If the "No valid IP configuration" error occurs in the local connection, it means that your computer cannot obtain a valid IP address. This may result in the inability to connect to the network or prevent normal network communication. Here are some common ways to fix this problem:

1. Restart your network device: First try restarting your router, switch, or modem. Sometimes a temporary failure of the equipment may cause IP configuration problems. Wait for the device to restart and check whether a valid IP address can be obtained.

2. Obtain an IP address automatically: Make sure your computer is set to obtain an IP address automatically. Open Control Panel, go to "Network and Internet" and then select "Network and Sharing Center". Click "Change Adapter Settings", find the local area connection, right-click and select "Properties". Find "Internet Protocol Version 4 (TCP/IPv4)" in the properties window and double-click to open it. Make sure "Get IP address automatically" and "Get DNS server address automatically" are selected, save the changes and try to reconnect to the network.

3. Disable and re-enable Local Area Connection: Find Local Area Connection in "Network and Sharing Center", right-click and select "Disable", then right-click again and select "Enable". This will reinitialize the network connection and attempt to reacquire an IP address.

4. Refresh IP configuration: Open the command prompt (run as administrator), enter the command "ipconfig /release", and then press the Enter key. Wait for the command to be executed, then enter the command "ipconfig /renew" and press the Enter key. This will release the current IP configuration and try to obtain a new IP address.

5. Check network cables and physical connections: Make sure your network cables are properly connected to your computer and network devices (such as routers). Check if the cable is damaged or loose and try to replace the cable.

6. Reset the network adapter: Open the command prompt (run as administrator), enter the command "netsh int ip reset" and press the Enter key. This will reset the network adapter settings to default and may resolve IP configuration issues.

If the above method still does not solve the problem, there may be other network failures or configuration errors. In this case, it is recommended to contact your network administrator or technical support for further assistance.
