TP-LINK TL-WDN4800

A high quality Wi-Fi card from TP-Link that supports speeds up to 450Mbps. This model is designed for connection to the PCI 32/64-bit interface. It supports virtually all the IEEE 802.11 wireless standards, that is 802.11a/b/g including IEEE 802.11n. The card works at 2.4 or 5Ghz, which is perfect for smooth video streaming and on-line gaming and it has a maximum wireless performance of up to 20dBm. It comes with three removable 3 x 2dBi antennas. Naturally, the card supports the Ad-hoc, and infrastructure mode, the dual-band, and many security features, including the WEP, the WPA, and the WPA2 encryption.
