Do not rely on the "JP1082" label. Windows may fail to auto-detect it.
How to check (Windows):
VID/PID like:
A: Use the Davicom DM9621 driver from the official website – ignore the CD label. The “No 030818” is just a manufacturing code. jp1082 no 030818 usb lan driver
Issue: "Unidentified Network" or "No Internet Access"
Issue: Driver Install Fails / Code 10 Error Do not rely on the "JP1082" label
To avoid losing the driver for “jp1082 no 030818”:
Alternatively, use Double Driver (freeware) to export the specific .inf and .sys files. Right-click the unknown device → Properties → Details
The label "JP1082" refers to the PCB board design, not necessarily the chip inside. However, based on the model number and date code (030818), this adapter almost certainly utilizes the CoreChip Semiconductor RD9700 chipset.
This was a very popular generic chipset for USB 2.0 to Fast Ethernet (10/100) adapters.
If you cannot find a working driver after trying ASIX AX88772 and Realtek RTL8152, the JP1082 No 030818 may be a very old or non-standard chip. In that case, a new USB Ethernet adapter (e.g., Cable Matters, Plugable, or TP-Link UE200) costs ~$10–15 and saves time.
