Get ready to experience the speed and flexibility of a wireless network using your WA 100 Wireless Access Point. A brief overview of the basics of wireless networking can be found here. For more information you can also refer to the Glossary. 6

39 3.1 Wireless Network Modes A wireless local area network (WLAN) is similar to a regular local area network (LAN). In this case however, there are no cables present and the connection is established through wireless channels. Computers in a WLAN share the same frequency channel and use the same wireless connection name called SSID (Service Set Identifier). Unlike wired networks, wireless networks have two different setup modes: Infrastructure and Ad-Hoc. A Wireless Infrastructure network configuration is essentially a WLAN that incorporates a Wireless Access Point / Router. In order to setup a Wireless Infrastructure Network such as the example shown above, you will need the following: 1. A Wireless Access Point that creates a wireless infrastructure network. 2. Wireless clients equipped with wireless networking devices such as the WU 100 Wireless USB Adapter. 3.2 Wireless Standards The IEEE g is an extension of the older b standard. It increases the data rate up to 54 Mbps within the 2.4GHz band, utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by dividing the communication channel into a number of sub-channels. Every user transmits using one "dedicated" sub-channel. This is a very efficient way of utilizing the available frequencies and as a result this technique enables fitting an amazing amount of data into a relatively small bandwidth. In addition, the new multiplexing technology deals with network traffic issues quite efficiently, minimizing the possibility of packet collisions. 7

40 The new IEEE g wireless networking standard also offers a range of highly sophisticated network security features. The standard supports the Wired Equivalent Privacy (WEP) security feature, introduced in b. WEP is an encryption scheme that introduces a secret key as an additional security measure for preventing unwanted users from accessing a wireless network. The new Wi-Fi standard also features the new WPA standard, which is designed for enterprise wireless networking solutions. Its variant WPA-PSK is ideal for small office - home office use and is set to improve the WEP security feature on WLANs. It incorporates a passphrase to prevent unwanted stations from linking to an Access Point / Router. Another important feature of the IEEE g is its' backward compatibility with b devices. Both standards operate in the same frequency band and the new wireless standard is able to switch from OFDM to DSSS, the transmission technology used in 802.1b, when devices using that standard are present in a WLAN. This implies that if you already have a wireless network based on the IEEE b standard, the devices in that network will interoperate without problems with the g devices at speeds up to 11Mbps. You will find a more analytical description of the security and networking features available in the "Configuring the Access Point" chapter of this manual. 3.3 Access Point Connection Modes There are four Access Point Connection Modes AP Mode When enabling the AP Mode (Access Point Mode), the device connects all the wireless stations together and, perhaps, to an additional wired network. If the Access Point has access to an Internet connection, then all the associated clients will have access to this connection. 8

41 3.3.2 Bridge Mode While acting as Bridges, AP1 and AP2 can communicate with each other through the wireless interface. Thus Station 1 can communicate with Station 2 and both Station 1 and Station 2 are able to access the Internet if only AP1 or AP2 has an Internet connection Client Mode There are two types of Client Mode connection: ñ Infrastructure If set to Client (Infrastructure) mode, the device is configured to work as a wireless client of an existing AP that creates an Infrastructure Network. The AP is directly connected to a PC (wired connection) and provides connectivity to an existing WLAN created by another AP. 9

42 If the AP has Internet connection, then the AP1 as well as its' wired client will have access to the Internet. This mode, essentially transforms the device into a Wireless Ethernet Adapter set to connect to an Infrastructure Network. ñ Ad-hoc If set to Client (Ad-Hoc) mode, the device is configured to work as a wireless client of an existing Ad-Hoc Network. The AP is directly connected to a PC (wired connection) and provides connectivity to an existing Ad-Hoc WLAN created by other wireless clients. If the clients have Internet connection, then the AP as well as its' wired client will have access to the Internet. This mode, essentially transforms the device into a Wireless Ethernet Adapter set to connect to an Ad-Hoc Network. 10

43 3.3.4 Repeater Mode You can use this feature to build up a large wireless network in large spaces like airports, hotels, schools etc. This feature is also useful when users want to bridge networks between buildings where it is impossible to deploy network cable connections between these buildings. Note: To enable the Client, Bridge and Repeater modes, all APs related must have WDS enabled and must add each other as WDS Access Point. (e.g. Add AP2's MAC address to AP1's "WDS AP List" and vice versa). 4 Hardware Installation Procedure ñ Attach the Antenna at the Rear Panel of your Access Point. ñ Plug the Access Point to a power supply socket. ñ Connect to the Access Point There are two ways to connect to the Access Point: Wireless Connection: Install a Wireless Ethernet Adapter such as the Crypto WP 100E Wireless PCI Card. Configure the WP 100E and connect to the Access Point wirelessly. Wired Connection: Connect the Access Point to the Ethernet Adapter of your PC, using an RJ-45 Ethernet Cable. 11

You can also see the IP address, subnet mask, default gateway value and MAC address of your WA

46 5.1.2 Statistics This page provides information on the sent and received packets, both at the Ethernet as well as the Wireless interface Active Clients This page shows the clients associated with the Access Point. When the device is set to DHCP server, the clients' IPs are visible. If DHCP server is disabled, then the MAC addresses are only available. The page also provides information on the connection with each client. 5.2 Wireless This is a set of pages that give you access to the Wireless settings of the AP. You can configure every little detail of the device in order to adjust it to your needs and preferences. All the settings are described and explained below. For additional information, you can refer to the Glossary. 14

47 5.2.1 Basic Settings Disable Wireless LAN Interface: Check the box to disable the Wireless LAN Interface. If you do this, the device will not be visible by any wireless station. Band: You can choose one mode from the following: ñ 2.4GHz (B): b supported rate only. ñ 2.4GHz (G): g supported rate only. ñ 2.4GHz (B+G): b supported rate and g supported rate. Mode: The Wireless Access Point can support four modes: AP, Client, Bridge and Repeater Network Type When in Client mode, you can select between Ad-Hoc and Infrastructure. SSID: Service Set Identifier, which is a unique name shared among all clients and nodes in a wireless network. The SSID must be identical for each client and node in the wireless network. This means that all computers using the same SSID belong to the same network. It is case-sensitive and must not exceed 32 characters. Region Domain: The AP's domain determines the number of available channels. Channel Number: Allows you to set the wireless channel manually or automatically. All stations communicating with the Access Point must use the same channel. Enable Mac Clone (Single Ethernet Client): If your ISP restricts service to PCs only, use the MAC Clone feature to copy a PC Media Access Control (MAC) address to your router. This procedure will cause the router to appear as a single PC, while allowing online access to multiple computers on your network. 15

48 Click "Apply Changes" to save the new settings on the screen. Click "Reset" to discard the data you have entered since the last time you pressed "Apply Changes" Advanced Settings This page contains a set of settings mainly focused on advanced users. You can use this page to modify these settings for network performance fine-tuning. Authentication Type: The authentication type is set to Open System by default. There are three options: Open System, Shared Key and Auto. All the nodes and hosts on the network must use the same authentication type. Open System authentication is a null authentication algorithm. Any station that requests authentication receives it. When Shared Key authentication is enabled, the Access Point / Router sends a packet to the client. If the packet is correctly encoded then the client is authenticated. Fragmentation Threshold: To set the number of bytes that constitute the fragmentation boundary of packets. The use of the appropriate fragmentation threshold can increase the quality of the wireless network, because by sending smaller frames, you can reduce the possibility of packet collisions due to network traffic. However, if the threshold is set too low, then the throughput may be reduced. High fragmentation threshold has the opposite effect. Default value: 2346 bytes. RTS Threshold: To set the size of RTS packet size. Request To Send is a signal sent from the transmitting station to the receiving station requesting permission to transmit. If the packet that the Access Point is transmitting is larger than the threshold, it will initiate the RTS function. If the packet size is equal to or less than the threshold, the access point will not enable RTS. You can use a threshold of around 500. If it is set too high, then packet collisions can affect connection quality. If it set too low, then the throughput may be reduced. Default value: 2347 bytes. 16

49 Beacon Interval: To set the period of time in milliseconds that the Access Point sends out a beacon. Default value: 100msec. Data Rate: When Auto is enabled the device will select the optimal transmission rate. If obstacles or interference are present, the system will automatically fall back to a lower rate. You can also, select a data rate value manually. Preamble: A preamble is a signal used in a wireless environment for synchronization purposes. In a "noisy" network environment, the Preamble Type should be set to Long. Short is intended for applications where minimum overhead is desired Broadcast SSID: While SSID Broadcast is enabled, any potential wireless clients will be able to communicate with the access point. For security reasons, you may want to disable the SSID broadcast option in order to allow only those wireless clients that know the SSID value to communicate with the access point. IAPP: The IAPP (Inter Access Point Protocol) is an extension of the IEEE standard and it is designed to support interoperability, mobility, handover and coordination among WLAN APs. It provides a means to make APs communicate with each other g Protection: The g standard includes a protection mechanism to ensure mixed b and g operation. If no such kind of mechanism exists, the two standards may mutually interfere and decrease network's performance. Click "Apply Changes" to save the new settings on the screen. Click "Reset" to discard the data you have entered since the last time you pressed "Apply Changes" Security This page allows you to configure the security features supported by your Access Point. 17

50 Encryption: If WEP is selected, users will have to Set WEP keys either manually, or select to Use 802.1x Authentication, in order to make the RADIUS server issue the WEP key dynamically. WEP Key: You may want to set a WEP Key when you want all the clients in the wireless network to use a secret key in order to connect to the network. A WEP Key can be entered in both Open System and Shared Key authentication modes (in both cases a secret key is used but the authentication procedure is different). To disable WEP security, click on the "Disable" option. To enable WEP security, select the key length to be 64bits or 128 bits. When the key length is selected, the key value must be entered in either ASCII or HEX format. Example: WEP Key format HEX 64bits: WEP Key format ASCII 64bits: 1234AC9E01 PG7+A Note: When WEP security is enabled, all the wireless clients that wish to connect to the Access Point must also have WEP enabled with the identical WEP Key value entered. Click "Apply Changes" to save the new settings on the screen. Click "Reset" to discard the data you have entered since last time you pressed "Apply Changes". 18

51 WPA (TKIP/AES/Mixed): If WPA is selected, you can select the Authentication mode between Enterprise (RADIUS) and Personal (Pre-shared Key). You can use a 1 to 63 characters string to set the password or you can leave it blank. In this case, the 802.1x Authentication will be activated. Make sure that the same password is used on the client's end. Group Key Life Time: Enter the number of seconds that will elapse before the group key changes automatically. The default value is seconds. Port: Enter the RADIUS Server's port number provided by your ISP. The default is IP Address: Enter the RADIUS Server's IP Address provided by your ISP. Password: Enter the password that the AP shares with the RADIUS Server. Click "Apply Changes" to save the new settings on the screen. Click "Reset" to discard the data you have entered since the last time you pressed "Apply Changes" Access Control When Wireless Access Control Mode is enabled, only those clients whose wireless MAC addresses are listed in the access control list can access this Access Point. This MAC Filter function is an additional security feature. If the list contains no entries with this function being enabled, then no clients will be able to access this Access Point. You can press "Delete Selected" or "Delete All" to delete MAC addresses from the table. Comment: You may also enter up to 20 characters as a remark to the previous MAC Address. 19

59 8 Glossary 802.1x: The IEEE 802.1x is a standard for user authentication on networks. Access Point: A hardware device or a computer's software that seamlessly connects wired and wireless networks. Ad-Hoc: An independent wireless LAN network formed by a group of computers equipped with wireless network adapters. ADSL: Asymmetric Digital Subscriber Line is a new technology that allows more data to be sent over existing copper telephone lines. ADSL supports data rates from 1.5 to 8 Mbps downstream and from 16 to 640 Kbps upstream. AES: Advanced Encryption System is an encryption technique that utilizes a symmetric 128-Bit block data encryption. ASCII: American Standard Code for Information Interchange is a code for representing characters as numbers. Each letter is represented as a number from 0 to 127. ASCII was originally developed for communications and uses only seven bits per character. Since computers use 8-bit byte (256 character combinations) and ASCII uses only the first 128 (0-127), the second set of 128 characters ( ) are technically not ASCII, but are typically used for different language and math symbols representation. Authentication: The process of identifying a network client usually based on a username and password. Beacon: A beacon is a packet broadcasted by the Access Point / Router in order to keep the network synchronized. CCX: The Cisco Compatible extensions Program for WLAN devices, is a program that provides compatibility testing for compliance with proprietary Cisco wireless features. Channel: A channel is a separate path through which signals can flow. CTS: Clear To Send is a confirmation message sent from the receiving station to the transmitting station granting permission to transmit. DHCP: Dynamic Host Configuration Protocol is a protocol that automatically assigns dynamic IP addresses to devices on a network. DSSS: Direct Sequence Spread Spectrum is a transmission technology where a data signal is combined with a higher data rate bit sequence. The additional bits increase the signal's resistance to interference. DTIM: Delivery Traffic Indication Message is a message informing clients about the next time window for listening to broadcast and multicast messages. It is essentially a count of the number of beacon frames that must occur before the access point sends the buffered multicast frames. EAP: Extensive Authentication Protocol is a framework for extending authentication techniques in PPP (Point-to-Point Protocol) a protocol that is commonly used for dialup connections. EAP opens up the possibilities to use a range of new authentication protocols, including token cards, one-time passwords etc. Encryption: The modification of data using a secret code. Encryption is an effective way to achieve data security. Ethernet: A local-area network (LAN) architecture developed by Xerox Corporation in cooperation with DEC and Intel in The most common Ethernet systems are called 10BASE-T and provide transmission speeds up to 10 Mbps. Fast Ethernet (100BASE-T) provides transmission speeds up to 100 megabits per second. Gigabit and 10-Gigabit 27

60 Ethernet provide even higher transmission speeds of 1 gigabit per second and 10 gigabits per second respectively. Fragmentation: When the size of a transmitted packet exceeds a certain limit allowed by the network medium it is broken into several segments. The procedure is called fragmentation. Low fragmentation thresholds result in smaller frames and can tackle with packet collision problems due to network traffic. Setting the threshold too low can lead to, reducing throughput due to the additional headers applied to each. High fragmentation threshold has the opposite effect. Gateway: A device that interconnects networks. HEX: Hexadecimal is the base-16 number system. IAPP: The IAPP is an extension of the IEEE standard and it is designed to support interoperability, mobility, handover and coordination among WLAN APs. It provides a means to make APs communicate with each other. IEEE: Institute of Electrical and Electronics Engineers. The IEEE is an organization that is best known for developing standards for the computer and electronics industry. Infrastructure: A Wireless Infrastructure network configuration is essentially a WLAN that incorporates a Wireless Access Point / Router. ISM Band: Industrial, Scientific and Medical Band is the GHz frequency band. LEAP: Lightweight Extensible Authentication Protocol is a part of the CCX features. It provides username / password-based authentication between a wireless client and a RADIUS server. LED: Light Emitting Diode, an electronic device that lights up when electricity is passed through it. MAC Address: Media Access Control Address is a unique HEX number assigned by the manufacturer to any Ethernet networking device. Node: A network junction or connection point, typically an Access Point / Router. OFDM: Orthogonal Frequency Division Multiplexing is a modulation scheme that works by dividing the communication channel into a number of sub-channels that are spaced apart at precise frequencies. This spacing provides the "orthogonality" in this technique which allows the transmitter and the receiver to communicate using a "dedicated" subchannel. The benefits of OFDM are high spectral efficiency and resiliency to interference. Open Authentication: Open System authentication is a null authentication algorithm. Any station that requests authentication receives it. If the key that the station is using is not correct, then further communication is not possible Packet: A set of data routed between an origin and a destination in a network. PEAP: Protected Extensible Authentication Protocol authenticates wireless LAN clients using only server-side digital certificates. It is a protocol developed jointly by Microsoft, RSA Security and Cisco for transmitting authentication data, including passwords, over wireless networks. Preamble Type: A preamble is a signal used in network communications to synchronize the transmission timing between two or more systems. RADIUS: Remote Authentication Dial-In User Service is an authentication and accounting system used by many Internet Service Providers (ISPs). When you dial in to the ISP you must enter your username and password. This information is passed 28

61 to a RADIUS server, which checks that the information is correct, and then authorizes access to the ISP system. RTS: Request To Send is a signal sent from the transmitting station to the receiving station requesting permission to transmit. Shared Key Authentication: When Shared Key authentication is enabled, the Access Point / Router sends a packet to the client. The client uses a secret key in order to encode the packet and retransmits the encoded information back to the Access Point / Router. If the packet is correctly encoded then the client is authenticated. SSID: Service Set Identifier is a unique name shared among all clients and nodes in a wireless network. The SSID must be identical for all clients and nodes within a wireless network. Subnet Mask: The method used for splitting IP networks into a series of subgroups, or subnets. TKIP: Temporal Key Integrity Protocol. The TKIP works with a RADIUS server and changes the network keys every packets, ensuring greater security. TLS: Transport Layer Security is a protocol that guarantees privacy and data integrity between client / server applications communicating over the Internet. It is application protocol-independent, allowing higher-level protocols to be setup on top of it transparently. Throughput: The amount of data transferred from one place to another or processed in a specified amount of time. WEP: Wired Equivalent Privacy is an encryption scheme that is used in wireless data communication and prevents stations that do not have the correct WEP key from linking to an Access Point / Router. WPA: Wi-Fi Protected Access is a standard designed to improve the WEP security feature on WLANs. It incorporates TKIP and EAP. WPA-PSK: Wi-Fi Protected Access Pre Shared Key is a variation of the WPA standard that is designed for small office - home use. It incorporates a Pre Shared Key, called passphrase to prevent unwanted stations from linking to an Access Point / Router. 29
