RJ45 Female supporting Fast Ethernet speeds (10/100 Mbps auto-negotiation) Underlying Chipset: Corechip RD9700 / SR9700 / JP1081 Hardware ID: USB\VID_0FE6&PID_9700 💾 Downloading the JP1081B USB LAN Driver
Plug in the adapter, then on Windows open Device Manager → Network adapters . Look for a name containing “AX88179”, “Realtek USB GbE”, etc. That’s your real chipset.
Reboot the machine and connect the adapter to a different physical USB port to force a clean system verification check. Address Hardware Identification Mismatches
, which often have generic drivers pre-installed or available via Windows Update
is a small USB-to-LAN adapter that converts a standard USB 2.0 port into an RJ45 Ethernet port. It supports 10/100 Mbps (Fast Ethernet). Interface: USB 2.0 (backward compatible with USB 1.1).
: Often cross-compatible with RD9700 , QF9700 , Corechip QTS1081B , or DM9601 drivers. Common Hardware ID : USB\VID_0FE6&PID_9700
The JP1081B (frequently labeled interchangeably as the QTS1081B or RD9700 adapter) is engineered around a legacy, cost-effective bus system. Because these generic devices are sold under dozens of unbranded names, checking your specific hardware identifier in the system parameters ensures you are installing the exact matching firmware.
This can be a power management issue. Go to Device Manager > Network Adapters > JP1081 > Properties > Power Management and uncheck "Allow the computer to turn off this device to save power." 6. Supported Operating Systems Windows 10 (32/64-bit) Windows 8 / 8.1 (32/64-bit) Windows 7 (32/64-bit) Windows Vista / XP Linux (using open-source DM9601 drivers) Conclusion The JP1081B USB LAN adapter
: Most users report success by letting Windows Update find the driver or manually selecting a compatible Realtek RTL8152B or Corechip driver in the Device Manager.
Always verify digital signatures for Windows .inf or .cat files.
Note the specific Vendor ID () and Product ID ( PID ) values (for example: USB\VID_050D&PID_047A ).
While many modern systems detect the adapter automatically, older or specific versions often require manual driver installation.
Because the JP1081B uses a legacy chipset architecture, modern operating systems may not pull the file automatically from Windows Update. Follow these steps to complete a manual installation. Step 1: Secure a Safe Driver File
