Product information

Description

The Cudy WU1400 is a compact USB wireless network card that supports Wi‑Fi 5 (802.11ac) and dual‑band operation on 2.4 GHz and 5 GHz. It delivers up to 867 Mbit/s on the 5 GHz band while providing extended range on 2.4 GHz. The adapter features high‑gain antennas to improve signal sensitivity and penetration through walls and connects to PCs and laptops via USB. Compatible with Windows (7/8/8.1/10), macOS and Linux, the WU1400 is designed for higher‑speed internet, streaming and online gaming when an internal Wi‑Fi adapter is absent or underperforming.

Advantages

The dual‑band design gives flexibility between long‑range 2.4 GHz connections and high‑speed 5 GHz links reaching up to 867 Mbit/s. High‑gain antennas increase reception sensitivity for more reliable connections over longer distances and better wall penetration. USB power and a compact black housing make the card easy to install and transport. Broad OS support includes Windows, macOS and Linux.

Suitable for

  • Desktop PCs or laptops without a functioning internal Wi‑Fi adapter
  • Streaming HD video and online gaming on the 5 GHz band
  • General web browsing and devices requiring extended wireless range on 2.4 GHz

Key specifications

  • Model: Cudy WU1400
  • Wireless standard: IEEE 802.11ac (Wi‑Fi 5), also backward compatible with 802.11a/b/g/n
  • Dual‑band: 2.4 GHz and 5 GHz
  • Maximum data rate: 867 Mbit/s (5 GHz)
  • Interface: USB
  • Colour: Black

How to use

Plug the Cudy WU1400 into an available USB port on your computer. Install the appropriate drivers for your operating system if they do not install automatically. Place the adapter where the antennas have a clear line or good angle toward the router to improve reception. After driver installation, select the desired 2.4 GHz or 5 GHz network in your system’s Wi‑Fi settings and connect using your network credentials.

Usage recommendations

For the best performance while streaming or gaming, connect to the 5 GHz band and position the adapter to minimize obstructions. Use the 2.4 GHz band when you need greater range or better penetration through walls. Keep drivers updated for compatibility and performance improvements.
