PERFORMANCE PERFECTED Years in the making, the WRT1900AC is the best router in its class. At speeds of 1.9 Gbps, it delivers unmatched performance for the most demanding networks. Equipped with the industry's first four-antenna configuration and professional-grade 1.2 GHz dual-core CPU, the WRT1900AC provides exceptional signal strength and range. USB 3.0, ESATA, & GIGABIT ETHERNET PORTSTO SHARE FILES The WRT1900AC's four Gigabit Ethernet ports are perfect for transferring large media libraries at speeds 10 times faster than Fast Ethernet. To stream or send large files across your network at high speed, simply connect a flash drive to the USB 3.0 port or an external SATA storage device to the unique eSATA port. For printing or working with smaller files, the eSATA port also serves as a USB 2.0 port. FOUR EXTERNAL ANTENNAS FOR GREATER RANGE & COVERAGE The WRT1900AC features four external adjustable high-performance antennas that provide strong, reliable coverage throughout your home. This unique antenna diversity technology helps your laptop, tablet, smartphone, and other connected devices achieve optimal performance, wherever they are in the home. The antennas also enhance coverage for both 2.4Ghz and 5Ghz bands, keeping everyone simultaneously gaming, downloading, and streaming without lag. BEAMFORMING FOR STRONGER, MORE FOCUSED WI-FI CONNECTIONS Designed especially for today's mobile-device household, the WRT1900AC features beamforming technology, which focuses wireless signals at a receiving device rather than simply sending out Wi-Fi in a general direction. Beamforming also reduces interference from other devices for stronger Wi-Fi connections. It increases the efficiency of your network and expands its range, enabling you to enjoy high-bandwidth activities like streaming and gaming with ease. FAST 1.2 GHZ DUAL-CORE PROCESSOR TO SURF, STREAM, & GAME SIMULTANEOUSLY With a professional-grade, 1.2 GHz dual-core ARM processor, the WRT1900AC is one of the fastest Wireless-AC routers in its class. Unlike standard single-core processors which have to switch between data streams and aren't as suited for multitasking, a dual-core processor can handle multiple data streams simultaneously. The result: better efficiency and performance, particularly in today's multi-device world. LINKSYS SMART WI-FI Linksys Smart Wi-Fi lets you access your network anytime, anywhere.
