It is quite irksome when you find an error in accessing your internet when you have to send an important e-mail, or the situation might be even worse.

But, don’t worry, your saviour is here, we will show you a step to step guide to fix the “Ethernet’s Invalid IP Config” error. 

What Is An Internet Protocol (IP)

Internet Protocol

An IP is an address that establishes communication over one to another device to access the internet via a network that is based on many such IP addresses. So, basically, an IP is the address or identity of your current device over an internet network.

Just like the address of your home or your workplace, the IP of your device has a uniquely specified address that cannot be specified or allocated by other users.

Types of IP Addresses: There are several kinds of IP addresses, such as Private IP, Public IP, Static IP, and Dynamic IP. Also, they can be classified further into IPv4 or IPv6 types.

Reason for Occurring Error “Ethernet doesn’t have a valid IP configuration”

The invalid Ethernet IP configuration error indicates that your operating system (Windows 10 in this case) is not receiving the necessary IP configuration from the Dynamic Host Configuration Protocol (DHCP) as your ethernet connection no longer assigns a valid IP address over it.

Now understand, what is DHCP? The DHCP is a network protocol arrangement that enables a server to assign an IP to your device for a specific kind of network automatically.

If you receive an “Ethernet doesn’t have a valid IP Configuration” error, it means your device could not be allocated a valid IP address and is not able to communicate with your desired network, and that is why you would not be able to connect your device with the internet.
