Unfortunately, there might be some issues on your new operating system, and speaking of which, users have reported network adapter problems in Windows 10.
This is a big problem since most of us use internet on daily basis, but luckily for you, you can fix this relatively easy.

If you experience network adapter issues in Windows 10, follow this

Solution 1 – Uninstall antivirus software before upgrading.

If you’re installing Windows 10 for the first time, you are probably upgrading from Windows 7 or Windows 8. By upgrading you’ll keep your software and settings, but this can sometimes be a problem, especially with your internet connection. Before upgrading make sure that you uninstall your third-party antivirus and then perform the upgrade.

If you have already upgraded you can revert back to the previous version of Windows, uninstall your antivirus and try upgrading to Windows 10 again. If you’ve switched to Windows 10, you can also try uninstalling your antivirus from Windows 10, and checking if your network adapter is working after the restart.

Solution 2 – Check your BitDefender settings

BitDefender Internet Security 2015 is known to cause issues on Windows 10 after the upgrade, but you can fix this by going to the advanced settings of BitDefender Firewall. There’s an option called Block Internet Connection Sharing that you need to switch off. After turning this option off you network adapter should start working again. It appears that BitDefender turns this option for some reason, and it has been confirmed by users that disabling it restores your internet connection.

Solution 3 – Perform a clean install

In most cases deleting your antivirus software fixes these issues, but if that fails, you can always perform a clean install of Windows 10. This is a last resort in case that deleting your antivirus software doesn’t help.

If you’re still having issues with your hardware or you simply want to avoid them for the future, we recommend you to download this tool (100% safe and tested by us) to fix various PC problems, such as hardware failure, but also file loss and malware.
