Answers Note: You must prepare a wireless router for this activity by modifying a MAC address in the MAC address filter table and then saving the incorrect configuration. The instructions for modifying a MAC address in the filter table are below.
- Ensure that all computers are able to connect to the wireless router with basic security and with MAC address filtering configured.
- Connect an Ethernet cable from an Ethernet port on the wireless router to the computer which manages the router (known as the management computer for the purposes of this lab).
- On the management computer, open Internet Explorer and connect to http://192.168.1.1. (or the administration address of your wireless router) and log in. The management interface should display in the browser.
- Navigate to the wireless settings to access wireless MAC filter.
- Locate in the table the MAC address of the computers you wish to deny access. Remove the MAC address from the filter list for all lab computers. This will prevent the lab computer from connecting to the wireless router.
- Save the settings.

You are unable to use your laptop’s wireless connection while at work.

Since you are unable to access the wireless connection, you have been using the Ethernet cable connection instead. The cable connection is working fine.
