Resending patch in text format. Return of wmm_* parameters to hostapd.conf file for wifi speed up. 2015-06-29 0:59 GMT+03:00 N.Leiten nicklei...@gmail.com: 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.luess...@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.

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.

[OpenWrt-Devel] [PATCH] Improve wifi speed up to 2 times in AP mode.
Hi. There's some general problem in hostapd configuration for several devices was observed. 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. I think it is good performance improvement at this moment.
