If you have trouble using AirPort Extreme wireless communication
• Make sure you have properly configured the software according to the instructions
that came with your AirPort Extreme Card or base station.
• Make sure the computer or network you are trying to connect to is running and has
a wireless access point.
• Make sure you are within antenna range of the other computer or the network’s
access point by checking the AirPort Extreme signal level. Check the AirPort status
icon in the menu bar. Up to four bars appear to show signal strength.
Nearby electronic devices or metal structures can interfere with wireless
communication and reduce this range. Repositioning or rotating the computer may
improve reception.
• See AirPort Help (choose Help > Mac Help, then choose Library > AirPort Help from
the menu bar) and the instructions that came with the wireless device for more
information.
