Troubleshooting AX200 adapter no 11ax

How does one troubleshoot why my laptop, with AX200 Intel adapter, only appears to connect at 802.11a (according to Windows 10)?  I updated the Intel drivers to the latest release (22.50.1), didn't help.  I also checked and AX is enabled on the router, and WMM as well.

Any hints would be appreciated.

      Got a referral to update drivers and use intel's best settings for the adapter, which I've done.  Also updates the CTS as suggested.  Not luck, still connected as 11a protocol.

       

      Anyone else have a AX200 adapter that does get 11ax?

        You may have a faulty adapter that needs to be replaced. I'd try another or a different brand.
