If the AP is running 6.xx firmware and beyond, holding the pinhole button for 15+ seconds while powered will clear the APs configuration. Once it reconnects with your CloudTrax network, it will re-download the network configuration. This can fix certain issues that occur on APs, and is a worthwhile troubleshooting step to take if experiencing trouble on one AP specifically.
Note: If your AP model is the OM5P-AN, the pinhole reset hole in the casing does not have a functioning button. In this case you would need to skip ahead to re-flashing the firmware of the AP as outlined here: How to manually flash firmware on a CloudTrax-enabled access point
