I recently purchased a used PepWave AP One. I did a factory reset on it, did the basic network config and then went to register it’s serial number with my InControl so I could push out the config. When I entered the serial number for the device, Ireceived the message that teh Device was already registered. I assume this is, of course, because it was in use by the previous owner. How do I deregister this device so I can register it on my network?
