What's the status of 802.11AC support?

Hi Arend, and thanks a bunch for the configuration!
As far as I understand it, the higher speeds of 11ac is dependent on both modes operating simultaneously
and in cooperation. Is this correct?
You’re saying that all my STAs needs to be 11ac compatible, but one of the main reasons I’m switching to 11ac is due to
the vary of different clients that connects to our network, there’s even a few 802.11g clients (cellphones mainly).
According to different sources and specifications 11ac is supposed to be compatible with both a/b/g/n/ac,
I suppose this is due to it’s operation on both modes as well?
I’m curious, what speeds do you measure with that setup, and with what chipset / NIC?

The higher speeds in 11ac are depending on bandwidth doing 80MHz and
higher and some more stuff that falls under the term MCS. Anyway, 11ac
is only available in 5GHz. Probably stating the obvious but both AP and
STA clients must be 11ac capable. Attached is a sample config I used. It
is a bit tricky. The channel indicates the operating channel. I used
channel 36 and for 11ac you have to specify the center frequency using
vht_oper_centr_freq_seg0_idx, which is 42 in my case for 80MHz bandwidth
(vht_oper_chwidth=1). If I am not mistaken vht_oper_centr_freq_seg1_idx
is only used for 80+80 bandwidth.
