Choosing the Network Mode
Choose 802.11b/g Compatible from the Mode pop-up menu if computers with 802.11g 
or 802.11b wireless cards or will join the network. Each client computer will transmit at 
its highest speed.
Choose 802.11g Only if only computers with 802.11g wireless cards will join the network. 
The transmission rate of the network will be at 802.11g speed, up to 54 megabits per 
second. Computers with 802.11b wireless cards will not be able to join this network.
Choose 802.11b Only if computers with 802.11b wireless cards will join the network. The 
transmission rate of the network will be at 802.11b speed, up to 11 megabits per 
second. Computers with 802.11g cards will be able to join this network, but will join at 
802.11b speed.
Setting Wireless Options
Click the Wireless Options button to set the multicast rate of the network, enable 
interference robustness, and adjust the transmitter power of the base station. Settings 
in this pane can reduce the range of the base station and should not be modified 
without good reason.
Setting the Multicast Rate
Use the “Multicast rate” pop-up menu to set the multicast rate. Increase the rate to 
improve the performance of certain types of network activity, like video or audio 
streaming. The increase in performance will reduce the range of the wireless network.
Enabling Interference Robustness
Select “Enable interference robustness” when the base station is in an environment 
with other 2.4 Ghz devices that can interfere with your network. Devices that can cause 
interference include cordless telephones, some television repeaters, and microwave 
ovens. For more examples of devices that can cause interference, see “Items That Can 
Cause Interference With AirPort” on page 80.
Note:  Client computers using AirPort Extreme wireless cards must choose Interference 
Robustness from the AirPort status menu in the menu bar to take advantage of this 
feature. 
Adjusting Transmitter Power
Use the Transmitter Power pop-up menu to reduce the power the base station uses 
and limit the range of the base station. This may be useful in areas where many base 
stations are in close proximity to each other. Client computers will need to be closer 
to the base station in order to join the network it creates. Choose a milliwatt setting 
from 1 to 32. The larger the number, the greater the network range.
To set more advanced security options, see  “Keeping Your Network Secure” on 
page 56.
