I just put together a computer with the MSI Z390I board with integrated Wifi.
I fought an issue where I could connect to the internet, but not play Overwatch or connect to Blizzard servers. I got DNS resolution errors, and event logs for tons of wifi device resets.
The solution was that the drivers were too new for this board. Download the chipset drivers directly from the motherboard manufacturer’s website, and do not use Intel’s or Windows’s auto driver update.
