W97L 1200M Wireless Bluetooth Network Card USB 3.0 Adapter Dual Band 2.4G 5G WiFi ac

This W97L-5DB wireless network card offers a convenient way to add both high-speed WiFi and Bluetooth connectivity to desktop or laptop computers that lack built-in wireless support. By using a single USB 3.0 interface, it eliminates the need for multiple adapters or internal card installation, making it ideal for upgrading older machines or expanding connectivity options in compact systems. The dual-band design covers 2.4GHz and 5GHz frequencies, ensuring broad compatibility with modern routers and reducing interference in crowded wireless environments. With support for IEEE 802.11b/g/n/ac standards and Bluetooth 4.1, this adapter handles everyday internet browsing, streaming, and peripheral connections without requiring additional hardware.

Features and Construction

This adapter combines WiFi and Bluetooth functionality into one compact unit using a USB 3.0 interface for faster data throughput. Its construction focuses on reliable connectivity across multiple operating systems and environmental conditions.

Dual-Band WiFi Performance

The W97L-5DB operates on the 2.4GHz band (2.4-2.4835GHz) and 5GHz band (5.1-5.825GHz), allowing users to select the best frequency for their network conditions. It supports the 802.11b/g/n/ac standards, enabling connection to both older routers and modern ac-compatible access points. Modulation methods include OFDM, CCK, QPSK, and BPSK for stable data transmission.

Integrated Bluetooth 4.1

Built-in Bluetooth 4.1 provides wireless connectivity for peripherals such as mice, keyboards, headsets, and speakers. This reduces the need for separate Bluetooth dongles and keeps USB ports free for other devices. The Bluetooth functionality works alongside the WiFi connection without significant interference.

USB 3.0 Interface

The adapter uses a USB 3.0 interface with 5.0V working voltage, offering faster data transfer speeds compared to older USB 2.0 designs. It remains backward compatible with USB 2.0 ports, so it can be used in systems without USB 3.0 support.

Compatibility and Security

This network card is designed to work across a wide range of operating systems and includes standard encryption protocols to secure wireless connections.

Operating System Support

Drivers are available for Windows XP, Vista, 7, 8, 10, Linux, and Android operating systems, making it suitable for many desktop and laptop configurations. Users should install the appropriate driver for their OS before first use.

Wireless Security Features

The adapter supports 64/128 bit WEP data encryption and WPA-PSK/WPA2-PSK along with WPA/WPA2 security mechanisms. These ensure that wireless communication can be secured against unauthorised access when used with a compatible router.

Environmental Tolerance

The unit operates reliably in temperatures from -10°C to 70°C and humidity levels of 10% to 90% RH non-condensing. Storage conditions extend from -45°C to 135°C with 5% to 90% RH non-condensing, allowing safe storage in various environments.

Benefits and Practical Use

This single-device solution simplifies adding wireless capabilities to any compatible computer, offering flexibility for different use cases and reducing desk clutter.

Simple Installation

The USB form factor requires no opening of the computer case or handling of internal components. Users simply plug the adapter into an available USB port, install the driver, and connect to a WiFi network or Bluetooth device.

Versatile Connectivity

Dual-band WiFi supports both 2.4GHz for longer range through walls and 5GHz for faster speeds in the same room. Bluetooth 4.1 allows connection of multiple peripherals simultaneously, turning a wired-only desktop into a wireless-capable system.

Value for Upgrades

For older computers or laptops with failing wireless hardware, this adapter provides an affordable upgrade path without replacing the entire system. Its USB interface means it can be moved between devices as needed.
