Broadcom 802.11n Windows 10 64bit Pro - BSOD - Hyper-V must be disabled or other driver
AS7560G-6344G50Mnkk
After Windows updated Broadcom driver BSOD has been real problem ( MEMORY MANAGEMENT , sometimes driver name related to this visible, bcmwl63a.sys )
Driver has some issues/conflict with Hyper-V.
Something to do with Hyper-V virtual Switch. So Hyper-V must be disabled.
From Windows Features: remove Hyper-V
or before that if after reboot still there: Ethernet connections find WLAN connection and remove
hyper-v protocol from adapter settings
or find better(older?) driver.
Or roll back driver in Device Manager.
Laptop works fine when no internet browsing happens, sometimes BSOD instantly at boot to desktop, sometimes internet browsing works for a while, then again even online games are working fluently for hours.
CMD: Scannow /fsc or Memory Checks do not give error.

Unfortunately Acer does not have control over Windows updates. But if this happened right after a Windows Update you can try uninstalling the Windows update for that driver and see if this resolves the issue. Instructions are posted here that may be helpful:

Hi again
Removing Hyper-V did not solve problem.
Laptop worked days without BSOD, but yesterday... BSOD. Even before Windows login screen !
>>>>> Problem solved by different driver, example like this: 6.30.223.256 <<<<<<
There were different error messages in BSOD screen.
MEMORY MANAGEMENT (Windows 10 Pro 64-bit, BSOD)
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (Windows 10 Pro 64-bit, BSOD)
PAGE_FAULT_IN_NONPAGED_AREA ( Windows 8.1 updated to Windows 10 PRO 64bit, BSOD)
and finally ones BSOD message with exact reason : ....bcmwl63a.sys
There are chat messages that people experience also slow/broken WLAN traffic.
In this PC it was not possible to downgrade driver to earlier one.
1. Install ex. 6.30.223.256 or other any earlier driver . This driver has caused some problem with other PCs but works fine with AS7560G-6344G50Mnkk.
2. It propably does not install to operate instantly, so remove then problematic 7.35.333.0 driver in Device manager.
3. I even removed also Broadcom 802.11n device itself so i scanned PC for changes
4. After finding Broadcom 802.11n system installed driver ver. 6.30.223.256.
All OK now.
There might be problem/conflict with 802.11n vs. 802.11ac part in Microsoft driver 7.35.333.0 ???
