The ASUS PCE-AC88 is a strong and powerfull card with a little flaw:
The driverpackage that Asus provides is Version 2.8.0.7Â from 2018/04/13 [link]
The driver in this package is version 1.558.48.8 from 2016/09/06
The device-name im device-manager with this driver is “ASUS PCIE-AC88 802-11ac Network Adapter”
My Windows 10 (newest patch 2020/04/20) crashes randomly with this driver whenever the system is under heavy load (any heavy load, not only networking).
After some searching I found the Chip which this card uses. It is the Broadcom BCM4356 and I found a newer driver for this chip.
Because I hate installationpackages I repacked the driver so you can install it without bloadware
Broadcom BCM4356 Wireless LAN Driver (works for ASUS PCE-AC88): [link]
This driver had version 1.558.53.1 from 2017/10/22
After installation the device is not longer an “ASUS”. Now the device-manager sees it as “Broadcom 802.11ac Wireless PCIE Full Dongle Adapter”.
With this driver for me all crashes are gone!
