NETCOMM LIBERTY™ SERIES

- HSPA+ 42Mbps WiFi Router

7.2 Security

This router includes a number of options to help provide a secure connection to the Wi-Fi Network.

Security features include:

•

WEP / WPA / WPA2 data encryption

•

MAC address IP filtering

You can authenticate or encrypt your service on the Wi-Fi Protected Access algorithm, which provides protection against unauthorized access

such as eavesdropping.

The following screen appears when Security is selected. The Security page allows you to configure security features of your router’s WLAN

interface. You can set the network authentication method, select data encryption, specify whether a network key is required to authenticate to

this wireless network and specify the encryption strength.

Click Apply/Save to configure the wireless security options.

Option

Description

Select SSID

The BB@work is able to handle multiple wireless networks. The pull down menu enables

you to select which wireless network the security settings will be applied to.

Network Authentication

This option is used for authentication to the wireless network. Each authentication type

has its own settings. For example, selecting 802.1X authentication will reveal the RADIUS

Server IP address, Port and key fields.

WEP Encryption

This option indicates whether data sent over the network is encrypted. The same network

key is used for data encryption and network authentication. Whilst four network keys can

be defined, only one can be used at any one time.

WPA-PSK / WPA2-PSK

A new type of wireless security that gives a more secure network when compared to WEP.

The security key needs to be more than 8 characters and less than 63 characters and it

can be any combination of letters and numbers. This is the default wireless security in use

on the router. Default value is listed on your security card

WPA

WPA (Wi-Fi Protected Access) is suitable for enterprise applications. It must be used in

conjunction with an authentication server such as RADIUS to provide centralized access

control and management.

Encryption Strength

The strength/length of your wireless security key.

Current Network Key

The current network key that is active. You have the choice of setting up to 4 different

wireless security keys

Network Key 1

The value of network key 1.

Network Key 2

The value of network key 2

Network Key 3

The value of network key 3

Network key 4

The value of network key 4

NETCOMM LIBERTY™ SERIES

- HSPA+ 42Mbps WiFi Router

Option

Description

Band

The frequency of the wireless network. 2.4GHz is standard.

Channel

Allows selection of a specific channel (1-14) or Auto mode.

Auto Channel Timer

The Auto Channel times the length it takes to scan in minutes.

802.11n/EWC

An equipment interoperability standard setting based on IEEE 802.11n Draft 2.0 and Enhanced

Wireless Consortium (EWC)

Bandwidth

The drop-down menu specifies the following bandwidth: 20MHz in 2.4G Band and 40 MHz in 5G

Band, 20MHz in both bands and 40MHz in both bands

Control Sideband

This is available for 40MHz. Drop-down menu allows selecting upper sideband or lower sideband

802.11n Rate

Drop-down menu specifies the following fixed rates. The maximum rate for bandwidth, 20MHz, is

130Mbps and the maximum bandwidth, 40MHz, is 270Mbps

802.11n Protection

Turn off for maximized throughput Turn on for greater security

Support 802.11n Client Only

The option to provide wireless Internet access only to clients who are operating at 802.11n speeds

54g Rate

In Auto (default) mode, your Router uses the maximum data rate and lowers the data rate

dependent on the signal strength. The appropriate setting is dependent on signal strength. Other

rates are discrete values between 1 to 54 Mbps.

Multicast rate

Setting for multicast packet transmission rate. (1-54 Mbps)

Basic Rate

Sets basic transmission rate.

Fragment Threshold

A threshold (in bytes) determines whether packets will be fragmented and at what size. Packets

that exceed the fragmentation threshold of an 802.11 WLAN will be split into smaller units suitable

for the circuit size. Packets smaller than the specified fragmentation threshold value however are

not fragmented.

Values between 256 and 2346 can be entered but should remain at a default setting of 2346.

Setting the Fragmentation Threshold too low may result in poor performance.

RTS Threshold

Request To Send (RTS) specifies the packet size that exceeds the specified RTS threshold, which

then triggers the RTS/CTS mechanism. Smaller packets are sent without using RTS/CTS. The default

setting of 2347 (max length) will disables the RTS Threshold.

DTIM Interval

Delivery Traffic Indication Message (DTIM) is also known as Beacon Rate. The entry range is a value

between 1 and 65535. A DTIM is a countdown variable that informs clients of the next window for

listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast

messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP Clients hear

the beacons and awaken to receive the broadcast and multicast messages. The default is 1.

Beacon Interval

The amount of time between beacon transmissions in is milliseconds. The default is 100 ms and the

acceptable range is 1 – 65535. The beacon transmissions identify the presence of an access point.

By default, network devices passively scan all RF channels listening for beacons coming from access

points. Before a station enters power save mode, the station needs the beacon interval to know

when to wake up to receive the beacon.

Global Max Clients

Here you have the option of setting the limit of the number of clients who can connect to your

wireless network

Xpress Technology

Broadcom’s Xpress™ Technology is compliant with draft specifications of two planned wireless

industry standards. It has been designed to improve wireless network efficiency. Default is disabled

Transmit Power

The option of decreasing the transmitting power of your wireless signal
