Wireless-G Broadband Router
Chapter 1: Introduction

Cable/DSL Router
Wireless-G is the upcoming 54Mbps wireless networking standard that’s
almost five times faster than the widely deployed Wireless-B (802.11b) prod-
ucts found in homes, businesses, and public wireless hotspots around the coun-
try—but since they share the same 2.4GHz radio band, Wireless-G devices can
also interoperate with existing 11Mbps Wireless-B equipment.
Since both standards are built in, you can protect your investment in existing
802.11b infrastructure, and migrate to the new screaming fast Wireless-G stan-
dard as your needs grow.
The Linksys Wireless-G Broadband Router is really three devices in one box.
First, there’s the Wireless Access Point, which lets you connect Wireless-G or
Wireless-B devices to the network.
There’s also a built-in 4-port full-duplex
10/100 Switch to connect your wired-Ethernet devices. Connect four PCs
directly, or daisy-chain out to more hubs and switches to create as big a network
as you need.
Finally, the Router function ties it all together and lets your whole
network share a high-speed cable or DSL Internet connection.
To protect your data and privacy, the Wireless-G Broadband Router can encrypt
all wireless transmissions.
The Router can serve as a DHCP Server, has NAT
technology to protect against Internet intruders, supports VPN pass-through,
and can be configured to filter internal users’ access to the Internet.
Configuration is a snap with the web browser-based configuration utility.
With the Linksys Wireless-G Broadband Router at the center of your home or
office network, you can share a high-speed Internet connection, files, printers,
and multi-player games with the flexibility, speed, and security you need!

What’s an IP Address?
IP stands for Internet Protocol. Every device on 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 an IP address to your network devices. You can
assign static IP addresses or use the Router to assign IP addresses dynamically.
Static IP Addresses
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 must be
unique and 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 that information from your ISP.
IP Addresses
Note:
Since the Router is a device that connects two networks, it
needs two IP addresses—one for the LAN, and one for the Internet.
In
this User Guide, you’ll see references to the “Internet IP address” and
the “LAN IP address.”
Since the Router uses NAT technology, the only IP address that can be
seen from the Internet for your network is the Router’s Internet IP
address.
However, even this Internet IP address can be blocked, so that the
Router and network seem invisible to the Internet—see the Block
WAN Requests description under Filters in “Chapter 6: The Router’s
Web-based Utility.”

Simply put, a router is a network device that connects two networks together.
In this instance, 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 NAT feature protects your network of PCs so users on the public,
Internet side cannot “see” your PCs.
This is how your network remains private.
The Router protects your network by inspecting every packet coming in
through the Internet port before delivery to the appropriate PC on your net-
work. 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.
Remember that the Router’s ports connect to two sides. The LAN ports connect
to the LAN, and the Internet port connects to the Internet.
The LAN and
Internet ports transmit data at 10/100Mbps.
