If you are still unable to access the Internet after verifying these
settings, please contact your Service Provider Technical Support.
Problem:
The Install software completed installation, but my web browser
doesn’t work.
I am unable to connect to the Internet. The Modem’s “Signal” light is
on and the “Connect” light is on.
Solution:
If the “Signal” light is on, and the “Connect” light is on, but you are unable to
access the Internet, there may be third-party firewall software installed on
the computer attempting to access the Internet. Examples of third-party
firewall software are ZoneAlarm, BlackICE PC Protection, McAfee Personal
Firewall, and Norton Personal Firewall.
If you do have firewall software installed on your computer, please make
sure that you properly configure it. You can determine if the firewall software
is preventing Internet access by temporarily turning it off. If, while the
firewall is disabled and Internet access works properly, you will need to
change the firewall settings to function properly when it is turned on.
Please refer to the instructions provided by the publisher of your firewall
software for instructions on configuring the firewall to allow Internet access.
If you are still unable to access the Internet after disabling any firewall
software, please contact your Service Provider Technical Support.
Problem:
I can’t connect to the Internet wirelessly from my computer but it works if I
use the Ethernet cable.
Solution:
If you are unable to connect to the Internet from a wireless computer,
please do the following:
1. Look at the lights on your Modem. Your Modem’s lights should be as
follows:
The “Power” light should be on.
Page 52 / 58
51
The “Connected” light should be on and not blinking.
The “WAN” light should be either on or blinking.
2. Open your wireless utility software by clicking on the icon in the
system tray at the bottom, right-hand corner of the screen.
3. The exact window that opens will vary depending on the model of
wireless card you have; however, any of the utilities should have a list
of “Available Networks”—those wireless networks it can connect to.
Problem:
My wireless network performance is inconsistent.
Data transfer is sometimes slow.
Signal strength is poor.
I am having difficulty establishing and/or maintaining a Virtual Private
Network (VPN) connection.
Solution:
Wireless technology is radio-based, which means connectivity and the
throughput performance between devices decreases when the distance
between devices increases. Other factors that will cause signal degradation
(metal is generally the worst culprit) are obstructions such as walls and
metal appliances. As a result, the typical indoor range of your wireless
devices will be between 100 to 200 feet. Note also that connection speed
may decrease as you move farther away from the Modem or access point.
In order to determine if wireless issues are related to range, we suggest
temporarily moving the computer, if possible, five to 10 feet away from the
Modem.
Changing the Wireless Channel
- Depending on local wireless traffic and
interference, switching the wireless channel of your network can improve
performance and reliability. The default channel the Modem is shipped with
is channel 11. You may choose from several other channels depending on
your region (see the section titled “Changing the Wireless Channel” on page
41 for instructions on how to choose other channels).
Limiting the Wireless Transmit Rate
- Limiting the wireless transmit rate can
help improve the maximum wireless range and connection stability. Most
wireless cards have the ability to limit the transmission rate. To change this
property, go to the Windows Control Panel, open “Network Connections”
Page 53 / 58

and double-click on your wireless card’s connection. In the “Properties”
dialog, select the “Configure” button on the “General” tab (Windows 98
users will have to select the wireless card in the list box and then click
“Properties”), then choose the “Advanced” tab and select the rate property.
Wireless client cards are usually set to automatically adjust the wireless
transmit rate for you, but doing so can cause periodic disconnects when the
wireless signal is too weak; as a rule, slower transmission rates are more
stable.
Experiment with different connection rates until you find the best one for
your environment; note that all available transmission rates should be
acceptable for browsing the Internet. For more assistance, see your
wireless card’s user manual.

Appendix A: Glossary
1X
One Times Radio Transmission Technology (the “one times”
refers to the frequency spectrum). Supports Internet connections
with data rates up to 153 Kbps. Actual speed depends on the
network conditions. Compare to 1x EV-DO.
1x-EVDO
A high speed standard for cellular packet data communications
Rev. A supports Internet connections with data rates up to3.1
Mbps (downlink from the network) and 1.8 Mbps (uplink to the
network).
Rev. 0 supports Internet connections with data rates up to 2.4
Mbps (downlink from the network) and 153 Kbps (uplink to the
network).
Average data rates are roughly: for Rev. A: 600–1300 Kbps
(downlink from the network) and 300–400 Kbps (uplink to the
network); for Rev. 0: 400–700 Kbps (downlink from the network)
and 40°80 Kbps (uplink to the network).
Actual speed depends on the network conditions. Compare to 1X.
bps
bits per second—The actual data speed over the transmission
medium.
CDMA
Code Division Multiple Access—A wideband spread spectrum
technique used in digital cellular, personal communications
services, and other wireless networks. Wide channels (1.25 MHz)
are obtained through spread spectrum transmissions, thus
allowing many active users to share the same channel. Each user
is assigned a unique digital code, which differentiates the
individual conversations on the same channel.
CDMA 1X
Also known as 1X, this is a high speed standard for CDMA
cellular communications.
dormant
The packet data connection has the logical PPP session left open
while the underlying physical link (the radio channel) is released.
When traffic is to resume, a radio channel is reacquired and the
original PPP session resumes.
