If Windows 7 is not connected to the Internet, the default gateway address 0.0.0.0 appears when ipconfig is queried.

Windows 7 computers do not go to the network. When ipconfig is queried, the default gateway will encounter the 0.0.0.0 problem. Today, a colleague's laptop is on a business trip and suddenly cannot go to the network, I checked that the IP address settings in the network connection window are correct, but the webpage cannot be opened. The Ping command can be used to ping the gateway, but the ping route egress and dns cannot be connected. This is indeed strange, and the ping command can also be used to ping the computer connected to the same switch, the computer on the same vswitch can access the Internet normally. It seems that the configuration of this notebook is wrong. You can use ipconfig to view the network configuration of www.2cto.com and find that all the other settings are correct. However, the default gateway has an 0.0.0.0 record, and the network connection cannot be restored after it is disabled. I found someone on the Internet to change the Registry. Open the registry and find

HKLM/System/CurrentControlSet/Services/Tcpip/Parameters/Interfaces/xxxxx Delete the 0.0.0.0 data row at the top of the defagateway gateway key value in the corresponding Nic. Xxxx is a long string of letters, which indicates the network card in the system. It is not easy to identify. You can determine the local connection based on the IP content in the right window. The network connection is restarted and the Internet access is normal. Author upi2u
