Hello, friend!
1. Use a network cable to connect the LAN port of the DSL home gateway to a PC.
2. Ensure that the Internet Explorer (IE) of the PC does not use the proxy server. The following section considers IE8 as an example to describe how to check whether the IE uses the proxy server.
a) Start the IE, and choose Tools Internet Options from the main menu of the IE window. Then, the Internet Options page is displayed.
b) In the Internet Options page, click the Connections tab, and then click LAN settings.
c) In the Proxy server area, ensure that the Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections). check box is not selected (that is, without the "√" sign). If the check box is selected, deselect it, and then click OK.
3. Set the IP address and subnet mask of the PC. For details.
Default settings:
IP address: 192.168.1.1
Subnet mask: 255.255.255.0
IP address and subnet mask of the PC
Configure the IP address of the PC to be in the same subnet as the LAN IP address of the DSL home gateway.
For example:
IP address: 192.168.1.100
Subnet mask: 255.255.255.0
4. Log in to the web page.
a) Enter http://192.168.1.1 in the address bar of IE (192.168.1.1 is the default IP address of the DSL home gateway), and then press Enter to display the login page.
