Linksys Simultaneous Dual-Band Wireless-N Router, Model WRT400N

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 set up; includes Mac setup wizard.

Key Features:

  • Expanded wireless coverage—far more range than 802.11g products
  • Complies with the draft IEEE 802.11n standard
  • Blazing fast wireless speeds for high bandwidth applications such as video streaming or file sharing
  • All ports support auto-crossover (MDI/MDI-X)—no need for crossover cables
  • MIMO technology uses multiple radios to create a robust signal that travels farther and faster, with reduced dead spots
  • Performance investment protection: Compatibility with Wireless-A (802.11a), Wireless-B (802.11b), and Wireless-G (802.11g) standards
  • Supports up to 128-bit encryption security


  • 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
