  • Page 5: Introduction

    Introduction The Access Point is a wireless LAN bridge that can act as the connection point between the Ethernet CSMA/CD protocol and the wireless CSMA/CA protocol. 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.

  • Page 12: Setting The Ip Address

    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.
  • Page 13 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.
