It can also connect these wireless devices to wired network through the LAN interface The 802 11A G ACCESS POINT can also function in a Wireless Distribution System WDS mode Multiple 802 11A G ACCESS POINTS be configured to operate in the WDS mode to inter connect wired LAN segments that are attached to these 802 11A G ACCESS POINTS Since the 802 11g shares the same 2 4GHz radio band with the 802 11b technology it can inter operate with existing 802 11b up to 11Mbps devices Therefore You can reserve your existing investment in 802 11b client cards and migrate to the high speed 802 11g standard as your needs grow To address growing security concerns in a wireless LAN environment different levels of security can be enabled in the 802 11A G ACCESS POINT To disable SSID broadcast to restrict association to only those client stations that are already pre configured with the correct SSID B To enable WEP Wireless Encryption Protocol 64 128 or 152 bit encryption to protect the privacy of your data B Support of Access List Control to allow you to grant deny access to from specified wireless stations Provisioning of centralized authentication through Radius Server B WPA PSK Wi Fi Protected Access Pre Shared Key for home users to provide authentication data integrity and data privacy B WPA Wi Fi Protected Access works with a RADIUS server to provide stronger authentication as well as data integrity and p
4. POWER Follow these steps to install your 802 11A G ACCESS POINT Step 1 Connect a LAN hub to the LAN port on the 802 11A G ACCESS POINT using the supplied LAN cable Step 2 Connect the power adapter to an electrical outlet and the 802 11A G ACCESS POINT Note You can reset the Access Point s Settings to factory defaults by pushing a paperclip in the RESET hole Push and hold until the lights at the front of the Access Point are off 2 3 Configuration steps This section describes configuration required for the 802 11A G ACCESS POINT before it can work properly in your network First it is assumed that in your LAN environment a separate DHCP server will be available for assigning dynamic and often private IP addresses to requesting DHCP clients Additionally since you need to perform various configuration changes to the 802 11A G ACCESS POINT including the SSID Channel number the WEP key etc it is necessary to associate a fixed IP address with the 802 11A G ACCESS POINT which is why the 802 11A G ACCESS POINT will be shipped with a factory default private IP address of 192 168 1 1 and a network mask of 255 255 255 0 Therefore during the system installation time you need to build an isolated environment with the 802 11A G ACCESS POINT and PC and then perform the following steps Step 1 Manually change the IP address of the PC to become 192 168 1 3 Step 2 Connect the PC to the 802 11A G ACCESS POINT
5. 1 254 This IP address can be modified to either a different address in this same subnet or to address in a different subnet depending on the existing network settings if there is any uset s preferences 1 4 2 AUTOMATIC IP The 802 11A G ACCESS POINT can also be configured to obtain an IP address automatically from a DHCP server on the network This address is called dynamic because it 1s only dynamically assigned to the device which may change depends on the IP assignment policy used by the DHCP server on the network Since the IP address in this case may change from time to time this method 1s not recommended unless the user uses UPnP other management tools that do not depend on a fixed IP address Install the 802 11 A G Access Point This section describes the installation procedure for 802 11A G ACCESS POINT It starts with a summary of the content of the package you have purchased followed by steps of how to power up and connect the 802 11A G ACCESS POINT Finally this section explains how to configure a Windows PC to communicate with the 802 11A G ACCESS POINT 2 1 Whats in the box The 802 11A G ACCESS POINT package contains the following items B One 802 11A G ACCESS POINT B One 5V DC power adapter with a barrel connector B CD of the 802 11A G ACCESS POINT User Guide 2 2 Connect the cables The Back Panel of the 802 11A G ACCESS POINT appears as follows uy Le RESET
6. BSS iL The 802 11A G ACCESS POINT further provides bridging functions between the wireless network and the wired LAN network When multiple access points are connected to the same LAN segment stations can roam from one 802 11A G ACCESS POINT to another without losing their connections as long as they are using the same SSID See the diagram below Internet Router ET Backbone network AP 1 2 BSS1 BSS2 1 3 2 AS A POINT TO MULTI POINTS BRIDGE When configured to operate in the Wireless Distribution System WDS Mode the 802 11A G ACCESS POINT provides bridging functions between the LAN behind it and separates LANs behind other APs operating in the WDS mode The system will support up to eight APs in a WDS configuration Note that an 802 11A G ACCESS POINT runs in the WDS mode can also support wireless stations simultaneously See the diagram below Wireless Distribution system 1 4 Set up the device The 802 11A G ACCESS POINT be managed remotely by a PC through either the wired or wireless network To do this the 802 11A G ACCESS POINT must first be assigned an IP address which can be done using one of the following two methods 1 4 1 STATIC IP The default address of the LAN interface of an 802 11A G ACCESS POINT is a private IP address of 192 168 1 1 and network mask of 255 255 255 0 This means IP addresses of other devices on the LAN should be in the range of 192 168 1 2 to 192 168
