Hi everyone,

In our system we are constrained to use wpa_supplicant and not hostapd to enable/configure AP mode. Our chip supports up to 802.11ac (VHT) mode and we are trying to enable it using only wpa_supplicant but we have not be able so far.

Using hostapd we was able to set the system in VHT to verify hw capabilities. So, we tried the following network configuration with wpa_supplicant to do the same and it successfully started but in 802.11n (HT) mode. There is something we are missing?

set_network 0 ssid "Marvel-AP"
set_network 0 mode 2
set_network 0 psk "123456789"
set_network 0 auth_alg OPEN
set_network 0 pairwise CCMP TKIP
set_network 0 group CCMP TKIP
set_network 0 frequency 5180
set_network 0 vht_capa 868250096
set_network 0 vht_rx_mcs_nss_1 2
set_network 0 vht_tx_mcs_nss_1 2
set_network 0 disable_ht 0
set_network 0 disable_vht 0
select_network 0

Additionally, we have not found any parameter to set the channel width because this parameter is present in the VHT Operations and not in VHT Capabilities (Which clearly can be set using vht_capa). Is it possible to set this parameter?

Thanks in advance for your help.

Best regards,

Jose Blanquicet
