Hello,
These days I try to capture the packets in WLAN. I follow the wiki page CaptureSetup/WLAN. I am almost successful, except that all outgoing packets which are not sent by myself disappear.
That is to say, I can only find HTTP responses, DNS responses and so on while all HTTP requests and DNS requests from other computers in the same WLAN disappear. However, those requests from my computer are captured successfully.
Is there any reasonable explanation and any solution to the problem? Or is it caused by buggy hardware? I searched Google for a long time but I got nothing.
I'm using Archlinux with Linux kernel 5.4.2 and my network card is Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter.
Thank you for your help!
