The D-Link DWA-140 RangeBooster N USB Adapter (rev.B2) adds wireless network connectivity to a Windows PC through a USB port. Its driver allows Windows to recognize the adapter and communicate with it so you can find nearby Wi-Fi networks and connect to your router. Before downloading, check that the package matches hardware revision B2 and your Windows version.

Key Features

• USB wireless adapter recognition: Provides the software interface Windows needs to identify and use the DWA-140 rev.B2 as a network adapter.
• Wireless-N connectivity: Enables the adapter’s supported Wi-Fi functions for everyday browsing, email, and other network activities. Actual performance depends on your router, signal strength, and local interference.
• Network connection management: Works with compatible Windows networking tools to scan for available networks and establish a connection.
• Revision-specific setup: Using a driver intended for rev.B2 helps avoid compatibility problems caused by installing software for a different DWA-140 hardware revision.

How to Install

1. Confirm your adapter and operating system. Check the adapter’s label for the B2 hardware revision. Identify whether your PC runs Windows 11, 10, 8, or 7, and check its system type where applicable.

1. Choose a compatible driver package. Review the download’s listed operating systems and hardware revisions before proceeding. Do not assume an older package supports Windows 11 or Windows 10 unless compatibility is explicitly confirmed.

1. Extract and install the driver. If the download is compressed, extract it to a folder first. Run the included setup program and follow its prompts, connecting the USB adapter when instructed.

1. Use Device Manager if no installer is provided. Connect the adapter, open Device Manager, and locate it under Network adapters or Other devices. Right-click it, select Update driver, then choose Browse my computer for drivers and point Windows to the extracted folder.

1. Verify the connection. Restart the PC if prompted, then open the Windows Wi-Fi settings and connect to your network. If the adapter is missing or shows a warning in Device Manager, recheck the driver’s revision and OS compatibility before trying another USB port.

Common Issues and Fixes

• Install fails or rolls back: Use the Rev.B2-specific driver package, run the installer as administrator, and on Windows 10/11 try Compatibility Mode for Windows 7/8. Unplug the adapter until setup prompts, and temporarily disable driver signature enforcement if Windows blocks the older driver.
• Adapter not detected: Check Device Manager for an Unknown device or Ralink/D-Link entry. Try a rear USB 2.0 port directly—avoid hubs and USB 3.0 ports—then uninstall the failed entry, reboot, and replug. Confirm it is the Rev.B2 model.
• Version conflicts or dropouts: Remove older D-Link/Ralink drivers and utilities via Programs and Features, delete leftover Device Manager entries, reboot, then install only the Rev.B2 package. Avoid mixing Windows Update and vendor drivers.
