IMPORTANT NOTE: FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. The Wireless Technology Standard The Wireless Access Point utilizes the 802.11b and the 802.11g standards. The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54 Mbps (108Mbps in Super G mode) within the 2.4GHz band, utilizing OFDM technology. This means that in most environments, within the specified range of this device, you will be able to transfer large files quickly or even watch a movie in MPEG format you’re your network without noticeable delays. This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of cross talk (interference) in signal transmissions. The AP will automatically sense the best possible connection speed to ensure the greatest speed and range possible. 802.11g offers the most advanced network security features available today, including: WPA, TKIP, AES and Pre-Shared Key mode. Planning Your Wireless Network Network Topology A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless network must be configured to share the same radio channel. Several PCs equipped with wireless cards or adapters can communicate with one another to form an ad-hoc network. The wireless adapters also provide users access to a wired network when using an access point or wireless router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless router. An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may double the effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data within a network, the effective transmission range in an infrastructure network may be doubled. Roaming Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they both share the same channel and SSID. Before enabling you consider roaming, choose a feasible radio channel and optimum access point position. Proper access point positioning combined with a clear radio signal will greatly enhance performance. Network Layout The AP Access Point has been designed for use with 802.11g and 802.11b products. With 802.11g products communicating with the 802.11b standard, products using these standards can communicate with each other. The Access point is compatible with 802.11g and 802.11b adapters, such at the PC Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB connectivity. These wireless products can also communicate with a 802.11g or 802.11b wireless Print Server. When you wish to connect your wired network with your wireless network, the Access Point’s network port can be used to connect to any of switches or routers. Installation Considerations The AP lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines: Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise. Keep the number of walls and ceilings between the AP and other network devices to a minimum - each wall or ceiling can reduce your AP’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. Be aware of the direct line between network devices. A wall that is 1.5 feet thick(.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or z ceiling (instead of at an angle) for better reception. Building materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials.

Make sure the wiring is correct. In 10Mbps operation, Category 3/4/5 cable can be used for connection. To reliably operate your network at 100Mbps, you must use Category 5 cable, or better Data Grade. 11 AP Configuration Using Locator While entering the Locator utility, the Locator will automatically search the AP available on the same network. Locator will show the Device Name, Device Type, IP Address, Ethernet MAC Address and Firmware Version in first page. Before start using Locator, make sure you disable personal firewall installed in you PC. (Ex. Windows XP personal firewall) To setup the access point, just simply click on the “Setup Wizard” icon and the Locator configuration utility will lead you step by step to finish all the settings. After click on the “Setup Wizard” icon, the first page show up will be “Login”. Please input your user name and password into the column. Default user name and password ex-factory as below: User Name: Admin Password: (leave blank) 12 After type in correct user name and password, the utility will lead you into “IP Setting” page. Here you can choose to get IP from a DHCP server or specify IP address manually. Choose to obtain an IP address from DHCP server if your environment or ISP provide DHCP server. Otherwise, you can manually setup IP address. Keep the default IP setting if you are not familiar with TCP/IP setting. After you finish IP setting, click on “Next” to continue the configuration. 13 You may assign any name to the Access Point. Memorable, Unique names are helpful especially if you are employing multiple access points on the same network. The device name needs to be less than 32 characters. After verify the name you input and click “Next” to continue the setting. 14 The following page is operation mode setting. Default operation mode is Access Point, this connects your wireless PCs and devices to a wired network. In most cases, no change is necessary. You can switch operation mode to Wireless Client or Repeater mode depends on your application. Wireless Client mode can allow AP act as a client within its range. Your Ethernet devices behind the AP can connect to remote AP. Repeater mode is able to talk with one remote access point within its range and retransmit its signal. Choose repeater mode if you want to extend the range of your original AP. 15 Here we choose the AP to work in Access Point mode, and then the utility will ask for SSID, Channel and Wireless Mode. Keep the default value if you do not have special requirement for these settings. SSID: Generic Channel: Smart Select Wireless Mode: 2.4GHz 54Mbps (802.11g) 16 Next page is wireless security setting; you can choose different level of security support for your wireless environment here. The default value is “Disable” which means anybody who can receive the wireless signal can link to your access point. Once you choose different security level, your wireless LAN card will also need to have corresponding security setting as well. Keep default value if you are not familiar with wireless security setting. With default setting “Disable” may cause your wireless network vulnerable to hacker or even neighbor since there is not any encryption or authentication protect. But this setting will help you to get best connectivity with most wireless clients available. 17 After finish the security setting, you can click on the “Finish” button to jump to confirmation page. In the confirmation page, the Locator utility will show you the new settings and old settings in a comparison chart. If you agree with all the changes in the table, just easily click on the “OK” button. All settings will take effect immediately after system reboot. 18 Congratulations!! Now you have finished all setting needed to the access point by just few mouse clicks. 19 AP Configuration Using Web User Interface Before Setup...

The Locator will launch a default browser for you and lead you into web UI directly 20 21 Wireless Configuration - AP Mode System Status – The first page appears in main page will show “System Status -> System Summary” automatically, you can find detail system configuration in this page including System Information – This will display system name and both Ethernet MAC address and Wireless MAC address. Current country setting and firmware version will also be available here. Current IP Settings – This section show current IP address setting including IP address, Subnet Mask, Default Gateway and DHCP status. Current Wireless Settings – This area show current wireless setting including operation mode, wireless mode, SSID, channel and security setting. System Configuration – Now you can start to configure the system. In System Properties page, you can config Device Name – You may assign any name to the Access Point. Memorable, Unique names are helpful especially if you are employing multiple access points on the same network. The device name needs to be 22 z less than 32 characters. After verify the name you input and click “Apply” to save the setting. Country/Region – Here you can set the AP to follow different country and region regulation. The AP can support Operation Mode - The default operation mode is Access Point, this connects your wireless PCs and devices to a wired network. In most cases, no change is necessary. You can switch operation mode to Wireless Client or Repeater mode depends on your application. Wireless Client mode can allow AP act as a client within its range. Your Ethernet devices behind the AP can connect to remote AP. Repeater is able to talk with one remote access point within its range and retransmit its signal. Choose repeater mode if you want to extend the range of your original AP. Administration – In the administration page, you can modify “Administrator Name” and “Password”. Changing the sign-on user name and password is as easy as typing the string you wish in the column. Then, type the password into second column to confirm. Click “Apply” to finish the procedure. Be sure you noted the modification before apply all changes. 23 IP Settings – IP Setting page can configure system IP address. Default IP address is 192.168.x.x and Subnet Mask is 255.255.0.0. You can manually input IP address setting or get an IP from a DHCP server. IP Network Setting – Here you can choose to get IP from a DHCP server or specify IP address manually. Choose to obtain an IP address from DHCP server if your environment or ISP provide DHCP server. Otherwise, you can manually setup IP address. IP Address – The IP address need to be unique to your network. We would like to recommend you stay with default IP address 192.168.x.x. This is private address and should work well with your original environment. IP Subnet Mask – The Subnet Mask must be the same as that set on your Ethernet network. Default Gateway – If you have assigned a static IP address to the Access Point, then enter the IP address of your network’s Gateway, such as a router, in the Gateway field. If your network does not have a Gateway, then leave this field blank. 24 Wireless Network At Wireless Network page can set “SSID” / “Wireless Mode” and “Channel”. AP supports not only standard 11b/g but also 108M SuperG. (Note: 108 M SuperG only works with Atheros® based 11a/g solution) Wireless Network Name (SSID) - The SSID is the unique name shared among all points in a wireless network. The SSID must be identical for all points in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any keyboard character. Make sure this setting is the same for all points in your wireless network. For added security, you should change the SSID from the default name Generic, to a unique name. Suppressed SSID – This option can hide the SSID not available from site survey tool. Enable this function only if you do not want the Access Point to be found by others. Wireless Mode – Default setting is “2.4GHz 54Mbps (802.11g)”. This will support all 802.11b/g clients connect to the AP. You can choose “2.4GHz 11Mbps (802.11b)” in wireless mode column if your environment only have 802.11b clients. The final selection “2.4GHz 108Mbps (802.11 SuperG)” supports high speed 108Mbps SuperG function. In order to support SuperG 108M transmission, all wireless clients will need to be Atheros® solution. Channel / Frequency – Select the appropriate channel from the list provided to correspond with your network settings. All points in your 25 wireless network must use the same channel in order to function correctly. The default setting is “SmartSelect” means the system will pick best channel for you automatically. Stay with default setting if you do not have special request on channel selection. Wireless Security The wireless security settings configure the security of your wireless network. There are three wireless security mode options supported by the Access Point: WEP, WPA-PSK and WPA. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent Privacy.) In Wireless Security page, you can configure the AP to work with No Security, WEP, WPA-PSK and WPA security mode. Once you setup the AP to work in security mode, all wireless stations will also need to have corresponding settings. System default setting is “No Security”. 26 WEP is a basic encryption method, which is not as secure as WPA. To use WEP, you will need to select a default transmit key and a level of WEP encryption, Authentication type – Select “Open System” to communicate the key across the network. Select “Share Key” to limit communication to only those devices that share the same WEP settings. Shared keys input type – Select HEX or ASCII depends on your preference Key table – You can input 4 different WEP encryption keys into the table and by choosing the radio button to decide which one is valid now. The AP supports 64, 128 and 152bit key length. The longer key we choose usually means the encryption is stronger. After all changes are made, be sure to click on “Apply” to make sure all changes are saved into system. 27 WPA-PSK stands for Wi-Fi Protected Access – Pre-Shared Key. WPA-PSK is design for home users who do not have RADIUS server in their network environment. WPA can provide better security level than WEP without difficult setting procedure. PassPhrase - Enter a WPA Shared Key of 8-63 characters. The Shared Key should be also applying the clients work in the same wireless network. Cipher Type - WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the type of algorithm, TKIP or AES. Group Key Renewal period - Enter a number of seconds which instructs the Access point how often it should change the encryption keys. Usually the security level will be higher if you set the period shorter to change encryption keys more often. Default value is 1800 seconds, set 0 in Group Key Renewal period to disable key renewal. Remember to click on “Apply” to make sure all changes are made before leaving this page. 28 WPA option features WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Access Point.) RADIUS Server – Here enter the IP address of your RADIUS server. RADIUS Port – Port number for RADIUS service, default value is 1812 RADIUS Secret – RADIUS secret is the key shared between Access Point and RADIUS server. Cipher Type – WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the type of algorithm, TKIP or AES. Group Key Update Interval – This column indicate how often should the Access Point change the encryption key. 29 Wireless Advance Settings The page below can help users to configure advanced wireless setting. Before making any changes at this page, please check your wireless settings on other system as well, as these changes will alter the effectiveness of the Access Point. In most cases, these settings do not need to be changed. Data Rate – In data rate column you can select all bit rate supported in current operation mode. Default value is “best” means the system will automatically adjust the connection speed dynamically according to your current link status. Transmit Power – You can reduce RF output power by selecting Half (-3dB) / Quarter (-6dB) / Eighth (-9dB) / Minimum. To change transmit power may decrease your wireless signal coverage. Beacon Interval (20-1000) – This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Access Point to keep the network synchronized. A beacon includes the wireless LAN service area, the AP address, the Broadcast destination address, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). Data Beacon Rate (DTIM) (1-16384) – This value indicated how often the Access Point sends out a Delivery Traffic Indication Message. Lower settings result in more efficient networking, while preventing your PC from dropping into power-saving sleep mode. Higher settings allow your PC to enter sleep mode, thus saving power, but interferes with wireless transmissions. Fragment Length (256-2346) – This specifies the maximum size a data packet will be before splitting and creating a new packet and should remain at its default setting of 2,346. A smaller setting means smaller packets, which will create more packets for each transmission. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. Only minor modifications of this value are recommended. RTS/CTS Threshold (256-2346) – This setting determines how larget a packet can be before the Access Point coordinates transmission and reception to ensure efficient communication. This value should remain at its default setting of 2,346. Should you encounter inconsistent data flow, only minor modifications are recommended. 30 z Short Preamble – Preambles are a sequence of binary bits that help the receivers synchronize and ready for receipt of a data transmission. Some older wireless systems like 802.11b implementation use shorter preambles. If you are having difficulty connecting to an older 802.11b device, try to enable short preamble. Protection Mode – Protection Mode should remain default value (Auto) unless you are having severe problems with your 11g Wireless LAN products not being able to transmit to the Access Point in an environment with heavy 802.11b traffic. To enable this function boosts the Access Point’s ability to catch all 11g Wireless transmissions but will severely decrease performance. Remember to click on “Apply” to make sure all changes are made before leaving this page. Wireless Station List Wireless Station List page can help user identify current clients who already associated to the AP. You can also click on the MAC address column then the system will show the detail technical information for each wireless station. 31 The page below describes the detail connection information with each station. You can get all information needed right here. Backup/Restore Setting / Firmware Upgrade and Reboot In Management section, you can Backup/Restore Setting, Firmware Upgrade and Reboot the system in following pages. Backup the current settings to a file – Click on the “Backup” button, system will prompt you where to save the backup file. You can choose the directory to save your configuration file. 32 z Restore settings from a backup file – Here you can restore the configuration file from where you previous saved. Restore factory default setting – Be very carefully before restore system back to default since you will lose all current settings immediately. If you act the function, the ip address will restore the establishing value situation. 192.168.1.20 in the IP Address field and 255.255.255.0 in the Subnet Mask field, Firmware Upgrade – Enter the location of the firmware upgrade file in the file path field, or click the “Browse” button to find the firmware upgrade file. Then click on the “Upgrade” button, and follow the on-screen instructions. The whole firmware upgrade process will take around 60 seconds. Before upgrade, make sure you are using correct version. Double check with your technical support service if available. 33 z Reboot – Click on “Reboot” button to restart Access Point. 34 Wireless Configuration – WDS Mode (P2P & P2MP) WDS (Wireless Distribution System) operation as defined by the IEEE802.11 standard has been made available. In IEEE 802.11 terminology a "Distribution System" is system that Interconnects, so-called, Basic Service Sets (BSS). A BSS is best compared to a "Cell", driven by a single Access Point (one of those circles in the diagram below). So a "Distribution System" connects cells in order to build a premise wide network which allows users of mobile equipment to roam and stay connected to the available network resources. WDS is used for wirelessly connect Access Points, and in doing so extend a wired infrastructure to locations where cabling is not possible or inefficient to implement. (Be sure you understand the purpose of WDS mode before proceed configuration.) The WDS mode is coexisting with Access Point mode in this AP, therefore, you can support regular wireless stations and WDS link at the same time. In the “WDS Settings page”, click the “Enable WDS” check box and switch the “Mode” to “Enable”. Then you are able to fill in MAC Address of each WDS link. 35 Considerations before installation – Loop Prevention – Be careful to plan you WDS connections, prevent your wireless network topology to have loop. Once loop shows up, you network traffic will become unstable. Performance – The system can support up to 8 WDS links. But all links and wireless stations that operate at the same time will all share single radio bandwidth. (Ex. 11g have 54Mbps bandwidth) Latency – In the chain topology configuration, if the chain becomes very long, end-to-end latency issue may come in play. We suggest the WDS link topology planning should not exceed 2 hops in chain configuration. WDS Security – WDS now only supports limit wireless security protocol and will have full dependency with Access Point mode security settings. Here lists 4 different AP security settings below: No Security – Both AP and WDS traffic transmit without encryption WEP – Both AP and WDS traffic are encrypted by the same WEP key WPA-PSK – The AP work in WPA-PSK mode and WDS link is no security WPA – The AP work in WPA mode and WDS link is no security 36 Wireless Configuration – Wireless Client Mode AP can also work as an Ethernet client bridge to connect up to 16 Ethernet device into wireless network. In order to setup the AP to work in Ethernet bridge mode, you need to choose “Wireless Client” mode and click “Apply” at System Properties page. After need to reboot the AP to make sure the AP work in client mode. After the system reboot is done, you can see the page as below. Status page show the AP is now working in Wireless Client mode. 37 Connection Status z Connection – This column show current connection status. If AP already connect to an Access Point or station, here will show the MAC address of the associated Access Point or station. Otherwise, connection column will show “N/A” which means no connection to any Access Point or station. Network Type – Here indicates the Access Point works in AP mode or Client mode (Infrastructure mode / Ad Hoc mode) SSID – SSID column displays current SSID assigned to the AP Wireless Mode – Here show the Access Point current work in either 11b or 11g mode Current Channel – This column indicates the radio channel currently in use. Security - Here indicates AP security settings in client mode. Should be either “Disabled”, “WEP” or ‘WPA-PSK”. Link Quality – This column shows current link quality with AP by signal strength in 0 to 100 percentage scale. Wireless Network z Network Mode – You can set the wireless client into 2 different modes by clicking radio button. Wireless Client (Infrastructure) act as an AP client while Ad-hoc can support peer to peer network. Both Infrastructure and Ad-hoc can support up to 108M SuperG transmission. Wireless Mode - Default setting is “2.4GHz 54Mbps (802.11g)”. This will support all 802.11b/g clients connect to the AP. You can choose 38 z “2.4GHz 11Mbps (802.11b)” in wireless mode column if your environment only have 802.11b clients. The final selection “2.4GHz 108Mbps (802.11 SuperG)” supports high speed 108Mbps SuperG function. In order to support SuperG 108M transmission, all wireless clients will need to be Atheros® solution. SSID - The SSID is the unique name shared among all points in a wireless network. The SSID must be identical for all points in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any keyboard character. You can choose “Attach to any available SSID”; system will determine the Access Point currently available and establish connection with that Access Point. If you already understand your wireless environment well, you can type in the SSID in “Specify the static SSID” manually. At Wireless Network page you can find a “Site Survey” button as shown below. You can easily click on the “Site Survey” to find all wireless networks available in your current environment. The Site Survey page can help you identify all the APs currently working in your environment. Just easily click on the BSSID column, the system will join you to the SSID you specify. In the Site Survey page you can also see the details of all SSID currently available. 39 After you determine which AP (SSID) to join, you can click on the BSSID column your want to choose. The system will automatically join the SSID you specified after reboot. Wireless Security – WEP is a basic encryption method, which is not as secure as WPA. To use WEP as a client, you will need to input a transmit key and a level of WEP encryption exactly the same as the Access Point. Shared keys input type – Select HEX or ASCII depends on your preference Key table – You can input 4 different WEP encryption keys into the table and by choosing the radio button to decide which one is valid now. The AP supports 64, 128 and 152bit key length. The longer key we choose usually means the encryption is stronger. After all changes are made, be sure to click on “Apply” to make sure all changes are saved into system. 40 WPA-PSK stands for Wi-Fi Protected Access – Pre-Shared Key. WPA-PSK is design for home users who do not have RADIUS server in their network environment. WPA can provide better security level than WEP without difficult setting procedure. PassPhrase Key - Enter a WPA Shared Key of 8-63 characters. The Shared Key should be also applying the Access Point work in the same wireless network. Cipher Type - WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the type of algorithm, TKIP or AES. Remember to click on “Apply” to make sure all changes are made before leaving this page. 41 Ethernet Client List – In Ethernet Client List page, you can check all the details here including IP Address and MAC Address. Press “Refresh” if you add any new Ethernet client into network. The page will update latest status of current Ethernet network. 42 Wireless Configuration – Wireless Repeater Mode When set the Access Point to Repeater mode, the AP is able to talk with one remote access point within its range and retransmit its signal. In order to setup the AP to work in Ethernet bridge mode, you need to choose “Repeater” mode and click “Apply” at System Properties page. After need to reboot the AP to make sure the AP work in repeater mode. After enable the repeater mode, you can click on “Wireless Network” and choose “Site Survey” to pick one of the SSIDs you would like to retransmit its signal. (Please be awarded that while using the repeater mode, the throughput performance maybe nearly only half compare with access point mode. Because the repeater needs to communicate with original AP and also the clients associate to the repeater at the same time.) 43 After click on the “Site Survey” button, you can choose the Access Point you need to extend its range by clicking on “BSSID” column. Then “Apply” the change to make sure system working properly with new setting. After all the changes are made, you can check the “Connect Status” page to check current SSID and link quality / signal strength.

Network - A series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users. Node - A network junction or connection point, typically a computer or work station. Packet - A unit of data sent over a network. Passphrase - Used much like a password, a passphrase simplifies the WEP encryption process by automatically generating the WEP encryption keys for Linksys products. Port - The connection point on a computer or networking device used for plugging in cables or adapters. Roaming - The ability to take a wireless device from one access point's range to another without losing the connection. Router - A networking device that connects multiple networks together. RTS (Request To Send) - A networking method of coordinating large packets through the RTS Threshold setting. Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services. SNMP (Simple Network Management Protocol) - A widely used network monitoring and control protocol. Software - Instructions for the computer. A series of instructions that performs a particular task is called a "program". SOHO (Small Office/Home Office) - Market segment of professionals who work at home or in small offices. Spread Spectrum - Wideband radio frequency technique used for more reliable and secure data transmission. SSID (Service Set IDentifier) - Your wireless network's name. Static IP Address - A fixed address assigned to a computer or device that is connected to a 47 network. Subnet Mask - An address code that determines the size of the network. Switch - 1. A data switch that connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical circuit. TCP (Transmission Control Protocol) - A network protocol for transmitting data that requires acknowledgement from the recipient of data sent. TCP/IP (Transmission Control Protocol/Internet Protocol) - A set of instructions PCs use to communicate over a network. TKIP (Temporal Key Integrity Protocol) - a wireless encryption protocol that provides dynamic encryption keys for each packet transmitted. Topology - The physical layout of a network. Upgrade - To replace existing software or firmware with a newer version. WEP (Wired Equivalent Privacy) - An optional cryptographic confidentiality algorithm specified by IEEE 802.11 that may be used to provide data confidentiality that is subjectively equivalent to the confidentiality of a wired local area network (LAN) medium that does not employ cryptographic techniques to enhance privacy confidentiality. WPA (Wi-Fi Protected Access) - a wireless security protocol using TKIP (Temporal Key Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server. 48 Appendix B: Specification Standard support IEEE802.11b IEEE802.11g IEEE802.3 IEEE802.3u Interface Wireless IEEE802.11b/g One 10/100 RJ-45 port SDRAM 8Mbyte Flash 2Mbyte Max.
