For some reason I lost network ability after letting LibreElect update itself to v10.x
I went right to the SMB and changed some settings but that didn't do it.
I then made a mistake to let it downgrade itself to 9.2.6 which corrupted something. I had to do a full, new, reinstall of 9.2.6.
10 just doesn't seem to work.
I use IBM Lenovo mini pcs for my players. They have i5's in them with 512ram and 256 gig ssds
