The IP (Internet Protocol) addresses are an integral part of the Internet that normal users may not even know exists. An IP address is presented as a string of numbers that acts as a specific device's identity within the broader network. A good analogy is to imagine an IP address similar to a unique home or work address that helps others identify this specific location. One common error that users oftentimes experience is the 'Ethernet doesn't have a valid IP configuration' error.
The meaning of these seemingly cryptic words is that the user's ethernet connection no longer has a valid IP configuration, and the Windows operations system cannot receive the required IP address. The most common motives for this error are problems with the network adapter drivers installed on the system as well as an incorrect network configuration.
Usually, the first solution the affected users should try is to simply restart their computer as well as their router and modem devices. If the error persists after the restart of the devices, users have to move on to more technical options.
Clearing the network cache might fix the problem. Open Command Prompt and type in the following three commands:
Hit enter, restart the computer system, see if the 'Ethernet doesn't have a valid IP configuration' error is still there.
In the case that clearing the network cache failed to address the issues, users should attempt to uninstall manually and then reinstall their network adapter drivers. To start, right-click the Start button and select 'Device Manager.' In the list of devices that appear, go to 'Network adapters,' expand it and locate the network device. Right-click it and choose 'Uninstall.' If the option 'Delete the driver software for this device' is presented, select it. The computer system will have to be restarted for the changes to take effect. Windows should install the now missing drivers by itself, but if that is not the case, open Device Manager again, right-click your computer name and select 'Scan for hardware changes.' This should force Windows to detect the missing drivers and then install them.
Another potential solution is to visit the official website of the manufacturer of your motherboard and look for their specific ethernet drivers. Download and install the drivers could stop the 'Ethernet doesn't have a valid IP configuration' error from appearing.
