Link light not on, nor flashing
I have a Cisco DPC 3010 cable modem(installed by Cox 6/7/2012) and a D-Link DIR615 Router connected to an IMac (late 2010). Yesterday I noticed that the link light on the modem was not blinking--no light at all. As far as I call tell, all the functions of the computer have not been affected--everything seems normal. Is there a problem? Could the linkLED be burned out? Advice, suggestions?
