1 Introduction 1.1 Overview The Madge advanced Smart W ireless Access Po int (advanced AP) enables IEEE 802.11b client computers to access the resources on an Ethernet network.
Hardware Watchdog Timer. If the AP fir m ware enters an invalid state, the hardware watchdog timer will detect this situation and res tart the advanced AP. According ly, the advanced AP can recover from certain error situations. 2 First-Time Installation and Configuration 2.
2.3 Preparing for Configuration For the user (or administrator) to configure an ad vanced AP, a managing computer with a Web browser is needed. For first-time configuration of an advanced AP, an Ethernet netw ork interface card (NIC) should have been installed in the mana ging computer.
2.4 Configuring the Advanced AP After the IP addressing issue is resolved, launch a Web browser on the managing computer. Then, go to “ http://192.168.0.1 ” to access the Web-based Network Manager start page. TIP: For maintenance configuration of an advanced AP, the advanced AP can be reached by its host name using a Web browser.

2.4.3 Step 2: Configure IEEE 802.11 Settings Fig. 6. IEEE 802.11b communication settings. Go to the IEEE 802.11, Communication section to configure IEEE 802.11b-related communication settings, including Regulatory Domain , Channel Number , and Network Name (SSID) .
On the start page, you can review all the settings you have made . Changes are high lighted in red . If they are OK, click Restart to restart the advanced AP for the new settings to take effect. NOTE: About 7 seconds are needed for the advanced AP to complete its restart process.
1. Launch the configuration/monitoring utility prov ided by the vendor of the installed WLAN NIC. 2. Check if the client computer is associated to an access point, and the access point is the advanced AP. If the check fails, see Appendix B-1, “Wirel ess Settings Problems” for troubleshooting.
3 Using the Web-Based Network Manager This section explains each management pa ge of the Web-based Network Manager. 3.1 Overview Fig. 8. The Start page.

3.2 General Operations 3.2.1 Changing Password Fig. 11. Password. On this page, the user could cha nge the password for the right to modify the configuration of the advanced AP. The new password must be typed twice for confirmation. 3.2.2 Upgrading Firmware Fig.
Fig. 13. TFTP Server. TIP: It's more convenient to use the Firmware Upgr ade Wizard of Wireless Ne twork Manager to upgrade the firmware of an advanced AP. See section 4. NOTE: After the dialog box of the TFTP server program appears, be sure to specify the working folder within which the downloade d firmware files reside.
The IP address of the AP can be manually set or au tomatically assign ed by a DHC P server on the LAN. If you are manually setting the IP Address , Subnet Mask , and Default Gateway settings, set them appropriately, so that they comply with your LAN environment.
802.1x EAP-MD5. The IEEE 802.1x functionality is enabled and the username/password-based EAP-MD5 authentication is used. No data encryption. 802.1x EAP-MD5 + 64-bit WEP. The IEEE 802.1x functionality is enabled and the username/password-based EAP-MD5 authentication is used.
The IEEE 802.1x functionality of the a dvanced AP is controlled by the security mode (see Section 3.4.2). The advanced AP supports two authentication mechan ism s—EAP-MD5 (Message Digest version 5) and EAP-TLS (Transport Layer Security). If EAP-MD5 is used, the user has to give his or her user name and password for authentication.
3.5 Configuring Advanced Settings 3.5.1 Management 3.5.1.1 SNMP Fig. 19. SNMP settings. The AP can be managed by SNMP (Simple Network Ma nagem ent Protocol), and the SNMP management functionality can be disabled. The us er can specif y the name (used as a password ) of the read-only and read-write community.
2. If AutoPlay is enabled then the “Accept W arranty Dialog” should appear (if not, it can be run from D:Setup.exe where D: is the drive letter of your CD -ROM). Read the agreement and click Accept if you agree to the terms of the W arrant y. The following dialog will appear: Fig.

For a wireless client computer to communicate with a correspondent ho st on the Internet by the host’s domain name (e.g. http://www.madge.com ), it first sends a DNS request to a DNS server on the Internet. The DNS request travels first to the advanced AP, the a dvanced AP then relays this r equest to the default gateway of the client computer.
