Note: You can go to another computer to see what their IP address class is by using the ipconfig /all command

And the last number of that sequence is the IP address of your computer. This number must not be coincident with other computers on the LAN because there will be a dispute. One of the two machines will lose the network, or The connection will lose both. lost.

Here I will try to set it as 150 , you can get numbers between 1 and 254 as long as it is different from the modem’s address and the IP of another machine. If one doesn’t work, you can try another one.

=> After I finish, I will have a full sequence of numbers that is 192.168.1.150

Subnet mask: Let the machine fill in automatically.

The Default Gateway part is the gateway for us to connect to the outside or connect via the internet, so please enter the correct IP of the modem.

Usually, only one of the two ranges is used, 192.168.1.1 and 192.168.0.1. My modem uses the range 192.168.1.1.


=> Click OK for the computer to receive the new IP.

Note: If it still doesn’t work, try another number sequence, for example, 192.168.1.151…
