After investigating this issue, it became apparent that there are several different scenarios that might ultimately cause this problem. Here’s a list of potential culprits that you should be aware of: Now that we went over every potential reason why you might be experiencing this problem, let’s get to the fixing part. Below you’ll find a collection of methods that other affected users have successfully used to get to the bottom of this issue and enable the mobile hotspot functionality while preserving Internet access on the Windows 11 PC. 

1. Uninstall the KB5014699 update

Numerous people have confirmed that yet another Windows Update (KB5014699) that Microsoft quickly removed is the most likely offender that could be the root of this issue. Did your Windows PC install the KB5014699 update recently? If so, uninstall it from your Windows PC and hide it using a specialist program (to prevent a subsequent installation). Many people who resolved this problem on their own discovered that uninstalling the KB5014699 feature update and restarting their computer helped them resolve the problem. Notably, this bug has already been fixed by Microsoft, so when WU installs this feature update, it shouldn’t occur again. We’ve also included extra instructions that will let you hide the update and prevent it from running in the future. The steps listed below can be used to delete the most current Windows feature update: If the same type of issue continues, proceed to the next procedure stated below.

2. Update Windows to install the hotfix

If the method above didn’t work for you or you want to avoid uninstalling a Windows update that has already made its way to your PC, one of the alternatives is to install the hotfix that Microsoft has made available (KB5014668). Since this update is now part of all channels, the easiest way to install it is by accessing the Windows Update component and installing every pending update automatically Several users that we’re also dealing with this hotspot issue have confirmed that the issue went away on its own after they made sure they updated Windows 11 to the latest version. Here’s how to do this: If the hotspot feature still takes down the internet on your Windows computer, move down to the next method below. 

3. Install KB5014668 manually via MUC

There may be situations when Windows Update is irreparably damaged, in which case the hotfix won’t be installed automatically. You can manually install the hotfix that will repair the problem in your situation using the Microsoft Update Catalog if you don’t want to reinstall your operating system. You can manually deploy the failing update via the Microsoft Update Catalog if the Windows Update component isn’t working properly and the WU Troubleshooter can’t fix the problem. You can manually install the incompatible update version from this location using the.ini file after downloading it from here. For comprehensive instructions on how to manually install the KB5014668 hotfix update, refer to the procedures listed below: Move on to the following procedure if the issue continues and you keep losing internet access when attempting to set up a mobile hotspot.

4. Reset the network connection

You can anticipate seeing this behavior as a result of a network irregularity, according to a number of users who report that we are also experiencing this issue. A set of Powershell commands should be used in this situation to update Winsock, the IP data, the DNS data, and the firewall cache. To test if this scenario is true, open up an elevated Powershell command and run a series of commands while pressing Enter after each one.  Here’s how to do this: If the problem is still not resolved or you’re using a 3rd party Firewall, move down to the next method below. 

5. Disable or Uninstall 3rd party firewall

After blocking the hotspot due to a false positive, it finds out that a few 3rd party antivirus suites are known to indirectly trigger this behavior. Most frequently, Norton Antivirus is to blame for this kind of conduct. If this applies to you, you can start by turning off your antivirus’ real-time protection. You can usually do this directly from the AV suite’s tray bar icon using third-party antivirus software. If you have a firewall and believe that this may be the cause of your problems keeping an Internet connection while the hotspot is enabled, turning off real-time protection alone might not be sufficient to solve the issue because the same security rules will still be in effect even when active network filtering is turned off. The only solution, in this case, is to remove the third-party firewall manually while making sure that no files are left behind that could still result in this problem: If the problem persists, go on to the next possible solution.

6. Reset or Reset Router

Restarting or resetting your router is another option you can attempt if none of the previously mentioned fixes have worked for you. This problem might be fixed by a straightforward restart or a somewhat more involved reset because it might be brought on by a network discrepancy. You can reset your network components by performing a straightforward network reboot without changing your login information or other settings. So when you force a network refresh, there is nothing to worry about. Press the restart (switch) button if you want to restart your router. Use the ON/OFF button and press it twice if this option is not accessible. The identical outcome can be achieved by just unplugging the power wire from the socket. Note: Avoid pressing the RST button, as doing so will start a reset process. If you’ve already tried this and the problem persists, you can try performing a router reset. However, you should be aware that this process will also reset your modem’s default address and custom credentials. Notably, your login information will also be changed back to admin for both username and password. All that’s left to do is press and hold the reset button for at least 10 seconds. Depending on the router model, you might require a small, pointed device to reach the reset button. When the process is finished, the router’s LEDs will begin to sporadically blink. If your internet access still gets interrupted when you enable the mobile hotspot, move down to the next method below.

7. Update network adapter

Make sure you’re using a network adapter that is compatible with Windows 11 as soon as possible if you have this problem right away after upgrading from Windows 10 to Windows 11. If an incompatible version was transferred from an earlier Windows version, you can upgrade it through Device Manager. In this situation, you’ll need to restart your computer after using Device Manager to completely delete the active network adapter driver. By doing this, you’ll compel Windows 11 to recognize that a crucial driver is absent and install a generic alternative (one that is totally compatible) the following time your machine boots up. Follow the steps below for step-by-step instructions on how to do this: If you’re still having sporadic disconnections while connected to a Wi-Fi network after reinstalling the network adapter, scroll down to the next possible solution below.

8. Enable IPv6 

Remember that the primary hotspot feature that comes included with Windows 11 uses IPv6. When IPv6 is disabled for your active network and the hotspot is forced to use IPv4, one scenario where this issue could occur is. If you only experience this issue when using a certain program, it’s probable because that application was only created to support the new IPv6 protocol. To drive them out of IPv4 in this situation, the only option is to enable IPv6. For detailed instructions on how to do this, go to the list below: Continue to the next method below in case you’re still losing the internet connection while enabling the mobile hotspot functionality.

9. Use System Restore

If you’ve tried all of the methods indicated above to undo a system modification that isn’t disrupting the Internet connection while the mobile hotspot component is activated, your next option is to roll back your machine to a previous system restore point. Some users have found the issue to be resolved thanks to this. Note: The System Restore feature of Microsoft Windows allows you to return your machine to a previous state. This can be used to fix problems like faulty systems. Follow the instructions below to get your computer back to working order: Continue to the following potential remedy below if the same type of issue is still present.

10. Perform a clean install or repair install

The only reason if you’ve reached this point without finding a workable solution is that your system is experiencing some kind of underlying system file corruption that interferes with its capacity to establish and sustain mobile hotspot connections.  The only plausible solution at this stage, assuming you’ve ruled out a signal problem (the router is too far away), is to completely replace each system file with a healthy equivalent. There are two ways you can accomplish this:

By performing a fresh install of Windows 11– Expect the process to be as simple as possible if you choose this path. Window 11’s settings menu allows you to initiate a clean install without having to plug in or insert appropriate installation discs. The disadvantage is that you risk losing all of the data stored on the Windows drive if you don’t back it up beforehand.By repairing and installing (or upgrading in place) Windows 11 – Deploying a repair install would be a more elegant solution (in-place upgrade). Since this procedure just replaces Windows files, you’ll be able to preserve all of your files, programs, games, and user settings. You must, however, use Windows 11 installation disks that are compatible.
