Problems with AirPort Wireless Communication

If you have trouble using AirPort wireless communication:

åMake sure you have properly configured the software according to the instructions that came with your base station.

åMake sure the computer or network you are trying to connect to is running and has a wireless access point.

åMake sure you are within antenna range of the other computer or the networkÕs 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.
