6 FAQs
How can I quickly enable or disable the wireless network function?
Press and hold the WLAN button for over one second, and then release the button to
enable or disable the wireless network function. The WLAN indicator shows
whether the wireless network function is enabled.
How can I quickly restore the default settings of the terminal?
To restore the default settings, press and hold the RESET button on the rear panel
for over six seconds after the HG520c is powered on, and then release the button.
What can I do if I cannot access the Internet through the terminal?
Step 1
Check whether the POWER indicator on the terminal is solid on.
If the POWER indicator is off, perform further checks as follows:
1. Ensure that the terminal is turned on.
2. Ensure that electricity comes from the socket and that the power input
from the socket meets the requirements described on the label of the
13
Step 2
Step 3
Step 4
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.
After powering on the terminal, wait for about three minutes. Then, check
whether the ADSL indicator on the terminal is solid 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 connections between the telephone lines and the
splitter.
2. Ensure that the terminal or telephone lines are far from the electric
appliances that generate strong magnetic or electric fields. Replace
telephone lines when necessary.
If the ADSL indicator still blinks and does not turn solid on, contact your
network operator.
Check whether the LAN indicator of the terminal is on.
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. Remove and then insert the network cable or
replace the network cable when necessary.
If the LAN indicator is still off, contact an authorized maintenance center.
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 then 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 7
Step 8
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
Step 2
Ensure that you have entered the correct user name and user password that
are required by the PPP dial-up software.
The user name and the user password are provided by your network
operator.
Check whether you can use the PPP dial-up software to dial successfully.
If you cannot use the PPP dial-up software to dial successfully, perform
further checks as follows:
1. Stop the PPP dial-up software and then power off the terminal. After
five minutes, power on the terminal, and then use the PPP dial-up
software to dial again.
2. Restore the default settings of the terminal.
If the problem persists, contact your network operator.
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)
Settings dialog box, ensure that the Use a proxy server for your
LAN (These settings will not apply to dial-up or VPN
connections). check box is cleared.
Try to access multiple Web sites to check whether the terminal can access
these Web sites.
If the terminal still cannot access Web sites, contact your network service
provider.
Ensure that the terminal and other devices, such as telephones or fax
machines, are connected to telephone lines through a splitter.
For details about how to install a splitter, see the related description in the
manual.
Ensure that telephone lines are properly connected.
If the telephone lines are improperly connected, the stability of the
network connection is affected.

Step 3
What can I do if sometimes the terminal cannot access the Internet through a WLAN
connection or if the WLAN connection is unsteady?
Step 1
Step 2
Step 3
Step 4
Step 5
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 simultaneously, without degrading
call quality or lowering the Internet access rate.
Check the positions of your terminal and your computer. Ensure that they
are far from 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.
Check the positions of your terminal and your 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.
Place your terminal in an open area.
Although radio signals can pass through obstacles, the transmission
effects of WLAN radio signals are affected if radio signals pass through
too many obstacles, such as cement or wooden walls.
Place your computer close to your terminal.
If your computer is far from your terminal, the effects of the WLAN are
affected.
Place your terminal and computer in another direction.
Do not use your terminal to access the WLAN during thunderstorms.
