I have a MacBook, black 2006 that gives an error when joining the AirPort network.
I have tried zapping the PRAM http://michaelhyatt.com/fix-for-wireless-connection-problems-on-macbook-pro.html
I tried turning off the IPv6 address, moving my current network up to the top of the list, deleting old networks and the keychain repair.
My iMac works fine, iPhones, iPads and other PC laptop.
Any other suggestions?
Thanks in advance.
