what is the WEP or WPA password?

This keycode/password was established when the AirPort base station was setup for wireless encryption. If you didn't do this, you can still find this keycode in your OS X keychain. The Keychain Access application can be found in the \Applications\Utilities folder on your Mac.

Look for a key with a "Kind" of "AirPort network password." Double-click on the key and then select "Show password." You will need to enter your Keychain password to reveal the AirPort network's password.

My iMac G5 is connected to my WPA2 enabled network. I have an old G3 iMac wcich i need to buy an aiport card for, will i be able to connect to the network, or will i have to downgrade it to WPA or even WEP?

Here are the minumum requirements for AirPort WPA or WPA2...

thanks very much

Thanks for the post! I have been puling my hair out trying to connect my work laptop to my AirPort. I thought I had the correct WEP password but I didn't and your tip helpe dme see that.

Curious though, why was my iMac able to connect to the internet through the airport when I was entering the wrong password in the Network area of System Preferences? Is it because I manage my Airports from the iMac so there really isn't any need for a password per se. No big deal, just curious. Thanks again. Apple Discussions save the day again!
