I've got an R510 AP that I believe is stuck in boot loop. I have 2 AP's and both were working, and then I noticed that I've tried a few hard factory resets on it physically. I've unplugged and plugged it back up. I've changed ports on the switch. I've even switched ethernet cables to make sure the wire itself wasn't bad. I have a second AP that has no issues when resetting, but this one continues to have the red PWR indicator despite my different types of attempts to reset.
