This issue may occur if unsupported VPN software is installed in Windows 8.1 and is present during the upgrade to Windows 10. This affects connections that are made through either a built-in Ethernet adapter or a USB Ethernet adapter. This problem may also prevent wired Ethernet connections from functioning correctly. If you restart the computer or try to reinstall the wireless network adapter driver, this does not fix the problem. This is true even when the wireless network adapter seems to function correctly. When you upgrade this computer to Windows 10, it may no longer be able to detect a wireless connection. You have a Windows 8.1-based computer that has virtual private network (VPN) software installed.
