First, understand the wireless router debugging and installation environment

This is a comprehensive article about debugging. In wireless router debugging, the network environment, hardware connection, and parameter configuration are strictly required. Let's see if these prerequisites are met. Among all the wireless network solutions described above, the most widely used, simple to construct, and most convenient to manage is the networking mode of the wireless router + wireless network card. Therefore, a detailed understanding of the configuration and use of this type of networking mode is a key point to step into the wireless Hall. Let's take a look at the detailed knowledge of this type of mode in installation and debugging.

I. Network Environment

It integrates wired routing and wireless access functions. Like a wired router, it also provides four LAN ports. Therefore, the network debugged by a wireless router has the greatest adaptability. You can use a network cable for Wired connection or use a wireless network card to connect to other wireless terminals. Generally, a wireless router and several wireless network adapters can be used to build a complete wireless network environment. The entire wireless network environment can be described as ADSLModem + wireless router + wireless network adapter.

Ii. Hardware connection

The ADSL line is connected to ADSLModem, and then the WAN port of the wired router is connected to the WAN port of the ADSLModem. If there is a wired router in the original network, any LAN port of the wireless router can be connected to any LAN of the wired router.

Tip: if you do not use the routing function, the RJ45 line of the ADSL adapter cannot connect to the WAN port, you should connect to the lanport, otherwise it will always be offline. Through such a connection, the remaining LAN ports of the wired router can be connected to the fixed desktop, while the wireless router debugging can be used as a pure AP for the mobile shared Internet access of the laptop. After that, make sure that the power supply of the ADSL adapter and wireless router is fully enabled, the power indicator light, and the indicator light at the connection port are green ). Next, we will install a wireless network card for other computers. This has been introduced to readers in the previous article "installation and debugging of point-to-point wireless networks", which will not be detailed here. After the hardware connection is complete, configure the specific device.

Iii. parameter configuration

1. Open the ADSLModem route.

Because it is necessary to achieve wireless Internet sharing among multiple computers, routing is required. Most ADSLModem now comes with the routing function, you only need to enable it. Different ADSLModem enable the routing process is different, but most of them follow these wireless router debugging. The ADSLModem mentioned here is a product of Alcatel ):

Step 1: Enter the default IP address of the product in the browser, and enter the default account to enter the default IP address of the product on the ADSLModem management interface. The default IP address and default Logon account can be found in the product manual ).

Step 2: Find options like "general settings" or "quick Settings". There are a lot of things to do here. First, select the connection protocol. Currently, ADSL uses the "virtual dialing" method to access the Internet, and it corresponds to PPPoE.

Step 3: The next important configuration item is "VPI/VCI" virtual path identifier/virtual channel identifier ). Generally, the value of VPI cannot exceed 8, and the value of VCI cannot exceed 35. If you are not clear, you can ask the local telecom or ISP supplier. The value of VPI/VCI in the region where the author is located is 8/35. Because ADSLModem enables the routing function, it is equivalent to a gateway computer, which is used for dial-up connections, you should set your own ADSL account and password in the Modem attribute.

2. Configure the wireless router for debugging.

Step 1: log on to the wireless router. Select a computer that is wired to the wireless router, enter the default IP address of the wireless router in the browser, which is generally 192.168.1.1, which can be found in the product manual), and enter the account name and password of the router administrator, log on to the wireless router management interface.

Step 2: configure the SSID number. After entering the management interface, click the "Wireless Settings" option on the left of the main interface to open the settings interface. Generally, you only need to set the wireless router here. The "SSID" can be set at will, for example, "mynet" in this example, and then select the transmission rate in the "Mode" column according to the specifications. In order to make the wireless network more secure, we recommend that you remove the "allow SSID broadcast" check box. After that, you can click "save. Tip: To further ensure wireless network security, you can also select the Enable Firewall option under the "Security Settings" option. What is wireless router debugging?

3. Set the wireless network card.

Step 1: Open the wireless network card configuration program and go to the user configuration page. On the "General" tab, enter the same SSID value as the wireless router "mynet" in the "Network ID" column ".

Step 2: switch to the "advanced" tab. If you select the "auto-select" Mode on the vro, you can set the Authentication mode here. If you want to change the Authentication mode, you can keep the default mode. Tip: For the security settings of the wireless network card, you can configure the "Security" tab shown in the SSID number. With the preceding simple settings, you can connect the wireless network card to the wireless router.

Iv. Summary

Through the above steps, as long as the ADSLModem and the wireless router are powered on, all the computers in the network can communicate with each other and share the internet. In fact, the configuration of the wireless network is not much different from that of the wired network. Generally, a wireless router can connect more than 40 wireless nodes. Regardless of the wired or wireless network, the configuration process is similar, as long as you understand the parameters that should be set, and then find the corresponding option location in the device. After the above explanation, I have basically understood what is wireless router debugging.
