bob2kids You  can install the intel driver if you are having issues with the Dell driver. Uninstall the dell driver and  reboot the computer. You can then install the intel drivers.
I have a Dell XPS 8920 with a Intel Dual Band Wireless AC 3165.  The existing driver is 19.1.0.4. ( I don't know the driver number when I received the machine in beginning of May 2017 because as you read below, it was reset.)  When I installed Dell support new driver 19.20.0.6, I get a blue screen with message "Driver IRQL not less or equal"  "What Failed: Netwtw04.sys".  The PC then periodically starts up OK and other times I get the same blue screen again before starting up OK.  A dell support person reset my driver to 19.1.0.4 and no blue screen.  The intel website has latest driver as 19.60.0.  Why is the Dell driver giving me problems?  Should I upgrade to the Intel driver?  Thanks...bob
