Help! "The cable for Ethernet is not plugged in."

in Genius Bar edited January 2014

Today, I switched from a PC to a Mac.

My problem is that I cannot connect to the internet through Ethernet because System Preferences says "Cable Unplugged. The Cable for Ethernet is not plugged in."

It *is* plugged in. What is going on?

I use a Motorola SB5120 cable modem and Comcast service to connect to the internet. I also use a brand new Belkin RJ45 Male/Male ethernet cable to connect the computer to the cable modem.

    I would suggest you try another ethernet cable.. let us know if you still have issues.. you could also try unplugging both ends and switching them.. ensuring you hear a faint click and check to see if they are secure.
