Wireless-G Broadband Router with 2 Phone Ports

Welcome

Thank you for choosing the Linksys Wireless-G Broadband Router with 2 Phone Ports. This Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. Plus, after you have set up your Vonage service, you can make phone or fax calls using your Internet connection.

How does the Router 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 three switched ports or via the wireless broadcast at either up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G. In addition, the WPA standard provides greater security opportunities while the whole network is protected through NAT technology. All of these security features, as well as full configurability, are accessed through the easy-to-use browser-based utility.

But what does all of this mean? Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share

Internet access, so you don’t need more than one high-speed Internet connection. After you set up your Vonage account, you can also use your Internet access to make Internet phone or fax calls, even while you’re surfing the Internet. Plus, 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. All the while, the Router protects your networks from unauthorized and unwelcome users. So, networks not only are useful in homes and offices, but also can be fun.

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”.

Chapter 1: Introduction Welcome

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.

nat (network address translation): NAT technology translated IP addresses of a local area network to a different IP address for the Internet.

mbps: one million bits per second; a unit of measurement for data transmission.

browser: an application program that provides a way to look at and interact with all the information on the World Wide Web.

lan (local area network): the computers and networking products that make up the network in your home or office.

ethernet: an IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.

Wireless-G Broadband Router with 2 Phone Ports

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, which is sometimes called a Wireless Local Area Network (WLAN). The Router bridges wireless networks of both 802.11b and

802.11g standards and wired networks, allowing them to communicate with each other.

802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.

To create your network, install and set up the Router. To guide you through the process, Linksys strongly recommends that you run the Setup Wizard on the Setup CD-ROM. If you prefer to manually set up the Router, use the instructions in the Quick Installation or this Installation and Troubleshooting Guide to help you. These instructions should be all you need to get the most out of the Wireless-G Broadband Router with 2 Phone Ports.

What’s in this Guide?

Chapter 2: Planning Your Wireless Netw ork

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

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 an access point or wireless router, such as the Wireless-G Broadband Router with 2 Phone Ports, 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.

Chapter 2: Planning Your Wireless Network Network Topology

network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users.

ssid: your wireless network’s name.

ad-hoc: a group of wireless devices

communicating directly to each other (peer-to-peer) without the use of an access point.

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

adapter: a device that adds network functionality to your PC.

ethernet: IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.

Wireless-G Broadband Router with 2 Phone Ports

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 with 2 Phone Ports has been specifically designed for use with both your

802.11b and 802.11g products. It is compatible with all 802.11b and 802.11g adapters, such as the Notebook

Network Address Server Settings (DHCP)

These 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. Unless you already have one, it is highly recommended that you leave the Router enabled as a DHCP server.

Local DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, set the Router’s DHCP option to Disable. If you disable DHCP, remember to assign a static IP address to the Router.

Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the default IP address for the Router is 192.168.15.1, the Start IP Address must be 192.168.15. 2 or greater, but smaller than 192.168.15.254. The default Start IP Address is 192.168.15.100.

Number of Address (Optional). 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 50.

DHCP Address Range. The range of DHCP addresses is displayed here. 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 dynamic IP address has expired, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes, which means one day.

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. You can enter 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) converts NetBIOS names to IP addresses. If you use a WINS server, enter that server’s IP address here. Otherwise, leave this field blank.

The Setup Tab - DDNS

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other server behind the Router.

Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers, DynDNS.org or TZO.com. If you do not want to use this feature, keep the default setting, Disable.

ddns: allows the hosting of a website, FTP server, or e-mail server with a fixed domain name (e.g., www.xyz.com) and a dynamic IP address.
