INTRODUCTION
This chapter introduces the CGNV2 and its GUI (Graphical User Interface).
1.1 CGNV2 OVERVIEW
Your CGNV2 is a voice-enabled cable modem and wireless access point that allows
you to connect your computers, analog telephones, wireless devices, and other
network devices to one another, and to the Internet via the cable connection.
Computers with a wired connection to the CGNV2 are on the Local Area Network
(LAN), computers with a wireless connection to the CGNV2 are on the Wireless Local
Area Network (WLAN) and the CGNV2 connects to the service provider over the
Wide Area Network (WAN).
FIGURE 1: Application Overview

16 HITRON CGNV2 USER’S GUIDE
INTRODUCTION
1.1.1 KEY FEATURES
The CGNV2 provides:
Internet connection to cable modem service via CATV port (F-type RF
connector)
Voice over IP (VoIP) connection to your voice service provider.
Local Area Network connection via four 10/100/1000 Mbps (megabits per
second) Ethernet ports
Dynamic Host Configuration Protocol (DHCP) for devices on the LAN
LAN troubleshooting tools (Ping and Traceroute)
IEEE 802.11b/g/n wireless MIMO (Multiple-In, Multiple-Out) networking, allowing
speeds of up to 300Mbps
Wireless security: WEP, WPA-PSK and WPA2-PSK encryption, WiFi Protected
Setup (WPS) push-button and PIN configuration and MAC filtering
Wired security: stateful inspection firewall with intrusion detection system, IP and
MAC filtering, port forwarding and port triggering, and De-Militarized Zone
(DMZ)
Parental control: scheduled website blocking and access logs
Settings backup and restore
Secure configuration interface, accessible by Web browser
1.2 HARDWARE CONNECTIONS
This section describes the CGNV2’s physical ports and buttons.

INTRODUCTION
FIGURE 2: Hardware Connections
TABLE 1: Hardware Connections
WPS Use this button to turn the wireless network on or off,
and to begin the WiFi Protected Setup (WPS) Push-
Button Configuration (PBC) procedure (see WPS on
page 79 for more information.)
To turn the wireless network on or off, press the
button for between one and five seconds.
To begin the WPS PBC connection procedure, press
and hold the button for between five and ten
seconds. Press the PBC button on your wireless
clients in the coverage area within two minutes to
enable them to join the wireless network.
Reset Use this button to reboot or reset your CGNV2.
Press the button and hold it for less than five
seconds to reboot the CGNV2. The CGNV2 restarts,
using your existing settings.
Press the button and hold it for more than ten
seconds to delete all user-configured settings and
restart the CGNV2 using its factory default settings.

INTRODUCTION
1.3 LEDS
This section describes the CGNV2’s LEDs (lights).
LAN1 Use these ports to connect your computers and other
network devices, using Category 5 or 6 Ethernet cables
with RJ45 connectors.
LAN2
LINE Use this port to connect your analog phones for VoIP
services, using cables with RJ11 connector.
CABLE Use this to connect to the Internet via an F-type RF
cable.
POWER Use this to connect to the 12v/2A power adapter that
came with your CGNV2.
NEVER use another power adapter with
your CGNV2. Doing so could harm your
CGNV2.

TABLE 2: LEDs
LED STATUS DESCRIPTION
WIRELESS Off No data is being transmitted or received over the
wireless network.
Blinking Data is being transmitted or received over the
wireless network.
LINE Off Your service plan does not include voice service.
Blinking A telephone is connected to the relevant Line port,
and is off-hook.
On Your service plan includes voice service.
ETH Off No device is connected to any LAN port.
Blinking A device is connected to a LAN port via a fast
Ethernet link, and is transmitting or receiving data.
On A device is connected to a LAN port via a fast
ethernet link, but is not transmitting or receiving
data.
Status Blinking The CGNV2’s cable modem is registering with the
service provider.
On The CGNV2’s cable modem has successfully
registered with the service provider.

INTRODUCTION
When you turn on the CGNV2, the LEDs light up in the following order:
Power
US
DS
Status
The ETH 1~2 LEDs light up as soon as there is activity on the relevant port, the
LINE port light up if your service contract includes voice service, and the
WIRELESS LED lights up once the wireless network is ready.
1.4 IP ADDRESS SETUP
Before you log into the CGNV2’s GUI, your computer’s IP address must be in the
same subnet as the CGNV2. This allows your computer to communicate with the
CGNV2.
NOTE: See IP Addresses and Subnets on page 25 for background information.
The CGNV2 has a built-in DHCP server that, when active, assigns IP addresses to
computers on the LAN. When the DHCP server is active, you can get an IP address
automatically. The DHCP server is active by default.
If your computer is configured to get an IP address automatically, or if you are not
sure, try to log in to the CGNV2 (see Login to the CGNV2 on page 22).
If the login screen displays, your computer is already configured correctly.
If the login screen does not display, either the CGNV2’s DHCP server is not
active or your computer is not configured correctly. Follow the procedure in
Manual IP Address Setup on page 21 and set your computer to get an IP
address automatically. Try to log in again. If you cannot log in, follow the manual
IP address setup procedure again, and set a specific IP address as shown. Try
to log in again.
US Blinking The CGNV2 is searching for an upstream frequency
on the CATV connection.
On The CGNV2 has successfully located and locked
onto an upstream frequency on the CATV
connection.
DS Blinking The CGNV2 is searching for a downstream
frequency on the CATV connection.
On The CGNV2 has successfully located and locked
onto a downstream frequency on the CATV
connection.
POWER On The CGNV2 is receiving power.
Off The CGNV2 is not receiving power.
