Slow 6ghz speeds axe3000 USB Adaptor

[keezz]

I have installed a  AXE3000 USB 3.0 WiFi Adapter (A8000) with the latest drivers from Netgear (V 1.0.0.125) into my new PC running Windows 11. Its getting faster speeds at 5ghz than at 6ghz from my new BE9300 Router. Does anyone have any ideas?  I am getting fast 6ghz speeds on other supported devices just not this device.

6ghz doesn't have the same broadcast distance as 5ghz, so you'll see a faster drop off in speeds than 5ghz. 

What actual speeds are you getting?

Hi Guru thanks for replying, around 850Mbs on a working device right next to the PC getting around 350Mbs.

are you using the standalone driver the the axe3000 adapter? 
I don't have that adapter to dive into its settings and see whats modifiable.
