To restore the default settings, press and hold the RESET button on the rear panel for over six seconds after the HG521 is powered on, and then release the button. What can I do if I cannot access the Internet through the terminal? Step 1 Check whether the POWER indicator on the terminal is solid on. If the POWER indicator is off, perform further checks as follows: 1. Ensure that the terminal is turned on. 2. Ensure that electricity comes from the socket and that the power input from the socket meets the requirements described on the label of the terminal power adapter. If the voltage is unsteady, for example, if the voltage is too high or too low, do not use the terminal. Wait until the voltage restores to its normal level, and then use the terminal. 3. Ensure that the terminal is properly connected to the socket through 14

In this case, re-install the driver for the network adapter of the computer. Ensure that you have entered the correct usare required by the PPP dial-up software. The user n15
Step 6 Check whether you can use the PPP dial-up software to dial successfully.If you cannot use the PPP dial-up software to dial successfully, perform further checks as follows: 1. Stop the PPP dial-up software and then power off the terminal. After five minutes, power on the terminal, and then use the PPP dial-up software to dial again. 2. Restore the default settings of the terminal. If the problem persists, contact your network operator. Step 7 Check whether the proxy server of the Web browser is correctly configured. Take the Internet Explorer installed on a computer that runs Windows XP as an example. To check whether the proxy server of the Web browser is correctly configured, do as follows: 1. Launch the Internet Explorer. 2. Choose Tools > Internet Options. 3. In the Internet Options dialog box, click the Connections tab. 4. In the Local Area Network (LAN) settings group box, click LAN Settings. 5. In the Proxy server group box of the Local Area Network (LAN) Settings dialog box, ensure that the Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections). check box is cleared. Step 8 Try to access multiple Web sites to check whether the terminal can access these Web sites. If the terminal 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 and can be displayed after the terminal is restarted? Step 1 Ensure that the terminal and other devices, such as telephones or fax machines, are connected to telephone lines through a splitter. For details about how to install a splitter, see the related description in the manual. Step 2 Ensure that telephone lines are properly connected. If the telephone lines are improperly connected, the stability of the network connection is affected. 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. 16
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. 17
