Product information

Description

The TP-Link TL-WN821N Network Card is a USB wireless adapter compatible with IEEE 802.11n (Draft 2.0), 802.11g and 802.11b standards. It supports Wi‑Fi 4 (802.11n) on the 2.4 GHz band and provides wireless transmission rates up to 300 Mbps. The compact USB device uses MIMO technology and internal intelligent antennas to improve throughput, stability and coverage while maintaining compatibility with other 11g and 11n devices.

Advantages

The adapter delivers up to 300 Mbps wireless speeds using MIMO, reduces channel interference with CCA channel selection, and supports secure setup via Quick Secure Setup (QSS/WPS). It includes broad encryption support (64/128‑bit WEP, WPA/WPA2, WPA‑PSK/WPA2‑PSK) and Roaming technology for more stable wireless connections. Simple configuration and monitoring are supported on Windows 2000/XP/Vista.

Suitable for

  • Upgrading a desktop or laptop to Wi‑Fi 4 (802.11n) on 2.4 GHz
  • Basic web browsing, email and file downloads

How to use

Insert the TL‑WN821N into an available USB port on your computer. Install the appropriate driver and utility supplied with the device or download the latest driver from the TP‑LINK website. Use the utility or the operating system network manager to select your 2.4 GHz wireless network and enter the network security key. For quick secure setup, press the QSS/WPS button on the adapter (or use the software equivalent) and then activate WPS on your router to establish a secured connection automatically.

Place the adapter where it has clear line‑of‑sight to the access point when possible, avoid large metal objects and dense walls to improve signal strength. Use WPA2 encryption where supported, and ensure your router firmware and adapter drivers are up to date for best performance and security.
