Wireless-G Broadband Router with 2 Phone Ports

Chapter 1: Introduction

Welcome

Thank you for choosing the Linksys Wireless-G Broadband Router with 2 Phone Ports. The Wireless-G Broadband
Router with 2 Phone Ports will allow you to network wirelessly better than ever, sharing Internet access, files and
fun, easily and securely.

How does the Wireless-G Broadband Router with 2 Phone Ports do all of this? A router is a device that allows
access to an Internet connection over a network. With the Wireless-G Broadband Router with 2 Phone Ports, this
access can be shared over the four switched ports or via the wireless broadcast at up to 11Mbps for Wireless-B
or up to 54Mbps for Wireless-G.

Use the WPA standard to secure your wireless network while the whole network is protected through a Stateful
Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. Just run the Setup Wizard and
it will guide you through the steps to set up your network. You can also access the Router’s features through the
easy-to-use, browser-based utility.

But what does all of this mean?

Networks are useful tools for sharing computer resources. You can access one printer from different computers
and access data located on another computer's hard drive. Networks are even used for playing multiplayer video
games. So, networks are not only useful in homes and offices, they can also be fun.

NOTE: The Setup Wizard is not compatible with
Mac

® computers. Refer to Chapter 4: Connecting the

Wireless-G Broadband Router with 2 Phone Ports and
Chapter 5: Configuring the Wireless-G Broadband
Router with 2 Phone Ports.

wpa (wi-fi protected access): a wireless security
protocol using TKIP (Temporal Key Integrity Protocol)
encryption, which can be used in conjunction with a
RADIUS server.

spi (stateful packet inspection) firewall: a technology
that inspects incoming packets of information before
allowing them to enter the network.

firewall: Security measures that protect the
resources of a local network from intruders.

PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called “wired”.

PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called
a WLAN, or Wireless Local Area Network. The Wireless-G Broadband Router with 2 Phone Ports bridges wireless
networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each
other.

With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet
access—and even play games. All the while, the Wireless-G Broadband Router with 2 Phone Ports protects your
networks from unauthorized and unwelcome users.

Linksys recommends using the Setup CD-ROM for first-time installation of the Router. If you do not wish to run
the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the

Chapter 2: Planning Your Wireless Network

Network Topology

A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each
computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same
frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the
same wireless network.

Ad-Hoc versus Infrastructure Mode

ssid (service set identifier): your wireless network’s name.

Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure
and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other.
Choosing between these two modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.

If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral,
such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure
mode. The basis of Infrastructure mode centers around a wireless router or an access point, such as the
Wireless-G Broadband Router, which serves as the main point of communications in a wireless network. The
Router transmits data to PCs equipped with wireless network adapters, which can roam within a certain radial
range of the Router. You can arrange the Router and multiple access points to work in succession to extend the
roaming range, and you can set up your wireless network to communicate with your Ethernet hardware as well.

If the wireless network is relatively small and needs to share resources only with the other computers on the
wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless
transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or
access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to
communicate with computers on a wired network. And, of course, communication between the wireless­equipped computers is limited by the distance and interference directly between them.

Network Layout

The Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g
products. Now, products using these standards can communicate with each other.

infrastructure: a wireless network that is bridged
to a wired network via an access point.

ad-hoc: a group of wireless devices
communicating directly to each other (peer-to­peer) without the use of an access point.

Chapter 2: Planning Your Wireless Network

Placement Options

There are three ways to place the Router. The first way is to place it horizontally on a surface, so it sits on its four rubber feet.
Another option is to install the stand onto the bottom of the Router, so the Router is in an upright position. Make sure to place
the Router’s bottom edge of the Cisco logo in between the stand’s prongs until tight. The third way is to mount it on a wall.This
option uses the Router’s four wall-mount slots on its bottom panel. The distance between two adjacent slots is 60 mm (2.36
inches).

To use the wall-mount option, follow these instructions:

1. Make sure you have four screws that are size #4—this indicates a diameter measurement of 2.845 mm (0.112 inches).

2. Determine where you want to mount the Router.

3. Drill four holes into the wall. Make sure adjacent holes are 60 mm (2.36 inches) apart.

4. Insert a screw into each hole, and leave 5 mm (0.2 inches) of its head exposed.

5. Maneuver the Router so the wall-mount slots line up with the four screws.

6. Place the wall-mount slots over the screws and slide the Router down until the screws fit snugly into the wall-mount
slots.

Optional Settings

Some of these settings may be required by your ISP. Verify with your ISP before making any changes.

Router Name. In this field, you can type a name of up to 39 characters to represent the Router.

Host Name/Domain Name. These fields allow you to supply a host and domain name for the Router. Some ISPs,

usually cable ISPs, require these names as identification. You may have to check with your ISP to see if your
broadband Internet service has been configured with a host and domain name. In most cases, leaving these
fields blank will work.

MTU. MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet
transmission. The default setting, Manual, allows you to enter the largest packet size that will be transmitted.
The recommended size, entered in the Size field, is 1492. You should leave this value in the 1200 to 1500 range.

Router IP

This presents both the Router’s IP Address and Subnet Mask as seen by your network.

Network Address Server Settings (DHCP)

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The
Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to
each computer on your network. If you choose to enable the Router’s DHCP server option, you must configure all
of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on
your network.

DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you
don’t want a DHCP server, then click the Disable radio button (no other DHCP features will be available).

Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
Router’s default IP address is 192.168.0.1, the Starting IP Address must be 192.168.0.2 or greater, but smaller
than 192.168.0.253. The default Starting IP Address is 192.168.0.100.

Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign
IP addresses to. This number cannot be greater than 253. The default is 64.

Figure 5-9: Router IP

Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”
this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address.
The default is 0 minutes, which means one day.

Static DNS (1-3). The Domain Name System (DNS) is how the Internet translates domain or website names into
Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. If you wish to use
another, type that IP Address in one of these fields. You can type up to three DNS Server IP Addresses here. The
Router will use these for quicker access to functioning DNS servers.

WINS. The Windows Internet Naming Service (WINS) manages each PC’s interaction with the Internet. If you use
a WINS server, enter that server’s IP Address here. Otherwise, leave this blank.

Time Setting

Change the time zone in which your network functions from this pull-down menu. (You can even automatically
adjust for daylight savings time.)

The Wireless Tab - Wireless Security

The Wireless Security settings configure the security of your wireless network. There are four wireless security
mode options supported by the Router: WPA Personal, WPA Enterprise, WPA2 Personal, WPA2 Enterprise, RADIUS,
and WEP. (WEP stands for Wired Equivalent Privacy, WPA stands for Wi-Fi Protected Access, which is a security
standard stronger than WEP encryption. WPA2 is stronger than WPA. WPA Enterprise is WPA used in coordination
with a RADIUS server. RADIUS stands for Remote Authentication Dial-In User Service.) These are briefly discussed
here. For detailed instructions on configuring wireless security for the Router, turn to “Appendix B: Wireless
Security.”

WPA Personal. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the
type of algorithm, TKIP or AES. Enter a WPA Shared Key of 8-63 characters. Then enter a Group Key Renewal
period, which instructs the Router how often it should change the encryption keys.

WPA Enterprise. This option features WPA used in coordination with a RADIUS server. (This should only be used
when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use, TKIP
or AES. Enter the RADIUS server’s IP Address and port number, along with a key shared between the Router and
the server. Last, enter a Key Renewal Timeout, which instructs the Router how often it should change the
encryption keys.

IMPORTANT: If you are using WPA, always
remember that each device in your wireless
network MUST use the same WPA method
and shared key, or else the network will not
function properly.
