Rock Pi X WiFi data rates limits

I have the Rock Pi X drivers loaded from the Downloads page and the 802.11ac WiFi is working.

I tested the data rate with a few methods with the 2.4GHz and 5GHz WiFi and even though my other computer with 802.11ac gets about 42Mbps with 2.4GHz and 101Mbps with 5GHz with the network, the date rates are about 10-15Mbps with the Rock Pi X with similar WiFi signal strengths.

Any ideas of what the slowdown might be?

are you using the default antenna?

I have the Rock Pi X case with the supplied external WiFi antenna connected.

The WiFi system is getting 84% signal strength via that antenna on either band.

Yes, it is the WiFi default antenna.

Any ideas of what to investigate for the WiFi low data rate capability with Windows 10 on the Rock Pi X?

Can you take a screenshot of the device manger, and show the wifi driver version? Just to make sure we are using the right one.

Here is the Broadcom WiFi driver that I loaded from the Rock Pi X downloads.

Is that the correct Broadcom WiFi driver for Windows 10?

Any information on the correct Broadcom WiFi Driver from my post above?
