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

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
