The Access Point can be easily integrated into your existing wireless network. In large installations, the roaming functionality provided by multiple Access Points allows wireless users to move freely throughout the facility while maintaining seamless, uninterrupted access to the network. This document describes the steps required for the initial IP address assign and AP configuration. The description includes the implementation of the above steps. 1.1 Installation Requirements Before you begin installation, make sure that you have the following items: · The Access Point · The AC to DC power adapter · The Documentation CD You will also need: · A computer that is connected to the same network as the Access Point. 1.2 System Requirements · Desktop or laptop PC configuration through Ethernet: · Operating System: MS Windows 98 / ME / 2000 / XP. 5 2. Wireless LAN basics Wireless LAN network defined by IEEE 802.11b standard committee could be configured as: · Ad Hoc wireless LAN, or · Infrastructure wireless LAN. Ad Hoc network is a group of notebooks with wireless LAN PC card called a BSS (Basic Service Set). These notebooks use their wireless LAN PC cards to communicate with each other, and notebooks cannot connect to the Internet. STA 2 STA 1 STA 3 Figure 2-1 Ad Hoc wireless network The most obvious differentiation between Infrastructure wireless network and Ad Hoc wireless network is that the notebooks in Infrastructure wireless network can make use of the resource in the Internet through Access Point. Access Point STA 1 Internet STA 3 STA 2 Figure 2-2 Infrastructure wireless network To set up your notebook's network as the type of "Ad Hoc" or "Infrastructure" wireless network depends completely on your requirement. Generally, if your network environment has an Access Point, we recommend that you set it as "Infrastructure" to connect to the Internet. 6 3. Installation This section describes the procedures for installing the Wireless LAN Bridge Access Point under Windows 98 SE operating system. Before You Start Before setting up your Access Point, ask your network system administrator for the following information: · · · · · · Your IP address, gateway address, and subnet mask if you're not using a DHCP server. The MAC address from the label on the bottom of the Access Point. Your Wireless Client Name Your Wireless SSID Your computer's unique client name and workgroup name For your network account, your user name and password. Every computer on a network is identified by a unique network address. There are two methods of assigning network addresses to computer on a TCP/IP network: · · Static IP addressing Dynamic IP addressing (DHCP) In networks with static IP addressing, the network administrator manually assigns an IP address to each computer. Once a static IP address is assigned, a computer uses the same IP address every time it reboots and logs on to the network. You may manually change the IP address in the Network Properties dialog box. Networks using static IP addresses are easy to set up and do not require additional network management software. In networks with dynamic IP addressing, a DHCP server in the network dynamically assigns IP addresses to all clients every time they log on to the network. Network using dynamic IP addresses require setting up and running a DHCP Server or installing the Wingate software package. 7 3.1 Install the SNMP Manager application Under Windows 98 SE Step 1 Insert the given documentation CD and then double click the MY Computer icon on your desktop. In my computer window, double click the CD Drive icon. Choose WLAN Access Point folder and double click Setup.exe to execute. It opens the welcome dialog box as shown next page then click Next. 8 Step 2 Software License Agreement, click Yes to accept. Step 3 Click Next to install to this folder. 9 Step 4 Select the type of setup you prefer, then click Next. Step 5 Setup will add program icons to the Program Folder listed below. You may type a new folder name, or select one from the Existing Folders list. Click Next to continue. 10 Step 6 Starting Set up Step 7 Click Finish to complete Setup. 11 3.2 Setting the IP Address Each station or device on your network must have a unique IP address. Following these steps to setting the IP address: Step 1 Connect an Ethernet station and the Access Point on the same subnet. The simplest way to accomplish is to connect the Access Point and the Ethernet station to the same hub. You need to check if the station IP address and the Sub-net mask are configured properly. Also the new IP address for the Access Point must correspond to the Subnet mask. Step 2 In my computer window, double click the CD Drive icon. Choose WLAN Access Point folder then double click to execute IPConfig.exe. Then IPConfig screen displays as shown. 12 Step 3 Type the "Access Point MAC Address" from the label on the bottom of the Access Point, type the "Config IP" address from your system administrator, and then click "OK". Step 3 Open a MS-DOS Prompt window and type ping followed by the IP address used in the IP Config. The IP address is assigned to the Access Point . The Access Point's replies to the ping confirm that the IP address was assigned correctly. Step 4 If you get a ping reply, then the IP address has been temporarily set. In order to set it permanently you need to run SNMP Manager without powering off the Access Point. 13 3.3 Using the SNMP Manager On the Start Menu, choose Start->Programs->SNMP Manager. 14 File menu When the application opens, under the File Menu there are the following submenus: Connect to AP Using this submenu you can directly connect with the Bridge Access Point by typing its IP Address in the panel which appears and at the Community field, type the appropriate password (The default password is "public"). Additionally you have to select the User or Administrator Authority in the Authority combo-box. User Authority allow you only to view and not to set or save changes to the Access Point Configuration, while Administrator Authority allow you to either view or set changes to the Access Point Configuration. Then press OK. If your network has a DHCP server IP Address can be automatically assigned to the Access Point. 15 Find Access Point This submenu allows you to find and connect with an Access Point without the necessity of knowing its IP Address. Choose this submenu in order to find the Access Points available for connection. Select one of the available Access Points and press "Connect", then appears indicating the IP Address of the selected Access Point and prompting you to select Authority and to write the appropriate password at the community field. Then press "OK". In case of a successful connection to the Access Point, the following window appears press "OK" 16 When the connection has been successfully established, you get a message in the left bottom corner indicating, "Get Configuration done" and on the right bottom corner the "IP Address" of the connected Access Point. File menu The file menu contains the following enabled submenus Close Connection AP Terminates the connection with the Access Point. You can find and associate with another access point by selecting the "Find Access Point" after close the connection. Download changes When all the desired values of the parameters have been set you are able to download the changes (save the changes) to the Access Point by selecting this submenu. Refresh After changing the access point setting, you can update your current display by clicking the "Fresh" function. 17 Options Defines the polling interval according to which the SNMP Manager polls the Access Point in order to update the statistics and the Associated Stations List. 18 Setup menu As soon as the connection has been established, you are able to start viewing or setting the Access Point parameters. Under the "Setup" menu, there are the following submenus. Bridge Under the "Bridge" submenu, there are two options: IP configuration By choosing this option the window of appears. "IP Address" and "IP Mask" can be modified through "IP Configuration", if DHCP client is not enabled. If DHCP client is enabled the IP Address field displays IP Address that was dynamically assigned to the AP by the network DHCP server and the IP Mask field displays IP Mask utilized by the network DHCP server. Additional you have to select the Primary Port which is the interface that determines the DHCP server. If changes are made, you need to "Download Changes" under the "File" menu in order to save them. Bridge IP Configuration Parameters MAC Address: Unique 48-bit, hard-coded Media Access Control address known as the station identifier. IP address: Network-assigned Internet Protocol address of the Access Point. IP Mask: Four sets of three digits that divides a network into subnet works. 19 Filtering If the IP Routing is enabled only the IP protocol packets will pass through the WLAN and any other protocol filtered out. 20 Wireless LAN Under this submenu there are the following three options available. Privacy options By choosing this option you must define the encryption key values of your choice.
