The JP1082 030818 is a "get-out-of-jail-free" card for emergency networking. While the driver hunt is frustrating, the SR9700 chipset is widely documented. Once the driver is verified and installed, it is a stable, albeit slow, solution for basic web browsing and diagnostics.
For macOS, the JP1082 with SR9900 performs poorly. If you have a Mac, check your adapter's chipset. If it's SR9900, replace it with an ASIX-based adapter. jp1082 no 030818 usb lan driver verified
