Only the red light is on. Have tried a known good new cable as well as the reset proceedure noted in other posts. (push reset button while connecting power and hold for at least 10 seconds) I have two AP in my home, one is working fine and the other is not. I called the helpdesk too and was told: AP will not boot successfully, attempted power down and default. Do I need to send this in to be repaired/replaced? Thanks, Kevin
