Product Overview

Chapter 1: Product Overview

Thank you for choosing the Linksys Dual-band Wireless-N Gigabit 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. A variety of security features help to protect your data and your privacy while 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.

Front Panel

1, 2, 3, 4 (Green/Blue) These numbered LEDs,

corresponding with the numbered ports on the Router’s back panel, serve two purposes. The LED is solidly lit when the Router is connected to a device through that port. It flashes to indicates network activity. Green indicates Gigabit speeds, and blue indicates 10/100 speeds.

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 Setup Wizard, or refer to the “Wireless > Basic Wireless Settings” section of “Chapter 3: Advanced Configuration”.

Wi-Fi Protected Setup LED (Blue/Amber) It

lights up blue when wireless security is enabled. The LED flashes blue for two minutes during Wi-Fi Protected Setup.

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 amber when a Wi-Fi Protected Setup session is active, and a second session begins. The Router supports one session at a time. Wait until the LED is 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.

Wireless Security Checklist

Chapter 2: Wireless Security Checklist

Wireless networks are convenient and easy to install, so homes with high-speed Internet access are adopting them at a rapid pace. Because wireless networking operates by sending information over radio waves, it can be more vulnerable to intruders than a traditional wired network. Like signals from your cellular or cordless phones, signals from your wireless network can also be intercepted. Since you cannot physically prevent someone from connecting to your wireless network, you need to take some additional steps to keep your network secure.

1. Change the default wireless network name or SSID

Wireless devices have a default wireless network name or Service Set Identifier (SSID) set by the factory. This is the name of your wireless network, and can be up to 32 characters in length. Linksys wireless products use linksys as the default wireless network name. You should change the wireless network name to something unique to distinguish your wireless network from other wireless networks that may exist around you, but do not use personal information (such as your Social Security number) because this information may be available for anyone to see when browsing for wireless networks.

2. Change the default password

For wireless products such as access points and routers, you will be asked for a password when you want to change their settings. These devices have a default password set by the factory. The Linksys default password is admin. Hackers know these defaults and may try to use them to access your wireless device and change your network settings. To thwart any unauthorized changes, customize the device’s password so it will be hard to guess.

4. Enable encryption

Encryption protects data transmitted over a wireless network. Wi-Fi Protected Access (WPA/WPA2) and Wired Equivalent Privacy (WEP) offer different levels of security for wireless communication.

A network encrypted with WPA/WPA2 is more secure than a network encrypted with WEP, because WPA/WPA2 uses dynamic key encryption. To protect the information as it passes over the airwaves, you should enable the highest level of encryption supported by your network equipment.

WEP is an older encryption standard and may be the only option available on some older devices that do not support WPA.

General Network Security Guidelines

Wireless network security is useless if the underlying network is not secure.

• Password protect all computers on the network and

individually password protect sensitive files.

• Change passwords on a regular basis.

• Install anti-virus software and personal firewall

software.

• Disable file sharing (peer-to-peer). Some applications

may open file sharing without your consent and/or knowledge.

Additional Security Tips

• Keep wireless routers, access points, or gateways away

from exterior walls and windows.

• Turn wireless routers, access points, or gateways

off when they are not being used (at night, during vacations).

• Use strong passphrases that are at least eight characters

in length. Combine letters and numbers to avoid using standard words that can be found in the dictionary.

3. Enable MAC address filtering

Linksys routers give you the ability to enable Media Access Control (MAC) address filtering. The MAC address is a unique series of numbers and letters assigned to every networking device. With MAC address filtering enabled, wireless network access is provided solely for wireless devices with specific MAC addresses. For example, you can specify the MAC address of each computer in your home so that only those computers can access your wireless network.

A MAC address is a 12-digit code assigned to a unique piece of hardware for identification. Some ISPs will require you to register a MAC address in order to access the Internet. If you do not wish to re-register the MAC address with your ISP, you may assign the MAC address you have currently registered with your ISP to the Router with the MAC Address Clone feature.

NAT

Enabled/Disabled If this Router is hosting your network’s

connection to the Internet, keep the default, Enabled. If another router exists on your network, select Disabled. When the NAT setting is disabled, dynamic routing will be enabled.

Dynamic Routing (RIP)

Enabled/Disabled This feature enables the Router to

automatically adjust to physical changes in the network’s layout and exchange routing tables with the other router(s). The Router determines the network packets’ route based on the fewest number of hops between the source and the destination. When the NAT setting is enabled, the Dynamic Routing feature is automatically disabled. When the NAT setting is disabled, this feature is available. Select Enabled to use the Dynamic Routing feature.

and another network, select a number from the dropdown list. Click Delete This Entry to delete a static route.

Enter Route Name Enter a name for the Route here,

using a maximum of 25 alphanumeric characters.

Destination LAN IP The Destination LAN IP is the address

of the remote network or host to which you want to assign a static route.

Subnet Mask The Subnet Mask determines which

portion of a Destination LAN IP address is the network portion, and which portion is the host portion.

Gateway This is the IP address of the gateway device that

allows for contact between the Router and the remote network or host.

Interface This interface tells you whether the Destination

IP Address is on the LAN & Wireless (Ethernet and wireless networks) or the WAN (Internet).

Wireless > Basic Wireless Settings

The basic settings for wireless networking are set on this screen.

There are two ways to configure the Router’s wireless network(s), manual and Wi-Fi Protected Setup.

Wi-Fi Protected Setup is a feature that makes it easy to set up your wireless network. If you have client devices, such as wireless adapters, that support Wi-Fi Protected Setup, then you can use Wi-Fi Protected Setup.

Configuration View To manually configure your wireless

network, select Manual. Proceed to the “Basic Wireless Settings” section. To use Wi-Fi Protected Setup, select

Wi-Fi Protected Setup. Proceed to the “Wi-Fi Protected Setup” section.

Basic Wireless Settings

Wireless > Basic Wireless Settings (Manual Setup)

Wireless Band This is used to select the 2.4 GHz or

5.0 GHz band.

Network Mode From this drop-down menu, you can

select the wireless standards running on your network. If you have Wireless-N, Wireless-G, and Wireless-B devices in your network, keep the default setting, Mixed. If you have only Wireless-G and Wireless-B devices in your network, select BG-Mixed. If you have only Wireless-N devices, select Wireless-N Only. If you have only Wireless-G devices, select Wireless-G Only. If you have only Wireless-B devices, select Wireless-B Only. If you do not have any wireless devices in your network, select Disabled.

Network Name (SSID) The SSID is the network name

shared among all points in a wireless network. The SSID must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 characters (use any of the characters on the keyboard). Make sure this setting is the same for all points in your wireless network. For added security, you should change the default SSID (linksys) to a unique name.

Channel Width Select Auto if you want the Router

to automatically determine the proper channel width (20 MHz or 40 MHz) to use, or select 20 MHz only (default) if you want the Router to operate in Wireless-B and Wireless-G mode only. For best performance, Auto is recommended.

Wide Channel If you selected Wide - 40MHz Channel for

the Radio Band setting, then this setting will be available for your primary Wireless-N channel. Select any channel from the drop-down menu. If you are not sure which channel to select, keep the default, Auto.

Channel Select a channel from 1 to 11, or Auto (default).

SSID Broadcast When wireless clients survey the local

area for wireless networks to associate with, they will detect the SSID broadcast by the Router. To broadcast the

Wi-Fi Protected Setup

There are three methods available. Use the method that applies to the client device you are configuring.

Wireless > Basic Wireless Settings (Wi-Fi Protected Setup)

NOTE: Wi-Fi Protected Setup configures one

client device at a time. Repeat the instructions for each client device that supports Wi-Fi Protected Setup.

Method #1

Use this method if your client device has a Wi-Fi Protected Setup button.

1. Click or press the Wi-Fi Protected Setup button on

the client device.

2. Click the Wi-Fi Protected Setup button on this

screen.

3. After the client device has been configured, click

OK. Then refer back to your client device or its documentation for further instructions.

Method #2

Method #3

Use this method if your client device asks for the Router’s PIN number.

1. Enter the PIN number listed on this screen. (It is also listed on the label on the bottom of the Router.)

2. After the client device has been configured, click OK. Then refer back to your client device or its documentation for further instructions.

The Wi-Fi Protected Setup Status, Network Name (SSID), Security, Encryption, and Passphrase are displayed at the bottom of the screen.

NOTE: If you have client devices that do not

support Wi-Fi Protected Setup, note the wireless settings, and then manually configure those client devices.

Wireless > Wireless Security

The Wireless Security screen configures the security of your wireless network. There are six wireless security mode options supported by the Router: WPA Personal, WPA Enterprise, WPA2 Personal, WPA2 Enterprise, RADIUS, and WEP. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These six are briefly discussed here. For detailed instructions on configuring wireless security for the Router, refer to “Chapter 2: Wireless Security.”
