Tested on the following device with speedtest-cli looks like I'm seeing improvement. iwx0 at pci3 dev 0 function 0 "Intel Wi-Fi 6 AX200" rev 0x1a, msix iwx0: hw rev 0x340, fw ver 63.c04f3485.0, address 50:e0:85:xx:xx:xx My AX200 is now getting ~48 Mbps down / ~19 Mbps up where before I was getting ~28 Mbps down / ~13 Mbps up. I got a message "iwx0: device timeout", but didn't see fatal firmware errors.
