For several years TP-Link has been manufacturing network equipment. In this case it is wireless a WiFi network card compliant with the IEEE 802.11n standard (compatible with 802.11bgn).
It is connected to a computer via modern PCI-E x1 interface, which ensures compatibility with modern desktop computers.
The card supports the IEEE 802.11n wireless specification with a maximum throughput of up to 150 Mbps and is ideal for the most demanding users who want to wirelessly transfer large amounts of data quickly. The TL-WN781ND network card is even designed for file and multimedia sharing or data sharing. There is also support for WEP and WPA/WPA2 encryption.
The card is equipped with a 2dBi Omni antenna. The dimensions of the device are 120.8 x 78.5 x 21.5 mm. TL-WN781ND can easily establish connection with a wireless network and get up to 9 times higher transmission speed than conventional 11g products.
Compared to older products, this network card will provide you with improved performance, allowing you to surf more pleasantly, including file sharing and streaming media.
