NETCOMM LIBERTY™ SERIES - 3G WiFi Router
5.2 Security
This Router includes a number of security options that provides you with a secure connection to a 3G network. State-of-the art security
includes:
• WEP / WPA / WPA2 data encryption
• SPI Firewall
• VPN Pass-Through
• MAC address IP ltering
• Authentication protocols — PAP / CHAP
You can also authenticate or encrypt your service using the WEP algorithm, which provides protection against unauthorized access such
as eavesdropping.
By default, WPA-PSK security is specied for the Network authentication type in use.
The following screen appears when Security is selected. The Security page allows you to congure security features of your Router’s
wireless LAN 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 Save/Apply to congure the wireless security options.
OPTION DESCRIPTION
Select SSID Your Service Set Identier (SSID), sets your Wireless Network Name. You can connect multiple devices
including Laptops, Desktop PCs and PDAs to your Wireless Router. To get additional devices connected,
scan for a network, and locate the SSID shown on your Wireless Security Card. If the SSID does not match,
access is denied.
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 elds.
WEP Encryption will also be enabled)
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 dened, only one can be used at
anyone time. Use the network key found in the drop-down list.
Encryption Strength This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the
number of binary bits comprising the key. This means that keys with a greater number of bits have a greater
degree of security and are considerably more difcult to crack.
Encryption strength can be set to either 64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or
10 hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26 hexadecimal numbers.
NOTE: Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data.
Click Apply/Save to save any changes you have made to your Wireless security.
Please note: You will need to recongure and reconnect any wirelessly connected devices after changing the security on your
wireless network.
