## Wireless MAC Filter

  The Wireless MAC Filter allows you to control which wireless-equipped PCs may or may not communicate with the router depending on their MAC addresses. For information how to get MAC addresses from Windows-PCs, see MAC Address Cloning for detailed instructions.
  To set up a filter, click Enable, and follow these instructions:
  1. If you want to block specific wireless-equipped PCs from communicating with the router, then keep the default setting, Prevent PCs listed from accessing the wireless network. If you want to allow specific wireless-equipped PCs to communicate with the router, then click the radio button next to Permit only PCs listed to access the wireless network.
  2. Click the Edit MAC Filter List button. Enter the appropriate MAC addresses into the MAC fields.
     Note:
     The MAC address should be entered in this format: xxxxxxxxxxxx (the x's represent the actual characters of the MAC address).
  3. Click the Save Settings button to save your changes. Click the Cancel Changes button to cancel your unsaved changes. Click the Close button to return to the previous screen without saving changes.
  To disable the Wireless MAC Filter, keep the default setting, Disable.
