112.3.2 Basic Wireless On this page you can configure the basic 802.11g wirelesssettings. Any new settings will not take effect until the bridgeis rebooted.Figure 2: Basic WirelessWireless Network Type Select ‘Infrastructure’ to connect to a wireless access point, select ‘Ad-hoc’ to connect to another bridge or wireless station.Wireless Network Name (SSID)
12 This is the name of the wireless access point that this bridge will associate to. Leave this field blank to associate to any access point.Desired BSSID This provides manual selection for the desired Access Point to join with. The SSID for the Access Point still has to match. You can copy and paste the desired MAC address from the Info page.Channel This is the radio channel that is used in ad-hoc mode. This setting has no effect in infrastructure mode. If you experience interference (e.g. lost connections or slow data transfers) you may need to try different channels to see which is the best.Transmission rate (Mbits/s) This is the speed at which the bridge will transmit data. Normally you should select ‘best’ here, although if your wireless network is unusually noisy or quiet you may which to use a fixed low or high rate.Wireless Mode Wireless mode allows the user to select whether thisBridge will connect to an 802.11g only network, an802.11b only network, or both types of networks.
132.3.3 Security and Encryption Settings On this page you can set the 802.11g security and encryp-tion options. Any new settings will not take effect until thebridge is rebooted.Figure 3: Security and Encryption Settings

17 Cloning Mode This feature controls the MAC Address of theBridge as seen by other devices (wired or wireless). If set to “Ethernet Client”, the MAC Address fromthe first Ethernet client that transmits data throughthe Bridge will be used. This setting is useful whenconnected to an Xbox or if there is only oneEthernet device connected to the bridge. Whenmultiple Ethernet devices are connected to theBridge, it may not be obvious which MAC Address isbeing used. If set to “WLAN Card”, the MAC Address of theWLAN Card (typically written on the back of thecard) will be used. When multiple Ethernet devicesare connected to the Bridge, the MAC Address ofthe Bridge will not change.Fragmentation threshold Transmitted wireless packets larger than this sizewill be fragmented to maintain performance in noisywireless networks.RTS threshold Transmitted wireless packets larger than this sizewill use the RTS/CTS protocol to (a) maintainperformance in noisy wireless networks and (b)prevent hidden nodes from degrading performance.Maximum burst time This is also known as PRISM Nitro (tm)technology. The technology uses fully standards-compliant methods that eliminate collisions in mixed-
18mode networks, while greatly increasing theperformance of both pure 802.11g and mixed802. 11b/g networks. The setting is for the amountof time the radio will be reserved to send datawithout requiring an ACK. This number is in units of microseconds. Theoptimized value for 802.11g only networks is 1400,and the optimized value for 802.11g + 802.11bmixed mode networks is 650. When this number iszero, bursting is disabled.

26802.11 standard802.11, or IEEE 802.11, is a type of radio technology used forwireless local area networks (WLANs). It is a standard that hasbeen developed by the IEEE (Institute of Electrical and Elec-tronic Engineers), http://standards.ieee.org. The IEEE is an in-ternational organization that develops standards for hundreds ofelectronic and electrical technologies. The organization uses aseries of numbers, like the Dewey Decimal system in libraries, todifferentiate between the various technology families.The 802 subgroup (of the IEEE) develops standards for localand wide area networks with the 802.11 section reviewing andcreating standards for wireless local area networks.Wi-Fi , 802.11, is composed of several standards operating indifferent radio frequencies: 802.11b is a standard for wirelessLANs operating in the 2.4 GHz spectrum with a bandwidth of 11Mbps.Another standard, 802.11g, is for WLANS operating in the 2.4 GHzfrequency but with a bandwidth of 54 Mbps. Appendix II Glossary
27802.11bInternational standard for wireless networking that operatesin the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) andprovides a throughput of up to 11 Mbps. This is a very commonlyused frequency. Microwave ovens, cordless phones, medical andscientific equipment, as well as Bluetooth devices, all work withinthe 2.4 GHz frequency band.802.11gSimilar to 802.11b, but this standard provides a throughput ofup to 54 Mbps. It also operates in the 2.4 GHz frequency bandbut uses a different radio technology in order to boost overallbandwidth.Access pointA wireless LAN transceiver or “base station” that can connect awired LAN to one or many wireless devices. Access points canalso bridge to each other.There are various types of access points and base stationsused in both wireless and wired networks. These include bridges,hubs, switches, routers and gateways. The differences betweenthem are not always precise, because certain capabilities associ-ated with one can also be added to another. For example, arouter can do bridging, and a hub may also be a switch. Butthey are all involved in making sure data is transferred from onelocation to another. A bridge connects devices that all use the same kind of protocol.A router can connect networks that use differing protocols. Italso reads the addresses included in the packets and routesthem to the appropriate computer station, working with any otherrouters in the network to choose the best path to send the pack-ets on. A wireless hub or access point adds a few capabilities
28such as roaming and provides a network connection to a varietyof clients, but it does not allocate bandwidth. A switch is a hubthat has extra intelligence: It can read the address of a packetand send it to the appropriate computer station. A wireless gate-way is an access point that provides additional capabilities suchas NAT routing, DHCP, firewalls, security, etc.AES (Advanced Encryption Standard) A chip-based security, has been developed to ensure thehighest degree of security and authenticity for digital information,wherever and however communicated or stored, while makingmore efficient use of hardware and/or software than previousencryption standards. It is also included in IEEE 802.11i standard.Compared with AES, TKIP is a temporary protocol for replacingWEP security until manufacturers implement AES at the hard-ware level.DHCP Dynamic Host Configuration Protocol. This protocol automati-cally configures the TCP/IP settings of every computer on yourhome network.Encryption key An alphanumeric (letters and/or numbers) series that enablesdata to be encrypted and then decrypted so it can be safelyshared among members of a network. WEP uses an encryptionkey that automatically encrypts outgoing wireless data. On thereceiving side, the same encryption key enables the computer toautomatically decrypt the information so it can be read.Ethernet A standard for computer networks. Ethernet networks are con-
29nected by special cables and hubs, and move data around at upto 100 million bits per second (Mbps).ESSID The identifying name of an 802.11 wireless network. Whenyou specify your correct ESSID in your client setup you ensurethat you connect to your wireless network rather than anothernetwork in range. (See SSID.) The ESSID can be called by dif-ferent terms, such as Network Name, Preferred Network, SSIDor Wireless LAN Service Area.Gateway In the wireless world, a gateway is an access point with addi-tional software capabilities such as providing NAT and DHCP.Gateways may also provide VPN support, roaming, firewalls,various levels of security, etc.IEEE802.11 A set of specifications for LANs from The Institute of Electricaland Electronics Engineers (IEEE). Most wired networks con-form to 802.3, the specification for CSMA/CD based Ethernetnetworks or 802.5, the specification for token ring networks.802.11 defines the standard for wireless LANs encompassingthree incompatible (non-interoperable) technologies: FrequencyHopping Spread Spectrum (FHSS), Direct Sequence SpreadSpectrum (DSSS) and Infrared. WECA’s focus is on 802.11b, an11 Mbps high-rate DSSS standard for wireless networks.IP Address IP stands for Internet Protocol. An IP address consists of aseries of four numbers separated by periods, that identifies ansingle, unique Internet computer host. Example: 192.34.45.8.
30ISP Gateway Address (see ISP for definition). The ISP Gateway Address is an IP address for the Internetrouter located at the ISP’s office. This address is required onlywhen using a cable or DSL modem.ISP Internet Service Provider. An ISP is a business that providesconnectivity to the Internet for individuals and other businessesor organizations.LAN Local Area Network. A LAN is a group of computers and de-vices connected together in a relatively small area (such as ahouse or an office). Your home network is considered a LAN.MAC Every wireless 802.11 device has its own specific MAC ad-dress hard-coded into it. This unique identifier can be used toprovide security for wireless networks. When a network uses aMAC table, only the 802.11 radios that have had their MAC ad-dresses added to that network’s MAC table will be able to getonto the network.MAC Address MAC stands for Media Access Control. A MAC address is thehardware address of a device connected to a network. Peer-to-peer network A wireless or wired computer network that has no server orcentral hub or router. All the networked PCs are equally able toact as a network server or client, and each client computer cantalk to all the other wireless computers without having to gothrough an access point or hub. However, since there is no cen-tral base station to monitor traffic or provide Internet access, the
31various signals can collide with each other, reducing overallperformance.SSID A 32-character unique identifier attached to the header ofpackets sent over a WLAN that acts as a password when a mo-bile device tries to connect to the BSS. (Also called ESSID.) TheSSID differentiates one WLAN from another, so all access pointsand all devices attempting to connect to a specific WLAN mustuse the same SSID. A device will not be permitted to join theBSS unless it can provide the unique SSID. Because an SSID canbe sniffed in plain text from a packet, it does not supply anysecurity to the network. An SSID is also referred to as a NetworkName because essentially it is a name that identifies a wirelessnetwork.Subnet Mask A subnet mask, which may be a part of the TCP/IP informa-tion provided by your ISP, is a set of four numbers configuredlike an IP address. It is used to create IP address numbers usedonly within a particular network (as opposed to valid IP addressnumbers recognized by the Internet.TCP/IP Transmission Control Protocol/Internet Protocol. This is thestandard protocol for data transmission over the Internet.TKIP The TKIP (Temporal Key Integrity Protocol), pronounced tee-kip, is part of the IEEE 802.11i encryption standard for wirelessLANs. TKIP is the next generation of WEP used to secure 802.11wireless LANs.TKIP provides per-packet key mixing, a message
32integrity check and a re-keying mechanism, thus fixing the flawsof WEP.WAN A wide area network (WAN) is a geographically dispersedtelecommunications network. The term distinguishes a broadertelecommunication structure from a local area network. A widearea network may be privately owned or rented, but the termusually connotes the inclusion of public (shared user) networks.An intermediate form of network in terms of geography is ametropolitan area network .WEP WEP (Wired Equivalent Privacy) is 802.11’s optional encryp-tion standard implemented in the MAC layer that most radionetwork interface card (NIC) and access point vendors support. Basic wireless security provided by Wi-Fi. In some instances,WEP may be all a home or small-business user needs to protectwireless data. WEP is available in 40-bit (also called 64-bit), or in108-bit (also called 128-bit) encryption modes. As 108-bit en-cryption provides a longer algorithm that takes longer to decode,it can provide better security than basic 40-bit (64-bit) encryption.Wi-Fi An interoperability certification for wireless local area net-work (LAN) products based on the Institute of Electrical andElectronics Engineers (IEEE) 802.11 standard.WLAN Also referred to as LAN. A type of local-area network that useshigh-frequency radio waves rather than wires to communicatebetween nodes.
33WPAWPA is a standards-based, interoperable security specificationthat utilizes Temporal Key Integrity Protocol to provide im-proved over-the-air encryption of wireless data.
