What are the possible solutions to solve this error?
Solution 1: Restart Your PC, Modem, and Router
Sometimes, the issue can be fixed by simply restarting the affected hardware. You need to save all your work before restarting your PC.
- Click on the Windows icon and open the Start menu.
- Click on the Settings icon and select the Power icon. Proceed and select the Restart option. Your PC will shut down and restart by itself.

Solution 2: Disable the Fast Startup Feature
You can try solving this error by disabling the Fast Startup feature. This feature comes by default for the majority of Windows 10. Its role is to allow the PC to recover quickly from shut down or hibernation, allowing it to boot up quickly.
To turn off this feature, you should follow these steps:

- Then select Save changes icon and restart your PC. Once you’ve restarted your PC, you should confirm if the problem is resolved or not.
Solution 3: Configure the Network Adapter Settings
You need to know that a router is automatically designated to each connected device by an IP address. However, you can configure this setting by assigning it one static IP address.
To configure your network adapter settings, you should do the following:
- Hit the Windows + R key to bring up the Run feature. Then enter ncpa.cpl text and click Ok. What this will do is open up the Network Connections window.
- Proceed and click on the Ethernet adapter settings and proceed to choose the Properties option.
- Once you get to the Ethernet properties dialogue box, check out Internet protocol version 4 (TCP/IPv4) and double-click on it.
- You will be redirected to the properties of the Internet protocol version 4 (TCP/IPv4). Once you get there, you will have the following options that you will be required to enable: Obtain an IP address automatically and Obtain DNS server address automatically.
- If after doing all that, the error is still popping up, you can proceed and set your DNS and IP address manually. To do so, you need to follow the previous steps and on the Internet Protocol Version 4 (TCP/IPv4) Properties, select and edit these options.
- Try using the following IP address and fill in the details with the following numbers:
- Default gateway: 192.168.1.1
- Subnet mask: 255.255.255.0
- IP address: 192.168.1.15
- Try using the following IP address and fill in the details with the following numbers:
- The next thing you need to do is use the following DNS server address and then fill in the details with the following numbers:
- Alternate DNS Server: 188.8.131.52
- Preferred DNS Server: 184.108.40.206
After completing that, click on OK to save the changes you have made. You need to know that these are Google’s DNS settings.
Solution 4: Reset TCP/IP
For this method, you will be required to use the Command Prompt option as well as the netsh command. Doing this enables you to modify or display the network configuration settings of your PC.
To reset the TCP/IP, you need to do the following:
- Begin by typing in the Command Prompt under the Search icon. You can do that by hitting the Windows + S key.
- Proceed and right-click on the Run as Administrator option to open up the elevated command prompt. You can also right-click on the Command Prompt icon and then select Run as Administrator. You need to click OK when it asks for permission.

- Once you are on the elevated command prompt, type the following commands and then hit the enter button key to execute them properly.
- netsh winsock
- Reset netch int IP reset
- Once you run the first command, you will receive a message requiring you to restart your PC. Ignore it and proceed to run the second command.
- Once both of these commands have run successfully, consider restarting the PC and check if the error has been fixed.
Solution 5: Clear the Network Cache
For this method, you will use the ipconfig command in the elevated command prompt. What this command does is that it displays the current configuration that has been installed on the IP stack. The advantage of using it is that it allows you to reset all the contents of the DNS client resolver cache as well as renew the DHCP configuration.
- First, hit the Windows + S key to prompt the Search icon.
- Proceed and click on Run as Administrator to open up the elevated command prompt option. Alternatively, you can right-click on the Command Prompt icon and proceed to click on Run as Administrator. If it asks for permission, click OK and proceed.

- To update the drivers, you can follow the steps discussed earlier but rather than select the Uninstall option, you will choose the update drivers option.
After doing this, you will be prompted to a window. It will ask if you are searching for the updated driver software automatically or manually. By choosing the first option, your PC will go for the latest driver software for the device.
If you choose the second option, you will be compelled to locate and install the drivers manually. That option requires you to have already downloaded the drivers. If by any chance the first option fails to solve the issue, you should go ahead and download the latest network adapter drivers from the manufacturer’s website.
Solution 7: Disable Microsoft Kernel Debug Network Adapter
