My 2 access points went out all of a sudden. The switch and everything else is fine. I have read some great suggestions on ways to get them to light up again but that all involves me climbing up on a ladder, figuring out how to pull them down off my ceiling without breaking them or damaging the wall. I just want to find someone who can come out and help me see if they just need to be reset. I'm fine with buying new ones but not sure where to start. No sure what model replaced the R510. Can anyone suggest a tech in metro Atlanta?
