I have lost internet protocol version 4 (TCP/IPV4). when I try to load helps to recover IPV4.

Thank you for reaching out to us. Windows 10 may have encountered a network configuration issue that caused this. For us to help you with this concern, kindly answer the following questions:

• How are you connected to the internet? Are you using a wired or wireless connection?
• What troubleshooting steps have you done so far?
• Have you tried installing a network driver from the manufacturer's website?
• What is the make and model of your network driver?

Meanwhile, we suggest that you perform these steps to reset your connection:

Step #1: Windows 10 has a capability to setup a new network connection that makes your device connected online. There are two types of connection, static and dynamic. For best results, we recommend establishing an automatic IP address configuration.

To do this, you will need to enable the Dynamic Host Configuration Protocol (DHCP) to your computer. This protocol automatically assigns IP addresses that are unique from the network.

In addition, you need to make sure that you are not using a static IP address. Manual setting of IP address causes conflicts throughout the network.Visit this article: Establish Dynamic IP or DHCP: Change TCP/IP settings to know how to enable or establish this type of connection.

Step #2: Perform an Internet connection reset via Command Prompt. To reset your Internet connection, follow the steps below:

1. Press Windows + R to open the Run window.
2. Type cmd, then press Enter.
3. On the Command Prompt window, type the following commands, then press Enter after typing each commands below:

netsh int ip reset resettcpip.txt

netsh winhttp reset proxy

netsh int ip reset

ipconfig /release

ipconfig /renew

ipconfig /flushdns

netsh winsock reset 4. Restart your PC to complete the process.

Step #3: We also suggest that you restart both your "Network Attached Storage Device (NAS)" and computer. Wait for 15-30 seconds then turn it on again. Visit this link: Fix network connection issues in Windows 10 for more troubleshooting alternatives for your Internet connection.

Step #4: Ping Microsoft server then tell us the result through a screenshot.

1. Press Windows key + R to open the run window.
2. Type cmd, then press Enter.
3. On the Command Prompt window, type ping www.microsoft.com, then press Enter.

• If you receive 4 replies, your connection with the site is working properly.

• If you got a request time out, your Internet connection has issues.

Step #5: Disable all other anti-virus programs and enable Windows Defender.

We'll be waiting for your reply.

Hi Karan,

This might be caused by changes made after the update. If the above steps did not work, let's try another workaround. If it happened after the update, try rolling the driver back. Follow the steps below:

1. Open Device Manager.
2. Look for Network adapters and click it to expand.
3. Select the driver for your dongle then right-click on it and select Properties.
4. Under Driver tab, click the Roll Back Driver button to roll back the driver.

If the issue still persists, try doing a system restore to go back in time before the issue occurred. Refer to this article and go to the Restore from a system restore point section to know how to do a system restore.

We're just a post away if you need further help.

thank you for your feedback
