How to clone a MAC address
On any home network, each network device has a unique
MAC
(Media Access
Control) address. Some ISPs register the MAC address of the device (usually a
router or a computer) connected directly to the modem. If your computer’s
MAC address is registered with your ISP and you do not want to re-register
the MAC address, then you can
clone
the address (assign the registered MAC
address of your previous device to your new router). If you want to use the
MAC address from an old router that you are replacing with your new router,
you should first determine the MAC address of your old router, then manually
enter it into your new router.
NOTE
For many ISPs that provide dynamic IP addresses automatically, the
stored MAC address in the modem is reset each time you reset the
modem. If you are installing this router for the first time, reset your
modem before connecting the router to your modem. To reset your
modem, disconnect power for about one minute, then reconnect
power.
To clone a MAC address from your computer:
1.
Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-
Fi” on page 7.
2.
Under
Router Settings
, click
Connectivity
. The
Connectivity
page opens.
3.
Click the
Internet Settings
tab.
4.
Under
MAC Address Clone
, click
Enabled
.
5.
Enter the 12-digit MAC address of your old router, then click
OK
.
How to connect to your corporate office
using a VPN
What is a VPN, and do I need to change my router settings?
A
VPN
(Virtual
Private Network) is a network that uses a public network, such as the Internet,
to provide secure communications between a remote computer and another
network. Corporations often provide VPN access to their networks to enable
employees to work from remote offices or while traveling. Most corporate VPNs
use the Internet to provide connectivity between remote employees and the
corporate network.
For a typical VPN, the corporation installs a VPN gateway on their corporate
network. Employees authorized to work remotely connect to the VPN gateway
through the Internet using VPN software and security methods provided by
their employers. Robust security and authentication schemes ensure a secure
connection and access by only authorized users.
The default VPN settings in your router have been configured to pass through
(allow) the most common types of VPN protocols, so usually no changes are
needed.
To change your VPN passthrough settings:
1.
Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-
Fi” on page 7.
2.
Under
Router Settings
, click
Security
. The
Security
page opens to the
Firewall
tab.

•
IPSec Passthrough
–
IPSec
(Internet Protocol Security) is a suite of
protocols used to implement secure exchange of packets at the IP
layer. The VPN clients on the local network can establish an IPSec VPN
tunnel through the router. This option is enabled by default.
•
PPTP Passthrough
–
PPTP
(Point-to-Point Tunneling Protocol) allows
the
PPP
(Point-to-Point Protocol) to be tunneled through an IP network.
The VPN clients on the local network can establish a PPTP VPN tunnel
through the router. This option is enabled by default.
•
L2TP Passthrough
–
L2TP
(Layer 2 Tunneling Protocol) enables point-
to-point sessions using the Internet on the Layer 2 level. The VPN
clients on the local network can establish an L2TP VPN tunnel through
the router. This option is enabled by default.

How to optimize your router for gaming
and voice
How does my router prioritize traffic to the Internet?
Your router can
prioritize traffic between your network and the Internet. Performance for
demanding, real-time applications, such as online gaming, VoIP calls, video
streaming, and videoconferencing, can be improved by configuring
media
prioritization
.
Prioritization settings are applied only to traffic that is uploaded to the Internet.
The router cannot control the quality of the traffic after it reaches the Internet.
TIP
For more information on optimizing your router for online gaming,
see “Port Forwarding and Port Triggering” on page 43.
To configure media prioritization:
1.
Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-
Fi” on page 7.
2.
Under
Apps
, click
Media Prioritization
. The
Media Prioritization
screen
opens.
3.
Turn on
Prioritization
if it is not already on.
4.
Click and drag high-priority devices from the
Normal Priority
list to the
High Priority
list.

5.
To prioritize an application or game, select the name in the drop-down
list, then click and drag the
icon next to the name to the
High
Priority
list.
•
If the application name isn’t listed, click
Edit
and add the name.
TIP
If you want to add a new application or game, you need
to know its port and protocol information (see the
application or game’s documentation for help).
6.
Click
Settings
. The
Settings
screen opens.
a.
Set the maximum
Downstream Bandwidth
. If you set the bandwidth
lower than the actual bandwidth of your router, performance may be
limited.
b.
Set the maximum
Upstream Bandwidth
.
c.
To help manage traffic priority with devices that support WMM, turn
on
WMM Support
.
TIP
WMM
(Wi-Fi MultiMedia) Support is a wireless feature
based on the IEEE 802.11e standard. WMM improves
quality for audio, video, and voice applications by
prioritizing wireless traffic. This feature requires that the
wireless client devices in your network also support WMM.
d.
To have the router re-send data if an error occurs, turn off
No
Acknowledgement
.
CAUTION
If you specify a maximum bandwidth that is too high, the
router cannot apply priorities correctly, and prioritization
problems may result.

How to enable Voice over IP on your
network
Do I need to configure Voice over IP?
VoIP
(Voice over Internet Protocol) is a
technology for using the Internet as an interface for telephone communications.
To use VoIP, you need to get an account with a VoIP service provider. The VoIP
service provider typically provides you with a telephone adapter that connects
to your network. If you do not use your network to make phone calls, you don’t
need to change the default settings.
The
Application Layer Gateway SIP
(Session Initiation Protocol) allows SIP
packets, used by some VOIP service providers, to get through your router’s
firewall.
Page 39 / 61

STUN
(Session Traversal Utilities for NAT),
TURN
(Traversal Using Relay NAT), or
ICE
(Interactive Connectivity Establishment), deselect the
SIP
checkbox.
NOTE
You may need to contact your VoIP service provider to determine
the type of NAT traversal configuration they use.
How to configure UPnP
What is UPnP?
UPnP
(Universal Plug and Play) allows devices connected

How to use a router as an access point
How can I use this new router as an access point?
If you have a large area to
cover with your wireless signal, or if part of your home has weak signals due to
interference, you can use this router to extend the range of your old router’s
wireless network.
To set up your new router as an access point:
1.
Use a network cable to connect this router’s
Internet
port to the
Ethernet
or
LAN
port on the router that is connected to your modem.
2.
Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-
Fi” on page 7.
3.
Under
Router Settings
, click
Connectivity
, then click the
Internet
Settings
tab.
4.
Click
IPv4
.
5.
For
Type of Internet Connection
, select
Bridge Mode
.
6.
Click
Obtain an IPv4 address automatically
, then click
OK
. The new
router’s LAN IP address will be changed and obtained from the router
that is connected to your modem.
How can I use my old router as an access point?
If you have a large area to
cover with your wireless signal, or if part of your home has weak signals due to
interference, you can use your old router to extend the range of your wireless
network. This is a complex process, so this procedure assumes that you have
some networking knowledge.
TIP
Check the documentation for your old router. Some brands of
routers include either a switch on the outside of the case or a
software option to convert it to an access point. If either of these
options is available, follow your old router’s instructions to convert
it to an access point.
You need to take note of your new router’s settings, then apply some of those
settings to the old router so it can work as an access point.
To view your new router’s settings:
1.
Make sure that your new router is connected to the Internet.
2.
Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-
Fi” on page 7.
3.
Under
Router Settings
, click
Wireless
, then take note of the
Network
name (SSID)
,
Password
,
Security mode
, and
Channel
.
4.
Under
Router Settings
, click
Connectivity
, then click the
Local Network
tab. Take note of the DHCP server’s IP address range (192.168.1.100 to
192.168.1.149 by default)
To use your old router as an access point:
1.
With your computer connected to your old router, log into its browser-
based administration utility.
NOTE
Save your changes after finishing each step below.
2.
Open the setup page for the local network (LAN).
3.
In the
Router IP address
field, enter an unused IP address for the LAN
network of your new router.
For example, if your new router has an IP address of 192.168.1.1, you
should choose an IP address on the 192.168.1.0 network. You can choose
any address within the range of 192.168.1.2 to 192.168.1.254. You should
exclude addresses in the range that will be used by the DHCP Server of
your new router (192.168.1.100 to 192.168.1.149). A safe choice might be
192.168.1.250. Take note of this address, because this will be the address
that you will use to manage your old router in the future.
4.
In the
Subnet Mask
field, enter
255.255.255.0
or, if available, select that
subnet mask from a drop-down list.
5.
Disable the DHCP server on your old router. (Because your old router will
be operating as an access point instead of a router, you don’t want it to
distribute IP addresses. There should be only one active DHCP server on
your network, and that should be your new router.)
