The Software (Skylarc or the older Librarian) has nothing to do with the SDR/AMP
I also used the new SDRx with Librarian and now with Skylarc without any problems. I would check all connections first and ensure that the white led on the SDRx is on after booting of the CHIP mini pc.
PS: What is that wifi issue anyone talks about? Wifi works fine in client mode (Connected to my home wifi) for me
