The ASUS RT-AC66U router integrates dual-band Gigabit wireless with fifth generation 802.11ac Wi-Fi technology, also known as 5G WiFi, which enables speeds up to three times faster than existing 802.11n. As one of the first routers to achieve this, it tops Gigabit wireless requirements with a combined 2.4 GHz/5 GHz bandwidth of 1.75 Gbps. This massive data rate makes it an excellent high speed router for demanding online applications, coupled with exclusive ASUS AiRadar signal amplification and shaping technology. Easy ASUSWRT setup, multiple SSIDs, and IPv6 support further enhance networking, while strong USB-based capabilities turn the RT-AC66U into a 3G, FTP, DLNA, and printer server for genuine multi-role functionality. Going beyond Gigabit Wi-Fi to triple wireless-N speeds The RT-AC66U goes even further than the successful high speed RT-N66U dual-band router. Working in both 2.4 GHz and 5 GHz, it is one of the world's first dual-band wireless routers to support the advanced 802.11ac wireless protocol, enabling 5 GHz operation at up to 1.3 Gbps. These new capabilities are made possible by the inclusion of Broadcom's powerful 5G WiFi chips. As the 2.4 GHz band can work at 450 Mbps on its own, the concurrent combined bandwidth of the RT-AC66U is 1.75 Gbps. It uses sophisticated ASUS AiRadar technology to strengthen signals to devices, amplifying transmission in all directions to better overcome environmental obstructions and improve data rates. The inclusion of 5G WiFi makes the RT-AC66U one of the most future-proof routers on the market, ready for the next generation of high speed networks. Extensive feature list enhances networking experiences The RT-AC66U maintains the tradition of networking excellence established by previous ASUS high speed routers. It allows for easy and fast setup in just three steps with the ASUSWRT dashboard, and upholds strict QoS standards for the most reliable networking and download multitasking available. With QoS, the RT-AC66U has better bandwidth optimization, and offers Download Master capabilities, which mean fast background downloading even post-shutdown. Up to eight SSIDs are supported, so users can easily setup distinct networks with different access privileges and levels of security without having to compromise passwords. The RT-AC66U supports the new IPv6 standard for better packet transmission and addressing. USB applications extend router versatility With its twin USB ports, the RT-AC66U becomes a true multi-role device. Attaching a 3G dongle allows it to share 3G connections among several users on different devices, while full DLNA compatibility affords smooth connectivity with a variety of entertainment platforms, including game consoles, Blu-ray players, smart TVs, and set-top boxes. The RT-AC66U can also serve as a dedicated FTP server and printer server, letting users share resources for greater productivity while reducing costs as there is no need to buy standalone server hardware. Full 802.11ac product lineup In addition to the RT-AC66U router, ASUS has also released the PCE-AC66 and USB-AC53 clients, both capable of 802.11ac speeds. The dual-band PCE-AC66 offers a PCI Express client card for desktops, with 3 x 3 high-powered transmission. It can sustain 1.3 Gbps in 5 GHz and up to 450 Mbps in the 2.4 GHz band. For easy USB upgrades to 802.11ac, the USB-AC53 compact dongle plugs into any USB port, with 2 x 2 802.11ac. In 5 GHz, the attachment can maintain 867 Mbps, while in 2.4 GHz it works at 300 Mbps, achieving a total throughput of around 1.3 Gbps. The PCE-AC66 and USB-AC53 are enabled by Broadcom's 5G WiFi chips, and demonstrate ASUS technology leadership in bringing an 802.11ac ecosystem to consumers.
