TP-LINK 300MBit/s WLAN-N PCI Express-Adapter Atheros-Chipsatz 2T2R 2,4GHz 802.11b/g/n 2 removeable antennas

Wireless N PCI Express 2.0 adapter TL-WN881ND allows you to connect a desktop computer to a wireless network and access high-speed Internet connection. Comply with IEEE 802.11n, they provide wireless speed up to 300 Mbps, which is beneficial for the online gaming or even HD video streaming.
MIMO (multiple input, multiple output antennas) technology, it shows more excellent abilities of mitigating data loss over long distances and through obstacles in a small office or a large apartment, even in a steel-and-concrete building. Clear Channel Assessment (CCA) automatically avoids channel conflicts using its clear channel selection feature and fully realizes the advantages of channel binding, greatly enhanced the wireless performance.
As for the security of Wi-Fi connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions. TL-WN881ND provides WPA/WPA2 encryptions that are created by the Wi-Fi alliance industry group, promoting interpretabilities and security for WLAN, which could effectively and efficiently protect the wireless network.
