My computer looses connection to the internet randomly, it will go on and off for about a minute and then go back to normal for the night or even 2 to 3 days. When it does that, the windows diagnostic says "please connect an ethernet cable". I upgraded my motherboard killer network drivers. It's an MSI Gaming 5 z97. What should I troubleshoot next? It is so random. It does not happen to other devices in the house (other computers and phones).
