ADSL Gateway

Chapter 1: Introduction

Welcome

Thank you for choosing the AG300 ADSL Gateway. This Gateway will provide your computers with a high-speed Internet connection as well as access to local resources, including files and printers.

How does the Gateway do all of this? By connecting the Internet, as well as your computers and peripherals, to the Gateway, you create a LAN, or Local Area Network. The Gateway lets devices on the network communicate with each other, and it can direct and control communications for your network.

To protect your data and privacy, the Gateway features an advanced firewall to keep out Internet intruders. Sensitive communications can be protected by powerful data encryption. In addition, you can safeguard your family with parental control features such as Internet access restrictions and keyword blocking. You can configure the Gateway’s settings 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. 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.

With your PCs and peripherals all connected to each other and to the Internet, you can now share files and Internet access—and even play games. All the while, the ADSL Gateway protects your network from unauthorized and unwelcome users.

Linksys recommends using the Setup CD-ROM for first-time installation of the Gateway. 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 Gateway, set it up, and configure it to bridge your network and the Internet. These instructions should be all you need to get the most out of the ADSL Gateway.

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

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