Getting to know the Linksys Smart Wi-Fi Router, E4200

What is the Linksys Smart Wi-Fi Router, E4200?

The Linksys Smart Wi-Fi Router, E4200 lets you access the Internet through wired and wireless connection.  With the built-in Storage Link, you can easily add Gigabytes of storage space onto your network using USB 2.0 hard drives, or plug in a USB flash disk to access your portable data files.  The Linksys Smart Wi-Fi Router, E4200's built-in media server streams music, video and photos from an attached storage device to any UPnP-compatible media adapter or player.

Various security features help protect your data and your privacy while you are online.  Security features include:

      •    Wi-Fi Protected Access 2 (WPA2) security, which encrypts data on your wireless network; 
      •    Stateful Packet Inspection (SPI) firewall to help block unauthorized access to your router;
      •    Network Address Translation (NAT) technology, which enhances network protection by allowing your computers to share Internet access through a single, public Internet IP address.

Setup and use of the router is easy using Linksys Connect, the software that is installed when you run the included CD.  Advanced configuration of the router is available through the provided web-based setup page.

For more wireless bandwidth, the router can create two (2) simultaneous yet separate Wireless-N networks, one using the 5 GHz radio frequency band and one using the 2.4 GHz band.  For example, you may use the Wireless-N 2.4 GHz network to surf, email, and print while keeping the less crowded, Wireless-N 5 GHz network free for time-sensitive traffic like Voice over IP (VoIP) calls, online gaming, and high-definition video.  The Guest Access feature allows you to provide Internet access to guests visiting your home without granting them access to your local network.
