Wireless-N ADSL2+ Gateway
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-N ADSL2+ Gateway. The Gateway will allow you to network wirelessly better
than ever, sharing Internet access, files and fun, easily and securely and with a greater range of up to three times
farther than standard Wireless-G.
The incredible speed of Wireless-N makes it ideal for media-centric applications like streaming video and Voice
over IP (VoIP) telephony, so your network can handle multiple data streams at the same time, with no degradation
in performance.
How does the Gateway do all of this? By connecting the Internet, as well as your computers and peripherals, to
the Gateway, then the Gateway can direct and control communications for your network. Plus, since the Gateway
is wireless, Internet access can be shared over the wireless broadcast as well as the wired network.
Use wireless security to secure your wireless network while the whole network is protected through a Stateful
Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. The Gateway also offers VPN
passthrough and other features, which can be configured 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.
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. Since the Gateway has
wireless capabilities, it can bridge your wired and wireless networks, letting them communicate with each other.
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 different networks. These instructions should be all you need to get the
most out of the Wireless-N ADSL2+ Gateway.
