If the ASIX driver refuses to install (error code 10 or 52), you can use a community-maintained wrapper: the NDIS 6.0 shim for MCS7830 chips.
Steps:
This method works but yields only 10/100 Mbps speeds (no gigabit). Suitable for legacy printers, IP cameras, or IoT devices—not gaming or large file transfers.
A: Windows 11's updated driver security blocks the manufacturer's unsigned INF file. The OS sees the USB Vendor ID (VID) but cannot match it to a certified driver, so it displays the internal chipset marker "i---". i--- Driver Usb To Lan Qts1081b Windows 11
A: That is the Corechip RD9700. Use the "RD9700 Windows 11 driver." The "i---" label often applies to this specific chipset.
Windows 11 has much stricter driver security policies than Windows 10 or 7. The generic drivers that shipped with the QTS1081B are often unsigned or use an old signature algorithm (SHA-1 vs. SHA-2). Consequently, Windows 11 blocks them automatically, leaving you with the cryptic "i---" entry.
When you plug a QTS1081B adapter into a Windows 11 PC, the OS often labels the device simply as "i---" or "i--- Network Adapter" . This is a placeholder name stemming from the chipset manufacturer's ID string. In most cases, the "i---" refers to a chipset manufactured by Corechip (often the SR9900 or similar) or a Realtek clone. If the ASIX driver refuses to install (error
Never download "Driver Booster," "Driver Easy," or generic EXE installers from pop-up ads. They will install malware or adware. Stick to *.inf manual installs or verified OEM archives.
After installation:
Struggling with an "i---" brand USB to Ethernet adapter on Windows 11? You are not alone. This method works but yields only 10/100 Mbps
Many users purchase budget-friendly USB to LAN adapters labeled with brands like i-tek, i-technology, or generic "i---" models. These often feature the QTS1081B chipset. While Windows 11 usually handles drivers automatically, this specific chip sometimes requires a manual fix to avoid limited connectivity, blue screens, or the dreaded "Code 31" error.
