Hi David,I'm not a pro or anything but I had my share of issues with this WLAN card and everything I tried - end up the same.I gave up of trying to work with this card, as I upgraded my internet at home I replaced the card and upgraded my laptop as well to the Intel AX200. After the upgrade all of issues just gone. Hope this helps somewhat
I'm dealing with a peculiar problem with my wife's Inspiron 15 5593 laptop.  Her system froze, and I wound up having to reinstall Windows 10 after attempting to fix startup and resetting the PC didn't work. I downloaded the recovery image (based on Windows 10 1809 version) from the Dell website to a USB key, ran the recovery to install that image, and the laptop froze during boot of the installed image at setting up devices - disabling (in BIOS) the Qualcomm WiFi/Bluetooth adapter (QCA61x4A-QCA9377) and restarting the recovery image install resulted in a successful install and boot.  Once that image was up and running, enabling WiFi (in BIOS) and rebooting did not cause problems (I left Bluetooth disabled, as it's not used) ... until Windows installed the Windows 10 update to the 20H2 version of Windows - after restarting, the laptop froze while installing changes.  Disabling WiFi (in BIOS) and trying that 20H2 update again worked. So, now on Windows 10 20H2, enabling WiFi (in BIOS), booting Windows and attempting to install the latest Qualcomm driver for this system from Dell freezes the laptop during the driver install.  Turning the laptop off and restarting results in a freeze at the picture before the login screen or at the login screen (I suspect that this is Windows installing that driver behind the scenes).  Everything works fine with WiFi disabled in BIOS.  I suspect a hardware problem, but the fact that things seem to work with the 1809 version of Windows but not the 20H2 version is peculiar.  Does anyone have any insight into what's actually going on? Thanks, --David
