I’ve been testing out wifi-qcom-ac on a cAP ac running 7.15.2. This driver seems to have rather bad per station queuing without any AQM or FQ. Under testing with Crusader the latency increases to above 100 ms following by massive packet loss. This happens on both 2.4 Ghz and 5 Ghz, but the behavior seems inconsistent. A separate station is unaffected by this so I suspect some bad per station queuing. It seems like this could use some SQM like OpenWrt does. Just CoDel or FQ would probably help too. Has anyone else tested wifi-qcom-ac or wifi-qcom for bufferbloat and ran into similar issues?
