Deciding Which Installation Process to Use

The 3Com
connect to the Internet using either the USB port or the
Ethernet port. Be sure to follow the instructions provided
for the port that you want to use.
Using the USB port to connect to the Internet allows you to
install the cable modem more quickly and easily than
connecting to the Internet using the Ethernet port, because
you do not need to install a network interface card (NIC).
USB, however, only allows you to use one Internet protocol
(IP) address per cable modem.
Using the Ethernet port allows you to use a hub to connect
multiple computers to the cable modem, and you can use
multiple IP addresses from your cable service provider.
CAUTION: You cannot use the USB and Ethernet
connections simultaneously. Therefore, you should not
have the USB cable and the Ethernet cable plugged into
the cable modem at the same time. Having the USB and
Ethernet cables plugged into the cable modem at the same
time might prevent you from accessing the Internet.
See Chapter 2 "USB Installation" to set up the USB
connection.

Setting Up the Computer to Use an Ethernet Connection

You can use the Ethernet port to connect to the Internet
with the following operating systems: Windows 95,
Windows 98, Windows 2000, or Macintosh 7.5 (or later).
