Latest update broke Wi-fi!

Clearly they have not tested all the drivers and released a bad one. Perhaps they got that driver from the company and did not adequately test it.

updates may overwrite driver-related code elements, and thereby "break" the driver, or cause the device to disappear entirely from Device Manager.
You're right that an in-place upgrade repair install might help,

I was on a chat with MS Help, I got the ISO for 1809 v17763.1
Got cut off the chat just as it was finishing.
I want an MD5 or a SHAH before I proceed, someone got it somewhere?

BTW, I had to do
ipconfig /flushdns

to fix the problem of intermittent connectivity.

It happened again, lost wifi today December 18th, 2018.

MSI Titan GT80 SLI, was running 1803, just bumped me to 1809 half an hour ago. I thought for sure the driver issue was solved as it nuked my wi-fi ability in this October disaster as seen above. Well, no. The same thing happened. I quickly downloaded the drivers and installed them and I am back online. BTW the wifi site had newer drivers than the MSI page.

This is just a ridiculous situation, I should not have to install drivers when going from 1803 to 1809. They had weeks to debug this and haven't yet.

I don't much care about the under the hood processes, point is, with 1803 wifi worked and with 1809, it did not.

If you want to stop Windows update from updating any drivers, you could change the update policy to inhibit it from down loading and installing all drivers, but that's not going to alter a Feature update. Have you checked on the MSI forums for anybody else that may have a this similar problem ?
