Broadband Router with 2 Phone Ports

Chapter 1: Introduction

Welcome

Thank you for choosing the Broadband Router with 2 Phone Ports. This Router will allow your computers to share a high-speed Internet connection as well as resources, including files and printers. And after you have set up your Internet phone service, you will be able to make phone or fax calls using the Internet.

How does the Router do all of this? By connecting your computers and peripherals, including phones or fax machines, to the Router and connecting the Router to your cable or DSL modem, then the Router can direct and control communications for your network.

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. With Internet phone service, your Internet access can now be shared by your phones or fax machines as well. Y ou will be able to make phone calls using the account you set up with your Internet phone service provider, 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. 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”.

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 User Guide to help you. These instructions should be all you need to get the most out of the Router.

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

Chapter 2: Networking Basics

An Introduction to Local Area Networks

Simply put, a router is a network device that connects two networks together. The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet. The

Router processes and regulates the data that travels between these two networks. The Router’s Network Address Translation (NA T) technology protects your network of PCs so users on the Internet

cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by inspecting the first packet coming in through the Internet port before delivery to the final destination on one of the Ethernet ports. The Router inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.

The Use of IP Addresses

IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its location, or address, on the network. This applies to both the Internet and LAN connections.

There are two ways of assigning IP addresses to your network devices. A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a

static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses are commonly used with network devices such as server PCs or print servers.

If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Router. You can get the information from your ISP.

A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.

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

static ip address: a fixed address assigned to a computer or device that is connected to a network.

dynamic ip address: a temporary IP address assigned by a DHCP server.

dhcp (dynamic host configuration protocol): a protocol that lets one device on a local network, known as a DHCP server, assign temporary IP addresses to the other network devices, typically computers.

Chapter 2: Networking Basics An Introduction to Local Area Networks

Broadband Router with 2 Phone Ports

A DHCP server can either be a designated PC on the network or another network device, such as the Router. By default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP).

The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.

For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet. This is a dedicated, high-speed connection type called Point to Point Protocol over Ethernet (PPPoE). PPPoE is similar to a dial-up connection, but PPPoE does not dial a phone number when establishing a connection. It also will provide the Router with a dynamic IP address to establish a connection to the Internet.

By default, a DHCP server (on the LAN side) is enabled on the Router. If you already have a DHCP server running on your network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Router, see the Basic Setup section in “Chapter 5: Configuring the Router.”
