Advanced Wireless-N Router
Chapter 1: Product Overview
Thank you for choosing the Linksys E2100L Advanced
Wireless-N Router. The Router lets you access the Internet
via a wireless connection or through one of its four
switched ports. You can also use the Router to share
resources such as computers, printers and files. The
Router’s USB port connects to a USB storage device, so
you can access your portable files. (A USB hard drive may
require an external power supply.)
A variety of security features help to 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; a Stateful Packet
Inspection (SPI) firewall to help block unauthorized access
to your Router; and Network Address Translation (NAT)
technology, which enhances network protection by
allowing your computers to share Internet access through
a single, public Internet (IP) address. (IP stands for Internet
Protocol.)
Setup and use of the Router is easy using Cisco Connect,
the software that is installed when you run the included
CD. Advanced configuration of the Router is available
through the provided browser-based utility.

Wi-Fi Protected Setup Button If you have
client devices, such as wireless adapters,
that support Wi-Fi Protected Setup, then you
