Broadcom 802.11ac Network Driver in Bootcamp Windows 10 install

I have a Macbook Pro from 2013. My network speeds were great, but Windows 10 pushed a new device driver update and now my wifi network speeds have dropped to 20% of what the should be.

I was able to consistently "roll-back" my driver, but recently Windows pushed two driver updates and now the old driver that was working great is gone and I cannot locate it.

The Apple Bootcamp Drivers package for my machine does not include drivers for Windows 10.

Does anyone have any suggestions or procedures for determining the best driver version on Windows 10 for my 2013 Macbook pro Broadcom Wireless card? And where I can find that particular driver?

Thanks.

MacBook Pro 15″, macOS 10.15

A 2013 Mac should have BC drivers in the original BC drivers package which can be obtained via BC Assistant t-> Action -> Download or Brigadier.

If neither is satisfactory, you can search for WHQL drivers using the PID/VID of the Wireless card in https://www.catalog.update.microsoft.com/Home.aspx .

Hi Loner T,

After the bootcamp driver reinstall, the device driver listed was the latest window driver for that device.

I assumed that there was something else that was hidden during the bootcamp install that allowed the latest windows driver for that device to work properly.

That day the speeds were great, at the rates they should be.

Today, the connection speeds have again slowed to half of what they are supposed to. The only change that took place was that I booted down to work on my Mac side during the weekend, and today booted up the Windows side for work. Now, slow speeds again. I'm not sure what to try.

Hi. I did reset the SMC as suggested. Today was the first day logging back into my windows side. Speed is very poor.

Windows Wifi is 2.42mbps

My iPhone Wifi is 234.10mbps

Any suggestions for what to try next? Thanks Loner T

Loner T, thanks. In the end I did a fresh install of all the Bootcamp drivers and it now the connection speeds are inline with where they should be. Thanks.
