I built up a PC and I'm having trouble connecting to the internet. I have a hard line from the PC to the modem. I see no flashing LEDs where the cable connects to the integrated port on the motherboard (MSI Z97 Gaming 5) and the modem. I tried using a different cable and I still get nothing. All I see on the monitor is "Not Connected--No Connection are available". How do I get the PC to detect the modem? any ideas? thanks.
