STA doesn't support ACM for QoS

STA doesn't support ACM for QoS

[Cyril Seg]

Hello ,

In my testbed, there is an AP that works with ath9k_htc and hostapd and there 
also are 2 STAs that work with ath9k_htc.
Video flows aren't in the good priority, they are in Best_Effort.
But if I enable the ACM parameter for VIDEO and BEST EFFORT, video flows are 
now in BACKGROUND priority.
STAs doesn't support the admission control ...

Does someone have a solution ?

I work with Kali Linux, kernel 3.7

Thanks,

Cyril Segretain

See what ToS bits are in your video frames.   Some definitions
of ToS had low values for video (32), but wifi requires different
settings (something like 128).

The ToS for Video Streaming should be at 160.
But in my testbed all ToS bits are 0. I don't know why...
