7Wireless LAN Networking This section provides background information on wireless LAN networking technology. Consult the “Glossary” for definitions of the terminology used in this section. THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR. Transmission Rate (Transfer Rate) The WAP-372U provides various transmission (data) rate options for you to select. In most networking scenarios, the factory default Best (Auto) setting proves the most efficient. This setting allows your WAP-372U to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, the WAP-372U automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the WAP-372U gradually increases the transmission (data) rate again until it reaches the highest available transmission rate. Types of Wireless Networks Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infra-structure mode, wireless devices communicate to a wired LAN via access points. Each access point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set (ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer mode), wireless devices communicate with each other directly and do not use an access point. This is an Independent BSS (IBSS). To connect to a wired network within a coverage area using access points, set the WAP-372U operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use Ad-hoc (IBSS) mode. AD-HOC (IBSS) NETWORK Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS). To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and channel for each station.
8
9 When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS). In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network. In an ESS environment, users are able to move from one access point to another without losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WAP-372U automatically switches to the channel used in BSS (2).

11 Introduction The WAP-372U is an 802.11n (draft) high-performance, wireless AP that supports high-speed wireless networking at home, at work or in public places. Unlike most APs, the WAP-372U provides data transfers at up to 300 Mbps when used with other 11n (draft) products. This AP is backwards compatible with 802.11b/g products. This means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 802.11g’s speed when you mix 802.11n (draft) and 802.11g devices, but you will not lose the ability to communicate when you incorporate the 802.11n (draft) into your 802.11g network. You may choose to slowly change your network by gradually replacing the 802.11g devices with 802.11n (draft) devices. Features Ø Supports IEEE 802.11n (draft) & 11b/g 2.4GHz wireless Local Area Network (WLAN) application Ø 2.412 to 2.484GHz frequency band operation Ø Compliant with IEEE 802.3 & 3u standards Ø Support OFDM and CCK modulation Ø Data rates of 1,2.5.5,6,9,12,18,24,36,48,54Mbps and 802.11n (draft) offering up to 300Mbps.

Page 14 The WAP-372U 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: 1 Keep the number of walls and ceilings between the WAP-372U and other network devices to a minimum - each wall or ceiling can reduce your wireless product’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. 2 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 ceiling (instead of at an angle) for better reception. 3 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. 4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme RF noise. Getting Started For a typical wireless setup at home, please do the following: 1. Plug the power adapter to outlay, and connect the power jack to the WAP-372U. 2. Connect the Ethernet LAN port of the WAP-372U to your PC. 3. Open your web browser, and type http://192.168.1.100 to login WAP-372U. 4. When the authentication window is popped up, type the admin for the username, and leave the password as blank, then type enter to login the web page of the WAP-372U. 5. Configure the desired wireless setting. 6. Connect the Ethernet port of the WAP-372U to your router.
Page 15 Using the Configuration Menu Whenever you want to configure your WAP-372U, you can access the Configuration Menu by opening the Web-browser and typing in the IP Address of the WAP-372U. The WAP-372U’s default IP Address is http://192.168.1.100. Ø Open the Web browser. Ø Type in the IP Address of the AP (http://192.168.1.100). If you have changed the default IP Address assigned to the WAP-372U, make sure to enter the correct IP Address. Ø Type admin in the User Name field. Ø Leave the Password blank. Ø Click Login In.
Page 16 Basic The Basic tab provides the following configuration options: Wizard, Wireless and Network Settings. Basic_Wizard Wireless Setup Wizard If you are new to networking and have never configured an access point before, click on Launch Wireless Setup Wizard and the wizard will guide you through a few simple steps to get your network up and running. Basic_Wireless
Page 17 The wireless section is used to configure the wireless settings for your Access Point. Note that changes made in this section may also need to be duplicated on wireless clients that you want to connect to your wireless network. To protect your privacy, use the wireless security mode to configure the wireless security features. This device supports three wireless security modes including: WEP, WPA-Personal, and WPA-Enterprise. WEP is the original wireless encryption standard. WPA provides a higher level of security. WPA-Personal does not require an authentication server. The WPA-Enterprise option does require a RADIUS authentication server. Wireless Radio This status indication shows you the wireless radio is on or off. Wireless Network Name
Page 18 When you are browsing for available wireless networks, this is the name that will appear in the list (unless Visibility Status is set to Invisible, see below). This name is also referred to as the SSID. For security purposes, it is highly recommended to change from the pre-configured network name. Enable Auto Channel Scan If you select this option, the Access Point automatically finds the channel with least interference and uses that channel for wireless networking. If you disable this option, the Access Point uses the channel that you specify with the following Wireless Channel option. Wireless Channel A wireless network uses specific channels in the wireless spectrum to handle communication between clients. Some channels in your area may have interference from other electronic devices. Choose the clearest channel to help optimize the performance and coverage of your wireless network. 802.11 Mode If all of the wireless devices you want to connect with this Access Point can connect in the same transmission mode, you can improve performance slightly by choosing the appropriate "Only" mode. If you have some devices that use a different transmission mode, choose the appropriate "Mixed" mode. Channel Width The "Auto 20/40 MHz" option is usually best. The other options are available for special circumstances. Transmission Rate By default the fastest possible transmission rate will be selected. You have the option of selecting the speed if necessary. Visibility Status The Invisible option allows you to hide your wireless network. When this option is set to Visible, your wireless network name is broadcast to anyone within the range of your signal. If you're not using encryption then they could connect to your network. When Invisible mode is enabled, you must enter the Wireless Network Name (SSID) on the client manually to connect to the network. Security Mode Unless one of these encryption modes is selected, wireless transmissions to and from your wireless network can be easily intercepted and interpreted by unauthorized users. WEP A method of encrypting data for wireless communication intended to provide the same level of privacy as a wired network. WEP is not as secure as WPA encryption. To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using
Page 19 characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange - alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can change keys easily. A default key is selected for use on the network. Example: 64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters for 64-bit encryption.) 128-bit hexadecimal keys are exactly 26 characters in length. (456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit encryption.) 64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5 characters for 64-bit encryption.) 128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string of 13 characters for 128-bit encryption.) Note that, if you enter fewer characters in the WEP key than required, the remainder of the key is automatically padded with zeros. WPA-Personal and WPA-Enterprise Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security standards published by the Wi-Fi Alliance. The WPA Mode further refines the variant that the Access Point should employ. WPA Mode: WPA is the older standard; select this option if the clients that will be used with the Access Point only support the older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security standard. With the "WPA or WPA2" option, the Access Point tries WPA2 first, but falls back to WPA if the client only supports WPA. The strongest cipher that the client supports will be used. With the "WPA2 Only" option, the Access Point associates only with clients that also support WPA2 security. The AES cipher will be used across the wireless network to ensure best security. Group Key Update Interval: The amount of time before the group key used for broadcast and multicast data is changed. WPA-Personal This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK). Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in ASCII (American Standard Code for Information Interchange) format at both ends of the wireless connection. It cannot be shorter than eight characters, although for proper security it needs to be of ample length and should not be a commonly known phrase. This phrase is used to generate session keys that are unique for each wireless client. Example: Wireless Networking technology enables ubiquitous communication WPA-Enterprise This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should have established the necessary credentials before attempting to authenticate to
Page 20 the Server through this Gateway. Furthermore, it may be necessary to configure the RADIUS Server to allow this Gateway to authenticate users. Authentication Timeout: Amount of time before a client will be required to re-authenticate. RADIUS Server IP Address: The IP address of the authentication server. RADIUS Server Port: The port number used to connect to the authentication server. RADIUS Server Shared Secret: A pass-phrase that must match with the authentication server. MAC Address Authentication: If this is selected, the user must connect from the same computer whenever logging into the wireless network. Advanced: Optional Backup RADIUS Server This option enables configuration of an optional second RADIUS server. A second RADIUS server can be used as backup for the primary RADIUS server. The second RADIUS server is consulted only when the primary server is not available or not responding. The fields Second RADIUS Server IP Address, RADIUS Server Port, Second RADIUS server Shared Secret, Second MAC Address Authentication provide the corresponding parameters for the second RADIUS Server. Basic_Network Settings
Page 21 Access Point Settings These are the settings of the LAN (Local Area Network) interface for the Access Point. The Access Point's local network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this section. The IP address is also used to access this Web-based management interface. Get LAN IP From Choose "DHCP (Dynamic)" if your router supports DHCP and you want the router to assign an IP address to the AP. In this case, you do not need to fill in the following fields. Choose "Static IP (Manual)" if your router does not support DHCP or if for any other reason you need to assign a fixed address to the AP. In this case, you must also configure the following fields. Note that you cannot choose "DHCP (Dynamic)" if you have enabled the "DHCP Server" option on the DHCP page; the AP cannot be both a DHCP client and a DHCP server.
Page 22 IP Address The IP address of the AP on the local area network. Assign any unused IP address in the range of IP addresses available for the LAN. For example, 192.168.1.100. Subnet Mask The subnet mask of the local area network. Gateway The IP address of the router on the local area network. Local Domain Name This entry is optional. Enter a domain name for the local network. The AP's DHCP server will give this domain name to the computers on the wireless LAN. So, for example, if you enter mynetwork.net here, and you have a wireless laptop with a name of chris, that laptop will be known as chris.mynetwork.net. Note, however, if the AP's settings specify "DHCP (Dynamic)" Address, and the router's DHCP server assigns a domain name to the AP, that domain name will override any name you enter here. DHCP Server Settings DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you configure the built-in DHCP Server to assign IP addresses to the computers and other devices on your local area network (LAN). Enable DHCP Server In most situations, the router provides DHCP services, and you can leave this option disabled. However, if for any reason the router does not provide DHCP services, enable this option. The AP's DHCP Server will then manage the IP addresses and other network configuration information for wireless clients associated with the AP. The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to "DHCP" or "Obtain an IP address automatically". When you set Enable DHCP Server, the following options are displayed. DHCP IP Address Range These two IP values (from and to) define a range of IP addresses that the DHCP Server uses when assigning addresses to computers and devices on your Local Area Network. Any addresses that are outside of this range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices or devices that cannot use DHCP to obtain network address details automatically. It is possible for a computer or device that is manually configured to have an address that does reside within this range. In this case the address should be reserved, so that the DHCP Server knows that this specific address can only be used by a specific computer or device. Your Access Point, by default, has a static IP address of 192.168.1.100. This means that addresses 192.168.1.101 to 192.168.1.254 can be made available for allocation by the DHCP Server. Example:
Page 23 Your Access Point uses 192.168.1.1 for the IP address. You've assigned a computer that you want to designate as a Web server with a static IP address of 192.168.1.101. You've assigned another computer that you want to designate as an FTP server with a static IP address of 192.168.1.102. Therefore the starting IP address for your DHCP IP address range needs to be 192.168.1.103 or greater. Example: Suppose you configure the DHCP Server to manage addresses From 192.168.1.101 To 192.168.1.199. This means that 192.168.1.1 to 192.168.1.99 and 192.168.1.200 to 192.168.1.254 are NOT managed by the DHCP Server. Computers or devices that use addresses from these ranges are to be manually configured. Suppose you have a web server computer that has a manually configured address of 192.168.1.101. Because this falls within the "managed range" be sure to create a reservation for this address and match it to the relevant computer. DHCP Lease Time The amount of time that a computer may have an IP address before it is required to renew the lease. The lease functions just as a lease on an apartment would. The initial lease designates the amount of time before the lease expires. If the tenant wishes to retain the address when the lease is expired then a new lease is established. If the lease expires and the address is no longer needed than another tenant may use the address. Always Broadcast If all the computers on the LAN successfully obtain their IP addresses from the Access Point's DHCP server as expected, this option can remain disabled. However, if one of the computers on the LAN fails to obtain an IP address from the Access Point's DHCP server, it may have an old DHCP client that incorrectly turns off the broadcast flag of DHCP packets. Enabling this option will cause the Access Point to always broadcast its responses to all clients, thereby working around the problem, at the cost of increased broadcast traffic on the LAN. Add/Edit DHCP Reservation This option lets you reserve IP addresses, and assign the same IP address to the network device with the specified MAC address any time it requests an IP address. This is almost the same as when a device has a static IP address except that the device must still request an IP address from the Access Point. The Access Point will provide the device the same IP address every time. DHCP Reservations are helpful for server computers on the local network that are hosting applications such as Web and FTP. Servers on your network should either use a static IP address or use this option. Computer Name You can assign a name for each computer that is given a reserved IP address. This may help you keep track of which computers are assigned this way. Example: Game Server. IP Address: The LAN address that you want to reserve. MAC Address To input the MAC address of your system, enter it in manually or connect to the Access Point's Web-Management interface from the system and click the Copy Your PC's MAC Address button.
Page 24 A MAC address is usually located on a sticker on the bottom of a network device. The MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your network device is a computer and the network card is already located inside the computer, you can connect to the Access Point from the computer and click the Copy Your PC's MAC Address button to enter the MAC address. As an alternative, you can locate a MAC address in a specific operating system by following the steps below: Windows 98 Windows Me Go to the Start menu, select Run, type in winipcfg, and hit Enter. A popup window will be displayed. Select the appropriate adapter from the pull-down menu and you will see the Adapter Address. This is the MAC address of the device. Windows 2000 Windows XP Go to your Start menu, select Programs, select Accessories, and select Command Prompt. At the command prompt type ipconfig /all and hit Enter. The physical address displayed for the adapter connecting to the Access Point is the MAC address. Mac OS X Go to the Apple Menu, select System Preferences, select Network, and select the Ethernet Adapter connecting to the Access Point. Select the Ethernet button and the Ethernet ID will be listed. This is the same as the MAC address. DHCP Reservations List This shows clients that you have specified to have reserved DHCP addresses. An entry can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit DHCP Reservation" section is activated for editing. Number of Dynamic DHCP Clients In this section you can see what LAN devices are currently leasing IP addresses. Revoke The Revoke option is available for the situation in which the lease table becomes full or nearly full, you need to recover space in the table for new entries, and you know that some of the currently allocated leases are no longer needed. Clicking Revoke cancels the lease for a specific LAN device and frees an entry in the lease table. Do this only if the device no longer needs the leased IP address, because, for example, it has been removed from the network. Reserve The Reserve option converts this dynamic IP allocation into a DHCP Reservation and adds the corresponding entry to the DHCP Reservations List.
Page 25 Advanced The Advanced tab provides the following configuration options: MAC Address Filter and Advanced Network. Advanced_MAC Address Filter The MAC address filter section can be used to filter network access by machines based on the unique MAC addresses of their network adapter(s). It is most useful to prevent unauthorized wireless devices from connecting to your network. A MAC address is a unique ID assigned by the manufacturer of the network adapter. Enable MAC Address Filter When this is enabled, computers are granted or denied network access depending on the mode of the filter. Note: Misconfiguration of this feature can prevent any machine from accessing the network. In such a situation, you can regain access by activating the factory defaults button on the Access Point itself. Filter Settings
Page 26 Mode When "only allow listed machines" is selected, only computers with MAC addresses listed in the MAC Address List are granted network access. When "only deny listed machines" is selected, any computer with a MAC address listed in the MAC Address List is refused access to the network. Filter Wireless Clients When this is selected, the MAC address filters will be applied to wireless network clients. Filter Wired Clients When this is selected, the MAC address filters will be applied to wired network clients. Add/Edit MAC Address In this section, you can add entries to the MAC Address List below, or edit existing entries. Enable MAC address entries can be activated or deactivated with this checkbox. MAC Address Enter the MAC address of the desired computer or connect to the Access Point from the desired computer and click the Copy Your PC's MAC Address button. Save Saves the new or edited MAC Address entry in the following list. When finished updating the MAC Address List, you must still click the Save Settings button at the top of the page to make the changes effective and permanent. MAC Address List The section lists the current MAC Address filters. A MAC Address entry can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit MAC Address" section is activated for editing. Advanced_Advanced Wireless
Page 27 Beacon Period Beacons are packets sent by a wireless Access Point to synchronize wireless devices. Specify a Beacon Period value between 20 and 1000. The default value is set to 100 milliseconds. RTS Threshold This setting should remain at its default value of 2346. If you encounter inconsistent data flow, only minor modifications to the value are recommended. Fragmentation Threshold This setting should remain at its default value of 2346. Setting the Fragmentation value too low may result in poor performance. DTIM Interval A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the wireless Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255.
Page 28 WMM Enable Enabling WMM can help control latency and jitter when transmitting multimedia content over a wireless connection. Short GI Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for your installation. WDS Enable When WDS is enabled, this access point functions as a wireless repeater and is able to wirelessly communicate with other APs via WDS links. Note that WDS is incompatible with WPA -- both features cannot be used at the same time. A WDS link is bidirectional; so this AP must know the MAC Address (creates the WDS link) of the other AP, and the other AP must have a WDS link back to this AP. Make sure the APs are configured with same channel number. WDS AP MAC Address Specifies one-half of the WDS link. The other AP must also have the MAC address of this AP to create the WDS link back to this AP. Enter a MAC address for each of the other APs that you want to connect with WDS.
Page 29 Tools The Tools tab provides the following configuration options: Admin, Time, System and Firmware. Tool_Admin The Admin option is used to set a password for access to the Web-based management. By default there is no password configured. It is highly recommended that you create a password to keep your new Access Point secure. Admin Password
Page 30 Enter a password for the user "admin", who will have full access to the Web-based management interface. User Password Enter a password for the user "user", who will have read-only access to the Web-based management interface. System Name The name of the Access Point can be changed here.
Page 31 Tool_Time The Time Configuration option allows you to configure, update, and maintain the correct time on the Access Point's internal system clock. From this section you can set the time zone that you are in and set the Time Server. Daylight saving can also be configured to automatically adjust the time when needed. Time Configuration Current Access Point Time Displays the time currently maintained by the Access Point. If this is not correct, use the following options to configure the time correctly. Time Zone
Page 32 Select your local time zone from pull down menu. Enable Daylight Saving Check this option if your location observes daylight saving time. Daylight Saving Offset Select the time offset, if your location observes daylight saving time. DST Start and DST End Select the starting and ending times for the change to and from daylight saving time. For example, suppose for DST Start you select Month="Oct", Week="3rd", Day="Sun" and Time="2am". This is the same as saying: "Daylight saving starts on the third Sunday of October at 2:00 AM." Set the Date and Time Manually If you do not have the NTP Server option in effect, you can either manually set the time for your Access Point here, or you can click the Copy Your Computer's Time Settings button to copy the time from the computer you are using. (Make sure that computer's time is set correctly.) Note: If the Access Point loses power for any reason, it cannot keep its clock running, and will not have the correct time when it is started again. To maintain correct time for schedules and logs, either you must enter the correct time after you restart the Access Point, or you must enable the NTP Server option.
Page 33 Tool_System This section allows you to manage the Access Point's configuration settings, reboot the Access Point, and restore the Access Point to the factory default settings. Restoring the unit to the factory default settings will erase all settings, including any rules that you've created.

Page 34 Tool_Firmware The Firmware Upgrade section can be used to update to the latest firmware code to improve functionality and performance. To upgrade the firmware, follow these steps: 1. Click the Browse button to locate the upgrade file on your computer. 2. Once you have found the file to be used, click the Upload button below to start the firmware upgrade process. This can take a minute or more. 3. Wait for the Access Point to reboot. This can take another minute or more. 4. Confirm updated firmware revision on status page.
Page 35 Firmware Information Here are displayed the version numbers of the firmware currently installed in your Access Point and the most recent upgrade that is available. Firmware Upgrade Note: Firmware upgrade cannot be performed from a wireless device. To perform an upgrade, ensure that you are using a PC that is connected to the Access Point by wire. Note: Some firmware upgrades reset the configuration options to the factory defaults. Before performing an upgrade, be sure to save the current configuration from the Tools -> Admin screen. Upload Once you have a firmware update on your computer, use this option to browse for the file and then upload the information into the Access Point.
Page 36 Status The Status tab provides the following configuration options: Device Info, Wireless and Statistics. Status_Device Info All of your network connection details are displayed on the Device Info page. The firmware version is also displayed here. LAN Computers
Page 37 This area of the screen continually updates to show all DHCP enabled computers and devices connected to the LAN side of your Access Point. The detection "range" is limited to the address range as configured in DHCP Server. Computers that have an address outside of this range will not show. If the DHCP Client (i.e. a computer configured to "Automatically obtain an address") supplies a Host Name then that will also be shown. Any computer or device that has a static IP address that lies within the detection "range" may show, however its host name will not. Status_Wireless The wireless section allows you to view the wireless clients that are connected to your wireless Access Point. MAC Address The Ethernet ID (MAC address) of the wireless client. IP Address The LAN-side IP address of the client. Mode
Page 38 The transmission standard being used by the client. Values are 802.11b, 802.11g, or 802.11ng respectively. Rate The actual transmission rate of the client in megabits per second. Signal This is a relative measure of signal quality. The value is expressed as a percentage of theoretical best quality. Signal quality can be reduced by distance, by interference from other radio-frequency sources (such as cordless telephones or neighboring wireless networks), and by obstacles between the Access Point and the wireless device. Status_Statistics The Statistics page displays all of the LAN and Wireless packet transmit and receive statistics.
Page 39 Sent The number of packets sent from the Access Point. Received The number of packets received by the Access Point. TX Packets Dropped The number of packets that were dropped while being sent, due to errors, collisions, or Access Point resource limitations. RX Packets Dropped The number of packets that were dropped while being received, due to errors, collisions, or Access Point resource limitations. Collisions The number of packets that were dropped due to Ethernet collisions (two or more devices attempting to use an Ethernet circuit at the same time). Errors The number of transmission failures that cause loss of a packet. A noisy radio-frequency environment can cause a high error rate on the wireless LAN.
