After logging into the SMC2870W, all the System Information will be displayed.
You can proceed to another configuration page using the navigational menu on
the left.
Go to the Status | Associations page to view all the wireless clients that are
connected to your SMC2870W. The MAC Addresses of the clients will be shown.
This is helpful if you plan to configure MAC Address Filtering in the future. You
can simply highlight the appropriate MAC Address, copy and paste it in the
section called Wireless | Access List.
