Chapter 3 AirPort Network Designs 23
Setting Additional Wireless Options
Use the Wireless Options pane to set the following:
 5 GHz network name: Provide a name for the 5 GHz segment of the dual-band
network if you want it to have a different name than the 2.4 GHz network.
 Country: Choose the country for the location of your network from the Country
pop-up menu.
 Multicast rate: Choose a multicast rate from the pop-up menu. If you set the
multicast rate high, only clients on the network that are within range and can
achieve the speed you set will receive transmissions.
 Transmit power: Choose a setting from the Transmit Power pop-up menu to set the
network range (the lower the percentage, the shorter the network range).
 WPA Group Key Timeout: Enter a number in the text field, and choose an increment
from the pop-up menu to change the frequency of key rotation.
 Use Wide Channels: If you set up your network to use the 5 GHz frequency range,
you can use wide channels to provide higher network throughput.
Note: Using wide channels is not permitted in some countries.
 Create a closed network: Selecting a closed network hides the name of the
network so that users must enter the exact network name and password to join
the AirPort Extreme network.
 Use interference robustness: Interference robustness can solve interference
problems caused by other devices or networks.
