Windows 10: Ethernet connection to modem cannot get an IP address assigned to my PC

I have my modem right next to my PC so i tried connecting an ethernet cable from the LAN port directly to my PC. Even though connection works, no internet is getting through and the troubleshooter says "Ethernet dosen't have a valid IP configuration". connected the ethernet cable to my laptop and got the same end result, so it's not a hardware issue

:)

 

Windows 10 as WiFi Hotspot not assigning IP addresses


I haven't tried, but you could connect your PC to the internet by cable and create an ad hoc wireless connection between the PC and the other device to get internet. Right-click on the network icon and select Network and Sharing Center. Then click on Change adapter settings. This shows all your adapters and connections. Right-click on the Ethernet connection and select Properties, then click the Sharing tab. Check the box to Allow sharing the connection and select your wireless connection from the list. I am not sure if it will work with automatic settings though, you may have to manually assign an IP address to the wireless connection. Then manually assign an IP address at the other device and set the Default gateway to the IP address of the PC's wireless connection. Also you have to create a new ad hoc connection and connect to that from the other device. I don't currently have a Wi-Fi card, so I cannot see the steps to guide you.

 

No IP address for Ethernet connection

Hello

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.

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
