Problems with AirPort Extreme Wireless Communication

If you have trouble using AirPort Extreme wireless communication:

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

ÂMake sure you have properly configured the software according to the instructions that came with your base station or access point.

ÂMake 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 might improve reception.

ÂCheck the AirPort (Z) status icon in the menu bar. Up to four bars appear, indicating signal strength. If the signal strength is weak, try changing your location.

ÂSee 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.

Keeping Your Software Up to Date

You can connect to the Internet and automatically download and install the latest free software versions, drivers, and other enhancements from Apple.

When you are connected to the Internet, Software Update checks to see if any updates are available for your computer. You can set your MacBook to check for updates periodically, and then you can download and install updated software.
