@timidtinkerer the USB socket is device only and USB dongles need to work with a USB host. The easiest way ti sot get a Ethernet-Wifi bridge. there are lots of them out there and infact thats how we made the old first generation Duets wireless, see this older blog post about using a TP-Link
@dc42 so I solved it I had the positive and negative wire from the psu plugged into the opposite screws. Haven't rewired it to see if there's permanent damage will report back to keep it effects documented (this is my walk of shame)
