Wireless Dual Band PCI-E Network Adapter

Mac / PC / PCIe / 802.11n
Wireless speeds of up to 450Mb/s
Today's fastest wireless speeds
TP-LINK's 450Mb/s Wireless N Dual Band PCI Express Adapter, TL-WDN4800 allows you to connect a desktop computer to a wireless network and access a high-speed wireless network connection. Complying with IEEE 802.11a/b/g/n, the device can use the 2.4GHz or 5GHz channels and provide wireless speeds of up to 450Mb/s which is ideal for users seeking a highly robust, bandwidth intensive wireless networking experience, particularly with HD video streaming and online gaming.
Three antennas increase wireless performance and stability
Dual Band support - 2.4GHz or 5GHz channels bring an optimized HD video streaming, file sharing and online experience.
Dual Band
Dual Band is the latest wireless technology allowing the adapter to connect with a 2.4GHz or 5GHz network. This allows you to check e-mail and browse the Internet using the 2.4GHz band or stream HD movies and other media on the 5GHz band. The advantage of working on the 5GHz band is that, unlike the crowded 2.4GHz band shared with microwaves, cordless phones and other wireless networks, it has much less interference and can provide a more stable wireless signal, which is ideal for online gaming and HD video streaming.
WPA / WPA2 Encryptions - Advanced Security
Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols and security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks. WPA/WPA2 encryption standards ensure your wireless connection is safe from intruders.
Wireless N Speed up to 450Mb/s
Wireless N (802.11n) is a next generation high-speed Wi-Fi standard, capable of delivering the range and capacity to support today's most bandwidth-hungry applications, like streaming HD (High Definition) video, voice and music. Both the adapter's 2.4GHz and 5GHz bands support the maximum speed of up to 450Mb/s, which generates a maximum theoretical wireless throughput bringing you a limitless wireless experience.
Easy Operation
TL-WDN4800 comes with a CD utility that helps you complete the software installation and wireless network settings, including security configurations and wireless connection, which makes setting up your network so easy that even for novice users should be up and running in minutes.
