Banana Pro How to Set Mandatory Wifi Rate

[amikoutsky]

Hi!

 

I have banana pro, 5.15.93-sunxi #23.02.2 (bullseye), and use internal wifi adapter as a wifi client.

The medium btw my client and ap is instable, there are frequent rate changes (6Mbps...54Mbps), so in order to get rid of it I need to set mandatory wifi rate no more than 6 Mbps.

Give me the hint, please:

1. To set wifi rate strictly to 6 Mbps. I had tried iwconfig wlan0 rate 6M - I got "Error for wireless request "Set Bit Rate" (8B20) :
    SET failed on device wlan0 ; Operation not supported." .

2. To adjust 802.11n parameters (rate, number of spatial streams and so on).

 

Thank you in advance,

Aleksei
