Before installing you new wireless eMTA, you must contact your local cable service provider to

activate your Internet access. Be sure to have the wireless eMTA MAC address available, which

can be found on the underside of the wireless eMTA.

Before installing your wireless eMTA, you should first prepare your area. To do this:

1)

Locate your cable outlet and ensure that it is located within proper distance

of your wireless eMTA and computer. Be sure not to bend the cable as this

may strain the connector and cause damage.

2)

Place wireless eMTA as high as possible. Allow sufficient airflow around the

wireless eMTA to prevent overheating.

3)

Place wireless eMTA and wireless clients in open areas or far away from

transformers, heavy-duty motors, microwave ovens, refrigerators, fluorescent

lights, and other manufacturing equipment.

4)

Ensure that the temperature in the room where the wireless eMTA will be

operating is between 0 and 40C (32 and 104F)

5)

The wireless signal may be weaker after it has passed through metal,

concrete, brick, walls, or floors. Also, make sure that the wireless eMTA and

wireless adapters are positioned so that the signal will travel straight through a

wall or ceiling for better reception. For example, a wall that is 1 foot thick, at

a 45-degree angle appears to be almost 2 feet thick.

2. Installing the Modem

This chapter explains the process for installing your wireless eMTA using the Ethernet port. Using

the Ethernet port allows to you connect multiple computers to a wireless eMTA 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 meat’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 eMTA. The wireless eMTA 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 eMTA directly by using Network Interface Card. Unlike USB installation, there is

no needed for software installation for the Ethernet connection.

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

and electrical outlet. To install the hardware:

•

Power off the computer

•

Connect one end of the coaxial cable to the wireless meat’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 eMTA and television to the same wall outlet, you must use a cable

line splitter (not included).

•

Connect one end of the Ethernet cable to the wireless meat’s Ethernet port and the other

end of the cable to the Ethernet port on the PC or network interface card (NIC).

•

Plug the wireless eMTA’s power adapter into the wireless eMTA’s power jack and into a

wall outlet or surge protector.

•

If the Power, Online, and ethernet LEDs are solidly lit, the wireless eMTA is working

properly.

Check the connection between the power adapter and the eMTA. Power off the Wireless

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

exists, you may have a hardware problem.

The ETH 1 or 2 or 3 or 4 LED on my wireless eMTA is not lit.

•

Try restarting the computer so that is could re-establish a connection with the wireless

eMTA.

•

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

•

Right-click on the My Computer icon on your desktop and choose Properties.

•

Click the Device Manager tab and look for a yellow exclamation point or red X over the

NIC in the Network Adapters field. If you see either one, you may have an IRQ conflict.

Refer to the manufactures documentation or you cable service provider for further

assistance.

•

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

•

Power cycle the wireless eMTA by removing the power adapter from the electrical outlet

and plugging it back in. Wait several minutes for the wireless eMTA to re-establish

communications with your cable service provider.

•

Your Ethernet cable may be damaged. Try another Ethernet cable.

All of the LEDs on the front of my modem look correct, but I cannot access the Internet.

•

If the Power & Online LEDs are solidly lit, the wireless eMTA is working properly. Try

restarting the computer so that is could re-establish a connection with the wireless eMTA.

•

Power cycle the wireless eMTA by removing the power adapter from the electrical outlet

and plugging it back in. Wait several minutes for the wireless eMTA to re-establish

communications with your cable service provider.

•

If your PC is connected to a hub or gateway, try connecting the PC directly into the

wireless eMTA.

•

If you are using a cable splitter, try removing the splitter and connect the wireless eMTA

directly to the cable wall outlet. Wait several minutes for the wireless eMTA to re-

establish communications with your cable service provider. Your Ethernet or coaxial

cable may be damaged. Try using another cable.

•

If none of these suggestions work, contact your cable service provider for further

assistance.
