Product Overview

Back Panel

Thank you for choosing the Linksys by Cisco Wireless-G

Home Router with SpeedBurst. 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. A variety

of security features help to protect your data and your

privacy while you are online. Security features include

WPA2 security, a Stateful Packet Inspection (SPI) firewall,

and NAT technology. Configuring the Router is easy using

the provided browser–based utility.

Internet The Internet port is where you will

connect your cable or DSL Internet connection.

4, 3, 2, 1 These Ethernet ports (4, 3, 2, 1)

connect the Router to computers on your wired

network and other Ethernet network devices.

On/Off Push the On/Off button to power on or

off the Router.

Front Panel

Power The Power port connects to the included

power adapter.

Side Panel

1, 2, 3, 4 (Green) 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.

Wireless (Green) The Wireless LED lights up

when the wireless feature is enabled. If the LED

is flashing, the Router is sending or receiving

data over the network.

Reset There are two ways to reset the Router

to its factory defaults. Either press and hold the

Reset button for approximately five seconds, or

restore the defaults from the Administration >

Factory Defaults screen of the Router’s

browser-based utility. (Refer to Administration

> Factory Defaults , page 20 .)

Internet (Green) The Internet LED lights up

when there is a connection made through the

Internet port. It flashes to indicate network

activity over the Internet port.

Horizontal Placement

Power (Green) 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 be solidly lit.

The Router has four rubber feet on its bottom panel. Place

the Router on a level surface near an electrical outlet.
