Missing radio interfaces on EAP615-Wall
Looking through my controller UI recently, I noticed that no client devices were connecting to one of my EAPs (EAP615-Wall). When I reviewed the its configuration, I noticed that neither radio had a channel configured. So I logged into the device via SSH and ran ifconfig, but it only showed eth0, lo, and br0 interfaces. The ra0 and rax0 interfaces were missing!? Restarting, resetting, running standalone, downgrading, upgrading, switching POE ports/switches... all did nothing. It seems like a hardware issue, but why would this happen all of a sudden? The device was fairly cool to the touch (unlike my other 615, which was warm), so I'm at a loss as to what happened. Has anyone experienced this before and, if so, what did you do?
