Capturing 11AX HE_MU traffic Alfa AWUS036AXML dongle #321

Open svnas1994 opened 8 months ago

Hi all,

Currently I am using Intel NUC loaded with Ubuntu attached withbAlfa AWUS036AXML dongle for capturing the wireless traffic.. I am able to capture the HE SU packets but unable to capture the HE MU Packets.

But onboard wireless adapter is able to capture the HE MU Packets and display in the wireshark.

I suspect the below command is not getting applied for USB wifi dongles.

echo 0 00:00:00:00:00:00 > /sys/kernel/debug/iwlwifi/*/iwlmvm/he_sniffer_params

Can someone suggest some workaround to resolve the issue

TIA,

Hi @svnas1994

I have an AXML and am somewhat familiar with Wireshark but it would help if I could see this for myself. Could you provide the steps to reproduce this?
