards last
year.

If you always get the same IP address, then it is static. Write it down
and use it as your machine IP for Linux.
