How Do I Arrange for Installation?
Call your service provider to inquire about professional installation. A professional
installation ensures proper cable connection to the residential gateway and to your
PC, and it ensures the proper configuration of all hardware and software settings.
Contact your service provider for more information about installation.
How Does the Wireless Residential Gateway Connect to My Computer?
The residential gateway connects to the 10/100/1000BASE-T Ethernet port on your
PC. To use the Ethernet interface, Ethernet cards available from your local PC or
office supply retailer, or from your service provider. For best performance over an
Ethernet connection, your PC should be equipped with a Gigabit Ethernet card.
After My Wireless Residential Gateway Is Connected, How Do I Access the
Internet?
Your local service provider becomes your Internet Service Provider (ISP). They offer
a wide range of services including e-mail, chat, news, and information services. Your
service provider will provide the software you will need.
Can I Watch TV and Surf the Internet at the Same Time?
Absolutely! If you subscribe to cable television service, you can watch TV and use
your residential gateway at the same time by connecting your TV and your
residential gateway to the cable network using an optional cable signal splitter.

Common Troubleshooting Issues
This section describes common problems and offers solutions.
I don't understand the front panel status indicators
See
Operation of Front Panel Indicators
(on page 17), for more detailed information
on front panel LED status indicator operation and function.
The Wireless Residential Gateway does not register an Ethernet connection
Try one of the following solutions:
Verify that your computer has an Ethernet card and that the Ethernet driver
software is properly installed. If you purchase and install an Ethernet card,
follow the installation instructions very carefully.
Verify the status of the front panel status indicator lights.
The Wireless Residential Gateway does not register an Ethernet connection after
connecting to a hub
If you are connecting multiple PCs to the residential gateway, you should first
connect the residential gateway to the uplink port of the hub using the correct
crossover cable. The LINK LED of the hub will illuminate continuously.
The Wireless Residential Gateway does not register a cable connection
The residential gateway works with a standard, 75-ohm, RF coaxial cable. If you are
using a different cable, your residential gateway will not function properly. Contact
your service provider to determine whether you are using the correct cable.

Tips for Improved Performance
If your residential gateway does not perform as expected, the following tips may
help. If you need further assistance, contact your service provider.
Verify that the plug to your residential gateway AC power is properly inserted
into an electrical outlet.
Verify that your residential gateway AC power cord is not plugged into an
electrical outlet that is controlled by a wall switch. If a wall switch controls the
electrical outlet, make sure the switch is in the
ON
position.
Verify that the
ONLINE
LED status indicator on the front panel of your
residential gateway is illuminated.
Verify that your cable service is active and that it supports two-way service.
Verify that all cables are properly connected, and that you are using the correct
cables.
If you are using the Ethernet connection, verify that your TCP/IP is properly
installed and configured.
Verify that you have called your service provider and given them the serial
number and MAC address of your residential gateway.
If you are using a cable signal splitter so that you can connect the residential
gateway to other devices, remove the splitter and reconnect the cables so that the
residential gateway is connected directly to the cable input. If the residential
gateway now functions properly, the cable signal splitter may be defective and
may need to be replaced.
If you are connected to your PC with an Ethernet connection, your PC should be
equipped with a Gigabit Ethernet card for best performance.
