TP-LINK TL-WN821N single-pair average downlink rate of 59.1Mbps, a pair of average uplink rate of 57.2Mbps, the two test results in the 300M wireless card in the upper level, the overall performance is quite satisfactory. TP- LINK TL-WN821N very cost-effective, absolutely the average home user's best choice.

TP-LINK TL-WN821N wireless NIC Built-in two smart antennas, while supporting MIMO technology, transmission signal stability, the maximum speed can reach 300Mbps, suitable for high demand on the network of consumers to buy.

TL-WN821N It has the priority service function to ensure the priority processing of bandwidth sensitive data such as video and voice so that the user can make smooth video call and other activities to ensure that the important tasks are not affected.This product has QSS fast security encryption key, use this button It encrypts and encrypts network signals through WPS protocol. It also supports 64/128/152-bit WEP encryption, WPA / WPA2, WPA-PSK / WPA2-PSK and other advanced encryption and security mechanisms to protect the network in a variety of ways. Safety.

Robust wireless performance

TL-WN821N uses 11N wireless technology, wireless transmission rate up to 300Mbps. Compared to the traditional 54Mbps 11G products and 150M products, with higher wireless bandwidth, LAN data transmission more efficient, can effectively reduce network latency, so that Voice and video, online games, on-demand more smoothly.

The TL-WN821N uses a 2 × 2 MIMO (Multiple Input Multiple Output) architecture with two Smart Antennas. The TL-WN821N enhances its wireless reception capability and enhances the stability of the wireless signal.

The TL-WN821N also uses the CCA (Clear Channel Assessment) channel detection technology to automatically adjust the bandwidth mode to avoid channel interference and make the wireless signal more stable when the surrounding wireless signal interference is detected.When the interference disappears, But also automatically **** free channel, make full use of the advantages of channel **** to enhance wireless performance.

All-round security

The TL-WN821N supports WPA-PSK / WPA2-PSK, WPA / WPA2 security, and WEP encryption to protect the wireless network from infringement and misappropriation.

The TL-WN821N is equipped with a QSS quick security setting for the QSS or WPS, and the QSS Fast Security button on the wireless router and network card, or by entering the router's PIN code, you can complete than the traditional WEP encryption more secure WPA2 wireless security connection, do not need to remember the complex password.
