I have been using Nmap for scanning projects. Along with Nmap package NPCAP adapter also got installed in my Windows 10 machine. After it was installed my device WiFi stopped working. After long troubleshooting i came to know that it was NPCAP adapter was causing the issue and as i disabled that driver WiFi started working (connected).

I have changed my machine to other windows 10 one and issue is same there also.

Thank you for reporting this. Please try the following steps:

  1. Install the latest Npcap (Npcap 1.31 at this time). The Nmap installer does not contain the latest Npcap installer, and the issue you are reporting may have already been fixed.
  2. Ensure you are not using the "Legacy loopback support" option. This is only needed for older versions of Nmap, and is known to cause problems similar to yours.
  3. Remove any leftover loopback adapters from previous partial/broken installations. Open devmgmt.msc, expand "Network adapters," right-click any "Npcap Loopback Adapter" and choose "Uninstall device."

If the problem persists, please follow the directions for reporting bugs in the Npcap User's Guide regarding DiagReport and other important information. Thanks!
