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.

Nearby electronic devices or metal structures can interfere with wireless communication and reduce this range. Repositioning or rotating the computer may improve reception.

•Check the AirPort Extreme signal level.

Check the AirPort status icon in the menu bar. Up to four bars appear to show signal strength.

•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.
