    I just used ubuntu and downloaded both aircrack-ng and macchanger packages as well as dependencies. Afterwards I just followed the above command list. Instead of defining a fixed mac address on macchanger I just used ‘macchanger –random’ and made note of the new one for each of the remaining commands. It is easier if you do aireplay and aircrack on their own windows. You can leave the latter one running even while airodump is running as it will retry every 5000 IVs collected.
