The D-Link DWA-172 Wireless AC600 Dual Band USB Adapter with Signal Plus adds wireless connectivity to a compatible 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. When downloading a driver for Windows 11, 10, 8, or 7, check that the package matches your operating system and the adapter’s hardware revision.

Key Features

• Windows device recognition: Provides the software interface needed for the adapter to appear correctly in Device Manager and work with Windows network settings.
• Dual-band Wi-Fi access: Enables connections to compatible 2.4 GHz and 5 GHz networks, giving you a choice based on coverage, interference, and router capabilities.
• Wireless AC connectivity: Supports the adapter’s AC600-class wireless functionality when used with a compatible router. Actual performance depends on signal strength, network traffic, and your setup.
• Connection management: Works with Windows Wi-Fi controls to scan for available networks, establish connections, and manage wireless access.

How to Install

1. Check your adapter and Windows version. Look for the hardware revision on the device label, then confirm which Windows edition and system type your PC uses. Driver compatibility can vary between hardware revisions.

1. Download the matching driver package. Choose a D-Link DWA-172 driver intended for your hardware revision and Windows 11, 10, 8, or 7, as applicable. Check the package’s compatibility notes rather than assuming one download supports every version.

1. Extract and run the installer. If the download is compressed, extract its contents first. Open the setup program and approve the Windows permission prompt if requested. Follow any instructions about when to plug in the USB adapter.

1. Complete the installation. Allow setup to finish, then restart your computer if prompted. If the package has no installer, open Device Manager, select the adapter or unidentified network device, choose Update driver, and browse to the extracted driver folder.

1. Connect and verify. Plug the adapter directly into an available USB port if it is not already connected. Use the Windows network menu to select your Wi-Fi network and enter its password. If no networks appear, check Device Manager for a warning icon and confirm that you installed the correct driver.

Common Issues and Fixes

• Install fails or stalls: Download the DWA-172 driver package matching your Windows version and hardware revision, run it as administrator, and temporarily disable antivirus. Unplug the USB adapter during setup, then reconnect when prompted.
• Adapter not detected: Plug it directly into a rear USB port instead of a hub. Check Device Manager for unknown devices or network adapters, update USB/chipset drivers, and reinstall the D-Link driver.
• Version conflicts or dropped connections: Uninstall older D-Link utilities/drivers, remove the device in Device Manager, reboot, and install the latest package. Use Windows wireless management to avoid utility conflicts, and test both 2.4 GHz and 5 GHz bands.
