What should I do if the IP address conflicts with other systems on the network?

The reason why IP addresses conflict with other systems on the network is that they are all connected to the Internet through a router, so IP conflicts are inevitable. This results in the inability to access the Internet.

To solve this problem, you can follow the following steps.

1. Set it to be automatically obtained by DHCP

If the computer is in a LAN and the network card IP address is automatically assigned by the LAN server, you can click the "Start" button and select " "Command Prompt" in "Attachments", enter "Ipconfig /renew" in the command line state to let the system release the current IP address and obtain a new one.

If the computer’s IP address is a fixed IP address, you can set another one.

2. Modify the local IP address

In the "This connection uses the following components" list box in the "General" tab of the computer, select " Internet Protocol (TCP/IP)" and click the "Properties" button. In the "Internet Protocol (TCP/IP) Properties" dialog box that appears, select the "Use the following IP address" radio button in the "General" tab, and then fill in the required text box below.
