  19. SIMULATION

    Ann, a local librarian, has had a previously used wireless access point donated to her. She has instructed you to configure this new wireless access point for her public library. Ann plans to allow anyone to connect to the access point without having to ask her for configuration information. Additionally, Ann knows that her neighbors have wireless networks and wants to ensure that her network has the least likelihood of interfering with the other networks. Ann has provided you with the following information.

    Wireless Name: Library
    New Router Password: Secure$1

    INSTRUCTIONS

    Instructions: Select the Public Library in the diagram to configure the wireless network. Once the wireless network tabs are configured, select the save button. When you have completed the simulation, please, select the Done button to submit.
    Configure Ann’s wireless library network using the network adapter window.
    If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
