Wireless AC technology means Archer T4U delivers connections that are up to three times faster than with the previous Wireless N standard. High-speed Wi-Fi (up to 867 Mbps over the 5 GHz band and 400 Mbps over the 2.4 GHz band) means this wireless dual band USB adapter is able to support all your online activities, from HD video streaming to lag-free online gaming and web surfing. With two high gain antennas, Archer T4U greatly extends Wi-Fi range and coverage compared to typical wireless adapters. A stable Wi-Fi network across your home makes for an ideal surfing experience. Thanks to MU-MIMO technology, Archer T4U can provide two simultaneous data streams, improving the throughput and efficiency of the entire network when working with a compatible MU-MIMO router.
