Introduction
This chapter describes the features of the NETGEAR MR814 v3 Cable/DSL Wireless Router.
Key Features of the Router
The MR814 v3 Cable/DSL Wireless Router with 4-port switch connects your local area network
(LAN) to the Internet through an external access device such as a cable modem or DSL modem.
The MR814 v3 router provides you with multiple Web content filtering options, plus browsing
activity reporting and instant alerts -- both via e-mail. Parents and network administrators can
establish restricted access policies based on time-of-day, Web site addresses and address
keywords, and share high-speed cable/DSL Internet access for up to 253 personal computers. In
addition to the Network Address Translation (NAT) feature, the built-in firewall protects you from
hackers.
With minimum setup, you can install and use the router within minutes.
The MR814 v3 router provides the following features:
802.11b Standards-based wireless networking
WPA-PSK wireless security.
Easy, web-based Smart Wizard configuration assistant
Content Filtering and Site Blocking Security
Built in 4-port 10/100 Mbps Switch
Ethernet connection to a wide area network (WAN) device, such as a cable modem or DSL
modem
Extensive Protocol Support
Login capability
Front panel LEDs for easy monitoring of status and activity
Flash memory for firmware upgrade
Reference Manual for the MR814 v3 Cable/DSL Wireless Router
Introduction 2-3
202-10039-01
Security
The MR814 v3 router is equipped with several features designed to maintain security, as described
in this section.
PCs Hidden by NAT
NAT opens a temporary path to the Internet for requests originating from the local network.
Requests originating from outside the LAN are discarded, preventing users outside the LAN
from finding and directly accessing the PCs on the LAN.
Port Forwarding with NAT
Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the
router allows you to direct incoming traffic to specific PCs based on the service port number
of the incoming request, or to one designated “DMZ” host computer. You can specify
forwarding of single ports or ranges of ports.
Autosensing Ethernet Connections with Auto Uplink™
With its internal 8-port 10/100 switch, the MR814 v3 can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are
autosensing and capable of full-duplex or half-duplex operation.
The router incorporates Auto UplinkTM technology. Each Ethernet port will automatically sense
whether the Ethernet cable plugged into the port should have a ‘normal’ connection such as to a
PC or an ‘uplink’ connection such as to a switch or hub. That port will then configure itself to the
correct configuration. This feature also eliminates the need to worry about crossover cables, as
Auto Uplink will accommodate either type of cable to make the right connection.
Extensive Protocol Support
The MR814 v3 router supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and
Routing Information Protocol (RIP). For further information about TCP/IP, refer to Appendix B,
“Network, Routing, Firewall, and Basics.”
IP Address Sharing by NAT
The MR814 v3 router allows several networked PCs to share an Internet account using only a
single IP address, which may be statically or dynamically assigned by your Internet service
provider (ISP). This technique, known as NAT, allows the use of an inexpensive single-user
ISP account.

A Road Map for ‘How to Get There From Here’
The introduction and adoption of any new technology can be a difficult process. Broadband
Internet service is considered so useful that more and more people want to set up networks in their
home to share a broadband connection. Wireless technology has removed one of the barriers to
networking—running wires. It allows more people to try networking while at the same time
exposes them to the inherent complexity of networking. General networking concepts, setup, and
maintenance can be difficult to understand. In addition, wireless technology adds issues, such as

Note: For
sharing files
and printers on
other types of
computers like
Macintosh or
Linux, refer to
the product
documentation
that came with
those
computers.
1. Use the Windows
Printers and Fax
features to locate
available printers in
the combined
wireless and wired
network in your
home.
2. Use the Windows
Add a Printer wizard
to add access to a
network printer from

you are using to
wirelessly connect
to the network.
3. From the File menu
of an application
such as Microsoft
Word, use the Print

in the network.
Windows computers (wired
and wireless) I am using to
connect to the network
need to be configured with
the Windows Client and

Windows computers (wired
and wireless) I am using to
connect to the network
need to be configured with
the same Windows
Workgroup or Domain
settings as the other
Windows computers in the
combined wireless and
wired network.
Any Windows networking
security access rights such
as login user name/
password that have been
assigned in the Windows
network must be provided
when Windows prompts for
such information.
If so-called Windows ‘peer
networking is being used,
the printer needs to be
enabled for sharing.
Windows Domain settings are
usually managed by corporate
computer support groups.
Windows Workgroup settings
are commonly managed by
individuals who want to set up
small networks in their homes, or
small offices.
For assistance with setting up
Windows networking, refer to the
PC Networking Tutorial on the
MR814 v3 Resource CD
(2230-10095-01 ) and the Help
information provided in the
Windows system you are using.
