How Many Ethernet Network Devices Can I Connect?

The cable modem gateway can support several Ethernet network devices using either the 4 Ethernet ports on the back panel of the unit, or external Ethernet hubs that must be purchased separately. The theoretical maximum number of Ethernet network devices supported is by the cable modem gateway 253. However, under normal circumstances, the number of devices connected should be a much lower number. Contact your cable service provider for more information on the maximum number of Ethernet network devices to connect to the cable modem gateway in order to maintain optimal network performance.

What are the Wiring Requirements for Ethernet Networking?

Although the cable modem gateway 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 10/100 BaseT CAT-5 Ethernet hubs is 382 feet (100 meters). Scientific-Atlanta recommends that you use CAT-5 Ethernet cables.

A number of factors can impact the practical limit of the network. Contact your cable service provider or consult the documentation for your Ethernet network devices for more information.

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.
