connections). check box is cleared.
Try to access multipl e Web sites to check whether the terminal can access these Web sites.
If the term inal still cannot access Web sites, contact your network service provider.
What can I do if Web pages often cannot be displayed during Web page browsing

Step 3
Ensure that the terminal and other devices, such as telephones or fax machines, are connected to telephone lines through a splitter.
For detail s 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 improp erly connected, the stability of the network connection is affected.
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 o r electric fields.
If the problem persists, contact your service provider.
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
Check the positions of your terminal and your computer. Ensure are far from the electric appliances, such as microwave ovens,
that they 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 sig nals 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 the WLAN during thunderstorms.
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.
