Installing the Router
1. Reset button: resets the router as if you power cycled the unit. Use a
pointed non-metallic object to press this button and hold it for more
than one second but less than five seconds.
Note: If you hold the Reset button for more than five seconds, the
router will be reset to the factory default settings and will restart. Do
not perform a factory reset unless you expressly guided to do so by
Spectrum customer service.
2. WPS Button: begins associating the router with a wireless device.
3. Ethernet (1 - 4): connectors for use with a computer LAN port or
another Ethernet-connected device.
4. Internet: connector to the Spectrum modem.
5. USB: USB host connector for use with external USB devices.
6. Power: connector for the power cord.
Selecting an Installation Location
There are a number of factors to consider when choosing a location to
install the router:
•
•
•
•
•
Is an AC outlet available nearby? For best results, the outlet should
not be switched and should be close enough to the router that
extension cords are not required.
Is the modem nearby? Can you easily run cables between the router’s
location and the modem?
If you are connecting devices to the Ethernet ports, can you easily
run cables between the router’s location and those devices?
If you want to install the router on a desktop, is there enough space
on either side to keep the vents clear? Blocking the vents may cause
overheating.
How close are the wireless devices? In general, the router should be
located centrally within the premises, as close as possible to the
location where users will want to access the wireless connection. The
router wireless connection range is typically 100–200 feet (30m–
65m) for 2.4 GHz signals and less for 5 GHz signals. A number of
factors can affect connection range, as described below.
Desktop Mounting Instructions
Position the router so that:
•
Air flows freely around it
RAC2V1A Router User Guide

Installing the Router
•
•
•
The back faces the nearest wall
It will not fall to the floor if bumped or moved
The sides of the unit are not blocked.
Factors Affecting Wireless Range
A number of factors can affect the usable range for wireless
connections.
Increases
range
Decreases
range
•
Locating the unit centrally
•
Creating as much "line-of-sight" as possible with
client devices
•
Metal or concrete walls between the router and other
client devices
•
Large metal appliances, aquariums, or metal cabinets
between the router and other client devices
•
Interference and RF noise (2.4 GHz wireless phones,
microwave ovens, wireless speaker/receiver systems,
or other wireless networks)
•
Placing the router in a cabinet or other enclosed
space
•
Placing the router next to a desktop computer
Notes:
•
•
It may be acceptable to decrease the range of the wireless network,
as long as the decreased range is sufficient for your needs. By
limiting the network’s range, you reduce interference with other
networks and make it harder for unwanted users to find and connect
to the network.
Setting the transmit power level to High increases the range. Setting
it to Medium or Low decreases the range. Medium or Low may be
more appropriate for high-density residential locations.
Ethernet or Wireless?
There are two ways to connect the computer (or other equipment) to
the router. The following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more computers
into a Local Area Network (LAN). You can use the Ethernet connection
RAC2V1A Router User Guide

Installing the Router
if the client device has built-in Ethernet hardware. The router provides
support for up to four such connected devices.
Note: To connect more than four client devices to the router through
the Ethernet ports, you need an Ethernet switch (available at computer
retailers).
The router includes one 3-foot (.9m) Ethernet cable. The enclosed
Ethernet cable is yellow to match the Internet port on the back of the
router, because this cable is primarily intended to connect the router to
the Spectrum modem. You can purchase more cables if necessary at a
computer retailer. If you are connecting the router directly to a
computer, or to an Ethernet switch with a cross-over switch, ask for
Category 5e (CAT5e) straight-through cable. CAT5e cable is required
for gigabit Ethernet (Gig-E), not regular CAT5 cable.
Wireless
Wireless access lets you connect additional (wireless-capable) devices
to the router. The 802.11 wireless LAN standard allows one or more
computers to access the router using a wireless (radio) signal. These
connections are in addition to the connections supported via Ethernet.
Both
If you have two or more clients, you can use Ethernet for up to four
devices and wireless for the others.
Connecting the Router
1. Unplug the power to turn off the modem.
2. Connect one end of the Ethernet cable (included) to the modem, and
the other end to the Internet port on the router.
3. Reconnect the plug on the modem to turn the modem back on. Wait
approximately 2 minutes to allow the modem to fully power up.
RAC2V1A Router User Guide
13
Installing the Router
4. Connect the power adapter (included) to the power connector on
the back of the router, and then connect the power adapter to an
available AC outlet. Wait until the light on the front panel of the
router turns blue and begins to pulse.
5. To manage the setup of the router, you can use a second Ethernet
cable (not provided) to connect a computer to an available LAN port
on the router, or you can connect wirelessly by using the preset
wireless security settings printed on the security label located on the
back of the router.
6. Open a browser on the computer to access the management
interface of the router. If the webpage does not display correctly, try
another browser. See Accessing the Configuration Interface (page 15)
for more information.

Note: Refer to Router Configuration Screen Descriptions (page 28) for
additional advanced configuration options.
Configuring DHCP
DHCP (Dynamic Host Protocol Configuration) is enabled by default on
the router, which allows the router to act as a DHCP server and
automatically assign an IP address to each device on the network.
DHCP is a set of rules used by devices such as a computer, router, or
network adapter to allow the device to request and obtain an IP address
from a server, which maintains a list of addresses available for use. The
DHCP server ensures that all IP addresses are unique, e.g., no IP address
is assigned to a second device while the first device's assignment is valid
(its lease has not expired).
Without DHCP, the IP addresses must be entered manually at each
computer or device and a new IP address must be entered each time it
moves to a new location on the network.
Configuring DHCP for IPv4
Perform the following steps to configure DHCP for IPv4.
1. Access and sign in to the configuration interface.
2. Click the LAN Setup tab.
3. Click LAN Settings (IPv4) in the side menu to display the LAN

Selecting the NAT Mode
NAT (Network Address Translation) allows the router to manipulate IP
addresses so that just one single IP address can represent an entire
group of computers on the network and let them all communicate with
the Internet. This conserves IP addresses and is necessary in IPv4 since
there are a limited number of available IP addresses for use. (This
limitation does not affect the IPv6 address space.)
Perform the following steps to select the NAT Mode.
1. Access and sign in to the configuration interface.
2. Click the LAN Setup tab.
3. Click LAN Settings (IPv4) in the side menu to display the LAN
Settings screen.
4. Select the NAT Mode from the NAT Mode field drop-down list. The
optional modes are:

General Firewall Configuration Settings
The router is equipped with a firewall that will protect your network
from a wide array of common Denial of Service (DoS) attacks, including
Ping of Death (PoD) attacks.
The firewall is enabled by default, but you can choose to disable it.
Turning off the firewall protection will not leave the network completely
vulnerable to hacker attacks, but it is recommended that you enable the
firewall whenever possible.

Port Forwarding
The port forwarding function forwards inbound traffic from the Internet
to a specified single device on your network. Examples include allowing
access to a web server on your network, peer-to-peer file sharing,
applications that allow remote access to a specified computer, some
gaming and videoconferencing applications and others.
If you have a server in the network that you want to make available to
the Internet, you can set up port forwarding. The firewall passes
requests from the Internet to the designated computer on the network.
This function works by allowing you to route external (Internet) calls for
services such as a web server (port 80), FTP server (Port 21), or other
applications through the router to the internal network.

DHCP is a set of rules used by devices such as a
computer, router, or network adapter to allow the
device to request and obtain an IP address from a
server which maintains a list of addresses available
for use.
The DHCP server ensures that all IP addresses are
unique, e.g., no IP address is assigned to a second
device while the first device's assignment is valid
(its lease has not expired).
Without DHCP, the IP addresses must be entered
manually at each computer in an organization, and
a new IP address must be entered each time a
computer moves to a new location on the network.

A "lease" is the amount of time that a given IP

network device. The lease time can vary depending
on how long a user is likely to require the Internet
connection at a particular location. Using very short
leases, DHCP can dynamically reconfigure networks
where there are more computers than available IP
addresses, such as educational environments.

This screen shows the mapping of network name (SSID) priorities and
Differentiated Services Code Point (DSCP) remarking. DSCP specifies
the priority for queueing IP packets before they are forwarded.
For example, you could set the Home as a Hotspot (HaaH) SSID as a
lower priority than the primary SSID to make sure that the owner of the
service always gets priority treatment.
If you select SSID Priority as the classification method, all of the L3
DSCP/ToS values for the transmission packets (LAN/WAN to WLAN)
will be remarked to the same 802.11e QoS control field value.
If you select DSCP Remarking as the classification method, the L3

MAC Filter
MAC address filtering gives you an extra layer of security by allowing
you to specify which devices can access your network. Whenever a new
device tries to join your network, the router checks the MAC address of
the device against a list of approved addresses. You can choose to allow

Troubleshooting
The router is plugged in, but the light is off
Check all power connections. Is the power cord plugged in firmly at
both ends?
If you plugged the power cord into a power strip, make sure the strip is
switched on.
Try to plug the power cord into a different outlet. If the outlet is
controlled by a wall switch, make sure the switch is on.
Finally, check the fuse or circuit breaker panel.
I'm not getting on the Internet (all connections)
It may take several minutes to establish a connection the first time you
power up the router, especially when many people are online. Always
leave the router plugged into AC power and connected to the modem.
Check the light on the front. It should be blue.
Check the cable connections. Connectors should be tight. Cables should
not be pinched, kinked, or bent sharply—any of these can cause a break
or short in the cable. (You may have to replace the cable).
Proceed to the Ethernet or wireless solutions if necessary.
I'm not getting on the Internet (Ethernet)
If you are using a switch, is the switch turned on?
Are you using the right type of Ethernet cable? Use an RJ45 Cat5e cable
for direct connection to a computer; use a cross-over cable for
connection to a switch.
Unplug the power from the router and wait a few seconds, then plug the
power back in.
A misconfiguration could lock out all access to the router. If you think

Troubleshooting
Change the security setting to another setting.
A misconfiguration could lock out all access to the router. If you think
this has happened, see Factory Defaults (page 82).
Make sure that your wireless device is compatible with the wireless
mode that you selected. See Setting the Wireless Mode (page 22).
My wireless Internet connection stops working
sometimes
This may be caused by distance or interference. Try moving the device
closer to the router.
Two common sources of interference are 2.4 GHz “remote” telephones
and microwave ovens. If you cannot remove the interfering product, try
using a different channel.
I can get on the Internet, but everything is slow
If the Web site you are visiting is very popular, that site may be having
trouble servicing all the requests. If other sites download quickly, wait
for a few minutes and try again. Web site traffic during peak hours may
also affect the connection speed.
Other communications on the LAN, or interference with wireless
connections, may slow down the connection.
