3. Change the ipv4 in the host wireless network card properties, ip: 192.168.0.1 Subnet mask: 255.255.255.0 Default Gateway: 192.168.0.1 Preferred DNS Server: 192.168.0.1 Backup does not fill Click OK

4. The extension also changes the ipv4 in the wireless network card properties. The difference from the host is IP 192.168. 0.X (X can be any number other than 1 from 0 to 255), other values ​​are set to be consistent with the host
