I have an Asus prime z390-a motherboard. I got an ethernet cable today and went to plug it in but had no connection. After trying everything else I had ruled out everything but the computer. That's when I noticed that my ethernet port would only light up if after I inserted the ethernet cable I pulled on it a little bit. It's working now but it seems to be very touchy where the slightest movement can cause it to become disconnected. Is there something I can do to fix this without sending it back for a replacement?
