FreeBSD mesh-1d04 10.0-CURRENT FreeBSD 10.0-CURRENT #4: Thu Oct 11 14:00:10 SAST 2012 root@magrathea.meraka.csir.co.za:/var/scratch/10-current/obj/arm.armeb/var/scratch/10-current/src/sys/SMALL-AVILA-ALTQ arm
>Description:
802.11n does not work between two 802.11n wifi devices when they are configured in ADHOC mode. 11n works if the same two devices are configured as an AP/CLient mode.
HW = gateworks ARM
OS = FreeBSD 10.0-CURRENT
Build = arm-10-20121011
Wifi = RouterBOARD R52nM = AR9220
- Disabling ampdu does not have any effect - ifconfig wlanX -ampdu
- Looks like the MCS rate stuff isn't being setup or negotiated right.
>How-To-Repeat:
- Configure two atheros 802.11n wifi adapters in ADHOC mode.
- Transfer some data between the two devices.
- Run athratestats - note that it never uses rates above 54Mbps.
