Vostro 3670, update issue, wrong wireless/bluetooth update

Dell Wireless 1707/Qualcomm 9565 WiFi and Bluetooth Driver

The version on the Support site dates from 01/01/2019

Dell Update software insists as "Urgent" to install a driver from the middle of 2018.

If you run the Dell Update install, it not only fails partway through (the Dell Update instance just "goes away", without telling you whether it crashed, finished, etc), you end up getting BSOD crashes (DPC Watchdog Violations) afterward while it still keeps telling you you need the update every few days.

Attempts to reinstall/repair fail (including downloading the more recent version), unless you remove the driver completely and reinstall from scratch with the Jan 2019 version.
