    For this to work in Lion OS X 10.7, there is one extra detail.

    Before issuing the address change:

    sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport -z

    Then wait at LEAST 10 seconds before proceeding with the command in the original article.
