Broadband Router Setup assumes that you have already correctly connected all the hardware. We will only cover how to configure the broadband router to enable shared Internet access. Since most broadband router setup interfaces and functions are similar, these router configuration steps also apply to other broadband router products.
1. Broadband Router Setup
After the hardware connections are complete, we need a PC connected to one of the broadband router’s LAN ports to perform the specific configuration. Before setting it up, we should confirm that this machine has the TCP/IP network protocol installed. The author is using a Windows XP operating system; the configuration steps on other operating system platforms are basically the same. Let’s look at how to configure this PC.
Configuring the TCP/IP options on the setup PC: Right-click the “Network Neighborhood” icon on the desktop and click the “Properties” option. In the pop-up window, select “Local Area Connection,” right-click it, and choose the “Properties” option. Then, in the dialog box that appears, double-click the “Internet Protocol (TCP/IP) option.” In the new dialog box, select the “Use the following IP address” option, and now we can set the IP address for this PC. The factory default IP address for broadband routers is usually 192.168.0.1, so we need to set the configuration PC to be on the same network segment as the broadband router during configuration. Here, we will set this PC’s IP address to 192.168.0.254, the subnet mask to 255.255.255.0, and the default gateway to 192.168.0.1.
With the above settings, we can log into the router for specific configuration tasks. First, double-click the IE browser on the desktop and enter the IP address 192.168.0.1 into the address bar.
First, double-click the IE browser on the desktop and enter the IP address 192.168.0.1 into the address bar. After pressing Enter, we can see the router’s configuration interface. Because this is the first time configuration, no username verification is required by default. Some broadband routers do require a username and verification, such as D-Link products, where the default username is Admin and the default password is blank. If you encounter a product that requires username and password verification, you can refer to the product manual for the relevant username and password information.
Next, we click the “Setup Wizard” option, which will take us to the router’s configuration wizard interface. This page displays a welcome screen for the configuration wizard. We can directly click “Next” to proceed with the configuration. An Internet access option interface will then appear. In this interface, we can make a specific selection based on the broadband line we are using. Currently, the most common broadband access lines are ADSL, CABLE MODEM, and community broadband. For a CABLE MODEM line, we can select the first option, while for ADSL and community broadband lines, we can choose the second option. Here, let’s assume the user is using an ADSL line, so we select the second option and click “Next” to continue.
Next, we need to choose what login method to use. Generally, telecom operators use PPPoE dialing to manage users, so here we select the first option and click “Next.” After clicking “Next,” the system will prompt the user to fill in some information. PPPoE dialing requires a user verification process, and we need to enter the information provided by the telecom operator into the dialog box. Click “Next.” After filling in the necessary information, the router will ask you to choose the IP address type. Most users use an IP address automatically assigned by the telecom operator, so here we select the first option to complete this configuration.
Note: Here, we have introduced readers to automatic configuration using the broadband router’s setup wizard. Experienced users can also manually configure the broadband router according to their needs. It is recommended that users configuring the router manually should review its product manual in detail.
2. Setting Up PCs for Shared Internet Access via Broadband Router
After the broadband router setup steps above, the router is now capable of providing NAT translation functionality for the PCs that need to share the connection. However, our PCs still cannot access the Internet because some TCP/IP option settings need to be configured on the client machines before they can go online. In fact, users can also enable the broadband router’s DHCP function, which would allow PCs to automatically obtain IP addresses, default gateways, DNS, and other information without needing manual configuration. However, since enabling DHCP can significantly impact the broadband router’s performance, we recommend using this static IP address assignment method here to achieve better performance.
First, just like the machine we used to configure the broadband router earlier, we right-click on the “Local Area Connection” properties within “Network Neighborhood,” open the dialog box, and select the TCP/IP options. Under the TCP/IP options, choose “Internet Protocol (TCP/IP) options.” In the pop-up dialog box, enter the IP address, default gateway, and DNS options sequentially. In a local area network, our IP addresses generally use private Class C IP addresses. Here, we will type 192.168.0.x, where x should be different for each machine, such as 192.168.0.2, 192.168.0.3… The Windows XP operating system will automatically generate the subnet mask based on the IP address you entered, and users are advised not to modify it arbitrarily. One crucial thing to remember here is that our broadband router is generally set to the address 192.168.0.1, so our client machines cannot use this IP address; otherwise, it will cause IP address conflicts, resulting in all machines being unable to share the Internet connection.
After setting the PC’s IP address, we set the default gateway to the broadband router’s IP address, 192.168.0.1. When our PC accesses the Internet, it will send connection requests to the broadband router. Finally, we set the DNS server. This option varies depending on the region and the line provider. Here, we enter 202.100.96.68; users should configure this specifically based on the broadband line they have applied for.
Alright, after these settings, the PCs in the local network can share Internet access through the broadband router.
3. Broadband Router Setup Summary
After completing all the broadband router setup steps above, we can use the broadband router to share Internet access. There are many more advanced feature options in the broadband router, such as DHCP, security, etc. Readers can learn about the specific application methods for these options from the IT168 website and configure them appropriately according to their actual needs.
