Frequently Asked Questions
Q. What if I don’t subscribe to cable TV?
A. If cable TV is available in your area, data and voice service may be made available with or
without cable TV service. Contact your local cable company for complete information on cable
services, including high-speed internet access.
Q. How do I get the system installed?
A. Professional installation from your cable provider is strongly recommended. They will ensure
proper cable connection to the modem and your computer. However, your retailer may have
offered a self installation kit, including the necessary software to communicate with your cable
ISP.
Q. Once my Residential Voice Gateway is connected, how do I get access to the Internet?
A. Your local cable company provides your internet service*, offering a wide range of services
including email, chat, and news and information services, and a connection to the World Wide
Web.
Q. Can I watch TV, surf the Internet, and talk to my friends through the Residential Voice
Gateway at the same
time?
A. Absolutely!
Q. What do you mean by “Broadband?”
A. Simply put, it means you’ll be getting information through a “bigger pipe,” with more
bandwidth, than a standard phone line can offer. A wider, “broader” band means more
information, more quickly.
Q. What is EURO-DOCSIS/DOCSIS and what does it mean?
A. “Data over Cable Service Interface Specifications” is the industry standard that most cable
companies are adopting as they upgrade their systems. Should you ever decide to move, the
Cable Modem will work with all upgraded cable systems that are
EURO-DOCSIS/DOCSIS-compliant.
Q. What is Euro-PacketCable/PacketCable and what does it mean?
A. Like DOCSIS, Euro-PacketCable/PacketCable is the industry standard for telephony services
that most cable companies are adopting as they upgrade their systems. Should you ever decide

to move, the Residential Voice Gateway will work with all upgraded cable systems that are
Euro-PacketCable/PacketCable-compliant.
Q. What is SecureEasySetup and what does it mean?
A. The software radically simplifies Wi-Fi® wireless LAN configuration, allowing even first-time
Wi-Fi users to setup and secure their wireless networks with the push of a button. Whereas a
typical Wi-Fi installation requires a user to manually configure several technical settings on each
wireless device, SecureEasySetup simply requires a user to push a button on the wireless router/
Access Point, and a corresponding button on the PC or other client device. This automates the
connection process and activates Wi-Fi Protected Access (WPA), the strongest security standard
available to protect home and small business wireless networks from unauthorized use.
Q. What is Xpress Technology and what does it mean?
A. It is one of the popular performance-enhancing WiFi technologies, designed to improve
wireless network efficiency and boost throughput. It is more efficient in mixed environments,
and it can work with 802.11a/b/g networks. When Xpress is turned on, aggregate throughput
(the sum of the individual throughput speeds of each client on the network) can improve by up to
27% in 802.11g-only networks, and up to 75% in mixed networks comprised of 802.11g and
802.11b standard equipment. The technology achieves higher throughput by by re-packaging
data, reducing the number of overhead control packets, so that more useful data can be sent
during a given amount of time.

General Troubleshooting
You can correct most problems you have with your product by consulting the troubleshooting
list that follows.
I can’t access the internet.
z
Check all of the connections to your Residential Voice Gateway.
z
Your Ethernet card or USB port may not be working. Check each product’s
documentation for more information.
z
The Network Properties of your operating system may not be installed correctly or the
settings may be incorrect. Check with your ISP or cable company.
All of the lights are flashing in sequence.
z
This means the Residential Voice Gateway is automatically updating its system software.
Please wait for the lights to stop flashing. The updating process typically lasts less than
one minute.
z
Do not remove the power supply or reset the Residential Voice Gateway during this
process.
I can’t get the modem to establish an Ethernet connection.
z
Even new computers don’t always have Ethernet capabilities – be sure to verify that your
computer has a properly installed Ethernet card and the driver software to support it.
z
Check to see that you are using the right type of Ethernet cable.
The modem won’t register a cable connection (CABLE LINK light not on continuously).
z
If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your
Cable Company if it has not completed this 5-step process within 30 minutes, and note
which step it is getting stuck on. (See page 24 for details.)
z
The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable
other than one your Cable Company recommends, or if the terminal connections are
loose, it may not work. Check with your Cable Company to determine whether you’re
using the correct cable.

z
If you subscribe to video service over cable, the cable signal may not be reaching the
modem. Confirm that good quality cable television pictures are available to the coaxial
connector you are using by connecting a television to it. If your cable outlet is “dead”,
call your Cable Company.
z
Verify that the Cable Modem service is DOCSIS-compliant and PacketCable-compliant
by calling your cable provider.
I don’t hear a dial tone when I use a telephone.
z
Telephone service is not activated. If the rightmost light on the Residential Voice
Gateway stays on while others flash, check with your TSP or cable company.
z
If the Residential Voice Gateway is connected to existing house telephone wiring, make
sure that another telephone service is not connected. The other service can normally be
disconnected at the Network Interface Device located on the outside of the house.
z
If using the second line on a two-line telephone, use a 2-line to 1-line adapter cable.
