I have almost the exact same problem with a 9260 in a Windows 10 . When I run any Intel provided driver my download speeds seemed to be throttled to 30-40Mbps, and my upload speeds aren't much better. I can switch to the Microsoft provided driver v21.10.2.2 and I can get 200-300Mbps and higher with LAN transfers. I also have other computers on my network with Intel Wifi (mostly 8260) and they have no issues with the latest Intel drivers.

I tried a brand new AX210 adapter, but I get the same 30-40Mbps connection. In all cases I confirm with 'netsh wlan show interface' that I'm connected usually at 540Mbps or higher. Since there is no driver alternative I keep it disabled until I can find some sort of resolution.
