I've discovered something called the Npcap Loopback Adapter in my available networks on my Windows 10 computer. 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? Note: This reply has been translated to English to benefit users facing same issue. Did this solve your problem? Yes No. Sorry this didn't help.

My speed was consistently low whether I used my hard wire cable or wifi-- what a puzzle! Disabling the adapter did not appear to work, so I went to Device Manager and removed it. I did not change any other settings nor have I installed any software recently. What I don't know is why this adapter suddenly appeared, and what installed it. It does not appear so far on two other Windows 10 computers in my house. But I am keeping a wary eye on all of them.
