iwx0 at pci0 dev 20 function 3 "Intel Wi-Fi 6 AX201" rev 0x20, msix iwx0: hw rev 0x350, fw 77.f92b5fed.0, address X iwx0 at pci0 dev 20 function 3 "Intel Wi-Fi 6 AX211" rev 0x01, msix iwx0: hw rev 0x370, fw 77.f92b5fed.0, pnvm dbd9582f, address X Working fine. AX211 required IWX_UCODE_SECT_MAX 57 to start. Tested with usual activity and iperf3 --bidir overnight.
