The Dell Wireless 1704 Bluetooth v4.0 HS driver enables Windows to communicate with the Bluetooth hardware in compatible Dell computers. It supports device discovery, pairing, and wireless connections with accessories such as mice, keyboards, headsets, and phones. Before downloading, confirm that the package matches your computer and Windows version, particularly if you have upgraded from an older operating system.

Key Features

• Bluetooth device recognition: Helps Windows identify the Dell Bluetooth adapter and make its functions available through system settings.
• Accessory pairing and connectivity: Provides the software needed to discover and connect compatible Bluetooth peripherals without a separate USB receiver.
• Bluetooth 4.0 functionality: Enables supported features of the adapter, including low-energy communication where the driver, operating system, and connected device allow it.
• Connection troubleshooting: Installing a suitable driver can help resolve missing Bluetooth controls, adapter detection problems, or pairing issues caused by outdated or damaged driver files.

How to Install

1. Check your hardware and Windows version. Open Device Manager and look under Bluetooth or Other devices for the adapter. Confirm whether your PC uses Windows 11, 10, 8, or 7, and check whether the system is 32-bit or 64-bit.

1. Choose a compatible driver package. Match the download to the Dell Wireless 1704 Bluetooth v4.0 HS and your specific Dell computer model. Compatibility can vary between packages; an older release should not be assumed to support Windows 10 or Windows 11 simply because it installs.

1. Run the installer. Extract the downloaded archive if necessary, then launch the setup program with administrator permissions. Follow the prompts and allow Windows to install the Bluetooth components. If the package contains only driver files, use Device Manager’s Update driver option and browse to the extracted folder.

1. Restart your computer. Save your work and reboot when installation finishes. Make sure airplane mode is off and Bluetooth is enabled in Windows settings or through your computer’s wireless controls.

1. Test a Bluetooth connection. Put an accessory into pairing mode, add it through Windows Bluetooth settings, and verify that it works. If Bluetooth remains unavailable, check Device Manager for warning icons and confirm that the installed package supports your hardware and operating system.

Common Issues and Fixes

• Installer fails or stalls: Uninstall any existing Bluetooth/Broadcom driver, reboot, enable the Bluetooth radio (Fn key/airplane mode off), then run the Dell Wireless 1704 package as administrator.
• Device not detected: Check Device Manager for hidden/disabled entries, confirm Bluetooth is enabled in BIOS/UEFI, and disable USB selective suspend for the Bluetooth adapter.
• Version conflicts after Windows Update: Windows may replace the Dell driver with a generic Bluetooth stack. Roll back to the Dell Wireless 1704 driver in Device Manager, or temporarily pause automatic driver updates while reinstalling.
