5. Installing the Modem Using the Ethernet Port

This chapter explains the process for installing your wireless cable modem using the

Ethernet port. Using the Ethernet port allows to you connect multiple computers to a

wireless cable modem through the use of additional equipment which is not included. Please

contact your cable service provider for more information on using multiple computers.

You can use the wireless cable modem

’

s Ethernet port if you have:



A PC running Windows 95 (or later) operating system or a Macintosh computer

running system 7.6 (or later) operating system



An active Ethernet port on your PC

Before you begin, verify that your Network Interface Card (NIC) has been installed and

configured for use with your wireless cable modem. The wireless cable modem requires TCP/IP

to be installed. Contact your cable service provider for assistance with installing and configuring

TCP/IP. After installed the hardware, your computer can connect the wireless cable modem

directly by using Network Interface Card. Unlike USB installation, there is no needed for software

installation for the Ethernet connection.

Installing the Hardware

This section explains how to connect the wireless cable modem to the computer, wall cable outlet,

and electrical outlet.

To install the hardware:

1)

Power off the computer

2)

Connect one end of the coaxial cable to the wireless cable modem

’

s cable connector.

Connect the other end of the coaxial cable to the cable wall outlet. Be sure not to bend

or over tighten the cables as this may strain the connector and cause damage. If you

plan to connect the wireless cable modem and television to the same wall outlet, you

must use a cable line splitter (not included).

3)

Connect one end of the Ethernet cable to the wireless cable modem

’

s Ethernet port

and the other end of the cable to the Ethernet port on the PC or network interface card

(NIC).

4)

Plug the wireless cable modem

’

s power adapter into the wireless cable modem

’

s

power jack and into a wall outlet or surge protector.

5)

If the pwr, sync, ready, and ethernet LEDs are solidly lit, the wireless cable modem is

working properly.

Troubleshooting the Ethernet Installation

1. None of the LEDs are on when I power on the Wireless LAN Cable Modem.

Check the connection between the power adapter and the cable modem. Power off the Wireless

LAN Cable Modem and wait for 5 seconds and power on the modem again. If the problem still

exists, you may have a hardware problem.



Check for a resource conflict (Windows users only). To do this:

Right-click on the

icon on your desktop and choose

2)

Click the

tab and look for a yellow exclamation point or red

X over the NIC in the

field. If you see either one, you may

have an IRQ conflict. Refer to the manufacturer

’

s documentation or you

cable service provider for further assistance.



Verify that TCP/IP is the default protocol for your network interface card (NIC)
