For setup information, check 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 Apple AirPort website at
www.apple.com/support/airport.
If you cannot 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 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 icon in the menu bar. Up to four bars appear, indicating
signal strength. If signal strength is low, 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 for
more information.
