PERFORMANCE PERFECTED™

With an advanced 1.6 GHz dual-core CPU and an impressive 512MB of RAM, the WRT1900ACS delivers improvements in wired, wireless, and network storage performance over its predecessor, the WRT1900AC. At speeds up to N600 + AC1300 Mbps, the WRT1900ACS meets the needs of the most demanding home Wi-Fi networks. Equipped with a four-antenna configuration, the router provides exceptional signal strength and range. Advanced users also have the option of modifying the router with open source firmware.

1.6 GHz Processor

ADVANCED 1.6 GHZ DUAL-CORE PROCESSOR TO SURF, STREAM, & GAME SIMULTANEOUSLY

With a professional-grade 1.6 GHz dual-core ARM processor, the WRT1900ACS delivers faster throughput speeds and easily handles multiple data streams simultaneously. The result: better performance, particularly in today's multi-device homes.

512MB OF RAM FOR IMPROVED DATA TRANSFER

The WRT1900ACS comes equipped with 512MB of RAM that works in tandem with the 1.6GHz CPU to move movies, music, and other large files faster. With more than double the memory of its predecessor, the WRT1900ACS improves data transfer speeds, allowing you to do more, faster.


USB 3.0, ESATA, and Gigabit Ethernet

USB 3.0, ESATA, & GIGABIT ETHERNET PORTS TO SHARE FILES

The WRT1900ACS has four Gigabit Ethernet ports that 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. The eSATA port also serves as a USB 2.0 port.


Linksys WRT1900ACS Ports

FOUR EXTERNAL ANTENNAS FOR GREATER RANGE & COVERAGE

The WRT1900ACS features four external, adjustable high-performance antennas that provide strong, reliable coverage throughout your home. The unique antenna diversity technology onboard helps your laptop, tablet, smartphone, and other connected devices achieve an optimal connection, wherever they are in your home. The antennas also enhance coverage for both 2.4GHz and 5GHz bands, keeping everyone gaming, downloading, and streaming without lag.

BEAMFORMING FOR STRONGER, MORE FOCUSED WI-FI CONNECTIONS

Designed especially for today's mobile-device households, the WRT1900ACS features Beamforming technology, which focuses wireless signals at a receiving device rather than simply sending out Wi-Fi in a general direction.


Open Source Ready

OPEN SOURCE READY

While the Linksys WRT1900ACS provides an outstanding experience via Smart Wi-Fi immediately out of the box, advanced users can further modify the router with open source firmware. Developed for use with OpenWRT, an open source, Linux-based operating system, the router offers an additional layer of customization to suit your needs.

*The standard transmission rates—450 Mbps or 1300 Mbps (for 5 GHz), 600 Mbps (for 2.4 GHz), 54 Mbps, and 11 Mbps—are the physical data rates. Actual data throughput will be lower and may depend on the mix of wireless products used and external factors.
**While Linksys fully embraces the open source community and is providing open source use capabilities, they do not offer technical support on using open source firmware. Installing 3rd party firmware is done at your own risk and replacing factory-installed firmware with open source firmware will void your warranty. Please always seek the advice of more experienced users via open source community forums if you’re unsure.
