I'm describing my problem with AX200 and AX210 mini PCIe chinese version cards:
My computer: Fujitsu AH531/GFO (i7-2820QM - HM65 chipset - Windows 10 Pro 20H2) I was using Intel Centrino Wireless-N 1030 and nextly Intel Dual Band Wireless-AC 7260 in this laptop.
I placed both this cards on my laptop. Bluetooth works perfectly but WiFi shows code error 10:
I installed newest drivers and tested many drivers:
I upgraded chispet driver from version 126.96.36.199 to 188.8.131.52. Problem still happend.
The BIOS is the newest - 1.24. I updated all drivers - Fujitsu BIOS driver too. Problem still happend.
So I put this cards to Dell Latitude E6520 (QM67 chipset) with the same drivers like in Fujitsu. Cards works perfectly on Dell! No error / code 10!
Nextly I putted HDD from Dell (where everything works good) to Fujitsu. And... code 10 for AX210 card happend in Fujitsu with HDD(system) from Dell.
Anyone know what I have to do to use WiFi6 card on Fujitsu AH531/GFO?
