Disconnect the network first to prevent any conflict with the drivers downloaded from windows update

On Windows 11, Microsoft proactively releases updates to patch bugs, improve security and performance, and occasionally add new features. However, sometimes, system updates can also cause unwanted problems, and many times are connectivity issues.

For example, a lot of times, updates can make speeds and connections unreliable, especially with wireless adapters. Also, they can break connectivity entirely to the network and internet, cause network driver problems, and more.

If you cannot connect to the internet after installing a system update, Windows 11 offers several methods to resolve the issue and get back online quickly.

This guide will walk you through the steps to fix network issues after installing a Windows 11 update. 

How to fix network problems after installing update

If the device was recently updated and the network connection breaks, you can try these basic troubleshooting steps to resolve the issue. If the problem persists, continue with the more advanced instructions outlined below.

Reboot device

Sometimes, you can fix most problems by restarting the computer since this process clears the data in memory and restarts all the applications and system services.

To reboot a Windows 11 computer, use these steps:

1. Open Start.
2. Click the Power option.
3. Select the Restart option.

Once you complete the steps, open the web browser and load at least two or three websites to confirm the internet is working.

If only one of the sites isn’t opening, it could be a problem with the website or the page and not the internet connection.

Network connection test

If the restart didn’t solve the issue, you want to check whether the problem lies with the connection between the computer and the home router.

To check the network connectivity on Windows 11, use these steps:

1. Open Start.
2. Search for Command Prompt and click the top result to open the console.
3. Type the following command to find out the IP address of the router and press Enter: ipconfig

1. Confirm the «Default Gateway» address that should be the address of the local router. 

• Quick tip: Usually, home routers use the 192.169.1.1 or 192.168.2.1 address. 

1. Type the following command to determine whether the router is reachable and press Enter: ping ROUTER-IP 

This example tests the connection between the computer to the router with the 192.168.1.1 address: ping 192.168.1.1 In the command, remember to change the 192.168.1.1 for the router’s IP address. 

• Quick tip: You can also use the ping 127.0.0.1 command to test whether the networking stack is installed correctly.

1. Confirm successful replies without packet loss in the output.

After you complete the steps, if you see «4» successful replies in «Packets,» the connection between the computer and router is working. 

If this is the case, the problem could be something happening with your internet provider. However, if you can still access the internet from another device in the same network, it could be another problem with the computer.

Turn on wireless connection

If you have a laptop and there isn’t a connection to the internet, the wireless adapter may be disabled.

To enable the Wi-Fi adapter on Windows 11, use these steps:

1. Open Settings.
2. Click on Network & internet.
3. Turn on the Wi-Fi toggle switch.

Alternatively, you can turn on the wireless adapter by opening the Quick Settings flyout (Windows key + A keyboard shortcut) and clicking the Wi-Fi button.

Also, ensure the physical wireless switch is turned on if you have a laptop. Otherwise, you won’t be able to see or connect to any network.

Connect to wireless network

If there’s a connection problem, you may be able to get around this problem by disconnecting and connecting the device to the access point.

To reconnect to the wireless network on Windows 11, use these steps:

1. Open Settings.
2. Click on Network & internet.
3. Turn off the Wi-Fi toggle switch.
4. Turn on the Wi-Fi toggle switch.

1. (Optional) Click the Wi-Fi setting if the computer doesn’t connect automatically.
2. Select the wireless network under the «Show available networks» setting.
3. Click the Connect button.

1. Continue with the on-screen directions to connect.

Once you complete the steps, you should be able to connect to the internet.

If you’re on a network with a router that offers different frequency bands (2.4GHz and 5GHz), you can try to switch bands to make a reliable connection.

Re-enable network adapter

On Windows 11, an update can inadvertently change settings without your consent, including disabling the network adapter or turning on Airplane mode. 

If the network adapter is suddenly missing, it could be an issue with the drive, or the adapter might be disabled.

1. Open Settings.
2. Click on Network & internet.
3. Turn off the Airplane mode toggle switch on the right side.

Reset wireless profile

The system creates a profile with connection details and credentials as you connect to a wireless network. If the profile gets corrupted during an update or due to another action, the computer won’t connect to the network. In this case, you can delete and recreate the profile to fix the problem.

To recreate a wireless profile on Windows 11, use these steps:

1. Open Settings.
2. Click on Network & internet.
