If you’ve previously encountered a networking issue that says Ethernet doesn’t have a valid IP configuration, then something is wrong with your Network Interface Card.

The NIC is connected to your router or modem via the Ethernet cable. The problem arises if it fails to obtain a valid IP address.

A valid IP address is necessary for a computer to communicate with the router and operate in the web. Once a certain router or NIC becomes faulty or in case of incorrect IP address designation, an error occurs.

The following solutions provide a fix to various problems related to IP address configuration. Keep in mind to follow the following steps in exact order.

Why am I getting No valid IP configuration when using Ethernet connection?
