Basic Wireless Settings

Open “Basic Settings” in “Wireless” as below to make basic wireless configuration.

Figure 25 Basic Wireless Settings

Disable Wireless LAN Interface

Check this option to disable WLAN interface, then the wireless module of JetWave 2450 will stop
working and no wireless device can connect to it.

Wireless Mode

Four operating modes are available on JetWave 2450.

Wireless Client

: The JetWave 2450 is able to connect to the AP and thus join the wireless

network around it.

AP

: The JetWave 2450 establishes a wireless coverage and receives connectivity from other

wireless devices.

Bridge

: The JetWave 2450 establishes wireless connectivity with other APs by key-in remote

MAC address .If necessary, please refer to the “WDS Setting”.

AP Repeater

: The JetWave 2450 servers as AP and Bridge at the same time. In other words, the

JetWave 2450 can provide connectivity services for CPEs unde r WDS mode.

Chapter 3 Basic Settings Page 25

Wireless Network Name (SSID)

This wireless network name is shared among all associated devices in your wireless network.
Keep it identical on all those devices. Note that the SSID is case-sensitive and can not exceed 32
characters.

Broadcast SSID

Under AP mode, hiding network name is necessary when you are in a wireless environment that
may have potential risk. By disabling broadcast SSID, the STA can not scan and find JetWave
2450, so that malicious attack by some illegal STA could be avoided.

802.11 Mode
The JetWave 2450 can communicate with wireless devices of 802.11b/g or 802.11b/g/n. You can
also select Auto and make it work under an appropriate wireless mode automatically.

HT Protect

Enable HT (High Throughput) protect to ensure HT transmission with MAC mechanism. Under

802.1 1n mode, wirel ess client ca n be divided into HT STA and Non-HT STA, among which the one
with HT protect enabled gets higher throughput.

Channel Number

Channel varies much as the available band differs from country to country. Select a proper
operating channel in the drop-down list according to your situation.

Antenna

By default, JetWave 2450 uses its built-in antenna for directional transmission; however, if you
prefer to use an external antenna for your case-dependent applications, you can switch from
“Internal (8 dBi)” to”External (N-Type)”.

Note:

You a re able to choose “External (N-Type)” only when you have well done installing the

external antenna; otherwise, it might hurt JetWave 2450 itself.

Output Power

Specify the signal transmission power. The higher the output power is, the wider the signal can
cover, but the power consumption will be greater accordingly. Usually “Full” is preferred.

Chapter 3 Basic Settings Page 26

Data Rate

Usually “Auto” is preferred. Under this rate, the JetWave 2450 will automatically select the highest
available rate to transmit. In some cases, however, like where there is no great demand for speed,
you can have a relatively-low transmit rate for compromise of a long distance.

Channel Mode

Two levels are available: 20MHz and 40MHz. The latter one can enhance the data rate more
effectively, but takes more bandwidth, thus cause potential interference.

Extension Channel Protection Mode

This is to avoid conflict with other wireless network and boost the ability of your device to catch all

802.11g transmissions. However, it may decrease wireless network performance. Compared to
CTS-Self; the transmission amount of CTS-RTS is much lower.

Enable MAC Clone

Available only under wireless client mode, it hides the MAC address of the AP while displays the
one of associated wireless client or the MAC address designated manually.

Site Survey

Under wireless client mode, the JetWave 2450 is able to perform site survey, through which,
information on the available access points will be detected.
Open “Basic Settings” in “Wireless”, by clicking the “Site Survey” button beside “Wireless Mode”
option, the wireless site survey window will popup with a list of available wireless networks around.
Select the AP you woul d like to conne ct and clic k “Selected” to establish connection. The wireless site
survey window can also be viewed by opening the “Site Survey” page in “Tools”.

Figure 27 Advanced Wireless Settings

WMM Support

WMM (Wi-Fi Multimedia) is a subset of 802.11e. It allows wireless communication to define a
priority limit on the basis of data type under AP mode only, thus those time-sensitive data, like
video/audio data, may own a higher priority than common one. To enable WMM, the wireless
client should support it.

A-MPDU/A-MSDU Aggregation

The data rate of your AP except wireless client mode could be enhanced greatly with this option
enabled; however, if your wireless clients don’t support A-MPDU/A-MSDU aggregation, it is
recommended not to enable it.

Chapter 4 Advanced Settings Page 28

Short GI

Under 802.1 1 n mode, enable it to obt ain better data rate if there is no negative co mpatibility issue.

RTS Threshold

The JetWave 2450 sends RTS (Request to Send) frames to certain receiving station and
negotiates the sending of a data frame. After receiving an RTS, that STA responds with a CTS
(Clear to Send) frame to acknowledge the right to start transmission. The setting range is 0 to
2346 in byte.

Fragmentation Length

Specify the maximum size in byte for a packet before data is fragmented into multiple packets.
Setting it too low may result in poor network performance. Leave it at its default of 2346 is
recommended.

Beacon Interval

Specify the frequency interval to broadcast packets. Enter a value between 20 and 1024.

DTIM Interval

DTIM, which stands for Delivery Traffic Indication Message, is contained in the data packets. It is
for enhancing the wireless transmission ef ficiency. The default is set to 1. Enter a value between 1
and 255.

Preamble Type

It defines some details on the 802.11 physical layer. “Long” and “Short” are available.

IGMP Snooping

IGMP snooping is the process of listening to IGMP network traffic. By enabling IGMP snooping,
the AP will listen to IGMP membership reports, queries and leave messages to identify the ports
that are members of multicast groups. Multicast traffic will only be forwarded to ports identified as
members of the specific multicast group or groups.

Wireless Separation

Wireless separation is an ideal way to enhance the security of network transmission. Under the
mode except wirless client mode, enable “Wireless Separation” can prevent the communication
among associated wireless clients.

RIFS

RIFS (Reduced Interframe Spacing) is a means of reducing overhead and thereby increasing
network efficiency.

Chapter 4 Advanced Settings Page 29

Link Integration

Available under AP/Bridge/AP repeater mode, it monitors the connection on the Ethernet port by
checking “Enabled”. It can inform the associating wireless clients as soon as the disconnection
occurs.

Max. Station Num

Available only under AP mode, it defines the maximum amount of wireless clients allowed to be
connected.

Space in Meter/ACK Timeout

To decrease the chances of data retransmission at long distance, the JetWave 2450 can
automatically adjust proper ACK timeout value by specifying distance of the two nodes.

Flow Control

It allows the administrator to specify the incoming and outgoing traffic limit by checking “Enable
Traffic Shaping”. This is only available in Router mode.

We strongly recommended you leave most advanced settings at their defaults except

“Distance in Meters” adjusted the parameter for real dist an ce; any modificatio n on them
may negatively impact the performance of your wireless network.

Note:

Chapter 4 Advanced Settings Page 30

Wireless Security Settings

To prevent unauthorized radios from accessing data transmitting over the connectivity, the JetWave
2450 provides you with rock solid security settings.

Security Settings

Open “Security Settings” in “Wireless” as below:

Figure 28 Security Settings

Network Authentication

Open System

: It allows any device to join the network without performing any security check.

Shared Key

: Data encryption and key are required for wireless authentication.

Legacy 802.1x

: As an IEEE standard for port-based Network Access Control, it provides the
rights to access the wireless network and wired Ethernet. With User and PC identity, centralized
authentication as well as dynamic key management, it controls the security risk of wireless
network to the lowest. To serve the 802.1x, at least one EAP type should be supported by the
RADIUS Server, AP and wireless client.

WPA with RADIUS

: With warrant (username, password and etc.) offered by user, this kind of
authentication can be realized with specific RADIUS server. This is the common way to be
adopted in large enterprise network.

WPA2 with RADIUS

: As a new version of WPA, only all the clients support WPA2, can it be

available. If it is selected, AES encryption and RADIUS server is required.

Chapter 4 Advanced Settings Page 31

WP A&WPA2 with RADIUS: It provides options of WPA (TKIP) or WPA2 (AES) for the client. If it is
selected, the data encryption type must be TKIP + AES and the RADIUS server must be set.

WPA-PSK

: It is a simplified WPA mode with no need for specific authentication server. In this
so-called WPA Pre-Sha red Key, all you have to do is just pre-enter a key in each WLAN node and
this is the common way to be adopted in large and middle enterprise as well as residential
network.

WPA2-PSK

: As a new version of WPA, only all the clients support WPA2, can it be availabl e. If it is

selected, the data encryption can only be AES and the passphrase is required.

WPA-PSK&WPA2-PSK

: It provides options of WPA (TKIP) or WPA2 (AES) encryption for the
client. If it is selected, the data encryption can only be TKIP + AES and the passphrase is
required.

Data Encryption

If data encryption is enabled, the key is required and only sharing the same key with other
wireless devices can the communication be established.

None

: Available only when the authentication type is open system.

64 bits WEP

: It is made up of 10 hexadecimal numbers.

128 bits WEP

: It is made up of 26 hexadecimal numbers.

152 bits WEP

: It is made up of 32 hexadecimal numbers.

TKIP

: Temporal Key Integrity Protocol, which is a kind of dynamic encryption, is co-used with

WP A-PSK, etc.

AES

: Advanced Encryption Standard, it is usually co-used with WPA2-PSK, WPA, WPA2, etc.

TKIP + AES

: It allows for backwards compatibility with devices using TKIP.

Note:

We strongly recommend you enable wireless security on your network!
Only setting the same Authentication, Data Encryption and Key in the JetWave 2450

and other associated wireless devices, can the communication be established!

Chapter 4 Advanced Settings Page 32

products, the MAC Address is 001277-XXXXXX. There are two ways available to know it.

• Each device has a label posted with the MAC address. Please refer to below.

Figure 15 MAC Address

• On the JetWave 2450 Web-based management interface, you can view the MAC Address
from “View JetWave 24 50 Basic Information”.

Q 2. Wha t if I would like to reset the unit to default settings?

You may restore factory default settings in “Configuration File” from “Management”.

Q 3. Wha t if I would like to backup and retrieve my configuration settings?

You may do the backup by generating a configuration file or retrieve the settings you have backed
up previously in “Configuration File” from “Management”.

Q 4. Wha t if I can not access the Web-based management interface?

Please check the followings:

• Check whether the power supply is OK; Try to power on the unit again.

• Check whether the IP address of PC is correct (in the same network segment as the unit);

• Login the unit via other browsers such as Firefox.

• Hardware reset the unit.

Chapter 7 Troubleshooting Page 44

Q 5. What if the wireless connection is not stable after associating with an AP under wireless

client mode?

• Since the JetWave 2450 comes with a built-in directional antenna, it is recommended make
the JetWave 2450 face to the direction whe re the AP is to get the best connection quality.

• In addition, you can start “Site Survey” in “Wireless Basic Settings” to check the signal
strength. If it is weak or unstable (The smaller the number is, the weaker the signal strength
is.), please join other available AP for better connection.
