Hello. I found some kind of "degradation" in a driver for adapter Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter Generally, "airodump-ng" utility works with firmware-5.bin but doesn't work with the latest firmware-6.bin. https://forum.aircrack-ng.org/index.php/topic,2545.msg13665.html#msg13665 Can you have a look? B.R., Alex
