Windows 10: BCM43xx S3 resume firmware initialization problem (MacBook Pro 15 mid 2014)

Hel!o!

Seems to be there is a serious bug in BCM43xx adapter firmware (MacBook Pro 15 mid 2014) resulting in failed S3 resume initialization (wake-up from Sleep) under Windows 10.

Detection algorithm:

1. Using Device Manager completely uninstall Broadcom 802.11ac network driver with option "Delete the driver software for the device".

2. Press "Scan for hardware changes" button to detect device instance named as "Network Adapter" and select "View" -> "Show hidden devices" from menu, so you can see only one "Network Adapter" device.

3. Put your computer into sleep mode by selecting "Power" -> "Sleep" from start menu and some times later resume it by pressing space bar for eg. Now you can see another detected (duplicated) "Network Adapter" device instance as active, but the first one becomes inactive. This is because failed adapter firmware initialization on S3 resume.

4. Reboot your computer, open Device Manager again with "View" -> "Show hidden devices" option to see (vice versa) the first "Network Adapter" device instance as active, but another one (duplicated) becomes inactive. As a result you always have annoying problem with wi-fi network connection after sleep mode until reboot.

Of course you can repeat steps with Broadcom 802.11ac network driver installed, it doesn't matter, because the Apple should provide us with firmware update to solve this hardware problem.

Any other ideas?

Best Regards.

MacBook Pro with Retina display, Windows 10

Anyway there are duplicated device instances in all cases as I can see on your screenshots.

Have you contacted with someone from the bios development department about this issue? If I have to create a trouble ticket to get official update please let me know how to do it? I purchased my new MacBook Pro mid 2014 at September 2015.

Have submitted bug report with link to this thread but without an answer yet. Probably you or someone you know can make a patch to change wrong SUBSYS_0112106B value to the SUBSYS_0134106B for me? Or probably there is a special tool to modify this value in controller firmware or S3 boot script that I can use privately to speed up the solution?

MacBook Pro Retina 15'' mid 2014 BootCamp Windows 10:

Hardware ID before Sleep (PCI\VEN_14E4&DEV_43A0&SUBSYS_0134106B&REV_03) reported:

Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

Subsystem: Apple Inc. Device [106b:0134]

Hardware ID after Sleep (PCI\VEN_14E4&DEV_43A0&SUBSYS_0112106B&REV_03) reported:

Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

Subsystem: Apple Inc. Device [106b:0112]

We need to find a way to get after Sleep the same SUBSYS_0134106B value as before Sleep that means the Apple Inc. Device [106b:0134] is installed in my MacBook by manufacturer.

I assume that OSX doesn't update device list after S3 Resume and doesn't use SUBSYS part of hardware id, so ioreg shows the same BoardID as before S3 Suspend. Do you know a terminal command to force hardware re-scan in OSX after Sleep mode to check it?

Ok I'm going to have to keep an eye on this thread. I've been having wifi issues since I bought my later rMBP 15' 2013. I took it into repair and they put in a new card and it still does the same thing.

The main issues I'm having are..

-- When waking from sleep wifi seems connected but I get no internet activity. (My solution was to turn the wifi off and back on again)

-- Connecting external storage sometimes effects the internet and sometimes I have to force it to unmount. (Turning off wifi solves this issue.)

-- When bluetooth is on and I stream to the Apple TV my internet speed drops down to 3-5Mbps sometimes it's dead. (I have a 50Mbps connection...)

Can you post the output of

In my opinion, device reports "initialized Ok" any time without checking its initialization state. But anyway such behavior is incorrect and should be fixed.

On the OSX side, the same adapter and EFI and firmware seems to wake-from-sleep correctly.

I will check when I have a chance. The Instance path can change based on PCIe discovery order.

Run OSX ioreg command and check after paths of devices before and after sleep on the OSX side.

Sure, but it requires me to register as Apple developer. Should I do it?

Let me take a look at the S3 Resume and see if there are any changes I can make and test.

Let me run the test tonight and post the values.
