17 SSID: All wireless devices within the ESS or extended wireless LAN use the SSID. This can be any alphanumeric value of up to 32 characters long. Use this to prevent cross communication between two or more WLAN in one area. The SSID should be changed in order to provide some minimum security. Channel: Shows the selected channel that is currently used. (Available channels depends on the country or region you are located.) Authentication: Defines authentication type of the wireless networks, including "Open System" and “Share Key” authentication. The wireless adapter will need to be set to the same authentication type to communicate. Encryption: Indicates your WEP (Wired Equivalent Privacy) settings. WEP encryption can be used to ensure the security of your wireless network. If there is no Encryption exists, the column will show Not USE. Network Type: The network type of the wireless network. An Ad-Hoc wireless LAN is a group of computers each with wireless adapters, connected as an independent wireless LAN. An integrated wireless and wired LAN is called an infrastructure configuration.

19performance. RTS Threshold: The RTS Threshold sets an upper threshold at which point the device will issue an RTS packet. The RTS (Request To Send) packet is used for the purpose of avoiding data collisions on the wireless LAN. There are several trade offs to consider when setting this parameter. Setting this parameter to a small value causes RTS packets to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of other network packets. However, the more often RTS packets are sent, the quicker the system can recover from interference or collisions. Refer to the IEEE 802.11 Standard for more information on the RTS/CTS mechanism. Fragment Threshold: Fragment Threshold defines a threshold above, which the wireless packet will be split up, or fragmented. For a fragmented packet, if transmission of part of it were to be interfered with, only the portion that was successfully transmitted would need to be resent. Throughput will generally be lower for fragmented packets, since the fixed packet overhead consumes a higher portion of the RF bandwidth.

20 4.1.1.3 Authentication & Security Authentication Type: Defines authentication type of the wireless networks, including "Open System" and “Share Key” authentication. The wireless adapter will need to be set to the same authentication type to communicate. Open System: With this setting any station in the Wireless LAN can associate with an Access Point to receive and to transmit data. Share Key: Is when both the sender and recipient share a secret key. Both units use this key for an extended length of time, sometimes indefinitely. Encryption Type: Indicates your WEP (Wired Equivalent Privacy) settings. WEP is disabled by default. WEP : WEP (Wired Equivalent Privacy) is an optional feature of the IEEE 802.11 standard that is used to ensure the security of your wireless network. No Encryption: No any encryption for security.

21WEP Key: Key 1 - Key 4: These four fields can be used to manually enter the encryption keys. This may be necessary if you wish this node to match keys in a different vendor's product. WEP Key length: The 64 or 128-bits Wired Equivalent Privacy Algorithm. You can decide the network key to be encoded by ASCII characters or hexadecimal digitals. A key of 10 hexadecimal characters (0-9, A-F) is required if a 64-bit Key Length was selected. A key of 26 hexadecimal characters (0-9, A-F) is required if a 128-bit Key Length was selected. 4.1.2 Link Status You can see the below status:Status, Current Channel, Current TX Rate, throughput(Kbit/sec), Link Quality, Signal Strength.

22 4.1.3 Site Survey: Click the Site Survey; you can to see the signal strength, channel, Encryption, authentication and network type of available wireless network. The AP MAC address will also be displayed at the Preferred BSSID field. Select the AP you want to connect to and click connect to establish network.

23 4.1.4 Statistics You can see the information of transmit statistics and receive statistics in this screen :

24 4.1.5 Advance: Wireless Mode If there are 802.11b devices in your wireless network, choose b+g mixed mode. If all the devices in your wireless network are 802.11g ones, choose 802.11g mode to get better transfer rate. Tx Burst Enable this function to burst the transmit speed, but it may affect signal quality. Radio off You can stop wireless transmission by clicking this icon. Click again to resume wireless connection.

26 5. Glossary Ad-Hoc Mode An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN adapter, Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. BSS ID A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID. DSSS (Direct-Sequencing Spread-Spectrum) DSSS operate over the radio airwaves in the unlicensed ISM band (industrial, scientific, medical). DSSS uses a radio transmitter to spread data packets over a fixed range of frequency band. Encryption A security method that applies a specific algorithm to data in order to alter the data appearance and prevent other devices from reading the information. Firmware Program that is inserted into programmable read-only memory (programmable read-only memory), thus becoming a permanent part of a computing device. Fragmentation Threshold Value Indicates how much of the network resources is devoted to recovering packet errors. The value should remain at its default setting of 2,432. If you experience high packet error rates, you can decrease this value but it will likely decrease overall network performance. Only minor modifications of this value are recommended. Fragmentation Breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. IEEE The Institute of Electrical and Electronics Engineers IEEE 802.11b/g standard

27 The IEEE 802.11b/g Wireless LAN standards subcommittee formulating standards for the industry. The objective is to enable wireless LAN hardware from different manufacturers to communicate. Infrastructure Mode A client setting providing connectivity to an Access Point. As compared to Ad-Hoc Mode where PCs communicate directly with each other clients set in Infrastructure Mode all pass data through a central Access Point. The Access Point not only mediates Wireless network traffic in the immediate neighborhood but also pro-vides communication with the wired network. An integrated wireless and wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. Roaming The ability to use a wireless device and be able to move from one access point range to another without losing the connection. RTS/CTS Threshold Value Should remain at its default setting of 2,347. A preamble is a signal used to synchronize the transmission timing between two or more systems. A series of transmission pulses is sent before the data to indicate that someone is about transmit data.?This ensures that systems receiving the information correctly when the data transmission starts. Shared Key Is when both the sender and recipient share a secret key. Both units use this key for an extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key may decipher all packets until the key is changed. Signal Strength The signal level indicates the strength of the signal as received at the wireless network interface. SSID (Service Set Identifier) Is the unique name shared among all points in a wireless network. The SSID must be identical for all points in the network. It is case sensitive and must not exceed 32 characters. WEP (Wired Equivalent Privacy) A data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 .11 standard. The optional cryptographic confidentiality algorithm specified by IEEE 802.11 used to provide data confidentiality that is subjectively equivalent to the confidentiality of a wired LAN medium that does not employ cryptographic techniques to enhance privacy. WPA Wi-Fi Protected Access, a specification to improve the security level of wireless networks. It uses 802.1x and EAP to control network access. Temporal Key Integrity Protocol (TKIP) is used to secure data during transmission. ,
