Add 802.11ac Wi-Fi to your Windows desktop system by adding the Archer T6E AC1300 Wireless Dual Band PCI Express Adapter from TP-Link to an available PCIe slot on your system. Combined speeds up to 1300 Mbps are possible, with 867 Mbps on the 5 GHz band and 400 Mbps on the 2.4 GHz band. It is also backwards compatible with 802.11a/b/g/n standards and its two external antennas help ensure a greater range of Wi-Fi connectivity and stability. This Wi-Fi adapter is well-suited for tasks such as HD video streaming, online gaming, and web surfing. WEP, WPA-PSK/WPA2-PSK, and 802.1x 64/128-bit encryption standards help make your connection more secure, while a built-in heat sink helps to dissipate heat generated by this adapter, which in turn helps to increase performance, improve stability, and improve its lifespan.
