The driver provided by driver Booster 8.4 for a USB key architectured on Driver for Realtek 8811CU Wireless LAN for Wi-Fi 802.11ac (Wi-Fi 5) is not valid (not digitally signed).
A warning windows pop-up recommended to not install it and, after installed it, it doesn't work at all.
Windows Update does not find a more recent and genuine driver.
I found, downloaded and installed the most recent [win10_1030.38.0304.2019_Drv_3.00.0031_UI_1.00.0299.L] on Comfast web site clé USB CF-811AC
