16 inch 2019 MacBook Pro running into Broadcom WiFi driver issues on 1909

I was able to get Windows installed successfully on a partition, then went through the process of updating any drivers via Bootcamp Installer.

Now, the only issue I'm encountering is inconsistent WiFi speeds in Windows 10 (MacOS on the same machine doesn't have this issue). My speeds range anywhere from .5Mbps to 180Mbps.

I've tried removing the driver and reinstalling via a WindowsSupport USB Drive, I've also tried deleting the device entirely from Device Manager, and then reinstalling the driver. Still no luck.

I'm not sure what other potential solutions there may be.

Driver version: 101.10.152.3

I also double checked that this was the same driver from the BootCamp.xml file in my WindowsSupport directory.

I should also mention that this is a completely fresh install, so I have no ability to roll back the driver. If anybody knows of there being a previous driver available that would work on the new MacBook Pro's network adapter, that'd be great!

Any help would be great, thanks!

MacBook Pro 16", macOS 10.15

Can you define two different SSIDs - one in each of 2.4g and 5g bands - and test connecting to them individually?

2.4 only supports 802.11n, 5g will support 802.11n and 802.11ac.

.40 is not valid for the new 16-in rMBP.

Can you verify the VID/PID? Are they switched?

0x14E4 is the Canadian subsidiary of Broadcom.

I have an ASUS GT-AX11000

Speedtest tells me that my connection is fairly steady now, but actual downloads are still all over the place. How would I go about tuning the RF?
