Chapter 1: Initial Configuration The Access Point offers a user-friendly web-based management interface for the configuration of all the unit’s features. Any PC directly attached to the unit can access the management interface using a web browser, such as Internet Explorer (version 5.0 or above). The initial configuration steps can be made through the web browser interface using the Setup Wizard.
1 Initial Configuration The home page displays the Main Menu. There are two options available, you can configure the basic features of the access point using the Setup Wizard’s simple steps, or you can configure all features in detail using the Advanced Setup menu. Figure 1-2. Home Page Using the Setup Wizard There are only a few basic steps you need to set up the access point and provide a connection for your Wi-Fi phone and network access for other wireless stations.
1 Using the Setup Wizard 2. Operation Mode Setting – Select an operation mode according to how your divice will function. Figure 1-3. Setup Wizard - Network Setting (AP) There are three operation modes: • AP — Set the device as an Access Point. • Repeater — Set the device as a Wireless Repeater to relay messages between subnetworks that use different protocols or cable types. The Root AP MAC Address can be assigned manually or selected after click “Scan”. Figure 1-4.
1 Initial Configuration • Bridge — Set the device as a Wireless Bridge to connect two local-area networks (LANs), or two segments of the same LAN that use the same protocol. The Bridge Nodes need to be assigned manually by the user. Figure 1-5.
1 Using the Setup Wizard 3. Network Setting – Sets the access point’s IP address assignment method and configures the local Dynamic Host Configuration Prototcol (DHCP) server and Network Address Translation (NAT) settings. Figure 1-6. Setup Wizard - Network Setting There are three basic methods for configuring the access point’s IP address: • Dynamic IP — The IP address is assigned automatically from a home gateway router or other device that has a DHCP server feature.
1 Initial Configuration Figure 1-7. Setup Wizard - DHCP Server and NAT Settings DHCP Server/NAT Setting — This access point includes a DHCP server that can assign IP addresses to any wireless station or Wi-Fi phone requesting the service. Addresses are assigned from a common address pool configured on the access point. You can configure the address pool by specifying start and end IP addresses.
1 Using the Setup Wizard 4. Wireless VAP #1 Setting – Sets the wireless Service Set Identifier (SSID) and wireless security encryption key for the VAP#1 network. Note that it is recommended to restrict one VAP network for only Wi-Fi phones and let all other wireless stations use the other VAP network. Figure 1-8. Setup Wizard - Setting the VAP#1 SSID and Security Enter the SSID, or wireless network name, which all wireless stations must use to associate with the access point.

Chapter 2: System Configuration The access point’s basic settings can be configured using the Setup Wizard, as described in the previous chapter, “Initial Configuration.” However, for some installations, you may need to configure specific settings that are not available in the Setup Wizard. The Advanced Setup menu provides access to all the unit’s settings for complete control of the access point’s features. To access the Advanced Setup menus, follow these steps: 1.
2 System Configuration The Advanced Setup pages include the options in the table below. For details on configuration for each feature, see the corresponding page number. Table 2-1.
2 Information Information The system information pages display details on the current configuration and status of the access point, including associated wireless stations and event log messages. System The system information page displays basic system configuration settings, as well as the settings for each wireless interface. The displayed settings are for status information only and are not configurable on this page. Figure 2-2.
2 System Configuration • HTTP Server – The status of the web management server. • HTTP Server Port – The TCP port used by the web management server. • Version – The version number of the current access point software. Wireless Data #1/#2 SSID Configuration – The AP Wireless Configuration table displays the wireless interface settings listed below. • SSID – The service set identifier for this wireless group. • Channel – The radio channel through which the access point communicates with wireless clients.
Information 2 system” and “shared key.” Open-system authentication accepts any client attempting to connect to the access point without verifying its identity. The shared-key approach uses Wired Equivalent Privacy (WEP) to verify client identity by distributing a shared key to clients before attempting authentication. • Associated – Shows if the client has been successfully associated with the access point. Clients can associate with the access point only after authentication has completed.
2 System Configuration Event Log The Event Log page displays system messages generated during system operation. The logged messages can serve as a valuable tool for isolating access point and network problems. Figure 2-5. Event Log The Event Log page displays the last 128 messages logged in chronological order, from the newest to the oldest. Log messages saved in the access point’s memory are erased when the device is rebooted.
System Settings 2 System Settings The system settings pages allow you to change the management access password and restart the access point. Administration Management access to the access point is controlled through a single password. To protect access to the management interface, you need to configure an Administrator password as soon as possible. If the password is not configured, then anyone having access to the access point may be able to compromise access point and network security.
2 System Configuration Operation Mode The device can be set as an access point, a wireless repeater or a wireless bridge according to user’s need. Figure 2-7. Administration Password There are three operation modes: • AP — Set the device as an Access Point. • Repeater — Set the device as a Wireless Repeater to relay messages between subnetworks that use different protocols or cable types. The Root AP MAC Address can be assigned manually or selected after click “Scan”.
System Settings 2 The displayed items on this page can be described as follows: • Restore Factory Settings – Click the Restore button to reset the configuration settings for the access point to the factory defaults and reboot the system. Note that all user configured information will be lost. You will have to use the default IP address to re-gain management access to the access point. • Reboot Access Point – Click the Reboot button to reboot the system.
2 System Configuration Wireless VAP Settings The Wireless VAP #1 Setting and Wireless VAP #2 Setting pages include configuration options for radio signal characteristics and wireless security features on the access point. The following sections apply to both Wireless VAP #1 Setting and Wireless VAP #2 Setting pages. Note: it is recommended to restrict one VAP network for only Wi-Fi phones and let all other wireless stations use the other VAP network.
2 Wireless VAP Settings Channel Setting The access point uses one radio channel in the 2.4 GHz band to communicate with its clients. The radio channel may be set manually by the user or automatically by the system, which selects the channel with the least radio interference. Note: If you experience poor performance, you may be encountering interference from another wireless device. Try changing the channel, as this may eliminate interference and increase performance.
2 System Configuration Figure 2-11. WEP Wireless Security The displayed items on this page can be described as follows: • WEP Status – Enables the access point to use WEP shared keys. If enabled, you must configure at least one key for the VAP interface and all its clients. • Key Type – Select the preferred method of entering WEP encryption keys on the access point. - Hexadecimal: Enter keys as hexadecimal digits (0 to 9 and A to F). - Alphanumeric: Enter keys as alphanumeric characters.
2 Wireless VAP Settings Note: The computationally intensive operations of AES encryption requires hardware support on client devices. Before implementing AES in the network, be sure that wireless client hardware is AES or WPA2 compliant. Figure 2-12. WPA-PSK Wireless Security The displayed items on this page can be described as follows: • WPA-PSK Status – Enables WPA-PSK or WPA2-PSK security on the VAP interface. When enabled, WEP clients are not supported. (Default: Enabled).
2 System Configuration Network Settings The access point supports DHCP client, DHCP server and Network Address Translation (NAT). Point-to-Point Protocol over Ethernet (PPPoE) is also supported for users that have an IP address assigned automatically from an Internet service provider (ISP) through an ADSL modem. DHCP Client Configuring the access point with an IP address enables you to manage the access point from any PC in the attached network.
2 Network Settings • Subnet Mask – The mask that identifies the host address bits used for routing to specific subnets. • Default Gateway – The default gateway is the IP address of the router for the access point, which is used if the requested destination address is not on the local subnet. If you have management stations located on another subnet, type the IP address of the default gateway router in the text field provided. Otherwise, leave the address as all zeros (0.0.0.0).
2 System Configuration Figure 2-14. DHCP Server/NAT Settings The displayed items on this page can be described as follows: • DHCP Server/NAT Setting – Enables or disables the DHCP server and NAT on the access point. (Default: Enabled) • Start/End IP Address – Specifies the start/end IP address of a range that the DHCP server can assign to DHCP clients. You can specify a single address or an address range.
Network Settings 2 PPPoE Many Internet service providers (ISPs) use the Point-to-Point Protocol over Ethernet (PPPoE) to automatically assign an IP address to users with a DSL modem. The PPPoE page provides the settings needed for this service. Figure 2-15. PPPoE Settings The displayed items on this page can be described as follows: • PPPoE Setting — Enables the access point IP address to be assigned automatically from an Internet service provider (ISP) through an ADSL modem using PPPoE.
2 System Configuration Time and Log Simple Network Time Protocol (SNTP) allows the access point to set its internal clock based on periodic updates from a time server (SNTP or NTP). Maintaining an accurate time on the access point enables all system log messages to be stamped with the correct time and date. If the clock is not set, the access point only records the time from the factory default set at the last bootup.
2 Time and Log • Daylight Saving — The access point provides a way to automatically adjust the system clock for Daylight Savings Time changes. To use this feature you must define the month and date to begin and to end the change from standard time. During this period the system clock is set back by one hour.
2 System Configuration Updating Firmware You can upgrade new access point software from a local file on the management workstation, or from an FTP or TFTP server. After upgrading to new software, you must reboot the access point to implement the new code. Until a reboot occurs, the access point will continue to run the software it was using before the upgrade started.
Updating Firmware 2 Figure 2-18. Remote Server Upgrade The displayed items on this page can be described as follows: • Remote File — Specifies a software code file download from a remote FTP or TFTP server. • New firmware file — Specifies the name of the code file on the server. A path on the server can be specified using “/” in the destination file name, providing the path already exists. Other than to indicate a path, the file name must not contain any slashes (\ or /), the leading letter cannot be a pe

Glossary 10BASE-T IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3 or better UTP cable. 100BASE-TX IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 or better UTP cable. Access Point An internetworking device that seamlessly connects wired and wireless networks. Access points attached to a wired network, support the creation of multiple radio cells that enable roaming throughout a facility.
Glossary Dynamic Host Configuration Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Encryption Data passing between the access point and clients can use encryption to protect from interception and evesdropping.
Glossary Open System A security option which broadcasts a beacon signal including the access point’s configured SSID. Wireless clients can read the SSID from the beacon, and automatically reset their SSID to allow immediate connection to the nearest access point. Orthogonal Frequency Division Multiplexing (ODFM) OFDM/ allows multiple users to transmit in an allocated band by dividing the bandwidth into many narrow bandwidth carriers.
Glossary Wired Equivalent Privacy (WEP) WEP is based on the use of security keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded from network traffic. WPA Pre-shared Key (WPA-PSK) WPA-PSK can be used for small office networks with a limited number of users that may not need a high level of security. WPA-PSK provides a simple security implementation that uses just a pre-shared password for network access.
