## Long description

Yealink WF40 is a compact wireless USB adapter that provides WLAN connectivity up to 150 Mbit/s and supports Wi‑Fi 4 (802.11n). Designed to add wireless capability via a USB port, the WF40 enables devices without built‑in Wi‑Fi — such as desktop PCs or compatible IP phones — to connect to wireless networks for web browsing, email, streaming and basic network access. The adapter is finished in black and uses low power consumption to suit continuous office or home use.
Advantages
The WF40 offers straightforward plug‑and‑play operation and a small form factor that keeps the USB port unobstructed. With support for IEEE 802.11n and backward compatibility with 802.11b/g, the adapter provides a reliable connection and up to 150 Mbit/s transmission rate suitable for standard office tasks. Its low power profile is intended to minimize impact on host devices while maintaining stable wireless connectivity for IP phones and computers.
Suitable for
Adding Wi‑Fi to desktops or laptops without built‑in wireless
Connecting compatible IP phones to an office Wi‑Fi network
Basic web browsing, email and media streaming in home or small office environments
Temporary or portable wireless setups where a small USB adapter is preferred

How to use
Insert the WF40 into an available USB port on a compatible device and allow the operating system to detect and install any required drivers automatically if supported. If drivers are not installed automatically, download the appropriate driver from the device or manufacturer support page and follow the installation instructions. After installation, use the system network settings to select the desired Wi‑Fi network and enter the network credentials to establish a connection.
Usage recommendations
Place the adapter in a USB port with good line‑of‑sight to the wireless router for best signal strength. For sustained performance on IP phones or workstations, use a direct rear or side USB port rather than a hub, and ensure the device firmware and drivers are up to date.
