It looks like after Sleep mode device initialized differently then after reboot or power on (firmware bug). I did that and got duplicated device instance after reboot/poweron, so it's not a solution. What SSD resource are you trying to 'save' in Sleep mode?" "As a test, delete both instances of the adapter after you come out of sleep, scan for hardware changes, and check if you get only one instance and whether it work properly. 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. As a result you always have annoying problem with wi-fi network connection after sleep mode until reboot. 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. This is because failed adapter firmware initialization on S3 resume.Ĥ. Now you can see another detected (duplicated) "Network Adapter" device instance as active, but the first one becomes inactive.
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.
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.ģ. Using Device Manager completely uninstall Broadcom 802.11ac network driver with option "Delete the driver software for the device".Ģ. Seems to be there is a serious bug in BCM43xx adapter firmware (MacBook Pro ) resulting in failed S3 resume initialization (wake-up from Sleep) under Windows 10.ġ.
