Everything has been working as before with the new cards. All peripheral connected to the duet was functional as before the malfunction. I have reduced the PSU voltage from 25.8V to 24.1V to be within specifications. I'm also monitoring the min/max voltages reported by the duet every now and then. I also installed a WIFI repeater close to the duet, since there is a thick floor between the router and the duet to improve the signal strength.
