WiFi Driver update as well as bluetooth driver both not working

"Cold boot Windows instead of restarting from macOS" is a workaround. Don't know what causes bluetooth not functionally when warm reboot from Mac OS. By following below steps, my bluetooth back to work. Still a bit inconvenient but at least it works.

1. In macOS or Windows, Shut Down completely
2. Wait a 3-5 secs (just let all the caches clear)
3. Power the computer and immediately hold Option and boot into Windows. Do not let macOS load, if it does restart at Step 1.

My WiFi is compatible with both 802.11n and 802.ac. With the new driver it works with 2,4ghz but not 5ghz

Correct, your Mac supports both. 11n works in both 2.4 and 5gHz bands, while 11ac is 5gHz only.

The older .83 driver supports both 11ac and 11n, but prefers 11n in 5g. Based on what you are reporting the new driver only sees 2.4g. I have the .73 version, which works correctly on both.

Same problem for me with a macbook pro retina late 2013 running windows 10 with bootcamp. Windows update automatically installed "Broadcom - Net - 7.77.110.0" driver and my wifi could'nt connect anymore with 5ghz wifi networks.

Had to go back to 7.35.118.83 using the device manager : select Broadcom network adapter -> update driver -> search on computer -> choose in the list... -> and select the previous version.

Problem is each time my computer restarts, the new driver is installed back automatically. To disable auto driver update, I had to follow this guide : http://woshub.com/how-to-turn-off-automatic-driver-updates-in-windows-10/#h2_2

This workaround works, but I hope they soon release a new driver update to solve this issue.

Okay well I don’t have a workaround for your problem, but I’d just like to say THANK YOU!! I couldn’t figure out what was going on with my computer. Spent hours last night troubleshooting. Your solution of reinstalling a previous driver worked like a charm!

As I mentioned in the post, Power Settings are deactivated. This means:

- in Device Manager in both driver settings under "Power Managemenr" tab are both power checkboxes of allowing switching off the device or waking up the PC both unchecked

So these are correct, as expected.

- in Power Options in Control Panel is WiFi Power Setting set to "High Performance"

This should be fine, too.

For the bluetooth, the current and only installed driver is an official Microsoft Driver with version of "10.0.18362.449". But the problem with bluetooth and since the first day I installed Windows 10 through BootCamp is that the bluetooth is just not working! It sees bluetooth devices, but it will never connect. It hangs on "Connecting" and after waiting for more than 30 minutes nothing happens.

I tried uninstalling, reinstalling, even downloading Windows Support Drivers. Nothing helped. I reinstalled Windows. NOTHING helped.

Your BT issue is a bit more interesting. The currently-running version came from KB 4522355 (October 24, 2019—KB4522355 (OS Build 18362.449)) and was provided by Microsoft, not Apple.

The original Apple BT driver is from

<ProductManufacturer>Apple Inc.</ProductManufacturer>
<ProductVersion>6.1.6660</ProductVersion>
<ProductCode>{FCFFE6B6-BAE8-490E-88D0-097A9DA1C43D}</ProductCode>

and the version included in that package is

<Name>Apple Broadcom Built-in Bluetooth
				<InfName>AppleBTBC.inf</InfName>
				<Class>Bluetooth</Class>
				<ClassGUID>{e0cbf06c-cd8b-4647-bb8a-263b43f0f974}</ClassGUID>
				<CatalogFile>AppleBTBC.CAT</CatalogFile>

W10 Automatic Updates provided the driver that you currently have.

Had the exact same issue and it took me 3 days to finally sit down and crack the problem. Hopefully Microsoft comes out with an update to fix the issue as opposed to having revert to a previous install. But glad to see there is a workaround.

Yes this is an issue with the most recent driver pushed out by a Microsoft update. You can easily rollback the driver (don't even need to restart, usually!).

The symptoms are certainly strange. It does not affect all applications, or even all websites on a given machine. Just strange interruptions and dropouts.

I have also seen it affect just Dropbox on a MacBook 12", whilst all other internet on the machine via Wifi was fine.

As soon as the driver is rolled back, everything starts working.

Roll back the driver by opening Device Manager (search from the start menu).

Then find the Network section, expand it and right click on the Broadcom interface. Choose Properties from the contextual menu. Then go the Driver tab. From there you should have a Roll Back Driver button.

Click on that and confirm any messages you get, then the previous working driver should load.

If you don't have the Rollback Driver button, you may need to restart and login as an Administrative user.

Hope this helps!
