What Are the Requirements for Ethernet Network Devices?

How Many Ethernet Network Devices Can I Connect?
The WebSTAR Cable Modems can support several Ethernet network devices
using external Ethernet hubs that must be purchased separately. The theoretical
maximum number of Ethernet network devices supported is by the cable modem
is 63. However, under normal circumstances, the number of devices connected
should be a much lower number. Contact your service provider for more
information on the maximum number of Ethernet network devices to connect to
the cable modem in order to maintain optimal network performance.
What are the Wiring Requirements for Ethernet Networking?
A number of factors can impact the practical limit of the network. Although the
WebSTAR Cable Modem is designed to support several Ethernet network
devices, it is important to view the characteristics of the entire network and not
just each individual node. The theoretical distance between two 10/100BaseT
CAT-5 Ethernet hubs is 382 feet (100 meters). Contact your service provider or
consult the documentation for your Ethernet network devices for more
information.
Note: Scientific-Atlanta recommends that you use CAT-5 Ethernet cables.
Do I Need to Configure the TCP/IP Protocol on My Computer?
In order for you to use Ethernet network devices on your network, you must have
the TCP/IP protocol properly configured on your PC. Refer to How Do I
Configure TCP/IP Protocol, earlier in this guide, for detailed information on
configuring the TCP/IP protocol.
