Exploring wireless route advanced options to resolve IP address conflicts

This article describes in detail how to set advanced options for wireless routing and how to solve IP address conflicts, I believe that reading this article will help you.

Nowadays, many ordinary consumers only use a relatively small part of the functions to buy wireless routers, but simply use the wireless connection function of wireless routers to access the Internet or transmit data, I do not know much about some advanced functions provided by the wireless router itself. However, if you use these advanced features properly, it will increase your wireless Internet usage. Today, I will introduce you to the next simple advanced function option: DHCP server.

Let's first understand what a DHCP server is: the DHCP server is in a network using TCP/IP protocol. Each computer must have at least one IP address to connect and communicate with other computers. To facilitate unified planning and management of IP addresses in the network, DHCPDynamic Host Configure Protocol and Dynamic Host Configuration Protocol have emerged. This kind of network service facilitates the effective management of the Client IP addresses in the campus network, without the need to manually specify the IP addresses one by one.

IP address conflict

In some wireless networks, due to the large number of client laptops, we usually use the DHCP service provided by the wireless router to facilitate management of these machines) provides TCP/IP Parameter configurations, such as IP addresses, Gateway addresses, and DNS servers. However, if some computers in your wireless network must manually specify the TCP/IP parameter configuration, the dynamic IP Address Provided by the DHCP server and the manually specified static IP address will coexist, in this case, if you do not properly configure the parameters of the DHCP server in the wireless router, IP address conflict may occur.

For example, if you have 8 computers in your home and want to connect to the wireless router at the same time, but three of them have special needs, you can manually set static IP addresses, the IP address segment used is "192.168.1.10 -- 192.168.1.12". The other five computers obtain the IP address and other parameter information through the DHCP service of the wireless router. However, if the "address pool" parameter of the DHCP service in your wireless router is set improperly and contains the IP address segments used by the above three computers, an IP address conflict may occur. The cause of the conflict is very simple. For example, if computer A with the static IP Address "192.168.1.11" is not started, when A computer B in the wireless network requests an IP address from the DHCP server of the wireless router, the DHCP server finds that the IP address "192.168.1.11" is currently idle and is not used by any computer. Therefore, it is very likely that the IP address will be allocated to the computer B requesting the IP address. When computer A starts and goes online, it will find other computers using the IP address "192.168.1.11", so there will be IP address conflicts. In this case, the DHCP server parameter settings are incorrect.

Resolution of IP address conflicts

Knowing how IP address conflicts occur in wireless networks is easy to avoid. As long as you properly set the "address pool" parameter in the DHCP server. To avoid IP address conflicts, when configuring the "address pool" parameter of the DHCP server, you must exclude these IP address segments occupied by static IP addresses.

To facilitate consumers' understanding, I found a wireless router and found the DHCP server option on the WEB interface.) the computer using a static IP address occupies the IP address segment "192.168.1.10 -- 192.168.1.12, to avoid conflicts, this IP address segment must be excluded when the "address pool" parameter is set. The "address pool" parameter is set to "192.168.1.13 -- 192.168.1.60 ", this not only satisfies the needs of the remaining five computers, but also prevents IP address conflicts.
