How to solve wireless IP conflicts

Network has become an indispensable tool in our life, and users with notebooks often use wireless networks, but wireless networks sometimes have problems that will bother us. Wireless IP conflicts are common failures we encounter when using wireless networks.

So what is the cause of this? How should it be solved? Let's take a look at the details. In some wireless networks, due to the large number of clients, in order to facilitate the management of these machines, many administrators use the DHCP service provided by the wireless router to provide TCP/IP parameter configuration for the client, such as IP address, gateway address and DNS server, etc. However, if some computers in your wireless network must manually specify the TCP/IP parameter configuration, then the dynamic IP address provided by the DHCP server and the manually specified static IP address coexist. If you do not properly configure the parameters of the DHCP server in the wireless router, It can easily cause IP address conflicts.

How does wireless IP conflict occur?

As a wireless network managed by the xp system download station, there are 50 computers, 5 of which have manual settings for static IP addresses due to special needs. The way to use the IP address segment is "192.168.1.10~192.168.1.14", and the other 45 computers obtain the IP address and other parameters through the DHCP service of the wireless router. However, if the parameter setting of the DHCP service's "address pool" in your wireless router is unreasonable and contains the IP address segment used by the above five computers, IP address conflict may occur.

The reason for the IP address conflict is very simple. For example, if the computer A using the static IP address “192.168.1.11” is not turned on, when a computer B in the wireless network requests IP from the DHCP server of the wireless router. At the address, the DHCP server finds that "192.168.1.11" is currently idle. Without any computer, it is very likely that this IP address will be assigned to the computer B that applied for the IP address. When the computer A is powered on and online, it will be found that other computers use the IP address of “192.168.1.11”, and an IP address conflict will occur.

Solving wireless IP conflicts requires reasonable setting of DHCP parameters

Knowing how wireless network IP address conflicts are generated, it is very simple to prevent this from happening, as long as you set up a DHCP server properly. In the “Address Pool” parameter. You need to know clearly which IP address segments are occupied by computers with static IP addresses. To avoid IP address conflicts, you must exclude the static IP addresses when configuring the DHCP server's "Address Pool" parameter. These address segments.

In order to solve the wireless IP conflict problem more intuitively, here is the example of the author's wireless network (as shown in the figure). The computer with static IP address is occupied. & ldquo; 192.168.1.10~192.168.1.14” this IP address segment, so the IP address segment must be excluded when setting the "Address Pool" parameter to prevent conflicts, such as the author will "Address Pool" parameter Set to “192.168.1.15~192.168.1.60”, which satisfies the needs of 45 dynamic IP address clients and prevents IP address conflicts.

There is a reason for wireless IP conflicts, but most users don't know the truth. Now we know the reason through the problem and know how to solve it. I hope I can solve it myself when I encounter similar problems next time.
