BASIC WIRELESS SETTINGS

From the WiFi menu, click on Basic to configure basic settings for the unit’s

Wi-Fi radio interface. The unit’s radio can operate in six modes,

IEEE 802.11b/g mixed, 802.11b only, 802.11g only, 802.11n only,

802.11g/n mixed, and 802.11b/g/n mixed.

Note that IEEE 802.11g is backward compatible with 802.11b, and 802.11n

is backward compatible with 802.11b/g at slower data transmit rates.

Figure 1: Wireless Settings

The following items are displayed on this page:

◆Radio Enable — Enables or Disable the radio. (Default: Enable)

◆Network Mode — Defines the radio operating mode. (Default: 11g/n

Mixed)

■11b/g mixed: Both 802.11b and 802.11g clients can communicate

with the Wi-Fi radio (up to 108 Mbps), but data transmission rates

may be slowed to compensate for 802.11b clients. Any 802.11n

clients will also be able to communicate with the Wi-Fi radio, but

they will be limited to 802.11g protocols and data transmission

rates.

■11b only: All 802.11b, 802.11g, and 802.11n clients will be able to

communicate with the Wi-Fi radio, but the 802.11g and 802.11n

clients will be limited to 802.11b protocols and data transmission

rates (up to 11 Mbps).

■11g only: Both 802.11g and 802.11n clients will be able to

communicate with the Wi-Fi radio, but the 802.11n clients will be

limited to 802.11g protocols and data transmission rates (up to 54

Mbps). Any 802.11b clients will not be able to communicate with

the Wi-Fi radio.

■11n only: Only 802.11n clients will be able to communicate with

the Wi-Fi radio (up to 150 Mbps).

■11g/n mixed: Both 802.11g and 802.11n clients can communicate

with the Wi-Fi radio (up to 150 Mbps), but data transmission rates

may be slowed to compensate for 802.11g clients.

■11b/g/n Mixed: All 802.11b/g/n clients can communicate with the

Wi-Fi radio (up to 150 Mbps), but data transmission rates may be

slowed to compensate for 802.11b/g clients.

◆SSID — The name of the wireless network service provided by the Wi-

Fi radio. Clients that want to connect to the network must set their

SSID to the same as that of the Wi-Fi radio. (Default: “SMC”; Range: 1-

32 characters)

◆Hidden — By default, the Wi-Fi radio always broadcasts the SSID in its

beacon signal. Disabling the SSID broadcast increases security of the

network because wireless clients need to already know the SSID before

attempting to connect. (Default: Enabled)

◆Country Code — The country code restricts operation of the Wi-Fi

radio to the channels and transmit power levels permitted for Wi-Fi

networks in the specified region. You must set the correct Country Code

to be sure the radio conforms to local regulations. (Options: United

States, Japan, France, Taiwan, Ireland; Default: Taiwan)

OTE

The Country Code setting is for non-US models only. The US model

does not include this setting.

AUTION

You must set the country code to the country of operation.

Setting the country code restricts operation of the access point to the radio

channels and transmit power levels permitted for wireless networks in the

specified country.

◆Channel — The radio channel that the Wi-Fi radio uses to communicate

with wireless clients. When multiple access points are deployed in the

same area, set the channel on neighboring access points at least five

channels apart to avoid interference with each other. For example, you

can deploy up to three access points in the same area using channels 1,

6, 11. Note that wireless clients automatically set the channel to the

same as that used by the Wi-Fi radio to which it is linked. Selecting

Auto Select enables the Wi-Fi radio to automatically select an

unoccupied radio channel. (Default: Auto)

OTE

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.

◆Channel Width — The Wi-Fi radio provides a channel bandwidth of 40

MHz by default giving an 802.11g connection speed of 108 Mbps

(sometimes referred to as Turbo Mode) and a 802.11n connection

speed of up to 150 Mbps. Setting the Channel Width to 20 MHz slows

connection speed for 802.11g and 802.11n to 54 Mbps and 74 Mbps

respectively and ensures backward compliance for slower 802.11b

devices. (Default: 20MHz)

ADVANCED WIRELESS SETTINGS

The Advanced Settings page includes additional parameters concerning the

wireless network and Wi-Fi Multimedia settings.

Figure 2: Advanced Wireless Settings

The following items are displayed on this page:

◆BG Protection Mode — Enables a backward compatible protection

mechanism for 802.11b clients. There are three modes: (Default: Auto)

■Auto — The unit enables its protection mechanism for 802.11b

clients when they are detected in the network. When 802.11b

clients are not detected, the protection mechanism is disabled.

■On — Forces the unit to always use protection for 802.11b clients,

whether they are detected in the network or not. Note that enabling

b/g Protection can slow throughput for 802.11g/n clients by as

much as 50%.

■Off — Forces the unit to never use protection for 802.11b clients.

This prevents 802.11b clients from connecting to the network.

◆Beacon Period — The rate at which beacon signals are transmitted

from the access point. The beacon signals allow wireless clients to

maintain contact with the access point. They may also carry power-

management information. (Range: 20-999 TUs; Default: 100 TUs)

◆DTIM Period — The rate at which stations in sleep mode must wake

up to receive broadcast/multicast transmissions.

Known also as the Delivery Traffic Indication Map (DTIM) interval, it

indicates how often the MAC layer forwards broadcast/multicast traffic,

which is necessary to wake up stations that are using Power Save

mode. The default value of one beacon indicates that the access point

will save all broadcast/multicast frames for the Basic Service Set (BSS)

and forward them after every beacon. Using smaller DTIM intervals

HAPTER

| Wi-Fi Settings

Advanced Wireless Settings

– 11 –

delivers broadcast/multicast frames in a more timely manner, causing

stations in Power Save mode to wake up more often and drain power

faster. Using higher 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: 1 beacon)

◆Frag Threshold – Configures the minimum packet size that can be

fragmented when passing through the access point. Fragmentation of

the PDUs (Package Data Unit) can increase the reliability of

transmissions because it increases the probability of a successful

transmission due to 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 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 — Sets the packet size threshold at which a Request to

Send (RTS) signal must be sent to a receiving station prior to the

sending station starting communications. The access point 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 sending station that it can start sending data.

If the RTS threshold is set to 0, the access point always sends RTS

signals. If set to 2347, the access point never sends RTS signals. If set

to any other value, and the packet size equals or exceeds the RTS

threshold, the RTS/CTS (Request to Send / Clear to Send) mechanism

will be enabled.

The access points contending for the medium may not be aware of each

other. The RTS/CTS mechanism can solve this “Hidden Node Problem.”

(Range: 1-2347 bytes: Default: 2347 bytes)

◆TX 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. (Range: 1 - 100; Default: 100)

◆Short Slot — Sets the basic unit of time the access point uses for

calculating waiting times before data is transmitted. A short slot time

(9 microseconds) can increase data throughput on the access point, but

requires that all clients can support a short slot time (that is, 802.11g-

compliant clients must support a short slot time). A long slot time

(20 microseconds) is required if the access point has to support

802.11b clients. (Default: Enabled)

◆TX Burst — A performance enhancement that transmits a number of

data packets at the same time when the feature is supported by

compatible clients. (Default: Enabled)

◆Pkt Aggregate — A performance enhancement that combines data

packets together when the feature is supported by compatible clients.

(Default: Enabled)

WIRELESS SECURITY

The RG231’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.

The RG231’s Wi-Fi interface supports supports ten different security

mechanisms that provide various levels of authentication and encryption

depending on the requirements of the network.

Click on “Wi-Fi,” followed by “Security”.

The supported security mechanisms and their configuration parameters are

described in the following sections:

◆OPEN, SHARED, WEP-AUTO — See “Wired Equivalent Privacy (WEP)”

WIRED EQUIVALENT

PRIVACY (WEP)

WEP provides a basic level of security, preventing unauthorized access to

the network, and encrypting data transmitted between wireless clients and

an access point. 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 you select to use WEP, be sure to define at least one static WEP key

for user authentication or data encryption. Also, be sure that the WEP

shared keys are the same for each client in the wireless network.

Figure 4: Security Mode - WEP

The following items are displayed in this section on this page:

◆Auth Mode — Configures the WEP security mode used by clients.

When using WEP, be sure to define at least one static WEP key for the

RG231 and all its clients. (Default: Disable)

◆OPEN — Open-system authentication accepts any client attempting to

connect the RG231 without verifying its identity. In this mode the

default data encryption type is “WEP.”

◆SHARED — The shared-key security uses a WEP key to authenticate

clients connecting to the network and for data encryption.

◆WEP-AUTO — Allows wireless clients to connect to the network using

Open-WEP (uses WEP for encryption only) or Shared-WEP (uses WEP

for authentication and encryption).

◆Encrypt Type — Selects WEP for data encryption (OPEN mode only).

◆Default Key — Selects the WEP key number to use for authentication

or data encryption. If wireless clients have all four WEP keys configured

to the same values, you can change the encryption key to any of the

settings without having to update the client keys. (Default: 1;

Range: 1~4)

◆WEP Keys 1 ~ 4 — Sets WEP key values. The user must first select

ASCII or hexadecimal keys. Each WEP key has an index number. Enter

key values that match the key type and length settings. Enter 5

alphanumeric characters or 10 hexadecimal digits for 64-bit keys, or

HAPTER

Wireless Security

– 14 –

enter 13 alphanumeric characters or 26 hexadecimal digits for 128-bit

keys. (Default: Hex, no preset value)

WPA PRE-SHARED

KEY

Wi-Fi Protected Access (WPA) was introduced as an interim solution for the

vulnerability of WEP pending the adoption of a more robust wireless

security standard. WPA2 includes the complete wireless security standard,

but also offers backward compatibility with WPA. Both WPA and WPA2

provide an “enterprise” and “personal” mode of operation.

For small home or office networks, WPA and WPA2 provide a simple

“personal” operating mode that uses just a pre-shared key for network

access. The WPA Pre-Shared Key (WPA-PSK) mode uses a common

password phrase for user authentication that is manually entered on the

access point and all wireless clients. Data encryption keys are

automatically generated by the access point and distributed to all clients

connected to the network.

Figure 5: Security Mode - WPA-PSK

The following items are displayed in this section on this page:

◆Auth Mode — Configures the WPA-PSK and WPA2-PSK security modes

used by clients. When using WPA-PSK or WPA2-PSK, be sure to define

the shared key for the RG231 and all its clients. (Default: Disable)

◆WPA-PSK — Clients using WPA with a Pre-shared Key are accepted for

authentication. The default data encryption type for WPA is TKIP.

◆WPA2-PSK — Clients using WPA2 with a Pre-shared Key are accepted

for authentication. The default data encryption type for WPA is AES.

◆WPA-PSK_WPA2-PSK — Clients using WPA or WPA2 with a Pre-

shared Key are accepted for authentication. The default data encryption

type is TKIP/AES.

◆EncryptType — Selects the data encryption type to use. (Default is

determined by the Security Mode selected.)

■TKIP — Uses Temporal Key Integrity Protocol (TKIP) keys for

encryption. WPA specifies TKIP as the data encryption method to

replace WEP. TKIP avoids the problems of WEP static keys by

dynamically changing data encryption keys.

■AES — Uses Advanced Encryption Standard (AES) keys for

encryption. WPA2 uses AES Counter-Mode encryption with Cipher

Block Chaining Message Authentication Code (CBC-MAC) for

HAPTER

| Wi-Fi Settings

Wireless Security

– 15 –

message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-

CCMP) provides extremely robust data confidentiality using a 128-

bit key. Use of AES-CCMP encryption is specified as a standard

requirement for WPA2. Before implementing WPA2 in the network,

be sure client devices are upgraded to WPA2-compliant hardware.

■TKIP/AES — Uses either TKIP or AES keys for encryption. WPA and

WPA2 mixed modes allow both WPA and WPA2 clients to associate

to a common SSID. In mixed mode, the unicast encryption type

(TKIP or AES) is negotiated for each client.

◆Pass Phrase — The WPA Preshared Key can be input as an ASCII

string (an easy-to-remember form of letters and numbers that can

include spaces) or Hexadecimal format. (Range: 8~63 ASCII

characters, or exactly 64 Hexadecimal digits)

WPA ENTERPRISE

MODE

Wi-Fi Protected Access (WPA) was introduced as an interim solution for the

vulnerability of WEP pending the adoption of a more robust wireless

security standard. WPA2 includes the complete wireless security standard,

but also offers backward compatibility with WPA. Both WPA and WPA2

provide an “enterprise” and “personal” mode of operation.

For enterprise deployment, WPA and WPA2 use IEEE 802.1X for user

authentication and require a RADIUS authentication server to be

configured on the wired network. Data encryption keys are automatically

generated and distributed to all clients connected to the network.

Figure 6: Security Mode - WPA

The following items are displayed in this section on this page:

◆Auth Mode — Configures the WPA and WPA2 security modes used by

clients. When using WPA or WPA2, be sure there is a RADIUS server in

the connected wired network, and that the RADIUS settings are

configured. See “IEEE 802.1X and RADIUS” on page 16 for more

information. (Default: Disable)

◆WPA — Clients using WPA with an 802.1X authentication method are

accepted for authentication. The default data encryption type for WPA

is TKIP.

◆WPA2 — Clients using WPA2 with an 802.1X authentication method

are accepted for authentication. The default data encryption type for
