So here's the situation I just built a new PC with MOBO with integrated network card but no wifi. I thought it's ok I'll just connect to it with cable. I have a modem connected to router, I took out the cable from router and plugged it into PC just to see if I have connection. It didn't work 1 led on lan port on my PC was light up orange all the time and 2nd led was lighting on and off orange and I had no internet connection some suggestions what is the problem?
