RAC2V1A Router User Guide 10
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 11
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
• Locating the unit centrally
• Creating as much "line-of-sight" as possible with
client devices
Decreases
range
• 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 12
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.

Advanced Configuration Options
This section explains how to use the most common advanced
configuration options for the router in the following areas:
• LAN Setup
• Wireless Setup
• Firewall
• Utilities
Note: Refer to
additional advanced configuration options.
Router Configuration Screen Descriptions
(page 28) for
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.

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.
Perform the following steps if you have disabled the firewall and want to
enable it again.
1. Access and sign in to the configuration interface.
2. Click the Firewall tab.

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.
Perform the following steps to set up port forwarding.
1. Access and sign in to the configuration interface.
2. Click the Firewall tab.

Configuring DMZ for Gaming or Conferencing Applications
The DMZ feature allows you to specify one computer on the network to
be placed outside of the NAT firewall. This may be necessary if the NAT
feature is causing problems with an application such as a game or video
conferencing application.
Use this feature only on a temporary basis. The computer in the DMZ is
not protected from hacker attacks.
Perform the following steps to put a computer in the DMZ.
