I've searched the forums for an explanation for this settings and didn't find anything definitive.
What I learned from the search is that it sometimes helps with connections that timeout due to "extensive data loss". And it helps in areas where the climate changes frequently..
Here's the description from the manual:
periodic-calibration (default | disabled | enabled; default: default) - to ensure performance of chipset over temperature and environmental changes, the software performs periodic calibration
What exactly does it calibrate? And when this calibration takes effect do clients lose connection?
Thanks
