If your Wi-Fi network is on one of the forbidden channels, then it won’t be available. The region setting ensures that your router will only let you use the Wi-Fi channels valid in your location and won’t scan beyond those channels. The primary reason for the this setting is that various world regions have allocated different amounts of frequency space around 2.4GHz for Wi-Fi and so some of them have fewer (or more) channels available than others. Wi-Fi adapters also have a region setting. In both cases of incompatible or corrupt drivers, your WLAN network card is not able to communicate properly with your PC therefore your PC is unable to identify wireless networks. Drivers from previous Windows versions are not always compatible with the next version of Windows. Windows 7, 8 or 8.1 will almost certainly cause a driver incompatibility issue.

Updating to Windows 10 from previous Windows versions e.g. Either the drivers are not compatible, or they are corrupt. Usually, this issue is related to the WLAN network card drivers. Reasons why your available Wi-Fi network is not visible in your Wi-Fi list
