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

<br>Arend
