BrotherMFC-670CD Remote Setup Port (COM3) Driver

The BrotherMFC-670CD Remote Setup Port (COM3) driver helps Windows recognize the communication port used by Brother’s Remote Setup software to access device settings. It is intended for users setting up a Brother MFC-670CD or troubleshooting a missing remote setup connection, rather than replacing the device’s printing or scanning drivers.

Key Features

• Remote setup communication: Supports the connection between compatible Brother configuration software and the device’s remote setup interface.
• Port recognition: Helps Windows identify the Remote Setup Port entry, shown here as COM3. The assigned port number may differ between computers.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; check the individual package for supported editions and system architecture.
• Targeted troubleshooting: Installing the appropriate driver may resolve recognition problems caused by a missing or incompatible port driver. It will not necessarily fix unrelated printing, scanning, or connection issues.

How to Install BrotherMFC-670CD Remote Setup Port (COM3) Driver

1. Check your Windows version. Open your system information and confirm whether Windows is 32-bit or 64-bit. When checking Windows 10/11 compatibility, note that Windows 11 is not included in the supplied support list.
2. Choose a compatible package. Before starting your BrotherMFC-670CD Remote Setup Port (COM3) driver download for Windows, verify that the package explicitly supports your device and operating system. Select the latest version compatible with your setup, not simply the newest Brother driver available.
3. Download from a trusted source. Prefer Brother’s official support resources when available. A free download should not require a paid driver-updater subscription; avoid unrelated utilities bundled with third-party installers.
4. Install the driver. Extract the downloaded files if necessary, then follow the included installation instructions. If the package provides a setup program, run it and connect the device when prompted. Use Device Manager for manual installation only when the package instructions recommend it.
5. Verify the connection. Restart Windows if requested, check Device Manager for warning icons, and open compatible Brother Remote Setup software to confirm that it can communicate with the device.

Keep the driver updated when Brother provides a compatible update or when troubleshooting a specific issue. Although this entry may appear under Camera in a download catalog, its name identifies a remote setup port—not a webcam driver—so always match the package to the actual device before installing.

Common Issues and Fixes

• Install fails or rolls back: Disconnect the printer, uninstall existing Brother MFL-Pro Suite/Remote Setup Port entries in Apps & Features and Device Manager, reboot, then run the MFC-670CD installer as administrator. Use the exact MFC-670CD package, not a generic or Windows Update driver.
• Remote Setup can’t find COM3 / device not detected: Power on the MFC-670CD and connect USB directly, not through a hub. Check Device Manager under Ports for “Brother MFC-670CD Remote Setup Port (COM3).” If missing, reinstall the Brother port driver; if COM3 is used by Bluetooth or another serial device, free or reassign that port.
• Version conflicts or repeated COM3 errors: Remove older Brother software and duplicate COM port entries, reboot, then reinstall the compatible Brother package for your Windows version. Don’t mix Windows Update and Brother installers; if needed, run the Brother installer in compatibility mode.
