I have a pc I built but it won't connect to the internet. I have an Asus Z170-a motherboard, and I'm not trying to use an usb or card you stick in for wifi. Im currently trying to use a Trend Net PowerLine AV 500 for ethernet. I have 1 box in a socket with the ethernet connected to my routher. The other box behind my computer and the ethernet plug into the mobo. No matter what I do it won't connect. I have never had wifi on this computer btw.
