Welcome to RAK forum @pchan :slight_smile:

It is weird that all your RAK811 WisNode are not working. Since you tried to connect it already to two different PC, could it be the USB cable?

Regarding J2, it is a jumper option to directly power the RAK811 module. But that is shorted by default so it shouldn’t matter.
