If the telephone lines are improperly connected, the stability of the  
network connection is affected.  
14  
 
Step 3 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 or 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 Check the positions of your terminal and your 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 area.  
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 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.
