WMM 802.11e on Intel Dual Band Wireless-AC 8260

[RQ]

Hello.

I capture traffic with Microsoft Network Monitor 3.4 and get a strange behavior with an Intel Dual Band Wireless-AC 8260 card (WMM certified, driver 19.10.13.1), connected to a Cisco Access point (2702I) with QoS enable.

IP packet are well tagged on both direction (up and downstream) as DSCP 46 for voice traffic by the application, but:

- in downstream, Qos Control Priority (UP) is set to 6 (AC_VO voice) by the access point: this is a correct comportement

- in upstream, no mark of any : this is the purpose of my question

Does the wireless card able to set the WMM UP field? Is anybody have more information about this?

Hello, i Got the same issue and tryied capturing packets over the air using network monitor 3.4 and an open ssid, traffic is well marked with qos UP for upstream evenbt that capturing within sender pc dont shows it,

dscp46 => 5 UP as Microsft uses 3 MSP of the dscp to generate UP tag https://clnv.s3.amazonaws.com/2018/usa/pdf/BRKRST-2515.pdf https://clnv.s3.amazonaws.com/2018/usa/pdf/BRKRST-2515.pdf
