53 Chapter 4 Problem, Meet Solution
If your ISP provides only one IP address, then you must have a router capable of
sharing the connection, also known as network address translation (NAT) or “IP
masquerading.” For setup information, see the documentation provided with your
router or ask the person who set up your network. You can use an AirPort base station
to share one IP address among multiple computers. For information about using an
AirPort base station, check Mac Help or visit the AirPort Extreme website at
www.apple.com/support/airport.
If you can’t resolve the issue using these steps, contact your ISP or network administrator.
Problems with AirPort Extreme Wireless Communication
If you have trouble using AirPort Extreme wireless communication:
 Make sure the computer or network you’re trying to connect to is running and has a
wireless access point.
 Make sure you’ve properly configured the software according to the instructions that
came with your base station or access point.
 Make sure you’re within antenna range of the other computer or the network’s
access point. Nearby electronic devices or metal structures can interfere with wireless
communication and reduce this range. Repositioning or rotating the computer might
improve reception.
 Check the AirPort (Z) status menu in the menu bar. Up to four bars appear,
indicating signal strength. If the signal strength is weak, try changing your location.
 See AirPort Help (choose Help > Mac Help, and then choose Library > AirPort Help
from the menu bar). Also see the instructions that came with the wireless device.
