WR44 intermittent power-cycle

Hi

I have a WR44 that keeps power-cycling. It’s the second unit I’ve tried. I suspect it’s related to fluctuating 4G signal quality but I’ve never had this happen before (that I know of). I believe I’ve configured the unit not to power-cycle (under interfaces>Mobile>Advanced - If registration is lost for 5 minutes=Do not reset the module).
Please can you advise how I can stop the unit power-cycling regardless of signal quality?

Thanks
