Disabling the Broadcast of the SSID Network Identifier 
For additional security you can disable the broadcast of the 
Network Identifier, SSID. Unticking the Enable SSID Broadcast 
button on the Wireless security page does this. To connect to a 
network that is not broadcasting the SSID it is necessary to 
enter the SSID manually in the network connection properties in 
the Control panel of your PC.  
Configure Wireless Address Authentication 
The following page allows you to configure which wireless PCs 
can access the BT Micro: 
 
By default, any wireless PC that is configured with your 
network’s SSID and channel number can connect to your BT 
Micro. You may want to increase the security of your wireless 
network by creating one of the following lists of wireless PCs: 
A wireless PC blacklist; PCs on this list cannot access the BT 
Micro, but all other wireless PCs can. 
A wireless PC whitelist; PCs on this list can access the BT 
Micro, but all other wireless PCs cannot. 
The Wireless PCs added to either list are identified by their 
unique MAC address. This is made up of six pairs of characters, 
with each character either a number between 0 and 9, or a letter 
between A and F. For example, 00:20:2b:80:2f:30.
