Linksys WRT400N Datasheet

Simultaneous Dual-Band
Wireless-N Router
Model: WRT400N
Double-N performance
Built for speed, the Simultaneous Dual-Band Wireless-N Router delivers double the
bandwidth so you can enjoy movies, gaming and music more smoothly, with less lag, all
around your home. Easy to use and setup; includes Mac setup wizard.
Double Bandwidth
Experience faster wireless connectivity with fewer interruptions with two bands of
Wireless-N, today’s most advanced wireless technology. The 5 GHz and 2.4 GHz bands are
designed to work separately yet simultaneously, so you can easily customize your ideal
configuration—for example, use the 2.4 GHz band to surf, email and print while keeping
the less crowded 5 GHz band free for time sensitive traffic like music, gaming and high-
definition video.
Reliable Coverage
Experience coverage you can count on, all around your home. Wireless-N’s Multiple in,
Multiple Out MIMO technology actually uses the signal reflections that confuse ordinary
wireless technologies to boost range and reduce dead spots.
Connect to More
Four 10/100 Ethernet ports let you connect printers, networked storage drives, and other
Ethernet-enabled devices to your network, so you can access and share them wirelessly
from all your computers at once. No need to trade cables, or wait for someone else to
finish their work before you do yours.
Advanced Security
Advanced wireless security and SPI firewall protection is designed to help safeguard your
home network and computers from most Internet attacks. Includes 30 day free trial of
Home Network Defender, designed to protect you and your family against cybercriminals
and online predators by stopping threats before they get into your home network.
