The D Link Wireless 108G DWA 120 USB Adapter connects a desktop or laptop to a wireless network through a USB port. Its driver allows Windows to recognize the D-Link adapter and manage wireless communication, helping you scan for available networks and connect without an Ethernet cable.

Key Features

• USB adapter recognition: Provides the device-specific software Windows needs to identify and use the DWA 120 as a wireless network adapter.
• Wireless network access: Enables communication between the adapter and Windows networking components so you can find and join compatible Wi-Fi networks.
• Connection management: Works with Windows network settings to establish and manage a wireless connection.
• Troubleshooting support: Installing the appropriate driver can resolve missing-driver warnings or an adapter appearing as an unknown device in Device Manager. It will not correct every connection issue, such as weak signal or incompatible router settings.

How to Install

1. Check your adapter and Windows version. Confirm that the label identifies your device as the DWA 120, and note any hardware revision. For Windows 11, 10, 8, or 7, verify that the driver package explicitly supports your operating system and system architecture. Older adapter packages may not support every Windows version.
2. Download the matching driver. Choose a package intended for this exact D-Link model and hardware revision. If the computer has no internet access, download it on another device and transfer it using a USB drive.
3. Extract and run the installer. Unzip the download if necessary, then launch the setup program. Follow its instructions about when to plug in the adapter. Administrator permission may be required.
4. Use Device Manager if no installer is included. Connect the adapter, locate it under Network adapters or Other devices, and select Update driver. Choose Browse my computer for drivers, then point Windows to the extracted folder.
5. Restart if prompted and test the connection. Open Windows network settings, select a compatible wireless network, and enter its password. If the adapter remains unavailable, check Device Manager for an error and confirm that the installed driver matches your hardware.

Use only a driver package with confirmed compatibility; a similar model name is not a reliable substitute.

Common Issues and Fixes

• Install fails or rolls back: The DWA-120 uses legacy 802.11g drivers. Run the installer as administrator, try Windows compatibility mode for XP/Vista/7, and disable driver signature enforcement temporarily if Windows blocks the unsigned package. Reboot before retrying.
• Adapter not detected: Check Device Manager for “Unknown Device” or a yellow warning. Plug the DWA-120 directly into a rear USB 2.0 port, avoid hubs, remove other USB wireless adapters, then uninstall the device and rescan for hardware.
• Version/utility conflicts: Remove older D-Link drivers and the D-Link WLAN utility before installing another driver version. Don’t run the D-Link utility and Windows WLAN AutoConfig together. Match the driver to the adapter’s hardware revision.
