Update 1903 cannot be removed as it does not show in the windows update list. Checked power options and disabled control of the device.Updated chipset and WLAN drivers loaded from HP (see ).Removed/Uninstalled the device completely and reinstalled (with reboot).Updated the driver with Windows update latest driver.I have disabled and re-enabled the adapter.No one can tell me how long this has been running this way and why. One detail: The laptop has been stationary for a long time and been using a wired connection. It sees wireless networks and just turns off, no exclamation mark or what so-ever. The issue I am seeing is that the WiFi turns off within 5 seconds after turning it on. HP EliteBook 850 G2 Notebook PC with Windows 10 on it.
