Question 5:

What can I do if noises exist during telephone calls?

Step 1

Ensure that a splitter is installed.

A splitter helps to protect the call quality of the asymmetric digital subscriber line

(ADSL) from being affected due to the interference of other type of signals.

Step 2

Ensure that telephone cables are properly connected. Especially ensure that the

telephone cable connecting to the splitter is properly connected.

Step 3

Replace telephone cables and ensure that the telephone cables are not faulty.

Step 4

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.

Question 6:

What can I do if the terminal cannot access the Internet through

a wireless network adapter?

Step 1

Ensure that the power cables and telephone cables of the terminal are properly

connected.

Step 2

Check whether the Wi-Fi indicator of the terminal is on.

If the Wi-Fi indicator is off, you can infer that the wireless local area network (WLAN)

function of the terminal is disabled. In this case, enable the WLAN function.

For details about how to enable the WLAN function, see the manual of the terminal.

Step 3

See the description of the wireless network adapter that is installed on the computer and

check whether the wireless network adapter supports the 802.11b, 802.11g and 802.11n

protocols.

If the wireless network adapter does not support the 802.11b, 802.11g and 802.11n

protocols, replace it with the network adapter that supports the protocols.

Step 4

Check whether the driver for the wireless network adapter is properly installed on the

computer.

If the driver is improperly installed, install it properly.

Step 5

Check whether the computer can receive the signals of a WLAN.

Take a computer that runs Windows XP as an example. To check whether the computer

can receive the signals of a WLAN, do as follows:

1.

In the

Control Panel

window, double-click

Network Connections

to display the

Question 7:

What can I do if sometimes the terminal cannot access the

Internet through a wireless network adapter or if the WLAN

connection is unsteady?

Step 1

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.

Step 2

Place your terminal in an open position.

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.

Step 3

Place your computer close to your terminal.

If your computer is far from your terminal, the effects of the WLAN are affected.

Step 4

Place your terminal and computer in another direction.

Step 5

Do not use your terminal to access a WLAN during thunderstorms.
