Windows 10: Windows 10 20H2 Ethernet no IP Address

I just installed Windows 10 Home 20H2 and my hard wired ethernet connection no longer connects to the internet, but the WiFi connection does work. I have run the Troubleshooter on the Ethernet connection and it says that it does not have an IP address. Uninstalling the Ethernet connection via the Device Manager and reinstalling it does not fix the issue. I tried to using a fixed IP address and that did not fix the issue. I restarted my router and that did not affect the issue. When I run the Troubleshooter I can see that the port is reset, the link is lost, the link is established, then some traffic occurs then stops. I know my router is functioning, since I can post this message using the WiFi connection. Other computers on the local network can connect to the internet with the same router and have no issues. Windows Update says that all updates are applied and no new ones are available.


I searched and found a "fix", to disable the connection, restart and then re-enable the connection. That worked for about 10 minutes but then the same issue came back. I tried this "fix" again and this time it did not resolve the issue.


My next step is to try to go back to an earlier restore point to see if this resolves the issue. Several users have said that this works, but when 20H2 is reinstalled this issue returns.


Any suggestions? I will wait on the restore point till I get a response from here on another possible fix.

No IP address for Ethernet connection

Hello

I'm Peter F independent Advisor

Solution 1 – Reboot the system

Ethernet doesn’t have a valid IP configuration error can be caused by Fast Startup feature. To fix this error, you need to follow these steps to disable Fast Startup:

Press Windows Key + S and enter control panel. Now select Control Panel from the list of results.

Ethernet doesn't have a valid IP configuration TP Link

Select the Power Options from Control Panel.

Ethernet doesn't have a valid IP configuration TP Netgear

In the left pane, click on Choose what the power button does.

Ethernet doesn't have a valid IP configuration Powerline

Select Change settings that are currently unavailable.

Ethernet doesn't have a valid IP configuration router

Uncheck the box beside Turn on fast startup (recommended) near the bottom of the window to turn off Fast Startup.

Select Save changes.

Ethernet doesn't have a valid IP query

Reboot your computer.

Solution 2 – Check the Network Adapter Settings

The router works to designate the IP address automatically. This is the default setting, though you can still choose to assign a specific IP address. In that case, you ought to set the IP address to automatic first and check the Internet Properties for the
correct settings once it is connected. Follow the instructions below:

Hold the Windows Key and press R.

Enter ncpa.cpl in the input field and click OK.

Ethernet doesn't have a valid IP configuration Unidentified Network

Right click your Network Adapter in the Network Connections window and select Properties.

Ethernet doesn't have a valid connection

From the Ethernet Properties window, select Internet Protocol Version 4 (TCP/IPv4) and click on Properties.

Ethernet doesn't have a valid config

You will then see the Internet Protocol Version 4 (TCP/IPv4) Properties window. Enable the following options:

Obtain an IP Address Automatically

Obtain DNS Server Address Automatically

If obtaining the IP address and DNS automatically doesn’t fix the problem, you might want to consider setting both your IP address and DNS manually. To do that, follow these steps:

Open your connection properties, select Internet Protocol Version 4 (TCP/IPv4) and click on Properties.

Now select Use the following IP address and Use the following DNS server addresses. Fill in the data like on the screenshot below. After you’re done, click OK to save changes. To see the necessary information such as Default gateway and Subnet mask, you can
just check connection properties on any other device that can connect successfully to your network.

Ethernet doesn't have a valid IP address

Keep in mind that we changed our DNS to Google’s DNS in our solutions. According to users, it’s not mandatory to change both IP address and DNS, but if setting the IP address manually doesn’t help, be sure to change your DNS as well.

Solution 3 – Restart the router and check Ethernet cable

After performing the steps above, turn off your router or modem and switch it back on after five minutes. Now check if your PC has the valid IP configuration. If it still does not work, connect your router to your PC using a different Ethernet cable.

Otherwise, you may need to use a different router. If connecting to other routers won’t solve the problem, then there is an issue with your network card. Perform a factory restore to your network card, and if it does not help, replace it.

Solution 4 – Reinstall your Network Adapter

After completing the steps above, you must uninstall and reinstall your network adapter. Here is how:

Hold the Windows Key and press R.

Type hdwwiz.cpl in the input field and click OK.

Ethernet doesn't work

Expand the Network Adapters, right click on your Ethernet card, and choose Uninstall device.

Ethernet doesn't work on laptop

When the confirmation dialog appears, click on Uninstall.

Ethernet doesn't have IP configuration

Reinstall your network adapter using the driver accompanying the hardware.

If reinstalling the Ethernet card does not solve the problem, you should reinstall the network interface card using the latest version of the driver from the manufacturer’s portal.

Solution 5 – Use Command Prompt

If you can’t access Internet due to Ethernet doesn’t have a valid IP configuration error message, you might be able to solve the problem by using Command Prompt. According to users, you can solve this problem simply by running a couple of commands. To do that,
follow these steps:

Press Windows Key + X and choose Command Prompt (Admin) from the menu. If Command Prompt isn’t available, feel free to use PowerShell (Admin) instead.

Ethernet doesn't connect to Internet

When Command Prompt opens, enter the following commands:

netsh winsock reset

netsh int IP reset

After running these commands, you just have to restart your PC in order to apply the changes. Once your PC restarts, the problem should be resolved and you’ll be able to access the Internet without any issues.

I hope it helps

Ethernet Can't Obtain an IP Address from My Router

I really appreciate everyone's ideas!

I'm working through the suggestions, and here's an update:

I removed my Kaspersky software using Kaspersky's own uninstaller (kavremover.) This did not solve the problem, unfortunately.

Next step: Restoring my router to default settings.

- - - Updated - - -

I performed two final steps:

I booted my computer from a live Linux distro; Linux detected my Ethernet controller but could not obtain an IP address for it from DHCP (demonstrating that the problem is not caused by Windows.)

I reset my modem to factory defaults - no help.

Therefore, it seems very clear to me that my problem - I am unable to obtain an IP address for an Ethernet connection - can only be caused by the router hardware. My router is 7 years old, and nothing lasts forever ... I accept that. Still, it does seem mysterious to me. My router consists entirely of electrical components - there's nothing to wear out or break. As long as I don't abuse it, it should probably last forever and the only reason I would have to replace it is because newer equipment is so much better.

My final step was to contact the router manufacturer (ASUS) who assigned me a case number. I can't imagine what incentive they have to assist me with a 7-year old router, but I'll give it a shot.
