## Long description

The Cudy WU5400 network card WLAN 2402 Mbit/s is a USB Type-A wireless adapter that upgrades desktop and laptop PCs to Wi‑Fi 6E capabilities. Supporting tri-band operation including the 6 GHz band, it delivers high theoretical throughput and reduced interference compared with previous Wi‑Fi generations. The adapter is finished in black and uses two external high‑gain antennas in a 2x2 configuration to improve signal reach and stability for demanding tasks such as gaming and high‑definition streaming.
Advantages
Tri‑band Wi‑Fi 6E support adds the 6 GHz frequency to traditional 2.4 GHz and 5 GHz bands, offering lower latency and less congestion where 6 GHz is available. External high‑gain antennas and a 2x2 spatial stream design increase reception and throughput consistency. The USB 3.0 interface enables higher host transfer rates and backward compatibility with USB 2.0 ports. Built‑in driver support and plug‑and‑play behavior on supported Windows versions simplify installation and setup.
Suitable for
Online and competitive gaming requiring low latency and stable connections
4K/8K video streaming and concurrent multimedia playback
Video conferencing and large file transfers over a home or office network
Upgrading older PCs without integrated Wi‑Fi 6/6E support
Key specifications
Connectivity technology: Wireless (Wi‑Fi 6E/802.11ax compatible)
Interface: USB Type‑A (USB 3.0 recommended for full throughput)
Maximum data transfer rate: up to 2402 Mbit/s on compatible bands
Frequency bands: 2.4 GHz, 5 GHz and 6 GHz (tri‑band operation)
Antenna configuration: External 2x2 high‑gain antennas
Color: Black
How to use
Insert the Cudy WU5400 into an available USB Type‑A port on a Windows 10/11 PC. On first connection, the adapter will attempt to install drivers automatically; follow on‑screen prompts if any additional permissions are requested. Position the external antennas vertically for general use or adjust their angle for improved reception toward your wireless router. Select the appropriate SSID and authentication method in Windows network settings to connect to your Wi‑Fi network. For best performance, use a USB 3.0 port and ensure your router supports Wi‑Fi 6E when accessing the 6 GHz band.
Usage recommendations
Place the adapter where it has a clear line of sight to the router and avoid placing it behind large metal objects. Use the 6 GHz band for latency‑sensitive applications such as competitive gaming when your environment and router support it. Keep router firmware and host drivers up to date to maintain optimal throughput and security.
