Simultaneous Dual-Band Wireless-N Router
Chapter 1:
Product Overview
Thank you for choosing the Linksys by Cisco Simultaneous
Dual-Band 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.
For more wireless bandwidth, the Router can create two
simultaneous yet separate Wireless-N networks, one
using the 5 GHz band and one using the 2.4 GHz band.
For example, use the Wireless-N 2.4 GHz network to
surf, e-mail, and print while keeping the less crowded,
Wireless-N 5 GHz network free for time-sensitive traffic
like music, gaming, and high-definition video. For more
information, refer to

(Blue) These
numbered
LEDs,
corresponding with the numbered ports on the
Router’s back panel, serve two purposes. If the
LED is continuously lit, the Router is successfully
connected to a device through that port. A
flashing LED indicates network activity over
that port.
Wi-Fi Protected Setup Button
If you have
client devices, such as wireless adapters, that
support Wi-Fi Protected Setup, then you can
use Wi-Fi Protected Setup to automatically
configure wireless security for your wireless
network(s).
To use Wi-Fi Protected Setup, run the Linksys
Easy Link Advisor (LELA) , or refer to
Wi-Fi
Protected Setup
,
page 11

The LED lights up amber if there is an error
during the Wi-Fi Protected Setup process. Make
sure the client device supports Wi-Fi Protected
Setup. Wait until the LED is off, and then try again.
The LED flashes when a Wi-Fi Protected Setup
session is active. The Router supports one
session at a time. Wait until the LED is solidly lit,
or off before starting the next Wi-Fi Protected
Setup session.
Wireless
(Blue) The Wireless LED lights up
when the wireless feature is enabled. If the LED
is flashing, the Router is actively sending or
receiving data over the network.
Internet

when there is a connection made through the
Internet port. A flashing LED indicates network
activity over the Internet port. The LED lights up
Green when it is connected to 10/100 port and
Blue when it is connected to a gigabit port.
Power
(Blue) The Power LED lights up and will
stay on while the Router is powered on. When
the Router goes through its self-diagnostic
mode during every boot-up, this LED will flash.
When the diagnostic is complete, the LED will
