, 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.

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.

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,

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.

8.

Check that the proxy server of the browser is correctly configured. The following example uses

Internet Explorer on the Windows 7 operating system to check whether the proxy server of the

browser is correctly configured:

a.

Launch Internet Explorer.

b.

Choose

Tools

>

.

c.

In the

Internet Options

dialog box, click the

tab.

d.

In the

Local Area Network (LAN) settings

area, click

area of the

Local Area Network (LAN) Settings

dialog box, check that the

Use a

proxy server for your LAN (These settings will not apply to dial-up or VPN connections).

Check box

is cleared.

9.

Try to access more websites to check whether the HG658 V2 can access these websites. If the

problem persists, contact your network service provider.

Verify the following:

1.

Cables are securely connected to HG658 V2 ports. Otherwise, network stability may suffer.

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.

If the problem persists, contact your Internet Service Provider.

•

Wireless MAC address filtering: controls whether a computer can connect to the HG658 V2 over the

WLAN.
