Why hostapd return hw vht capab: 0x0, conf vht capab: 0x0 if firmware contained wl18xx.ht.mode = 0x01 and hostapd.conf contained ieee80211n=1 and ht_capab=[HT40-][SHORT-GI-20][SHORT-GI-40]?

How can I enable 40MHz channel width?
Thank you and excuse my bad english.

    hi , Wilink8 doesn't support 40MHz channel in 2.4GHz band in AP role. It is only supported in station role.
    It does support 40MHz channel in 5GHz band in AP/sta role.

    Why speed not increase on 40MHz width channel?
