5 FAQs
What can I do if I cannot visit Web sites through the terminal?
Step 1 Check whether the POWER indicator of the terminal is on.
If the POWER indicator is off, perform further checks as follows:
1. Ensure that the power switch of the terminal is turned on.
2. Ensure that electricity comes from the socket and that the input power
of the socket meets the requirements described on the label of the
terminal power adapter. If the voltage is unsteady, for example, if the
voltage is too high or too low, do not use the terminal. Wait until the
voltage restores to its normal level, and then use the terminal.
3. Ensure that the terminal is properly connected to the socket through the
power adapter.
If the POWER indicator is still off, contact an authorized maintenance center.
Step 2 After powering on the terminal, wait for about three minutes. Then check
whether the ADSL indicator of the terminal is on.
If the ADSL indicator blinks for a long time, perform further checks as follows:
1. Ensure that telephone lines are properly connected. Pay special
attention to the connection between the telephone line and splitter.
2. Ensure that terminal cables or telephone lines are far from the electric
appliances that generate strong magnetic or electric fields.
3. Replace telephone lines.
If the ADSL indicator still blinks, contact your network operator.
Step 3 Check whether the LAN indicator of the terminal is on.

11
If the LAN indicator is off, perform further checks as follows:
1. Ensure that the network adapter of the computer is enabled.
2. Ensure that the network cable between the terminal and the computer is
properly connected.
3. Remove and then insert the network cable or replace the network cable.
If the LAN indicator is still off, contact an authorized maintenance center.
Step 4 Check whether the driver for the network adapter is properly installed.
Take a computer that runs Windows XP as an example. To check whether the driver
for the network adapter is installed, do as follows:
1. On the desktop, right-click My Computer and choose Manage.
2. In the navigation tree of the Computer Management window, choose
Device Manager.
3. In the right pane of the Computer Management window, click
Network adapters to view the information about the network adapter
of the computer.
If no network adapter is found or if a question mark (?) or an exclamation mark (!) is
displayed next to the icon of the network adapter, you can infer that the driver for the
network adapter is not properly installed. In this case, re-install the driver for the
network adapter of the computer.
Step 5 Ensure that you have entered the correct user name and user password that
are required by the PPP dialing software.
The user name and the user password are provided by your network operator.
Step 6 Check whether you can use the PPP dialing software to dial successfully.
If you cannot use the PPP dialing software to dial successfully, perform further
checks as follows:
1. Stop the PPP dialing software and then power off the terminal. After
five minutes, power on the terminal and use the PPP dialing software to
dial again.
2. Restore the default settings of the terminal.
If the problem persists, contact your network operator.
Step 7 Check whether the proxy server of the Web browser is correctly
configured. Take the Internet Explorer installed on a computer that runs
Windows XP as an example. To check whether the proxy server of the Web
browser is correctly configured, do as follows:
1. Launch the Internet Explorer.
2. Choose Tools > Internet Options.
3. In the Internet Options dialog box, click the Connections tab.
4. In the Local Area Network (LAN) settings group box, click LAN
Settings.
5. In the Proxy server group box of the Local Area Network (LAN)

12
Settings dialog box, ensure that Use a proxy server for your LAN
(These settings will not apply to dial-up or VPN connections).
check box is not selected.
Step 8 Try to access multiple other Web sites to check whether the terminal can
access.
If the terminal still cannot access other Web sites, contact your network service
provider.
What can I do if Web pages often cannot be displayed during Web page browsing and
can be displayed after the terminal is restarted?
Step 1 Ensure that the terminal and other devices such as telephones or fax
machines are connected to the telephone line through a splitter.
For details about how to install a splitter, see the related description in the manual.
Step 2 Ensure that telephone lines are properly connected.
If the telephone lines are improperly connected, the stability of the network
connection is affected.
Step 3 Check the positions of your terminal and computer. Ensure that they are far
from the electric appliances such as microwave ovens, refrigerators, or
cordless telephones that generate strong magnetic or electric fields.
If the problem persists, contact your service provider.
After a broadband terminal is installed, does Internet access degrade call quality or do
telephone calls lower the Internet access rate?
No. The terminal uses the frequency division multiplexing (FDM) and splitter
technologies to separate voice signals from data signals. Although the two types of
signals are transmitted through one telephone line, they are carried by different
frequency bands. Therefore, they do not interfere with each other. In this case, you
can make a telephone call and access the Internet at the same time, without degrading
call quality or lowering the Internet access rate.
How can I quickly restore the default settings of the terminal?
To restore the default settings of the terminal, power on the terminal, press and hold
the RESET button for a while, and then release the RESET button.
