Interesting, thanks for sharing your results! If these settings are generally diserable, maybe it might make sense to patch hostapd to set them by default if they aren't set explicitly, instead of through netifd? That way anyone, not only OpenWRT users might benefit from it. Cheers, Linus
The thing is - this parameters I've got from hostapd.conf on my host machine and due to comments they are strictly set from 802.11. As for hostapd itself, I don't gone in deep inspection of WMM part but I saw some default values regarding tx_queue* parameters (according to comments this section is used to prioritize traffic from AP to STAs, and WMM part is in opposite direction, in my oppinion last one is also used to determine WMM capable stations which gives us such speed improvements) in source code of hostapd, maybe there's some analogue for WMM but somehow it don't get applied when configuration file loaded. So for now the easiest and fast way to fix this is to set config with parameters that hostapd expects. 2015-06-29 0:21 GMT+03:00 Linus Lüssing <linus.luessing@c0d3.blue>: > On Sun, Jun 28, 2015 at 09:16:58PM +0300, N.Leiten wrote: >> As a result I got full 100Mbit/s on AR71XX platform and 70-80Mbit on >> Ralink.

In vanilla trunk versions of openwrt I got nearly 40-45Mbit/s speed on Ralink RT5350 based devices and Atheros AR71xx platform (tp-link wr841nd). The problem was in /var/run/hostapd-phy0.conf. It seems it is not enough just set 'wmm_enable=1' to actually enable WME/WMM on interface, it also need all WMM related keys be set. So I just added it with standart definitions from hostapd.conf to /lib/netifd/hostapd.sh. > > As a result I got full 100Mbit/s on AR71XX platform and 70-80Mbit on Ralink.

Sorry, I must admit that there was a mistake in my tests. Patch already declined.
