Title: A Comprehensive Review of the CH9200 USB Ethernet Adapter Driver: Top Download for Windows 10

Issue 3: Driver installs but speed is only 10 Mbps

Cause: Power management or cable quality. Solution:

Right-click the Windows Start button and click on Device Manager.

• In Device Manager → Network adapters → Right-click CH9200 → Properties → Advanced tab → Set "Speed & Duplex" to "100 Mbps Full Duplex" (not Auto Negotiation).
• Go to Power Management tab → Uncheck "Allow the computer to turn off this device".

| Issue | Solution | |-------|----------| | Driver installs but adapter not working | Uninstall device from Device Manager → Scan for hardware changes → Reinstall driver. | | Code 52 (unsigned driver) | Disable driver signature enforcement (see tip above). | | No link light / no network | Check cable, router port, and try a different USB port. |
