Since you are here which means you are looking for a fix. Luckily the fix is just some setting twitches that you can do to resolve the issue.

Your computer has its dynamic configuration enabled by default. Therefore, there is no need for users to configure settings manually in order to connect the DHCP server.

But sometimes DHCP didn’t get the valid IP address from the Network Interface Card(NIC) due to which an error “Ethernet doesn’t have a valid IP Configuration” pops up.

If you are reading this article then it means that you are here to seek a solution and not just to know the reason behind the error. 

So, we are going to lay the solution to this problem and methods to fix “Ethernet doesn’t have a valid IP configuration” error.

Step 4: Now under the General tab, make sure “Obtain an IP address automatically” is selected instead of the “Use the following address”.

Note:- With obtaining an IP address automatically your system is going to check and get the IP-address for your DHCP server.

DHCP Stands for Dynamic host configuration protocol that is used to assign the IP-address to multiple connected PCs or any network devices. If you are using your laptop or PC in-home network then your modem or router is acting as a DHCP server for you.

  • In Windows dynamic configuration enabled by default
  • It can be due to many different methods like malfunction of EthernetCable, or disabled Network Adapter, enabled fast startup, disabled IPv6, Malufuntioning of Router Modern
  • It can be solved by correcting the above faults or by the command prompt(netsh winsock reset, netsh int IP reset), Reinstalling IP/TCP and Network adapter.
