16 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 af fected 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 com puter in another direction. Step 5 Do not use your terminal to access the WLAN during thunderstorms. After a broadband terminal is installed, do es Internet access degrade call quality or do telephone calls lower the Internet access rate? No. The terminal uses the frequency di vision multiplexing (FDM) and splitter technologies to separate voice signals fro m 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 interfe re with each other. In this case, you can make a telephone call and access the Internet simu ltaneously, without degrading call quality or lowering the Internet access rate.
