HITRON CVE-30360 USER’S GUIDE
INTRODUCTION
The CVE-30360 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 CVE-30360 (see Logging into the CVE-30360 on page 13).
If the login screen displays, your computer is already configured correctly.
If the login screen does not display, either the CVE-30360’s DHCP server is not
active or your computer is not configured correctly. Follow the procedure in
Manual IP Address Setup on page 12 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.
NOTE: If you still cannot see the login screen, your CVE-30360’s IP settings may
have been changed from their defaults. If you do not know the CVE-30360’s
new address, you should return it to its factory defaults. See Resetting the
CVE-30360 on page 14. Bear in mind that ALL user-configured settings are
lost.
1.4.1 MANUAL IP ADDRESS SETUP
By default, your CVE-30360’s local IP address is 192.168.0.1. If your CVE-30360 is
using the default IP address, you should set your computer’s IP address to be
between 192.168.0.2 and 192.168.0.254.
NOTE: If your CVE-30360 DHCP server is active, set your computer to get an IP
address automatically in step 5. The CVE-30360 assigns an IP address to
your computer. The DHCP server is active by default.
Take the following steps to manually set up your computer’s IP address to connect to
the CVE-30360:
NOTE: This example uses Windows XP; the procedure for your operating system
may be different.
1 Click Start, then click Control Panel.
2 In the window that displays, double-click Network Connections.
3 Right-click your network connection (usually Local Area Connection) and click
Properties.
4 In the General tab’s This connection uses the following items list, scroll
down and select Internet Protocol (TCP/IP). Click Properties.
5 You can get an IP address automatically, or specify one manually:
22 HITRON CVE-30360 USER’S GUIDE
INTRODUCTION
If your CVE-30360’s DHCP server is active, select Get an IP address
automatically.
If your CVE-30360’s DHCP server is not active, select Use the following IP
address. In the IP address field, enter a value between 192.168.0.2 and
192.168.0.254 (default). In the Subnet mask field, enter 255.255.255.0
(default).
NOTE: If your CVE-30360 is not using the default IP address, enter an IP address
and subnet mask that places your computer in the same subnet as the CVE-
30360.
6 Click OK. The Internet Protocol (TCP/IP) window closes. In the Local Area
Connection Properties window, click OK.
Your computer now obtains an IP address from the CVE-30360, or uses the IP
address that you specified, and can communicate with the CVE-30360.
1.5 LOGGING INTO THE CVE-30360
Take the following steps to log into the CVE-30360’s GUI.
NOTE: You can log into the CVE-30360’s GUI via the wireless interface. However, it
is strongly recommended that you configure the CVE-30360 via a wired

CABLE

CABLE
This chapter describes the screens that display when you click Cable in the toolbar.
2.1 CABLE OVERVIEW
This section describes some of the concepts related to the Cable screens.
2.1.1 DOCSIS
The Data Over Cable Service Interface Specification (DOCSIS) is a
telecommunications standard that defines the provision of data services) Internet
access) over a traditional cable TV (CATV) network.
Your CVE-30360 supports DOCSIS version 3.0.
2.1.2 IP ADDRESSES AND SUBNETS
Every computer on the Internet must have a unique Internet Protocol (IP) address.
The IP address works much like a street address, in that it identifies a specific
location to which information is transmitted. No two computers on a network can have
the same IP address.
2.1.2.1 IP ADDRESS FORMAT
IP addresses consist of four octets (8-bit numerical values) and are usually
represented in decimal notation, for example 192.168.1.1. In decimal notation, this
means that each octet has a minimum value of 0 and a maximum value of 255.
An IP address carries two basic pieces of information: the “network number” (the
address of the network as a whole, analogous to a street name) and the “host ID”
(analogous to a house number) which identifies the specific computer (or other
network device).
2.1.2.2 IP ADDRESS ASSIGNMENT
IP addresses can come from three places:
The Internet Assigned Numbers Agency (IANA)
26
HITRON CVE-30360 USER’S GUIDE
CABLE
Your Internet Service Provider
You (or your network devices)
IANA is responsible for IP address allocation on a global scale, and your ISP assigns
IP addresses to its customers. You should never attempt to define your own IP
addresses on a public network, but you are free to do so on a private network.
In the case of the CVE-30360:
The public network (Wide Area Network or WAN) is the link between the cable
(CATV) connector and your Internet Service Provider. Your CVE-30360’s IP
address on this network is assigned by your service provider.
The private network (in routing mode - see Routing Mode on page 28) is your
Local Area Network (LAN) and Wireless Local Area Network (WLAN), if
enabled. You are free to assign IP addresses to computers on the LAN and
WLAN manually, or to allow the CVE-30360 to assign them automatically via
DHCP (Dynamic Host Configuration Protocol). IANA has reserved the following
blocks of IP addresses to be used for private networks only:
If you assign addresses manually, they must be within the CVE-30360’s LAN
subnet.
2.1.2.3 SUBNETS
A subnet (short for sub-network) is, as the name suggests, a separate section of a
network, distinct from the main network of which it is a part. A subnet may contain all
of the computers at one corporate local office, for example, while the main network
includes several offices.
In order to define the extent of a subnet, and to differentiate it from the main network,
a subnet mask is used. This “masks” the part of the IP address that refers to the main
network, leaving the part of the IP address that refers to the sub-network.
Each subnet mask has 32 bits (binary digits), as does each IP address:
A binary value of 1 in the subnet mask indicates that the corresponding bit in the
IP address is part of the main network.
A binary value of 0 in the subnet mask indicates that the corresponding bit in the
IP address is part of the sub-network.

HITRON CVE-30360 USER’S GUIDE
CABLE
For example, the following table shows the IP address of a computer (192.168.1.1)
expressed in decimal and binary (each cell in the table indicates one octet):
The following table shows a subnet mask that “masks” the first twenty-four bits of the
IP address, in both its decimal and binary notation.
This shows that in this subnet, the first three octets (192.168.1, in the example IP
address) define the main network, and the final octet (1, in the example IP address)
defines the computer’s address on the subnet.
The decimal and binary notations give us the two common ways to write a subnet
mask:
Decimal: the subnet mask is written in the same fashion as the IP address:
255.255.255.0, for example.
Binary: the subnet mask is indicated after the IP address (preceded by a forward
slash), specifying the number of binary digits that it masks. The subnet mask
255.255.255.0 masks the first twenty-four bits of the IP address, so it would be
written as follows: 192.168.1.1/24.
2.1.3 DHCP
The Dynamic Host Configuration Protocol, or DHCP, defines the process by which IP
addresses can be assigned to computers and other networking devices
automatically, from another device on the network. This device is known as a DHCP
server, and provides addresses to all the DHCP client devices.
In order to receive an IP address via DHCP, a computer must first request one from
the DHCP server (this is a broadcast request, meaning that it is sent out to the whole
network, rather than just one IP address). The DHCP server hears the requests, and
responds by assigning an IP address to the computer that requested it.
If a computer is not configured to request an IP address via DHCP, you must
configure an IP address manually if you want to access other computers and devices
on the network. See IP Address Setup on page 20 for more information.
By default, the CVE-30360 is a DHCP client on the WAN (the CATV connection). It
broadcasts an IP address over the cable network, and receives one from the service
provider. By default, the CVE-30360 is a DHCP server on the LAN; it provides IP
addresses to computers on the LAN which request them.

HITRON CVE-30360 USER’S GUIDE
CABLE
2.1.4 DHCP LEASE
“DHCP lease” refers to the length of time for which a DHCP server allows a DHCP
client to use an IP address. Usually, a DHCP client will request a DHCP lease
renewal before the lease time is up, and can continue to use the IP address for an
additional period. However, if the client does not request a renewal, the DHCP server
stops allowing the client to use the IP address.
This is done to prevent IP addresses from being used up by computers that no longer
require them, since the pool of available IP addresses is finite.
2.1.5 MAC ADDRESSES
Every network device possesses a Media Access Control (MAC) address. This is a
unique alphanumeric code, given to the device at the factory, which in most cases
cannot be changed (although some devices are capable of “MAC spoofing”, where
they impersonate another device’s MAC address).
MAC addresses are the most reliable way of identifying network devices, since IP
addresses tend to change over time (whether manually altered, or updated via
DHCP).
Each MAC address displays as six groups of two hexadecimal digits separated by
colons (or, occasionally, dashes) for example 00:AA:FF:1A:B5:74.
NOTE: Each group of two hexadecimal digits is known as an “octet”, since it
represents eight bits.
Bear in mind that a MAC address does not precisely represent a computer on your
network (or elsewhere), it represents a network device, which may be part of a
computer (or other device). For example, if a single computer has an Ethernet card
(to connect to your CVE-30360 via one of the LAN ports) and also has a wireless
card (to connect to your CVE-30360 over the wireless interface) the MAC addresses
of the two cards will be different. In the case of the CVE-30360, each internal module
(cable modem module, Ethernet module, wireless module, etc.) possesses its own
MAC address.
2.1.6 ROUTING MODE
When your CVE-30360 is in routing mode, it acts as a gateway for computers on the
LAN to access the Internet. The service provider assigns an IP address to the CVE-
30360 on the WAN, and all traffic for LAN computers is sent to that IP address. The
CVE-30360 assigns private IP addresses to LAN computers (when DHCP is active),
and transmits the relevant traffic to each private IP address.
NOTE: When DHCP is not active on the CVE-30360 in routing mode, each computer
on the LAN must be assigned an IP address in the CVE-30360’s subnet
manually.
29
HITRON CVE-30360 USER’S GUIDE
CABLE
When the CVE-30360 is not in routing mode, the service provider assigns an IP
address to each computer connected to the CVE-30360 directly. The CVE-30360
does not perform any routing operations, and traffic flows between the computers and
the service provider.
Routing mode is not user-configurable; it is specified by the service provider in the
CVE-30360’s configuration file.
2.1.7 CONFIGURATION FILES
The CVE-30360’s configuration (or config) file is a document that the CVE-30360
obtains automatically over the Internet from the service provider’s server, which
specifies the settings that the CVE-30360 should use. It contains a variety of settings
that are not present in the user-configurable Graphical User Interface (GUI) and can
be specified only by the service provider.
2.1.8 DOWNSTREAM AND UPSTREAM TRANSMISSIONS
The terms “downstream” and “upstream” refer to data traffic flows, and indicate the
direction in which the traffic is traveling. “Downstream” refers to traffic from the
service provider to the CVE-30360, and “upstream” refers to traffic from the CVE-
30360 to the service provider.
2.1.9 CABLE FREQUENCIES
Just like radio transmissions, data transmissions over the cable network must exist
on different frequencies in order to avoid interference between signals.
The data traffic band is separate from the TV band, and each data channel is
separate from other data channels.
2.1.10 MODULATION
Transmissions over the cable network are based on a strong, high frequency periodic
waveform known as the “carrier wave.” This carrier wave is so called because it
“carries” the data signal. The data signal itself is defined by variations in the carrier
wave. The process of varying the carrier wave (in order to carry data signal
information) is known as “modulation.” The data signal is thus known as the
“modulating signal.”
Cable transmissions use a variety of methods to perform modulation (and the
“decoding” of the received signal, or “demodulation”). The modulation methods
defined in DOCSIS 3 are as follows:
QPSK: Quadrature Phase-Shift Keying
QAM: Quadrature Amplitude Modulation
QAM TCM: Trellis modulated Quadrature Amplitude Modulation
30
HITRON CVE-30360 USER’S GUIDE
CABLE
In many cases, a number precedes the modulation type (for example 16 QAM). This
number refers to the complexity of modulation. The higher the number, the more data
can be encoded in each symbol.
NOTE: In modulated signals, each distinct modulated character (for example, each
audible tone produced by a modem for transmission over telephone lines) is
known as a symbol.
Since more information can be represented by a single character, a higher number
indicates a higher data transfer rate.
2.1.11 TDMA, FDMA AND SCDMA
Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA)
and Synchronous Code Division Multiple Access (SCDMA) are channel access
methods that allow multiple users to share the same frequency channel.
TDMA allows multiple users to share the same frequency channel by splitting
transmissions by time. Each user is allocated a number of time slots, and
transmits during those time slots.
FDMA allows multiple users to share the same frequency channel by assigning a
frequency band within the existing channel to each user.
SCDMA allows multiple users to share the same frequency channel by assigning
a unique orthogonal code to each user.

LAN
This chapter describes the screens that display when you click LAN in the toolbar.
3.1 LAN OVERVIEW
This section describes some of the concepts related to the LAN screens.
3.1.1 LOCAL AREA NETWORKS
A Local Area Network (LAN) is a network of computers and other devices that usually
occupies a small physical area (a single building, for example). Your CVE-30360’s
LAN consists of all the computers and other networking devices connected to the
LAN 1~4 ports. This is your private network (in routing mode - see Routing Mode on
page 28).
The LAN is a separate network from the Wide Area Network (WAN). In the case of
the CVE-30360, the WAN refers to all computers and other devices available on the
cable (CATV) connection.
By default, computers on the WAN cannot identify individual computers on the LAN;
they can see only the CVE-30360. The CVE-30360 handles routing to and from
individual computers on the LAN.
3.1.2 LAN IP ADDRESSES AND SUBNETS
IP addresses on the LAN are controlled either by the CVE-30360’s built-in DHCP
server (see DHCP on page 27), or by you (when you manually assign IP addresses
to your computers).
For more information about IP addresses and subnets in general, see IP Addresses
and Subnets on page 25.
40
HITRON CVE-30360 USER’S GUIDE
LAN
3.1.3 DOMAIN SUFFIX
A domain is a location on a network, for instance example.com. On the Internet,
domain names are mapped to the IP addresses to which they should refer by the
Domain Name System. This allows you to enter “www.example.com” into your
browser and reach the correct place on the Internet even if the IP address of the
website’s server has changed.
Similarly, the CVE-30360 allows you to define a Domain Suffix to the LAN. When
you enter the domain suffix into your browser, you can reach the CVE-30360 no
matter what IP address it has on the LAN.
3.1.4 DEBUGGING (PING AND TRACEROUTE)
The CVE-30360 provides a couple of tools to allow you to perform network
diagnostics on the LAN:
Ping: this tool allows you to enter an IP address and see if a computer (or other
network device) responds with that address on the network. The name comes
from the pulse that submarine SONAR emits when scanning for underwater
objects, since the process is rather similar. You can use this tool to see if an IP
address is in use, or to discover if a device (whose IP address you know) is
working properly.
Traceroute: this tool allows you to see the route taken by data packets to get
from the CVE-30360 to the destination you specify. You can use this tool to
solve routing problems, or identify firewalls that may be blocking your access to
a computer or service.

FIREWALL

FIREWALL
This chapter describes the screens that display when you click Firewall in the
toolbar.
4.1 FIREWALL OVERVIEW
This section describes some of the concepts related to the Firewall screens.
4.1.1 FIREWALL
The term “firewall” comes from a construction technique designed to prevent the
spread of fire from one room to another. Similarly, your CVE-30360’s firewall
prevents intrusion attempts and other undesirable activity originating from the WAN,
keeping the computers on your LAN safe. You can also use filtering techniques to
specify the computers and other devices you want to allow on the LAN, and prevent
certain traffic from going from the LAN to the WAN.
4.1.2 INTRUSION DETECTION SYSTEM
An intrusion detection system monitors network activity, looking for policy violations,
and malicious or suspicious activity.
4.1.3 PING
The CVE-30360 allows you to use the ping utility on the LAN (in the LAN > Debug
screen) and also on the WAN (in the Firewall > Firewall Options screen). For more
information, see Debugging (Ping and Traceroute) on page 40.
4.1.4 MAC FILTERING
Every networking device has a unique Media Access Control (MAC) address that
identifies it on the network. When you enable MAC address filtering on the CVE-
30360’s firewall, you can set up a list of MAC addresses, and then specify whether
you want to:
48
HITRON CVE-30360 USER’S GUIDE
FIREWALL
Deny the devices on the list access to the CVE-30360 and the network (in which
case all other devices can access the network)
or
Allow the devices on the list to access the network (in which case no other
devices can access the network)
4.1.5 IP FILTERING
IP filtering allows you to prevent computers on the LAN from sending certain types of
data to the WAN. You can use this to prevent unwanted outgoing communications.
Specify the IP address of the computer on the LAN from which you want to prevent
communications, and specify the port range of the communications you want to
prevent. The CVE-30360 discards outgoing data packets that match the criteria you
specified.
4.1.6 PORT FORWARDING
Port forwarding allows a computer on your LAN to receive specific communications
from the WAN. Typically, this is used to allow certain applications (such as gaming)
through the firewall, for a specific computer on the LAN. Port forwarding is also
commonly used for running a public HTTP server from a private network.
You can set up a port forwarding rule for each application for which you want to open
ports in the firewall. When the CVE-30360 receives incoming traffic from the WAN
with a destination port that matches a port forwarding rule, it forwards the traffic to the
LAN IP address and port number specified in the port forwarding rule.
NOTE: For information on the ports you need to open for a particular application,
consult that application’s documentation.
NOTE: This feature is not available when the DS-lite function is enabled.
4.1.7 PORT TRIGGERING
Port triggering is a means of automating port forwarding. The CVE-30360 scans
outgoing traffic (from the LAN to the WAN) to see if any of the traffic’s destination
ports match those specified in the port triggering rules you configure. If any of the
ports match, the CVE-30360 automatically opens the incoming ports specified in the
rule, in anticipation of incoming traffic.
NOTE: This feature is not available when the DS-lite function is enabled.
49
HITRON CVE-30360 USER’S GUIDE
FIREWALL
4.1.8 DMZ
In networking, the De-Militarized Zone (DMZ) is a part of your LAN that has been
isolated from the rest of the LAN, and opened up to the WAN. The term comes from
the military designation for a piece of territory, usually located between two opposing
forces, that is isolated from both and occupied by neither.
NOTE: This feature is not available when the DS-lite function is enabled.
4.2 THE FIREWALL OPTIONS SCREEN
Use this screen to turn firewall features on or off, and to configure your network’s
Demilitarized Zone (DMZ). You can enable or disable the CVE-30360’s intrusion
detection system, and allow or prevent responses to ICMP requests from the WAN.

This chapter provides an introduction to wireless networking, describes some
common wireless network setup procedures, and documents the screens that display
when you click Wireless in the toolbar. It contains the following sections:
Wireless Basics on page 69: this section describes how wireless networks work
and are secured.
Wireless Tutorials on page 71: this section describes how to perform some
common wireless network configuration tasks using your CVE-30360.
Advanced Wireless Networking on page 74: this section provides more in-depth
information.
If you are just interested in setting up your wireless network in a standard
configuration you do not need to read this section.
The Wireless Screens on page 76: this section provides detailed information on
each of the CVE-30360’s wireless screens.
Use this section as a reference to find out about a particular screen or field.
6.1 WIRELESS BASICS
This section describes how wireless networks and wireless security work.
Your CVE-30360’s wireless network is part of the Local Area Network (LAN), known
as the Wireless LAN (WLAN). The WLAN is a network of radio links between the
CVE-30360 and the other computers and devices that connect to it.
In the following figure, the wireless network is the part in the circle. The laptop and the
PC are called “wireless clients” and connect to the CVE-30360, which is called the
“access point” or “AP”. The wireless clients can use the AP to access other devices
(such as the printer) or the Internet.
70
HITRON CVE-30360 USER’S GUIDE
WIRELESS
FIGURE 25: Example Wireless Network
6.1.1 WIRELESS STANDARDS
The way in which wireless devices communicate with one another is standardized by
the Institute of Electrical and Electronics Engineers (IEEE). The IEEE standards
pertaining to wireless LANs are identified by their 802.11 designation. There are a
variety of WLAN standards, but the CVE-30360 supports the following (in order of
adoption - old to new - and data transfer speeds - low to high):
IEEE 802.11b
IEEE 802.11g
IEEE 802.11n
6.1.2 SERVICE SETS AND SSIDS
Each wireless network, including all the devices that comprise it, is known as a
“Service Set”.
Each Service Set is identified by a Service Set IDentifier (SSID). This is the name of
the network. Wireless clients must know the SSID in order to be able to connect to
the AP.
You can configure the CVE-30360 to broadcast the SSID (in which case, any client
who scans the airwaves can discover the SSID), or to “hide” the SSID (in which case
it is not broadcast, and only users who already know the SSID can connect). See
Hiding the Network on page 73 for more information.
71
HITRON CVE-30360 USER’S GUIDE
WIRELESS
6.1.3 BASIC WIRELESS SECURITY
Radio is inherently an insecure medium, since it can be intercepted by anybody in the
coverage area with a radio receiver. Therefore, a variety of techniques exist in an
attempt to secure it.
These techniques control authentication (identifying who should be allowed to join the
network) and encryption (signal scrambling so that only authenticated users can
decode the transmitted data). The sophistication of each security method varies, as
does its effectiveness.
The CVE-30360 supports the following wireless security protocols (in order of
effectiveness):
For more information on these security protocols, see Advanced Wireless Security on
page 74.
6.2 WIRELESS TUTORIALS
This section walks you through some of the more common wireless networking tasks.
NOTE: For basic wireless network setup, please see the Quick Installation Guide that
came with your CVE-30360.
These tasks include:
Choosing a Security Method on page 71
Changing the Wireless Password on page 72
Changing the Network Name (SSID) on page 73
Hiding the Network on page 73
Improving the Wireless Network’s Performance on page 73
6.2.1 CHOOSING A SECURITY METHOD
The security method that you choose to use for your wireless network depends upon
the security methods supported by the devices on the network (the CVE-30360, your
PC, your laptop, and so on).
Not all devices support the same security methods, so you must find out what
security methods each of the supports, and choose a method that they all support.
Least secure
No security
WEP
WPA-PSK
Most secure
WPA2-PSK
72
HITRON CVE-30360 USER’S GUIDE
WIRELESS
You should choose the best security method available; see Basic Wireless Security
on page 71 for a list of methods the CVE-30360 supports, in order of effectiveness.
In order to find out which security methods your other wireless devices support, you
can:
Look at the wireless device and see if it has a label listing the methods
supported.
Look at any documentation or packaging that came with the device.
Go into the device’s configuration utility and look for a list of supported methods.
This is often displayed as a drop-down list from which you can select an option.
Go to the device’s manufacturer’s website and look for an information page that
lists the device’s specifications.
If you want to use WPS (see WPS on page 75) all the wireless clients must also
support WPS. There are two ways to determine if this is the case (in addition to those
described above):
Look at the wireless device and see if it has a physical button labeled “WPS” or
something similar, a wireless “wave” icon (something like ), or the “Wi-Fi
Protected Setup” logo. If any of these are the case, the device probably supports
the WPS PBC (“Push-Button Configuration”) method.
Go into the wireless device’s configuration utility and look for a “WPS” or “Wi-Fi
Protected Setup” screen. This screen should let you know whether the device
supports WPS PBC method, the WPS PIN method, or both (some devices have
a PBC button in their configuration utilities, in addition to or instead of a physical
button).
Once you have chosen a security method, you can select it on the CVE-30360 in the
Wireless > Security screen’s Security Mode field (see The Security Screen on
page 78).
6.2.2 CHANGING THE WIRELESS PASSWORD
Only wireless clients with the correct password can access the network. It’s a good
idea to change your wireless network’s password every so often, if you think
someone knows it who shouldn’t, or if there’s suspicious activity on your network.
You should change the password on the CVE-30360, then change the password on
each of your wireless clients.
The procedure for changing the password on the CVE-30360 depends on the
security method your network is using.
If you are using the WPS PBC (“Push-Button Configuration”) security method,
where you press a button on the CVE-30360 and the other wireless devices,
which connect automatically, just run the WPS PBC process again; see the
Quick Installation Guide that came with your CVE-30360 for more information on
how to do this.

If you are using the WPS PIN security, where you have a WPS password that
you enter into each device on the network, go to the Wireless > Basic screen
and click the PIN button. In the screen that displays, enter the WPS PIN that you
want to use for the CVE-30360, or the WPS PIN of the client device you want to
add to the network.
If you are using WEP, go to the Wireless > Security screen. Use the WEP
Settings section to define the key(s) you want to use. Click Apply when you
have finished.
If you are using WPA-PSK or WPA2-PSK, go to the Wireless > Security
screen. In the WPA_Personal section, enter the new password in the Pre-
Shared Key field. Click Apply when you have finished.
Whichever security method you are using, when you change the password on the
CVE-30360, the other devices will not be able to connect to the network until you
change their passwords as well.
The way in which you change the password on the client devices differs according to
manufacturer and model. In general, you will need to log in to the device’s
configuration utility and perform a similar procedure to the one you just performed on
the CVE-30360, unless you are using the WPS PBC method, in which case you must
press the button within two minutes of pressing the button on the CVE-30360.
NOTE: If you are using WPS PBC, bear in mind that any device that also supports
WPS can connect to the CVE-30360 during the connection period. It is
therefore not an ideal method to use in public places, or if you suspect
someone is attempting to gain unauthorized access to the network.
6.2.3 CHANGING THE NETWORK NAME (SSID)
To change your wireless network’s SSID (the name that displays when you scan for
wireless networks on your wireless client), go to the Wireless > Basic screen. Enter
the new network name in the SSID Name field and click Apply.
NOTE: Since the SSID is required to connect to a network, you will need to re-
connect your wireless client devices to the new SSID.
6.2.4 HIDING THE NETWORK
There are various reasons that you might not want your network to be visible to
people scanning for available networks. To do this, go to the Wireless > Basic
screen. Select the Hidden checkbox and click Apply.
6.2.5 IMPROVING THE WIRELESS NETWORK’S
PERFORMANCE
There are two main factors that affect how well your wireless devices can
communicate:
74
HITRON CVE-30360 USER’S GUIDE
WIRELESS
1 Interference from physical objects
2 Radio Frequency (RF) interference
To minimize interference from physical objects:
Move the CVE-30360 away from walls, heavy furniture, other massive or
metallic objects like refrigerators, and so forth.
Install the CVE-30360 in a higher location.
To minimize RF interference:
Move the CVE-30360 away from sources of RF energy such as wireless
telephone base stations, microwaves, and so forth.
Conduct a wireless site audit to see if other wireless networks are interfering with
yours. If so, you can change the wireless channel to one that isn’t so congested.
To conduct a site audit on the CVE-30360, go to the Wireless > WiFi Site
Survey screen. Click Scan. The screen that displays shows the wireless
networks in the area, the Ch field shows the channel they are using, and the
Signal (%) field shows how strongly the CVE-30360 is receiving their signal
(bear in mind that the strength of a network at the CVE-30360’s location is not
necessarily the same as at your wireless client’s location; it may be much
stronger there).
If there are a lot of networks or a very strong network using a single channel or a
group of channels, you can change the CVE-30360’s channel to one further
away from the congested channel. To do this on the CVE-30360, go to the
Wireless > Basic screen and choose an option from the Channel list. You
should choose a channel as far away from the congested area as possible;
ideally a difference of five channels is desirable.
Depending on their configuration, you may also then need to change the channel
on your wireless client devices.
6.3 ADVANCED WIRELESS NETWORKING
This section provides more technical information about wireless networks.
NOTE: If you are just setting up your wireless network in a standard configuration
(covered in Wireless Tutorials on page 71) you do not need to read this
section.
6.3.1 ADVANCED WIRELESS SECURITY
This section describes the CVE-30360’s supported security protocols in greater
detail.
75
HITRON CVE-30360 USER’S GUIDE
WIRELESS
WEP (the Wired Equivalency Protocol): this protocol uses a series of “keys” or
data strings to authenticate the wireless client with the AP, and to encrypt data
sent over the wireless link. WEP is a deprecated protocol, and should only be
used when it is the only security standard supported by the wireless clients.
WEP provides only a nominal level of security, since widely-available software
exists that can break it in a matter of minutes.
WPA-PSK (WiFi Protected Access - Pre-Shared Key): WPA was created to
solve the inadequacies of WEP. There are two types of WPA: the “enterprise”
version (known simply as WPA) requires the use of a central authentication
database server, whereas the “personal” version (supported by the CVE-30360)
allows users to authenticate using a “pre-shared key” or password instead.
While WPA provides good security, it is still vulnerable to “brute force”
password-guessing attempts (in which an attacker simply barrages the AP with
join requests using different passwords), so for optimal security it is advised that
you use a random password of thirteen characters or more, containing no
“dictionary” words.
WPA2-PSK: WPA2 is an improvement on WPA. The primary difference is that
WPA uses the Temporal Key Integrity Protocol (TKIP) encryption standard
(which has been shown to have certain possible weaknesses), whereas WPA2
uses the stronger Advanced Encryption Standard (AES) in the Counter mode
with Cipher block chaining Message authentication code Protocol (CCMP),
which has received the US government’s seal of approval for communications
up to the Top Secret security level. Since WPA2-PSK uses the same pre-shared
key mechanism as WPA-PSK, the same caveat against using insecure or
simple passwords applies.
6.3.2 OTHER WIRELESS CONCEPTS
This section provides information on wireless-related topics not covered in previous
sections.
6.3.2.1 WPS
WiFi-Protected Setup (WPS) is a standardized method of allowing wireless devices
to quickly and easily join wireless networks, while maintaining a good level of
security. The CVE-30360 provides two methods of WPS authentication:
Push-Button Configuration (PBC): when the user presses the PBC button on
the AP (either a physical button, or a virtual button in the GUI), any user of a
wireless client that supports WPS can press the corresponding PBC button on
the client within two minutes to join the network.
Personal Identification Number (PIN) Configuration: all WPS-capable
devices possess a PIN (usually to be found printed on a sticker on the device’s
housing). When you configure another device to use the same PIN, the two
devices authenticate with one another.
Once authenticated, devices that have joined a network via WPS use the WPA2
security standard.
76
HITRON CVE-30360 USER’S GUIDE
WIRELESS
6.3.2.2 WMM
WiFi MultiMedia (WMM) is a Quality of Service (QoS) enhancement that allows
prioritization of certain types of data over the wireless network. WMM provides four
data type classifications (in priority order; highest to lowest):
Voice
Video
Best effort
Background
If you wish to improve the performance of voice and video (at the expense of other,
less time-sensitive applications such as Internet browsing and FTP transfers), you
can enable WMM. You can also edit the WMM QoS parameters, but are disadvised
to do so unless you have an extremely good reason to make the changes.

The CVE-30360 supports up to four WEP keys, of which
you can select one as the default. You should input the
same four keys, in the same order, in your network’s
wireless clients. Your CVE-30360 and your wireless
clients can use different default keys, as long as all four
keys are present and in the same order. If your wireless
client supports only a single WEP key, use the CVE-
30360’s default key.
Enter the keys in hexadecimal format (using the digits
0~9 and the letters A~F).
Default WEP Key Select the number of the security key that you want the
CVE-30360 to use as its default authentication key for
transmissions.
Authentication Select the authentication mode that you want to use:
Select Open System to allow wireless clients to
authenticate (identify themselves) to the CVE-30360
before presenting their security credentials (WEP
keys).
Select Shared Key to use the WEP key in the
authentication process. When a client wants to
associate, the CVE-30360 sends an unencrypted
challenge message. The client must use the WEP
key to encrypt the challenge message and return it to
the CVE-30360, which then decrypts the message
and compares the result with its original message.
Open System authentication is the more secure of the
two authentication types, since while the Shared Key
system appears more robust, it is possible to derive
secure data by capturing the challenge messages.
Select Automatic to have the CVE-30360 choose
the authentication method.

1 Ensure that your wireless client device is functioning properly, and is configured
correctly. See the wireless client’s documentation if unsure.
2 Ensure that the wireless client is within the CVE-30360’s radio coverage area.
Bear in mind that physical obstructions (walls, floors, trees, etc.) and electrical
interference (other radio transmitters, microwave ovens, etc) reduce your CVE-
30360’s signal quality and coverage area.
3 Ensure that the CVE-30360 and the wireless client are set to use the same
wireless mode and SSID (see The Basic Screen on page 76) and security
settings (see The Security Screen on page 78).
4 Re-enter any security credentials (WEP keys, WPA(2)-PSK password, or WPS
PIN).
5 If you are using WPS’s PBC (push-button configuration) feature, ensure that you
are pressing the button on the CVE-30360 and the button on the wireless client
within two minutes of one another.
