How to get the most out of your dual-
band router
I bought a dual band router, but I’m not sure that I’m getting the most
out of it. What should I check?
Of the many reasons for owning a dual-band
router, the most common is to ensure available bandwidth for streaming high-
definition video. At the same time, owners want to make sure that their video
streams won’t be interrupted by other wireless network traffic. To get the most
out of your dual-band router, you can:
•
Upgrade your wireless clients
•
Split your traffic
Upgrade your wireless clients
If you have network adapters that support only legacy wireless network
standards such as 802.11b, you should consider upgrading them with
Wireless-N (802.11n) network adapters. Wireless-B (802.11b) devices can slow
your entire wireless network. For the best performance, all of your wireless
devices should support Wireless-N. You can then select
Wireless-N Only
as your
Network Mode below.
NOTE
If you select
Wireless-N Only
, you may need to temporarily change
your network settings to Mixed to provide access to guests without
Wireless-N networking.
Split your traffic
The best way to improve your multimedia wireless performance is to split your
wireless traffic between your router’s two bands (ranges of radio frequencies).
Your router supports the 2.4 GHz band and the 5 GHz band, and handles the
two bands as two separate wireless networks to help manage the traffic.
The most common way to split wireless traffic is to use the 2.4 GHz band for
basic Internet tasks such as web browsing, email, and downloads, and use
the 5.0 GHz band for streaming multimedia. There are several reasons for this
approach:
•
Although the 2.4 GHz band may be more crowded with wireless traffic
from your neighbors, it’s fine for basic Internet traffic that is not time-
sensitive (such as e-mail).
•
Even though you are connected to your own wireless network, you are
still sharing “air time” with nearby networks.
•
The 5 GHz band is much less crowded than the 2.4 GHz band, so it’s ideal
for streaming multimedia.
•
The 5 GHz band has more available channels, so it is more likely that you
will have your own, interference-free channel for your wireless network.
By default, your dual-band router uses the same network name on both the
2.4 GHz band and the 5 GHz band. The easiest way to segment your traffic is to
rename one of your wireless networks. With a separate, descriptive name, it will
be easy to connect to the right network.
To reconfigure your wireless network:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Wireless
. The
Wireless
page opens to the
Wireless
tab.
3.
Click
Edit
next to the network band you want to modify. Change any of
the settings below:
a.
Enabled
—Deselect this checkbox to disable the network band.
b.
Network name (SSID)
—You can provide a unique SSID for each band
of your wireless network. The name must not exceed 32 characters.
c.
Password
—You can provide a unique password for each band of
your wireless network.

d.
Network mode
—Your choice depends upon the clients that will
connect to your network. If all of your devices are Wireless-N capable,
you can select
Wireless-N Only
for either or both bands.
On the 2.4 GHz band, you can select:
•
Mixed
•
Wireless-B/G Only
(not available on the EA6500)
•
Wireless-N Only
•
Wireless-G Only
•
Wireless-B only
(not available on the EA6500)
On the 5 GHz band, you can select:
•
Mixed
(default), which accepts connections from 802.11a or
802.11n clients
•
Wireless-N Only
(802.11n only)
•
Wireless-A Only
(802.11a only) (not available on the EA6500)
•
Wireless-AC Only
(EA6500 only)
e.
Security mode
—You can set up different security options for the
5 GHz and 2.4 GHz networks. If the security mode you select requires
a passphrase, a
Passphrase
field appears, and you must enter a
passphrase. You can select:
•
None
(no security)
•
WEP
•
WPA Personal
•
WPA Enterprise
•
WPA2 Personal
•
WPA2 Enterprise
•
WPA2/WPA Mixed Personal
•
WPA2/WPA Mixed Enterprise
TIP
Wireless-N networks should use the
WP2-Personal
security
mode for best performance.
f.
Channel width
—We recommend that you keep the default (Auto)
setting for each band. In
Auto
mode, the router and the network
clients automatically switch to the
40 MHz
mode if:
•
Your wireless clients support the 40  MHz mode (sometimes
called
Bonded
mode) in which two 20 MHz channels are bonded
together for better performance.
•
There is no adjacent interference.
With more available channels and less chance of interference on the
5 GHz band, you have the option to force the 40 MHz mode.
On the 2.4 GHz band, you can select:
•
Auto (20 MHz or 40 Mhz)
•
20 MHz Only
On the 5 GHz band, you can select:
•
Auto (automatically selects from the options below)
•
20 MHz Only
•
40 MHz Only
•
80 MHz Only
(EA6500 only)
g.
Channel
—Choose the operating channel for each band. Your
router will automatically select the channel with the least amount
of interference if you leave the default
Auto
setting. We recommend
keeping the default settings for both bands.
h.
SSID broadcast
—(not available on the EA6500) When wireless
clients look for wireless networks to connect to, they detect the
SSID
(wireless network name) broadcast by the router. In other words,
anyone within range of your network can see your network name.
To broadcast your router’s SSID, keep the default setting (Enabled).
If you do not want to broadcast the router’s SSID, deselect the
SSID
broadcast
checkbox. We recommend keeping the default setting
(
Enabled
) for both bands.

How to control access to your network
Why would I need to control access to my wireless network?
If you used
the Setup CD to install your router, your wireless network is already secure. By
default, Setup enables industry-standard
WPA
(Wi-Fi Protected Access) security
using WPA2/WPA mixed mode. If you set up your wireless network manually
and have not enabled wireless security, your wireless network will be an “open”
network that almost anyone nearby with a Wi-Fi-enabled device could access.
What is MAC filtering?
If you choose not to use the built-in security features
of your router, you can still control access to your wireless network using
MAC filtering. Every network device has a unique, 12-digit
MAC
(Media
Access Control) address. Using MAC filtering, you can allow only known MAC
addresses (known devices) onto your network. You can also exclude specific
MAC addresses or deny them access to your wireless network.
TIP
MAC filtering is not strong security. The best way to secure your
network is to use the router’s WPA2 security setting.
Example
: Because each MAC filtering configuration is unique, the following
procedure uses the simplified example of setting up MAC filtering to allow one
wireless device access to the network.
TIP
You can also use MAC filtering to prevent specific PCs from
accessing your network by selecting
Deny
. However, it’s easier
to select
Allow
to permit only known devices than to exclude
unknown devices.
To set up MAC filtering to allow one wireless device access to your
network:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Wireless
. The Wireless page opens.
3.
Click the
MAC Filtering
tab.
4.
Select
Enabled
next to
MAC Filters
, then select
Allow access for ONLY
the listed MAC addresses
.
5.
Click
Add MAC Address
, then enter the MAC address into the
MAC Filter
List
and click
Save
.

How to improve security using the built-in firewall
Why would I need to change my security settings?
By default, the firewall
settings in your router have been optimized for most home environments, so
no changes are needed. The
SPI
(Stateful Packet Inspection) firewall is enabled
by default. In addition, anonymous Internet requests and IDENT requests are
filtered by default. All web filters are disabled, because enabling them may
cause problems for sites that depend on ActiveX controls, Java, or cookies.
Changing firewall settings
To change your firewall settings:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Security
. The
Security
page opens to the
Firewall
tab.
3.
You can now change the following settings:
TIP
For more descriptions of each setting, click
Help
at the top of the
screen.
•
Firewall: SPI firewall protection
—This helps protect your local
network from Internet threats. This option is enabled by default.
On some router models, this setting is separated into IPv6 and IPv4
options so that each can be handled separately.
CAUTION
To help protect your network, you should keep this option enabled.
•
VPN Passthrough:
•
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.
•
Internet filters:
•
Filter anonymous Internet requests
—This filter blocks Internet
requests from unknown sources such as ping requests. This option
is enabled by default.
•
Filter multicast
—Multicasting allows a single transmission
to simultaneously reach specific recipients within your local
network. Select this option to block multicasting. This option is
disabled by default.
•
Filter Internet NAT redirection
—This filter prevents a local
computer from using a URL or Internet IP address to access the
local server. Select this option to enable the filter. This option is
disabled by default. On some router models, this setting applies
to IPv4 Internet only.
•
Filter ident (Port 133)
—This filter prevents port 133 from being
scanned by devices from the Internet. This option is enabled by
default.
