Hello, can anyone share his hostapd.conf where he managed to get HT40 "width: 40 MHz" running on orange pi lite 2 while it is in AP mode ?

Did you try armbian-config way of setting AP? How far it gets?

Hi Igor. I did make Hotspot in armian-config and hostapd.conf it generated is below. I was able to connect to it without problems.

But right now I'm not using this hostapd.conf but rather my own manual stuff via rc.local and custom hostapd.conf file that are below and I want to leave it that way if possible but with HT40 speed of 150Mbs, now is 75Mbs. I also have this Acces point connected to my 4G modem via ethernet wich than shares internet to wifi clients. It works ok, but I want more speed.

enx00e04c6800b0 is an Ethernet adapter plugged into USB 3.0.
