So I got done not to long ago building my first gaming pc and I downloaded windows 10. But my pc won't connect to the internet and I do have a ethernet cable pluged into my pc from my router and it still will not connect to the internet. It says windows could not find driver software for your device...if you know the manufacturer of your device download their driver. Also in the device manager and the pics on the side have a ? and a yellow triangle with an ! in the middle. I don't know if that means that it didn't install correctly. I have no idea why its not working will someone please help me.
