protocol.
If the wireless network adapter does not support any of the preceding
protocol, replace it.
4. Check whether the driver for the wireless network adapter is correctly
installed.
If the driver is not correctly installed, re-install it using the driver program
provided with the wireless network adapter.
5. Check whether the computer receives wireless signals properly. The
following example uses the computer running the Window XP operating
system to check wireless signal reception:
1) Choose
Start
>
Control Panel.
Double-click
Network Connections
.
2) In the
Network Connections
window, right-click
Wireless Network
Connection
, and choose
View Available Wireless Networks
.
If the computer cannot find the wireless network, move the computer
closer to the HG658c. Check that there are no obstacles, such
as walls, between the computer and the HG658c.
6. Check whether the computer is connected to the HG658c's wireless
network.
On
the
wireless
network
list,
check
whether
the
HG658c's wireless network is displayed as Connected.
7. Try to access more websites to check whether the HG658c can access
these websites.
If you still cannot access the websites, restore the HG658c to its default
settings. If the problem persists, contact your network service provider.
What can I do if sometimes the terminal cannot access the Internet over
a wireless connection or if the wireless connection is unstable?
1. Check the positions of the HG658c and the computer. Ensure that they
are located far from the electric appliances such as microwave ovens,
refrigerators, or cordless telephones that generate strong magnetic or
electric fields.
2. Place the HG658c in an open area.
Although radio signals can pass through obstacles, their transmission is
affected if they pass through too many obstacles such as walls.

3. Move the computer closer to the HG658c.
4.
Place the HG658c and the computer in another direction.
5.
Try to avoid using wireless network connection during thunderstorms.
What can I do if the wireless network is not encrypted but the computer
cannot connect to the wireless network?
1. Delete wireless network configuration from the computer.
The following example uses a computer running the Window XP operating
system:
1) Choose
Start
>
Control Panel
. Double-click
Network Connections
.
2) In the Network Connections window, right-click
Wireless Network
Connection
, and choose
Properties
.
3) In the
Wireless Network Connection Properties
dialog box, click
the
Wireless Networks
tab.
4) In the
Preferred Networks
area, select a wireless network, and click
Remove.
5) Delete all the other wireless network connections from the
Preferred
Networks
area.
6) Click
OK
.
2. Set up an unencrypted wireless network connection.
Does the WPS function have any special requirements on the wireless
encryption settings of the HG658c?
The WPS function can be used only when the security mode of the wireless
network is set to
WPA2-PSK
, or
WPA-PSK/WPA2-PSK
, and the SSID is set
to
SSID1
. It is recommended that you set the security mode to
WPA-PSK/WPA2-PSK
.
What can I do if I cannot set up a wireless connection between the HG658c
and the computer by pressing the
WPS
button?
1. Check that only one computer tries to connect to the HG658c using the
WPS function at a time.
2. Check that the wireless network function and the WPS function in PBC
mode are enabled on the HG658c.

3. Check that the security mode of the wireless network is set to
WPA2-PSK
, or
WPA-PSK/WPA2-PSK
, and
SSID
is set to
SSID1
.
Note that the WPS function is forcibly disabled if the wireless network
uses the Wired Equivalent Privacy (WEP) encryption.
4. Check the positions of the HG658c and the 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.
5. Place the HG658c in an open area.
Although radio signals can pass through obstacles, their transmission is
affected if they pass through too many obstacles such as walls.
What can I do if noises exist during telephone calls?
1. Check that a splitter is installed.
A splitter helps to protect the ADSL call quality from being affected due to
the interference of other signals.
2. Check that telephone lines are securely connected. In particular, ensure
that the telephone line connecting to the splitter is securely connected.
3. Replace telephone lines and ensure that the telephone lines are not
faulty.
After a broadband device is installed, does Internet access degrade call
quality or do telephone calls lower the Internet access rate?
No. The HG658c uses the frequency division multiplexing (FDM) and splitter
technologies to separate voice signals from data signals. Although these 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 telephone calls and access the Internet at
the same time, without degrading call quality or lowering the Internet access
rate.
