4.3.2 Security Settings

Operation Mode -> Setup -> Security Settings Security settings allow you to use encryption to secure your data from eavesdropping. You can select different security policy to provide association authentication and/or data encryption. The G.DUO features various security policies including WEP, 802.1x, WPA, WPA Personal, WPA2, WPA2 Personal , WPA Mixed.
WEP Encryption is the oldest and most available encryption method. However, it is also the least secure.
Select one of the WEP key for wireless network: There are total of 4 possible keys for WEP encryption. You need to choose which key will be used for encryption. All wireless devices on the same network have to use the same settings. We recommend using WEP Key 1 as in default setting. Authentication: 2 types of Authentication are offered. Open system and Shared key. If you are not sure which one to use, please select Auto. Key Length: The G.DUO offers 64bit and 128 bit for WEP key length. The longer the Key Length, the more secure the encryption is. Key Type: 2 types are available: ASCII and HEX. ASCII is a string of ASCII code including alphabetical characters, space, signs and numbers (i.e. airlivepass12). HEX is a string of 16-bit hexadecimal digits (0.9, a, b, c, d, e, f). All wireless devices on the network must match the exact key length and Key type. Some Wireless clients only allow HEX type for WEP. ASCII-64: This is a key with 64-bit key length of ASCII type. Please enter 5
ASCII Characters if you choose this option. For example, passw HEX-64: This is a key with 64-bit key length of HEX type. Please enter 10 Hexadecimal digits if you choose this option. For example, 12345abcdef ASCII-128: This is a key with 64-bit key length of ASCII type. Please enter 13 ASCII Characters if you choose this option. For example, airlivewepkey HEX-128: This is a key with 128-bit key length of HEX type. Hexadecimal digits if you choose this option. For example, 1234567890abcdef1234567890 Please enter 26

Please enter 26

1234567890abcdef1234567890
WPA-Personal, WPA2-Personal, WPA-Mixed (Pre-Shared Key)
The WPA Personal is also known as WPA-PSK encryption. Wi-Fi Protected Access (WPA) introduces the Temporal Key Integrity Protocol (TKIP) that provides added security. WPA2 adds full support for 802.11i standard and the CCMP (AES Encryption). The WPA-Mixed tries to authenticate wireless clients using both WPA-PSK or WPA2-PSK.
WPA-Enterprise, WPA2-Enterprise, WPA-Mixed Enterprise (Radius)
Wi-Fi Protected Access (WPA) Enterprise uses Radius Server as the authenticator. WPA2 adds full support for 802.11i standard and the CCMP (AES Encryption). The WPA-Mixed tries to authenticate wireless clients using both WPA or WPA2.
4.4.3 Advance (Wireless Settings)
RTS Threshold: RTS/CTS frames are used to gain control of the medium for transmission. Any unicast (data or control) frames larger than specified RTS threshold must be transmitted following the RTS/CTS handshake exchange mechanism. The RTS threshold should have a value between 256-2347 bytes, with a default of 2347. It is recommended that this value does not deviate from the default too much.
Beacon Interval: The device broadcasts beacon frames regularly to announce its existence. The beacon Interval specifies how often beacon frames are transmitted in time unit of milliseconds. The default value is 100, and a valid value should be between 1 and 65,535. AckTimeOut: When a packet is sent out from one wireless station to the other, it will waits for an Acknowledgement frame from the remote station. The station will only wait for a certain amount of time, this time is called the ACK timeout. In most conditions, please put ACKtimeout value at zero(default value). The AP will calculate the ACKtimeout automatically when the value is zero. However, you can also enter the ACKtimeout manually. Preamble Type: A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter. In a "noisy" network environment, the Preamble Type should be set to Long Preamble. The Short Preamble is intended for applications where minimum overhead and maximum performance is desired. If in a "noisy" network environment, the performance will be decreased. IAPP: IAPP (Inter Access Point Protocol) is designed for the enforcement of unique association throughout a ESS (Extended Service Set) and a secure exchange of stations security context between current access point (AP) and new AP during handoff period.
Isolation: Enable Isolation will prevent wireless clients to see each other on the network.

Bootloader Bootloader is the under layering program that will start at the power-up before the device loads firmware. It is similar to BIOS on a personal computer. When a firmware crashed, you might be able to recover your device from bootloader.
Bridge A product that connects 2 different networks that uses the same protocol. Wireless bridges are commonly used to link network across remote buildings. For wireless application, there are 2 types of Bridges. WDS Bridge can be used in Point-to-Point or Point-to-Multipoint topology. Bridge Infrastructure works with AP mode to form a star topology.
Cable and Connector Loss: During wireless design and deployment, it is important to factor in the cable and connector loss. Cable and connector loss will reduce the output power and receiver sensitivity of the radio at connector end. The longer the cable length is, the more the cable loss. Cable loss should be subtracted from the total output power during distance calculation. For example, if the cable and connector loss is 3dBm and the output power is 20dBm; the output power at the cable end is only 17dBm.
Client Client means a network device or utility that receives service from host or server. A client
device means end user device such as wireless cards or wireless CPE.
CPE Devices CPE stands for Customer Premises Equipment. A CPE is a device installed on the end user's side to receive network services. For example, on an ADSL network, the ADSL modem/router on the subscriber's home is the CPE device. Wireless CPE means a complete Wireless (usually an AP with built-in Antenna) that receive wireless broadband access from the WISP. The opposite of CPE is CO.
CTS Clear To Send. A signal sent by a device to indicate that it is ready to receive data.
DDNS Dynamic Domain Name System. An algorithm that allows the use of dynamic IP address for hosting Internet Server. A DDNS service provides each user account with a domain name. A router with DDNS capability has a built-in DDNS client that updates the IP address information to DDNS service provider whenever there is a change. Therefore, users can build website or other Internet servers even if they don't have fixed IP connection.
DHCP Dynamic Hosting Configuration Protocol. A protocol that enables a server to dynamically assign IP addresses. When DHCP is used, whenever a computer logs onto the network, it automatically gets an IP address assigned to it by DHCP server. A DHCP server can either be a designated PC on the network or another network device, such as a router.
DMZ Demilitarized Zone. When a router opens a DMZ port to an internal network device, it opens all the TCP/UDP service ports to this particular device. The feature is used commonly for setting up H.323 VoIP or Multi-Media servers.
