AX200 Windows 10 - 802.11AX radio type showing as 'unknown'

[intercede007]

When connecting to 802.11AX capable access point, Windows 10 is showing the radio type as "unknown". Removed Intel Proset/Wireless software (including saved data), as well as hardware from Device Manager and reinstalled with latest driver. No change.

Anyone know why the driver is showing "unknown" in supported radio types and how I can remedy it?

What is the model number of your device/motherboard?

You are running Windows 10 version 1709, more than two years old. Update to 1903 or 1909, then report back.

Are you using the drivers from your device manufacturer?

Did you add this wireless card yourself or did it come with your device?

• What is the model number of your device/motherboard?
  • Dell Latitude 5490
• You are running Windows 10 version 1709, more than two years old. Update to 1903 or 1909, then report back.
  • Unfortunately that's not a remedy I can attempt at this time. Windows 10 updates are managed by policy. I can't find a Windows 10 OS dependency for 802.11ax support.
• Are you using the drivers from your device manufacturer?
  • See above - Intel driver 21.50.1.1 from software package
• Did you add this wireless card yourself or did it come with your device?
  • Replaced Wireless-AC 8265 for 802.11AX product testing.

You cannot simply replace a wireless card.

I am not surprised it does not work properly. Go back to the 8265.

Regarding windows dependencies, a lot has changed in the past two years.

Thanks for your time Al.

I'm confident the cards I have in my possession are for the same US WLAN channels and do not violate the above FCC regulations.

It's entirely possible that older versions of Windows don't support 802.11AX radio types. If you come across documentation or other resource stating that, please pass it my way.
