WiFi Driver update as well as bluetooth driver both not working

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.

regards,

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!

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.

After following these steps I still had the problem of v 7.77.110.0 comming back over and over again.

Consider uninstalling v 7.77.110.0 by selecting "uninstall device" from device manager, and tick the "delete the driver software for this device" box : http://myitengineer.com/windows-10-wifi-connected-but-no-internet-macbook-with-bootcamp/

• Do you have BT/WiFi collaboration setting in 7.77.110.0 driver?
• What is the year/model of your Mac (do not post the serial number)?

What are the Power Management settings for BT and WiFi drivers?

I have the issue as well with the new Broadcom - Net - 7.77.110.0 driver. Glad I came across your post. I reinstalled an older version of the driver and it worked.

Are you currently running W10 1903 or later? W10 1903 and later have issues with MacHALDriver.sys?

Do you have access to a W10 1809 ISO? If yes, we should try to remove the current installation, and try to use W10 1809 and check the installed drivers.

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>

				<DriverVer>07/31/2015,6.0.6100.0</DriverVer>
				<ServiceBinary>AppleBtBc.sys</ServiceBinary>

W10 Automatic Updates provided the driver that you currently have.

In dual-band networks, some driver versions prefer 802.11n, while others prefer 802.11ac. What type of a WiFi network do you have?

You may want to remove the existing BT driver using pnputil.exe. Does the Windows Device Manager show an Apple Broadcom BT device as unknown?

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!
