Maximum Performance Wireless-N Router ii
Linksys E4200 Chapter 1: Product Overview
Chapter 1: Product Overview
Thank you for choosing the Linksys E4200 Maximum
Performance Wireless-N Router . The router lets you access
the Internet via a wireless connection or through one
of its four switched ports . You can also use the router to
share resources such as computers, printers and files . The
router’s USB port connects to a USB storage device, so you
can add storage space to your network using a USB hard
drive or access your portable files using a USB flash disk .
The router’s media server streams music, video, and photos
from an attached storage device to any UPnP-compatible
media adapter or player .
Various security features help protect your data and your
privacy while you are online . Security features include
Wi-Fi Protected Access 2 (WPA2) security, which
encrypts data on your wireless network; a Stateful Packet
Inspection (SPI) firewall to help block unauthorized access
to your router; and Network Address Translation (NAT)
technology, which enhances network protection by
allowing your computers to share Internet access through
a single, public Internet IP address . (IP stands for Internet
Protocol .)
Setup and use of the router is easy using Cisco Connect,
the software that is installed when you run the included
CD . Advanced configuration of the router is available
through the provided browser-based utility .
For more wireless bandwidth, the router can create two
simultaneous yet separate Wireless-N networks, one
using the 5 GHz radio frequency band and one using the
2 .4 GHz band . For example, use the Wireless-N 2 .4 GHz
network to surf, email, and print while keeping the less
crowded, Wireless-N 5 GHz network free for time-sensitive
traffic like Voice over IP (VoIP) calls, online gaming, and
high-definition video . For more information, refer to
“Simultaneous Networks” on page 10 . The Guest Access
feature allows you to provide Internet access to guests
visiting your home without granting them access to your
local network .

assigned a new dynamic IP address, or the lease will be
renewed . Enter the length of time, in minutes, that a
user will be “leased” a dynamic IP address . The default is
0 minutes, which means one day .
Static DNS 1-3 The Domain Name System (DNS) is how
the Internet translates domain or website names into
Internet addresses or URLs . Your ISP will provide you with at
least one DNS server IP address . If, however, you wish to use
a different DNS server, enter its IP address (you can enter up
to three DNS server IP addresses) . These static DNS server(s)
will have higher priority than the ISP’s DNS servers . The
router will assign these DNS servers to the computers and
other devices in your local network .

registered with your ISP and you do not wish to re-register
the MAC address, then you may assign the registered MAC
address to the router with the MAC Address Clone feature .

NAT
Enabled/Disabled If this Router shares your Internet
connection for your local network, keep the default,
Enabled . When Network Address Translation (NAT) is
disabled, dynamic routing is available .
Dynamic Routing (RIP)
Dynamic routing uses the Routing Information Protocol
(RIP) . This option enables the router to automatically
exchange routing tables with the other router(s) . The
router determines the network packets’ route based on
the fewest number of hops between the source and the
destination .

Simultaneous Networks
For more wireless bandwidth, the router can create two
simultaneous yet separate Wireless-N networks, one using
the 5 GHz radio frequency band and one using the 2 .4 GHz
band . This allows you to isolate higher-priority traffic, such
as online gaming, Voice over Internet Protocol (VoIP) calls,
and video streaming .
For example, in this diagram (“Simultaneous Networks
Diagram” on page 11), the 2 .4 GHz wireless network is
represented by green waves between the router and the
office devices, the wireless printer and notebook . The
5 GHz wireless network is represented by the blue waves
between the router and the living room devices, the
gaming console and media player .
Choose which computers and other wireless devices should
join which network . Wireless-N devices support both the
5 GHz and 2 .4 GHz bands, so they can join either
network . Wireless-G and Wireless-B devices support only
the 2 .4 GHz band, so they should join the 2 .4 GHz network .
Wireless-A devices support only the 5 GHz band, so they
should join the 5 GHz network .
For the 5 GHz network, configure all computers and other
wireless devices with the same 5 GHz Network Name
and wireless security settings . For the 2 .4 GHz network,
configure all computers and other wireless devices with
the same 2 .4 GHz Network Name and wireless security
settings .
NOTE: You should use the same Network
Name for both your 5 GHz and 2 .4 GHz wireless
networks; this allows seamless roaming by
dual-band Wireless-N client devices .
You can use Wi-Fi Protected Setup to set up both
networks, or you can manually configure the router . Wi-Fi
Protected Setup is a feature that makes it easy to set up
your wireless network . If you have client devices, such as
wireless printers, that support Wi-Fi Protected Setup, then
you can use Wi-Fi Protected Setup .

visiting your home with Internet access via wireless . The
guest network is a wireless network separate from your
local network . The Guest Access feature does not provide
access to the local network and its resources, so your
guests will not have access to your computers or personal
data . For example, the guest computer cannot print to a
printer on the local network or copy files to a computer on
the local network . This helps minimize exposure of your
local network .

The router’s USB port lets you connect USB storage that
can be accessed over your network .
When you connect a USB storage device to the router’s
USB port, you can access its content without a password
via Windows Explorer or the Mac Finder . For more
information, go to Appendix B: How to Install and Access
USB Storage, “Overview” on page 49 .
The options on the various Storage screens are available
when a USB storage device is connected to the USB port
of the router . The Disk screen describes the USB disk
currently attached to the router . Use this screen to create
shared folders, safely remove a disk, or format a disk (any

You can use shared folders to manage network access to
the contents on the disk . You can specify individual
folders that you want to share, or you can share the
entire partition . Each shared folder created on the Disk
screen has a unique name (Display Name), is mapped to
a physical folder on the disk, and specifies access rights to
that folder .
Access rights are managed by group and user accounts
that you can create on the Storage > Administration screen
(go to “Storage > Administration” on page 29) . Each user
has his or her own login and belongs to a group . Each
group has either read-and-write or read-only access rights .
NOTE: By default, all content on the disk
can be accessed without a password . If you
want to specify which groups can access
the shared folders, select Disabled for the
Anonymous Disk Access option . Go to “Storage

Quality of Service (QoS) is a method that assigns priority
to specific types of network traffic, which often are
demanding, real-time applications, such as online gaming,
VoIP calls, video streaming, and videoconferencing . QoS
can mark packets to designate different levels of priority,
so it helps to ensure optimal performance for the most
important, real-time applications .
QoS is only applied to traffic streams that are uploaded to
the Internet . QoS cannot be guaranteed after the traffic
streams reach the Internet .

Upstream Bandwidth
The Upstream Bandwidth feature sets the maximum
outgoing bandwidth that applications can use . The
default, Auto, allows the router to set the maximum . The
router sets speeds that are multiples of 512 Kbps . Here are
a couple of examples:
• If the router auto-detects an upstream speed between
512 Kbps and 1024 Kbps, it will set the maximum at
512 Kbps .
• If the router auto-detects an upstream speed of 2300
Kbps, it will set the maximum at 2048 Kbps (512 Kbps
x 4) .
Upstream Bandwidth This option sets the maximum

QoS (Quality of Service)
Wireless
WMM Support The Wi-Fi MultiMedia (WMM) feature is a
wireless QoS feature based on the IEEE 802 .11e standard .
WMM improves quality for audio, video, and voice
applications by prioritizing wireless traffic . To use this
feature, the wireless client devices in your network must
support WMM . To disable this option, select Disabled .
Otherwise, keep the default, Enabled .
No Acknowledgement If you want the router to re-send
data if an error occurs, keep the default, Disabled . If you
do not want the router to re-send data if an error occurs,
select Enabled .
Internet Access Priority
The router is the interface between the local network and
the Internet . The user can configure the router to assign
higher priority for these categories: Applications, Online
Games, MAC Address, and Voice Device .
In this section, you can set the bandwidth priority for a
variety of applications and devices . There are four levels
of priority: High, Medium, Normal, or Low . When you set
priority, do not set all applications to High, because this will
defeat the purpose of allocating the available bandwidth .
If you want to select below-normal bandwidth, select
Maximum Performance Wireless-N Router
NOTE: If the maximum bandwidth is too high,
then the router cannot apply QoS properly, and
there will be adverse QoS issues .
Category
You can define the Internet access priority level for as
many selections as you want . The Summary section will
display all of the priority selections that you enter . Select
from the following categories:
• Applications Allows you to assign a priority level for a
predefined application or one that you add .
• Online Games Allows you to assign a priority level for
a preset game or one that you add .
• MAC Address This option lets you prioritize network
traffic based on the device that is accessing the
network . For example, if you want your gaming
console to have higher priority accessing the Internet
than your computer, you can assign their priority levels
using their respective MAC addresses .
• Voice Device Voice devices require a higher priority
level . You can assign a higher priority level to voice
devices using their respective MAC addresses .
