TP-LINK's Archer T4E supports the advanced Wi-Fi standard of IEEE 802.11ac, offering 3 times transferring rates as IEEE 802.11n. You can send emails and browse the web with 2.4GHz network, while keeping the speedy 5GHz band free for gaming, HD streaming and other bandwidth intensive applications.Greater Coverage with Beamforming
Beamforming technology smartly focuses Wi-Fi signals towards connected devices for stable connections and boosted range.Heat Sink for Ultimate Stability
A heat sink helps to dissipate the thermal energy generated by the adapter, which in turn improves stability. Additionally, lower temperatures help to extend the product lifespan.External Antennas for More Targeted signal
Two external antennas utilize the latest wireless technology to achieve stable connections and boosted coverage.*Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput and wireless coverage are not guaranteed and will vary as a result of 1) environmental factors, including building materials, physical objects, and obstacles, 2) network conditions, including local interference, volume and density of traffic, product location, network complexity, and network overhead, and 3) AP limitations, including rated performance, location, connection quality, and AP condition.*To ensure compatibility, you may need to update the adapter’s drivers after an OS update.
