Reduced speed USB-AX56

[roelandg]

Hi,

Thanks for providing this driver.. No issues with installing, all went according to the instructions. However, I'm facing a reduced speed. Won't call it slow, as I max. at 250 mbit/s down. However, this is far behind my other wifi adapter (+-800 mbits, same location, non wifi =6).

        channel 108 (5540 MHz), width: 80 MHz, center1: 5530 MHz
        txpower 12.00 dBm

What I can see is the txpower (12.00 dBm) is less then my other adapter (22.00 dBm). However increasing the txpower didn't succeed using:

iw dev wlx04421a5f8d5b set txpower fixed 2000

Are there any (other) driver settings I can tweak, to increase the speed of my connection?
