Hi there
I am on 1803 and have a similar disconnecting issue.
When I run troubleshooter it comes back with the Adapter does not have a Valid IP Configuration, this error sometimes requires network resets along with clearing DNS cache and removing IP leases, however the troubleshooter fixes it and I can continue until the next occurrence.
I have disabled all power saving features for USB and the Adapter as that was my inital suspicion.
As with the OP I have also checked for newer drivers via control panel. Current driver is version 1030.11.503.2016 from the 26th October 2016 and is provided by Microsoft.
I will continue to check for alternatives in the mean time
Hope someone has an answer
Best

ok so Christmas brain still in effect, I have been to the webpage and downloaded the November 2018 driver from the site, it's still installed a driver from 11 Sept 2017 though version 1030.22.405.2017
Adapter is V2.0 just in case, only bought it last week.
Cheers
