What do the lights mean on the ethernet port on a gigabyte motherboard

[UndeadHacker]

I have a gigabyte motherboard in my pc I built about a year ago and yesterday I could not get my internet to work I played with my router and also tried rebooting my machine however none of this has worked. I took another look at the port today and found that there were two lights(which I have no idea what they mean). However I noticed an orange or red one was staying constant while a yellow one was blinking. Could someone explain the meaning of these lights or tell me if that could be my problem. Thanks

Orange steady light: Connection is at 1Gbs
Yellow flashing: Activity on port

Indicates a normal connection to the router. The problem is likely elsewhere.
