Dual-band Wi-Fi router features an ultra-fast, 1.6 GHZ CPU and provides double the memory capacity of the WRT1900AC to deliver superior wired and Wi-Fi performance. Simultaneous dual band delivers a stronger connection at a wider range than a single band at speeds up to AC1900. Dual-core, central processing unit promotes simultaneous high-speed data processing. 512MB of RAM works in tandem with the 1.6GHz CPU to move movies, music and other large files faster. Four Gigabit Ethernet ports are perfect for transferring large media libraries at speeds 10X 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 eSATA port. Equipped with a four-antenna (detachable) configuration, the router provides exceptional signal strength and range. Advanced wireless security safeguards your network with wireless WPA/WPA2 encryption and an SPI firewall.
