Hostapd wifi speed not reach the maximum in Debian11

Hello,

I would like to ask if any one know how to make hostapd wifi AP speed reach 850Mbps , my hostapd.conf not reach more than 100 Mbps.

Please note I tried any comment line for reach the make line speed (850 Mbps)

Which device you are using? You should look into iw list which channels allow multichannel (mostly configured channel is centered)

I am using BPI R3 I tried channel 36 and the same result (100 Mbps)
