    I don't actually know what this thing is, but it's giving me weird errors. My connection is acting up as well. I've run troubleshooting, and it just keeps restarting this adapter, but it never works

  3. The Npcap Loopback Adapter

    maybe is to late but thought would be helpful, Npcap loopback is part of the Nmap software Npcap is prerequisite software for Nmap , you download Nmap on your PC, by default it will create loop back adapter for capturing data purpose simply uninstall
    Ncap it will go away.but Nmap wont work properly you will have to uninstall both

    Npcap loopback adapter isn't working

    The Npcap Loopback Adapter

    Hi Guys,

    I've discovered something called the Npcap Loopback Adapter in my available networks on my Windows 10 computer.


    Npcap loopback adapter isn't working 017f4814-8018-458e-ad00-3c604da193d1.jpg


    Does anyone know

    1. what it is;

    2. where it came from (which software); and

    3. what is its function or what does it do.

    I am a little sceptical about this Npcap Loopback Adapter thing and it seems it only appeared after the latest Windows 10 upgrade. Am I correct?

    Thank you in advance.

    Regards,

    Andrew
