In this guide, I have shared various tips to fix nearby Sharing if it is not working on Windows 11. For wireless file sharing, nearby sharing is a useful feature available on Windows OS. If you have files of smaller size to be transferred between two computers, then nearby sharing is a great way to do that.
Due to mismanaged nearby settings, signal obstruction, system bugs on Windows OS, a broken WiFi network, and disrupted Bluetooth services Nearby Sharing may not work on Windows 11.
It also depends upon the type of network both the devices participating in file sharing are using. A public network will result in a slow transfer of files as there would bother devices hooked on to the same network.
