Hi, last week I was having an issue where my APs turn them self off (no lights on any of them). I rebooted the router and went into unleash, updated the firmware to the latest version per instruction on this forum but the problem still persist. After router reboot, the APs come online for about an hour then go offline. I have two r510 and they both go off at the same time. I have double checked each of them and they currently have the 200.15.6.12.304 firmware. Please help.
