Ethernet doesnt have a valid ip configuration

Every computer or device that you can use to surf the web has an IP address assigned to it. This IP address allows the device to be identified on the internet or within a local area network.

But sometimes, you might get an error that says your Ethernet doesn't have a valid IP configuration.

This error is caused by various problems with the network interface card (NIC) - the hardware that connects a computer to a network. It can also happen because of faulty drivers and an improperly configured router or modem.

In this guide, I will show you four ways you can fix the problem of your Ethernet not having a valid IP configuration.
