IP address is a unique identifying number which is associated with computers on the internet or a local network.
The IP address makes it possible for computers to send and receive information between each other.
A Network Interface Card (NIC) is a hardware component that enables your computer to be connected over a network. It works by using either a wired or wireless connection.
To check your NIC, you need to check whether it’s in a state of “unrecoverable state.
What DHCP enables computers to get IP addresses automatically is called Dynamic Host Configuration Protocol (DHCP).
The error Ethernet doesn’t have a valid IP configuration indicates that your computer doesn’t have the proper settings in place to create a working connection.
What Causes Ethernet doesn’t have a valid IP configuration?
It’s fairly common for a NIC to fail, and a faulty NIC will result in the Ethernet cable doesn’t have a valid IP configuration error message.
Unused ports on your network router can sometimes result in a message like “The IP Address Is In Use”. This means the message is not coming from your internet service provider, and may be related to an error on your own network.
The error message may be due to incorrectly assigned IP addresses.
Some fixes to fix the “Ethernet doesn’t have a valid configuration” error.
Let’s look at them one step at a time.
Reboot your Computer and Router
Sometimes all it takes to fix something that seems to be too complicated is to do what looks simple.
Shut down and restart your computer, and that might do the trick.
In previous versions of Windows, the issue could be caused by having the Fast Startup feature enabled. In those earlier versions of Windows, disabling Fast Startup can prevent that issue from occurring.
To disable Fast Startup:
Click on the Windows button and press the X key at the same time >> Go to Power Options >> Click on the “Additional Power Settings” tab >> Click on the “Choose what the power button does” tab >> Under “Advanced Power Options”, uncheck the “Turn on fast startup” checkbox.
Turn off your router or modem for 10 minutes. It will come back online faster and be more reliable.
Double-check your Ethernet cable now to see if it gets a valid IP configuration.
Check your Network Adapter Settings
By default, your router assigns IP addresses automatically, even though you may want to assign them manually.
In order to prevent the “Ethernet doesn’t have a valid IP configuration” error, first try to change it to automatic, and then make sure that you set the correct network settings in manual mode.
Press the Windows and R keys together >> Type ncpa.cpl in the search field and press Enter >> Right-click on Ethernet and choose Properties >> Next, select “Internet Protocol Version 4 (TCP/IPv4.” and click Properties >> Make sure the “Obtain an IP Address Automatically” and “Obtain DNS Server Address Automatically” settings are selected
You will have to set the IP address manually:
Go back to the connection settings, select “Internet Protocol Version 4 (TCP/IPv4.” >> Properties >> Select “Use the following IP address” and “Use the following DNS server addresses” settings >> Enter the IP address details like IP address, default getaway and subnet mask >> Click on OK.
Reset TCP/IP and Network Adapter using Command Prompt
Press and hold Windows and X keys >> Click on “Command Prompt (Admin) or Windows PowerShell (Admin) depending on which your computer has >> Type “net stop winsock” and click Enter to shut down the Winsock
Reset TCP/IP by typing “netsh hint IP reset” and then type “netsh int ipv4 reset” and finally, type “netsh int ipv6 reset”.
Uninstall/Reinstall your Network Adapter
If the error still hasn’t been corrected, then you should try unplugging and replugging your network adapter.
Press and hold the Windows key and R keys (press and release) together. Type “C:\ProgramData\Microsoft\Windows\CurrentVersion\Run” in the field and click OK. Click OK again. The registry editor will open.
Reinstall the network adapter by going to your device manager.
There are two methods that you should use to configure your Ethernet interface. One works and one does not.
