Chapter 1: Introduction

The RG230 WiMAX Residential Gateway is a WiMAX subscriber station designed to
provide Internet access for a home or small office. The unit provides a gateway
function between a WiMAX service provider and a local Ethernet LAN. The device
enables a service provider to deliver last mile broadband wireless access as an
alternative to wired DSL or cable modems.

The RG230 is a plug-and-play indoor unit (IDU). There are two available models for
each of the 2.3, 2.5, and 3.5 GHz WiMAX frequency bands. Which model you use
will depend on the frequency band of your service provider’s WiMAX service. The
RG230 models also include built-in WiMAX antennas, either standard
“omnidirectional” type or high-performance “switched-beam” type.

The RG230 includes four RJ-45 Ethernet switch ports for LAN connections and two
RJ-11 Voice over IP (VoIP) phone ports. An 802.11b/g Wi-Fi module is available for
the 3.5 GHz models that provides a local Wi-Fi access point service.

The following table lists the available RG230 models.

The RG230 offers a user-friendly web-based management interface for the
configuration of all the unit’s features. Any PC directly attached to the unit can
access the management interface using a web browser, such as Internet Explorer
(version 6.0 or above) or Firefox (version 1.5 or above).

The initial configuration steps can be made through the web browser interface using
the Setup Wizard. It is recommended to make the initial changes by connecting a
PC directly to one of the RG230’s LAN ports.

Press the button for less than 3 seconds to start a partial scan to find the best of
known frequency channels. Press and hold down the button for longer than
3 seconds to perform a full frequency scan of all channels.

Reset Button

This button is used to reset the RG230 or restore the factory default configuration. If
you press the button for less than 1 second, the unit will perform a hardware reset. If
you press and hold down the button for 5 seconds or more, any configuration
changes you may have made are removed, and the factory default configuration is
restored to the unit.

WiMAX Antennas

Two internal antennas are built into the RG230 for WiMAX communications. Either
“omnidirectional” or “switched-beam” antennas, depending on the model. The
omnidirectional antennas transmit and receive signals in all directions equally. The
switched-beam antennas detect the direction of the service provider’s base station
and only transmit and receive signals in that direction. Models with the built-in
switched-beam antennas provide better WiMAX performance than those with the
omnidirectional antennas.

WiMAX External Antenna Connectors

Two connectors are available on the top of the unit for attaching optional external
antennas. Depending on a user’s location, the use of an external antenna may
provide a better connection to a WiMAX base station. External antennas also offer
various possible mounting locations.

LAN

The RG230 must have a valid IP address for management using a web browser and
to support other features. The unit has a default IP address of 192.168.1.1. You can
use this IP address or assign another address that is compatible with your existing
local network. The unit can also be enabled as a Dynamic Host Configuration
Protocol (DHCP) server to allocate IP addresses to local PCs.

LAN Settings

The RG230 includes a DHCP server that can assign temporary IP addresses to any
attached host requesting the service. Addresses are assigned to clients from a
common address pool configured on the unit. Configure an address pool by
specifying start and end IP addresses. Be sure not to include the unit's IP address in
the address pool range.

Figure 5-7 LAN Settings

IP Address – The IP address of the unit. Valid IP addresses consist of four decimal
numbers, 0 to 255, separated by periods.The default setting is 192.168.1.1.

Subnet Mask – Indicates the local subnet mask is fixed as 255.255.255.0.

The Gateway acts as DHCP Server – Check this box to enable the DHCP server.

IP Pool Starting/Ending Address – Specifies the start and end IP address of a

range that the DHCP server can allocate to DHCP clients. You can specify a single
address or an address range. Note that the address pool range is always in the
same subnet as the unit’s IP setting. (Default: 192.168.1.2 to 192.168.1.254)

Lease Time – Selects a time limit for the use of an IP address form the IP pool.
When the time limit expires, the client has to request a new IP address.

DHCP Client List

The DHCP Client List page enables you to see the MAC address of devices that are
currently connected to the unit and have been assigned an IP address by the DHCP
server.

Figure 5-8 DHCP Client List

NAT

Network Address Translation (NAT) is a standard method of mapping multiple
"internal" IP addresses to one "external" IP address on devices at the edge of a
network. For the RG230, the internal (local) IP addresses are the IP addresses
assigned to local PCs by the DHCP server, and the external IP address is the IP
address assigned to the WiMAX interface.

Virtual Server

Using the NAT Virtual Server feature, remote users can access different servers on
your local network using your single public IP address.

Remote users accessing services such as web or FTP at your local site thorugh
your public IP address, are redirected (mapped) to other local server IP addresses
and TCP/UDP port numbers. For example, if you set Type/Public Port to TCP/80
(HTTP or web) and the Private IP/Port to 192.168.7.9/80, then all HTTP requests
from outside users forwarded to 192.168.7.9 on port 80. Therefore, by just using
your external IP address provided by your ISP, Internet users can access the
services they need at the local addresses to which you redirect them.

The more common TCP service port numbers include: HTTP: 80, FTP: 21, Telnet:
23, and POP3: 110.

Note: Adding a host to the DMZ may expose your local network to a variety of security

risks, so only use this option as a last resort.

Firewall

The RG230 provides extensive firewall protection by restricting connection
parameters to limit the risk of intrusion and defending against a wide array of
common hacker attacks. You can also block access to the Internet from clients on
the local network based on IP addresses and TCP/UDP port numbers, or specific
MAC addresses.

Chapter 7: VoIP Settings

Voice over Internet Protocol (VoIP) technology is a way of using the Internet to make
phone calls. Phone calls can be tranmitted over the Internet by encoding a voice call
into data packets at one end and then decoding it back into voice calls at the other
end. This encoding and decoding is from a analog signal (your voice) into a digital
signal (data packets) and then back into an analog signal.

The RG230 uses Session Initiation Protocol (SIP) as the control mechanism that
sets up, initiates, and terminates calls between a caller and a called party. The SIP
messaging makes use of “Proxy,” “Redirect,” and “Registration” servers to process
call requests and find the location of called parties across the Internet. When SIP
has set up a call between two parties, the actual voice communication is a direct
peer-to-peer connection using the standard Real-Time Protocol (RTP), which
streams the encoded voice data across the network.

You can make VoIP calls by connecting a regular phone to one of the RG230’s
RJ-11 Phone ports. You can also make VoIP calls from your computer using a VoIP
application with a simple microphone and computer speakers. Using either method,
VoIP provides an experience identical to normal telephoning.

Before using the VoIP Phone ports on the RG230, you must have an account with a
SIP service provider and configure the required parameters through the web
interface. The RG230 allows the two RJ-11 Phone ports to be configured separately
with different settings.

The VoIP configuration pages include the following options.

Enable Proxy Outbound – Enables the use of proxy servers in the local network to
forward SIP requests. (Default: Disabled)

Always Proxy Outbound – Forces all SIP requests to be forwarded through local
proxy servers. (Default: Disabled)

Expire Time – The time the RG230 waits for a response from a proxy server before
a VoIP call fails. (Range: 60-4294967295 seconds; Default: 3600 seconds)

User Name – The SIP account user name.

Auth. User Name – An alphanumeric string that uniquely identifies the user to the

SIP server.

Auth. Password – An alphanumeric string that uniquely identifies the SIP user’s
permission rights.

Display Name – The name that is displayed to the other party during a call.

SIP Register – The IP address of the SIP registrar server. A registrar is a server that
accepts SIP register requests and places the information it receives in those
requests into the location service for the domain it handles.

SIP Register Port Number – The TCP port number used by the VoIP service
provider’s register server. (Range: 1-65535; Default: 5060)

Proxy Address – Address of the VoIP service provider SIP proxy server.

Proxy Port – The TCP port number used by the VoIP service provider’s SIP proxy

server. (Range: 1-65535; Default: 5060)

SIP Setting

From the VoIP SIP Setting page you can configure SIP parameter details.

RTP TX Packet Size – Specifies a maximum amount of time for transmission of a
RTP data packet. (Options: 10, 20, 30 ms; Default: 20 ms)

RTP Port Base/Limit – The Real-time Transport Protocol (RTP) and Real-time
Control Protocol (RTCP) do not use specified port numbers. You can specify a port
range that the RTP and RTCP traffic can use. Enter the port Base and Limit to define
the range. (Range: 1024-65535)

Stun Server – STUN (Simple Traversal of UDP through NAT (Network Address
Translation)) is a protocol that assists devices behind a NAT firewall or router with

packet routing. The problem of NAT firewalls can also be solved using a proxy
server to control SIP traffic. Specify the IP address and TCP port used by the STUN
server. (Default: 0.0.0.0:3478, “0.0.0.0” means not available; Port Range: 0-65535)

DTMF – Enables the sending of dual-tone multi-frequency (touch tone) phone
signals over the VoIP connection. There are several methods to choose from:

• No DTMF: The DTMF signals are not sent over the VoIP connection.

• In-band Mode: The DTMF signals are sent over the RTP voice stream. In the case
when low-bandwidth codecs are used, the DTMF signals may be distorted.

• 2833 Relay: Uses the RFC 2833 method to relay the DTMF signals over the RTP
voice stream without any distortion. (This is the default.)

• Both In-band and 2833: Uses the best method depending on the codecs selected.

Invite Timeout – The time that the unit waits for a response to a SIP Invite message
before a call fails. If network connections are slow and many SIP calls fail, you may
need to increase this timeout value. (Range: 0-56535 seconds; Default: 12 seconds)

T. 3 8 O pt io n – Selects the method to use when sending fax messages over the VoIP
network from a fax machine connected to one of the RJ-11 Phone ports on the
RG230. (Default: Voice and T.38 Fax Relay)

• T.38 Fax Relay: The SIP protocol sets up the VoIP call, then the T.38 Fax Relay
protocol sends the fax data over the network.

• Voice and T.38 Fax Relay: Enables voice calls and faxes to be sent from the
Phone port connection. When a fax tone signal is detected on the port, the T.38
Fax Relay standard is used instead of the voice codec.

• Voice and Fax Pass Through: Enables voice calls and faxes to be sent from the
Phone port connection. For this option, fax signals are sent over the VoIP network
using the voice codec, just as if it were a voice call.

Dial Plan

A dial-plan string can be specified to control phone numbers dialed out through the
RG230. A dial plan describes the number and pattern of digits that a user dials to
reach a particular telephone number. Access codes, area codes, specialized codes,
and combinations of the number of digits dialed can all be part of a dial plan. This
enables a user to predefine dialling sequences that are permitted. It can help
transfer, check, limit phone numbers, and handle prefixes to certain numbers.

The dial-plan string consists of a single digit rule. A typical example of a dial-plan
string is: [0123]xxxxxx.t

Three standard dial plans are defined; Call Transfer Key, New Call Key, and 3-way
Conference. Up to 10 other dial plans can be defined by the user.

Dial Plan

7-5

7

Figure 7-3 Dial Plan Settings

The function of elements allowed in a dial plan are described in the table below:

When a user dials a series of digits, the dial-plan rule is tested for a possible match.
If a match is made, the dialed sequence is transmitted. If no match is made, the
dialed number is blocked and the user will hear an error tone.

A dial-plan string cannot include spaces between elements. Dialed sequences that
are longer than specified in a dial-plan rule are truncated after the number of
specified digits. For example, if the dial-plan rule is “011x” and “0115678” is dialed,
only the digit sequence “0115” is transmitted.

Table 7-1. Dial Plan Elements

Element Example Description

x xxxx Represents a digit of any value ( 0 to 9) that can be dialed on a

phone. This example has a rule with four digits of any number.

. xx. Indicates zero or more occurrences of the previous symbol. The

example acts like a wildcard, meaning any dialed phone number of
two or more digits is allowed.

0-9 01xx Indicates dialed digits that must be matched. This example only

allows four-digit numbers starting “01.”

[ ] [125-8] Limits a dialed digit to specified values or a range of values. The

example specifies that only digits 1, 2, 5, 6, 7, and 8 are permitted.

t xx.t The timeout indicator that can placed after dialed digits or at the end

of the dial-plan string.

Call Feature

The RG230 allows you to configure several call features, such as call waiting and
call-forwarding. Other call features can be implemented by pressing specific phone
buttons or entering dial patterns.

The table below describes the various call features available.

Note: Some call features may be dependent on support at the SIP server. Check with

the SIP service provider.

Table 7-1. VoIP Call Features

Call Feature Description Activation

Call Hold Places an active call on hold for

an unlimited period of time.

Press the “Flash,” “Flash Hook,” or “Hold”
button on the phone.

Call Waiting If during a call there is another

incoming call, an alert tone is
heard.

This feature must first be enabled using the web
interface. You can place the active call on hold
and switch to the incoming call. You can switch
between the two calls by placing the active call
on hold.

Call Switching Calls two numbers, then

switches between them.

Dial the first number, then place it on hold. Dial
the key sequence “**” and wait until you hear
the dial tone, then dial the second number.
Placing the active call on hold switches to the
other call. If the active call is hung up, the phone
rings again to activate the other call.

Call Transfer Transfers any received call to

another number you specify.

First place the received call on hold, then dial
the transfer key sequence “*#”. When you hear
a dial tone, enter the transfer phone number,
then hang up.

Call Forward Forwards an incoming call to

another number.

This feature can be configured using the web
interface. You can specify forwarding numbers
for all calls, when busy, or for no answer.

3-Way Conference Calls two numbers, then allows

all to talk together.

Dial the first number, then place it on hold. Dial
the key sequence “**” and wait until you hear
the dial tone, then dial the second number.
When the second call is active, dial “*3” to
establish the three-way conference.

Codecs

A codec (coder/decoder) is the way a voice analog signal is converted into a digital
bitstream to send over the network, and how it is converted back into an analog
signal at the receiving end. Codecs differ in the type of data compression that is
used to save network bandwidth and in the time delay caused in the signal. This
results in different voice quality experienced by the user.

The voice codecs in common use today have been standardized by the International
Telecommunication Union Telecommunication Standardization Sector (ITU-T) and
are identified by a standard number, such as G.711 or G.726. The same codec must
be supported at each end of a VoIP call to be able to encode and decode the signal.
Since devices in other networks may want to use different codecs, the RG230
provides support for several common standards.

Figure 7-5 Codecs

Codec – Lists the codecs supported by the RG230. You can enable specific codecs
to use, or enable all. Alternatively, you may want to disable certain codecs, such as
high-bandwidth codecs, to preserve network bandwidth.

• PCMA (G711.aLaw): The ITU-T G.711 with A-law standard codec that uses Pulse
Code Modulation (PCM) to produce a 64 Kbps high-quality voice data stream. This
standard is used in Europe and most other countries around the world.

• PCMU (G711.uLaw): The ITU-T G.711 with mu-law standard codec that uses
Pulse Code Modulation (PCM) to produce a 64 Kbps high-quality voice data
stream. This standard is used in North America and Japan.

• G723: The ITU-T G.723 standard codec that uses Adaptive Differential Pulse Code
Modulation (ADPCM) to produce data streams of 24 and 40 Kbps. This standard
has now been superceded by G.726.

• G729ab: The ITU-T G.729ab standard codec that uses Conjugate Structure
Algebraic-Code Excited Linear Prediction (CS-ACELP) with silence suppression to

Call Block Setting

7-9

7

produce a low-bandwidth data stream of 8 Kbps. Note that DTMF and fax tones do
not transport reliably with this codec, it is better to use G.711 for these signals.

• G726-16/24/32/40: The ITU-T G.726 standard codecs that use Adaptive

Differential Pulse Code Modulation (ADPCM) to produce good-quality,
low-bandwidth data streams of either 16, 24, 32, or 40 Kbps.

Priority Codec List – The RG230 automatically negotiates the codec to use for
each called party. You can specify a priority for the codecs that you prefer to use. For
example, you may want to use a low-bandwidth codec such as G729ab instead of a
high-bandwidth G711 codec. Select a codec in the list, then use the UP and DOWN
buttons to set the priority. The RG230 attempts to use the codec highest in the list
before trying the next lower one.

Call Block Setting

The RG230 can block certain incoming and outgoing phone numbers from making
calls through the unit. You can specify up to 15 incoming and 15 outgoing numbers
to block.

Figure 7-6 Call Block Setting

Phone – Selects either VoIP port PHONE1 or PHONE2.

Outgoing – Blocks outgoing calls from the listed numbers. (Valid characters 0-9)

Incoming – Blocks incoming calls from the listed numbers. (Valid characters 0-9)

Phone Setting

The RG230 allows the timings for certain events on the VoIP phone ports to be
precisely configured. For example, you can specify how long a phone will ring and
how long a dial tone is heard on a phone.

The RG230 also enables the line delay to be specified for each phone so that the
caller’s voice echo is cancelled.

Figure 7-7 Phone Setting

Answer Timeout – The time after which a no answer message is sent to the caller.
(Range: 0-65535 seconds; Default: 180 seconds)

Release Timeout – The time after which a call is terminated when a phone is hung
up. (Range: 0-65535 seconds; Default: 4 seconds)

Dial Tone Timeout – The length of time a dial tone is heard on a connected phone.
(Range: 0-65535 seconds; Default: 16 seconds)

Inter Digit Timeout – The maximum time delay allowed between each dialed digit.
When the time is exceeded, a call is made using the dialed digits.
(Range: 0-65535 seconds; Default: 2 seconds)

Attended Transfer Timeout – The time after which a held call that is being
transferred is terminated. (Range: 0-65535 seconds; Default: 32 seconds)

Note: You can hold a call by pressing the “Flash,” “Flash Hook,” or “Hold” button on

the phone

, then dial a transfer number.

Line Echo Cancellation – Sets the delay time for voice echo cancellation. A voice
echo can be created on some two-wire phone loops, which becomes increasingly
louder and annoying when there is a long delay. If voice echo is a problem during a
call, you can adjust this parameter to try and reduce or remove it. (Options: 0, 8, 16,
24, 32, 36 milliseconds; Default: 0 milliseconds)

Chapter 8: Wi-Fi Settings

The RG230 model for the 3.5 GHz WiMAX band includes an IEEE 802.11g radio
interface for local Wi-Fi communications. The Wi-Fi set up pages include
configuration options for the radio signal characteristics and Wi-Fi security.

The Wi-Fi configuration pages include the following options.

Wireless Settings

From the Wireless menu, click on Settings to configure the unit’s Wi-Fi radio
interface. The unit’s radio can operate in three modes, IEEE, 802.11b & g, 802.11g
only, and 802.11b only.

The IEEE 802.11g standard operates within the 2.4 GHz band at up to 54 Mbps.
Note that because the IEEE 802.11g standard is an extension of the IEEE 802.11b
standard, it allows clients with 802.11b wireless network cards to associate to an

802.11g access point.

Interface Status – Enables the Wi-Fi radio.

Network Name (SSID) – The Service Set ID (SSID) that identifies the Wi-Fi

network. The SSID is case sensitive and can consist of up to 32 alphanumeric
characters. (Default: default)

Radio Channel – The radio channel used by the unit and its clients to communicate
with each other. This channel must be the same on the unit and all of its wireless
clients. The available channel settings are limited by local regulations. (Default: 1;
Range: 1-11)

Note: If you experience poor performance, you may be encountering interference from

another wireless device. Try changing the channel, as this may eliminate
interference and increase performance. Channels 1, 6, and 11, as the three
non-overlapping channels in the 2.4 GHz band, are preferred.

Auto Channel Select – Enables the unit to automatically select an available radio
channel. (Default: Enabled)

Wireless Settings

8-3

8

Working Mode – Selects the operating mode for the 802.11g radio.
(Default: B/G Mixed Mode)

• B/G Mixed Mode: Both 802.11b and 802.11g clients can communicate with the

unit (up to 54 Mbps).

• G Only Mode: Only 802.11g clients can communicate with the unit (up to

54 Mbps).

• B Only Mode: Both 802.11b and 802.11g clients can communicate with the unit,

but 802.11g clients can only transfer data at 802.11b standard rates (up to
11 Mbps).

Transmit Power – Adjusts the power of the radio signals transmitted from the unit.
The higher the transmission power, the farther the transmission range. Power
selection is not just a trade off between coverage area and maximum supported
clients. You also have to ensure that high-power signals do not interfere with the
operation of other radio devices in the service area. (Options: Auto, Full, Min;
Default: Auto)

Tx Data Rate – The maximum data rate at which the unit transmits unicast packets
on the Wi-Fi interface. The maximum transmission distance is affected by the data
rate. The lower the data rate, the longer the transmission distance. (Default: Auto)

Beacon Interval (1~65535) – Sets the interval at which beacon frames are
transmitted from the unit. The Beacon Interval unit is measured in microseconds.
The beacon signals enable wireless clients to maintain contact with the unit. They
also carry power-management information. (Range: 1-65535 microseconds;
Default: 100 microseconds)

DTIM Interval (1~255) – The Delivery Traffic Indication Map (DTIM) interval. The
rate at which client stations in sleep mode must wake up to receive broadcast/
multicast transmissions. The DTIM interval indicates how often the MAC layer
forwards broadcast/multicast traffic, for which it is necessary to wake up stations that
are using power-save mode. The default value of 3 beacons indicates that the unit
will save all broadcast/multicast frames and forward them after every third beacon.
Using small DTIM intervals delivers broadcast/multicast frames in a more timely
manner, but causes stations in power-save mode to wake up more often and drain
power faster. Using larger DTIM values reduces the power used by stations in
power-save mode, but delays the transmission of broadcast/multicast frames.
(Range: 1-255 beacons; Default: 3 beacons)

Fragment Length (256~2346) – Configures the minimum packet size that can be
fragmented when passing through the unit. Fragmentation of PDUs (Package Data
Units) can increase the reliability of transmissions because it increases the
probability of a successful transmission due to a smaller frame size. If there is
significant interference present, or collisions due to high network utilization, try
setting the fragment size to send smaller fragments. This will speed up the
retransmission of smaller frames. However, it is more efficient to set the fragment

Wi-Fi Settings

8-4

8

size larger if very little or no interference is present because it requires overhead to
send multiple frames. (Range: 256-2346 bytes; Default: 2346 bytes)

RTS Threshold (256~2432) – Sets the packet size threshold at which a Request to
Send (RTS) signal must be sent to a receiving station prior to the sending the data
frame. The unit sends RTS frames to a receiving station to negotiate the sending of
a data frame. After receiving an RTS frame, the station sends a CTS (clear to send)
frame to notify the unit that it can start sending data. If a packet size equals or
exceeds the RTS threshold, the RTS/CTS (Request to Send / Clear to Send)
mechanism will be enabled. Units contending for the medium may not be aware of
each other, and the RTS/CTS mechanism can solve this “Hidden Node Problem.”
(Range: 256-2432 bytes: Default: 2432 bytes)

Preamble Length – All IEEE 802.11 frames begin with an alternating pattern of 1s
and 0s called the preamble, which tells receiving stations that a frame is arriving.
This provides time for the receiving station to synchronize to the incoming data
stream. This parameter sets the length of the signal preamble that is used at the
start of a data transmission. Using a short preamble (96 microseconds) instead of a
long preamble (192 microseconds) can increase data throughput on the unit, but
requires that all clients can support a short preamble. (Default: Short)

• Short: Sets the preamble to short for increased throughput.

• Long: Sets the preamble to long. Using a long preamble ensures the unit can
support all 802.11b and 802.11g clients.

SSID Suppress – When enabled, the RG230 stops broadcasting the configured
SSID in its beacon signal. The unit is configured by default as an “open system,”
which broadcasts a beacon signal including the configured SSID. Wireless clients
with a configured SSID of “ANY” can read the SSID from the beacon, and
automatically set their SSID for immediate connection to the RG230. When enabled,
the unit does not include its SSID in beacon messages. This provides a basic level
of security, since wireless clients must be configured with the SSID to connect to the
RG230.

Frame Burst – Enables data transmission bursting to boost throughput. (Default:
Disabled)

CTS Protection Mode – When 802.11g and 802.11b clients operate together in the
same Wi-Fi network, there needs to be a mechanism that prevents 802.11b clients
interferring with 802.11g transmissions. This is achieved by sending

802.11b-compatible CTS (Clear to Send) or RTS/CTS (Request to Send / Clear to

Send) frames before each transmission. This mechanism decreases the
performance of 802.11g clients, but ensures that 802.11b clients can communicate
with the RG230. (Default:CTS Only)

• Disable: If there are no 802.11b clients in the network, the protection mode can be
disabled.

Wireless Security

8-5

• CTS Only: The transmitting client sends only a CTS frame to prevent others from

accessing the medium. This mechanism is effective for most neworks with mixed

802.11g and 802.11b clients.

• RTS/CTS: Both RTS and CTS frames must be exchanged before a client can send

data. There may be 802.11b clients in some networks that do not detect the CTS
frames from other stations. The full RTS/CTS exchange should solve most
connection problems, but it also has the greatest impact on network performance.

Factory Default – Click the Reset button to set all the Wi-Fi settings to their factory
default values.

Wireless Security

The RG230’s Wi-Fi interface is configured by default as an “open system,” which
broadcasts a beacon signal including the configured SSID. Wireless clients with a
configured SSID of “ANY” can read the SSID from the beacon, and automatically set
their SSID to allow immediate connection to the wireless network.

To implement wireless network security, you have to employ two main functions:

• Authentication – It must be verified that clients attempting to connect to the network

are authorized users.

• Traffic Encryption – Data passing between the unit and clients must be protected

from interception and evesdropping.

For a more secure network, the RG230 can implement one of several security
mechanisms. The security mechanism employed depends on the level of security
required, the network and management resources available, and the software
support provided on wireless clients.

To configure wireless security click on Security.

Figure 8-2. Wireless Security

Wi-Fi Settings

There are eight security options available. When you select the security type in the
table, the required settings are displayed. The option “Open System” together with
encryption disabled is equivalent to no security, all clients will be able to immediately
connect to the Wi-Fi network.

The following sections describe the security options available for the RG230 Wi-Fi
network.

WEP Shared Key Security

Wired Equivalent Privacy (WEP) provides a basic level of security, preventing
unauthorized access to the network and encrypting data transmitted between
wireless clients and the RG230. WEP uses static shared keys (fixed-length
hexadecimal or alphanumeric strings) that are manually distributed to all clients that
want to use the network.

When enabled, you must configure at least one WEP key for the Wi-Fi interface and
all its clients.

Figure 8-3. WEP Shared Key Security

Key 1 ~ Key 4 – Sets WEP key values. The user must first choose between ASCII

or Hexadecimal keys. At least one key must be specified. Each WEP key has an
index number. The selected key is used for authentication and encryption on the
Wi-Fi interface. Enter key values that match the key type and length settings.
(Default: Hex, 64 bits, no preset value)

• Key Type: Specifies keys as either ASCII or Hexadecimal values.

• Key Length: WEP keys can be set as 64, 128, or 152 bits in length.

• Key: Specify keys as either 5, 13, or 16 alphanumeric characters, or 10, 26, or 32
hexadecimal digits, depending on the selected key length.

Default Key Setting – Sets the WEP key used for authentication and encryption.
(Range: 1-4; Default: 1)

Wireless Security

WPA/WPA2 Security

The WPA and WPA2 modes use IEEE 802.1X as their basic framework for user
authentication and dynamic key management. IEEE 802.1X access security uses
Extensible Authentication Protocol (EAP) and requires a configured Remote
Authentication Dial-in User Service (RADIUS) authentication server to be accessible
in the enterprise network. If you select WPA or WPA2 mode, be sure to configure the
RADIUS settings displayed on the page.

The WPA-WPA2-Mixed mode is a transitional mode of operation for networks
moving from WPA security to WPA2. WPA-WPA2-Mixed mode allows both WPA and
WPA2 clients to associate to a common Wi-Fi interface.

Figure 8-4. WPA/WPA2 Security

RADIUS Setting – Configures RADIUS server settings for WPA, WPA2, or

WPA-WPA2-Mixed security modes.

• IP Address/Server Name – Specifies the IP address or domain name of the

RADIUS server.

• Port Number – The User Datagram Protocol (UDP) port number used by the

RADIUS server for authentication messages. (Range: 1024-65535; Default: 1812)

• Secret – A shared text string used to encrypt messages between the unit and the

RADIUS server. Be sure that the same text string is specified on the RADIUS
server. Do not use blank spaces in the string. (Maximum length: 20 characters)

Wi-Fi Settings

Note: This guide assumes that you have already configured a RADIUS server in the

attached wired network to support the unit. Configuration of RADIUS server
software is beyond the scope of this guide, refer to documentation provided with
the RADIUS server software.

WPA/WPA2 PSK Security

The WPA-PSK, WPA2-PSK, and WPA-WPA2-Mixed-PSK modes use a common
password phrase, called a Pre-Shared Key (PSK), that must be manually distributed
to all clients that want to connect to the network. The Pre-shared Key modes of
WPA/WPA2 remove the need for RADIUS server support in the attached network.

You can specify a key as an easy-to-remember form of letters and numbers. The
WPA Pre-shared Key can be input as ASCII string (8-63 characters) or Hexadecimal
format (length is 64). All wireless clients must be configured with the same key to
communicate with the VAP interface.

The WPA-WPA2-Mixed-PSK mode is a transitional mode of operation for networks
moving from WPA security to WPA2. WPA-WPA2-Mixed-PSK mode allows both
WPA and WPA2 clients to associate to a common Wi-Fi interface.

Figure 8-5. WPA/WPA2 PSK Security

WPA Pre-Shared Key – The key required for WPA-PSK, WPA2-PSK, and

WPA-WPA2-Mixed-PSK modes. There are.two methods for key entry: An ASCII
string of 8~63 characters in length (0~9, A~F, including spaces), or 64 hexadecimal
digits.

MAC Authentication

8-9

8

MAC Authentication

Wireless clients can be authenticated for network access by checking their MAC
address against a local database configured on the RG230. You can configure a list
of up to 32 wireless client MAC addresses in the filter list to either allow or deny
network access.

Figure 8-6. MAC Authentication

System Default – Specifies the action for MAC addresses listed in the local MAC

Authentication Table.

• Deny: Blocks access for all MAC addresses listed in the MAC Authentication

Table. Clients with MAC addresses not listed in the table are permitted access.

• Allow: Permits access for all MAC addresses listed in the MAC Authentication

Table. Clients with MAC addresses not listed in the table are denied access.

Local MAC Filter Settings – Adds new MAC addresses to the MAC Authentication
Table, or removes addresses currently listed in the table.

• MAC Address: Physical address of a client. Enter six pairs of hexadecimal digits

separated by colons; for example, 00:90:D1:12:AB:89.

• Permission: Select Add to list a new specified MAC address in the MAC

Authentication Table. Select Delete to remove the specified MAC address from the
table.

• Update: Performs the Add or Delete action on the specified MAC address.

Cannot Access Web Management

If the management interface cannot be accessed using a web browser:

• Be sure the management station is correctly configured for TCP/IP. The IP settings
should be set to “obtain an IP address automatically.”

• Try a Ping command from the management station to the unit’s IP address to verify
that the entire network path between the two devices is functioning correctly.

• Check that the management station has a valid network connection and that the
Ethernet port that you are using has not been disabled.

• Check the network cabling between the management station and the unit. If the
problem is not resolved, try using a different port or a different cable.

Forgot or Lost the Password

Set the unit to its default configuration by pressing the reset button on the back
panel for 5 seconds or more. Then use the default password “admin” to access the
management interface.

Resetting the Unit

If all other recovery measures fail and the unit is still not functioning properly, take
either of these steps:

• Reset the unit using the web interface, or through a power reset.

• Reset the unit to its factory default configuration by pressing the reset button on the
back panel for 5 seconds or more. Then use the default password “admin” to
access the management interface.

Appendix C: Cables and Pinouts

Twisted-Pair Cable Assignments

For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires.
Each wire pair is identified by two different colors. For example, one wire might be
green and the other, green with white stripes. Also, an RJ-45 connector must be
attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific

orientation. (See “Straight-Through Wiring” on page C-2 and “Crossover
Wiring” on page C-2 for an explanation.)

Caution: DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair

cables with RJ-45 connectors that conform with FCC standards.

The following figure illustrates how the pins on the RJ-45 connector are numbered.
Be sure to hold the connectors in the same orientation when attaching the wires to
the pins.

Figure C-1 RJ-45 Connector

10/100BASE-TX Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or
100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure

that the

length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 ports on the unit supports automatic MDI/MDI-X operation, so you can
use straight-through or crossover cables for all network connections to PCs,
switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the
cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the
cable.

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal
crossover (MDI-X), the two pairs of wires must be straight-through.

Figure C-2 Straight-Through Wiring

Crossover Wiring

If the twisted-pair cable is to join two ports and either both ports are labeled with an
“X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be
implemented in the wiring.

RJ-11 Ports

Standard telephone RJ-11 connectors and cabling can be found in several common
wiring patterns. These six-pin connectors can accommodate up to three wire pairs
(three telephone lines), but usually only one or two pairs of conductor pins and wires
are implemented.

The RJ-11 ports on this device contain only one wire pair on the inner pins (3 and 4).
