Fixing the Cisco AnyConnect Client in Windows 11
Here are a few methods that you can try if the Cisco AnyConnect client stops working on your Windows 11 device. However, before attempting any fixes, make sure that if you have any other VPN client other than the Cisco AnyConnect, you disable it before troubleshooting. Another VPN client may interfere with the Cisco AnyConnect client and prevent it from functioning correctly on your Windows 11 laptop or PC.
1. Allow Cisco AnyConnect through Windows Firewall
If the Cisco AnyConnect VPN client stops working on your Windows 11 PC, especially after an update, you should first check if the Cisco app is allowed in Windows Defender settings. In such cases, third-party apps like Cisco AnyConnect may be disallowed for free traffic through Windows Firewall, preventing the program from operating.
To fix this issue, follow these steps:
1. In the search bar on your Windows 11 Taskbar and search for “allow an app” and open the “Allow an app through Windows Firewall” option that appears in the search results.
2. In the next window, ensure that the Cisco VPN is on the list of allowed apps and is checked.
4. If the app is not on the list, click the “Allow another app” button and add Cisco VPN. Make sure to click on the Change settings button if the Allow another app button is greyed out.
5. Make sure that the checkboxes for both Private and Public are checked for Cisco VPN.
2. Repair Cisco AnyConnect Client
If allowing the Cisco AnyConnect client through Windows Firewall did not resolve the issue, you can try repairing the program’s installation from the Control Panel in Windows 11. Repairing the installation of the program from the Control Panel can fix minor issues in the client and restore its functionality.
Follow these steps to repair the Cisco AnyConnect client installation in Windows 11:
1. Use Windows search to search for Control Panel and click it to open.
2. Click the “Uninstall a program” option under the Programs settings in Control Panel.
3. In the following window, find Cisco AnyConnect VPN on the list and click to select.
4. Click the “Repair” button that appears above and follow the on-screen instructions to repair the installation.
After repairing the program, restart your Windows 11 PC or laptop before opening the Cisco AnyConnect VPN.
3. Update the Virtual Network Adapter
If the first two fixes do not work, you may need to update the virtual network adapter that Cisco AnyConnect uses in Windows 11. An outdated virtual network adapter can cause the Cisco AnyConnect client to malfunction.
To update the virtual network adapter, follow these steps:
1. Right-click on the Start button and select Device Manager from the Quick Links menu.
2. Click on the arrow next to Network Adapters to expand the list.
3. Right-click on the Virtual Adapter option and select Update driver.
4. Follow the on-screen instructions to complete the update.
5. Restart your Windows 11 laptop or PC and try running the Cisco AnyConnect client again.
4. Repair Cisco AnyConnect Using Windows Registry
If none of the above solutions work, you can try repairing the Cisco AnyConnect client using Windows Registry.
However, editing the Windows Registry can be risky, so proceed with caution and follow these steps carefully:
1. Press the Windows + R keys to open the Run tool.
2. Type “regedit” in the text field and press Enter to open the Windows Registry window.
3. Copy and paste the following path into the URL text field and press Enter:
4. Right-click on the DisplayName option and select Modify.
5. Make sure the Data Value section contains the text “Cisco Systems VPN Adapter” (or “Cisco Systems VPN Adapter for 64-bit Windows” for 64-bit Windows).
6. Save the changes and exit the Windows Registry window.
Restart your Windows 11 laptop or PC and try running the Cisco AnyConnect client again.
5. Re-install Cisco AnyConnect
If all else fails, you can try performing a clean re-installation of the Cisco AnyConnect client.
To do this, you must first uninstall the program, delete its saved files and data, and then reinstall it from scratch. Follow these steps:
1. Open Control Panel and select the Uninstall a program option.
2. Find Cisco AnyConnect Mobility Client on the list and select it.
3. Click the Uninstall button to uninstall the program.
4. Open File Explorer and navigate to the following path:
5. Select the Cisco AnyConnect Mobility Client folder and press Shift + Del to permanently delete the folder and its data.
Note: Please note that the folder we are searching for, known as ProgramData, may not be visible by default. Therefore, it is important to ensure that the option to display hidden items is enabled by selecting the “Hidden items” box from the drop-down menu labeled “Show” under the “View” tab.
6. Thereafter, navigate to the following path and delete all the Cisco-associated folders from here as well.
7. Now, restart your PC, download a fresh copy of the Cisco AnyConnect client from here, and install it
