, and ensure
that all check boxes are deselected.
2.
Check that the computer IP address is 192.168.1.*. (* is any integer from 2 to 254.)
3.
Check that the cables are securely connected to the HG658 V2.
If the problem persists, restore the HG658 V2 to its default settings.
What Can I Do If the HG658 V2 Cannot Access the Internet
through a Wireless Network Adapter Sometimes or If the WLAN
Connection Is Unsteady?
This is probably because the HG658 V2 has its cables connected loosely, is placed too close to
electronic appliances with intensive interference, or is too far from the computer. Verify that:
1.
The power and telephone cables are correctly connected to the HG658 V2.
2.
Your computer and the HG658 V2 are far from electric appliances that generate strong magnetic or
electric fields, such as microwave ovens, refrigerators, and cordless telephones.
3.
The HG658 V2 is in an open area, and there are no obstacles, such as concrete or wooden walls,
between the HG658 V2 and computer.
4.
The HG658 V2 is close to the computer.
5.
The angle between the HG658 V2 and computer is appropriate.
Do not use the HG658 V2 during thunderstorms, as the signal strength may be unsteady and
the HG658 V2 itself may be damaged due to lightning strikes.
What Can I Do If I Cannot Access the Internet?
1.
Check that the
Power
indicator on the HG658 V2 is steady on. If the
Power
indicator is off, perform
further checks as follows:
a.
Check that the HG658 V2 is turned on.
b.
Check that electricity comes from the socket and that the power input from the socket meets
the requirements described on the label of the HG658 V2's power adapter. If the voltage is unstable,
Page 47 / 54
44
for example, if the voltage is too high or too low, do not use the HG658 V2. Wait until the voltage recovers,
and then use the HG658 V2.
c.
Check that the HG658 V2 is securely connected to the socket using its power adapter.
If the
Power
indicator is still off, contact an authorized maintenance center.
2.
After powering on the HG658 V2, wait for about 3 minutes. Then check whether the
WAN
indicator turns steady on.
a.
Check that the telephone line is correctly and securely connected, especially the connection
between the telephone line and the splitter.
b.
Check that the HG658 V2 and telephone line are located far from any electric appliances that
generate strong magnetic or electric fields. Replace the telephone line when necessary.
If the
WAN
indicator is still off, contact your network service provider.
3.
Check whether the
LAN
indicator is on. If the
LAN
indicator is off, perform further checks as
follows:
a.
Check that the network adapter on your computer is enabled.
b.
Check that the network cable between the HG658 V2 and the computer is securely 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.
4.
Check that the driver for the network adapter is correctly installed. The following example uses a
computer running the Windows 7 operating system to check whether the driver for the network
adapter is installed:
a.
Right-click
My Computer
, and choose
Manage
from the displayed shortcut menu.
b.
In the
Computer Management
window, click
Device Manager
.
c.
In the right pane of the
Computer Management
window, click
Network adapters
.
If no network adapter is found or if a question mark (?) or an exclamation mark (!) is displayed next
to the network adapter icon, the driver for the network adapter is not correctly installed. Re-install
the driver.
5.
Check that PPP dial-up software is installed and parameters are set correctly. For details about
parameter settings, see the user guide for the PPP dial-up software.
6.
Check that you have entered the correct user name and password required by the PPP dial-up
software. The user name and password are provided by your network service provider.
7.
Check that you can use the PPP dial-up software to set up dial-up connection. If the dial-up
connection fails, perform further checks as follows:
a.
Close the PPP dial-up software, and power off the HG658 V2. After 5 minutes, power on the HG658
V2, and use the PPP dial-up software to dial again.
b.
Restore the HG658 V2 to its default settings.
If the problem persists, contact your network service provider.

Your computer and the HG658 V2 are far from electric appliances that generate strong magnetic or
electric fields, such as microwave ovens, refrigerators, and cordless telephones.
If the problem persists, contact your Internet Service Provider.
What Is the Difference Between Wireless MAC Address Filtering
and MAC Address Filtering?
Wireless MAC address filtering: controls whether a computer can connect to the HG658 V2 over the
