Flint 2 Wifi 6 2.4 ghz width band issue

today I tried to understand what a lot of people have been experienced about low transfer speed on 2.4 ghz band.

The real issue is that Flint 2 isn’t able to work at 40 mhz but only at 20 mhz width bas and the real maximum transfer speed is limited to 130 megabit in Dw and UP.

I’ve the 4.5.6 firmware on my Flint 2 .
