Looks like you haven't pressed the Enter key after "dmesg|tail" and there's no output for that one, it could be helpful, because it should contain the output from wpa_supplicant.
Yes, CCMP is AES with additional stuff, in a nutshell. However it not only should be similar to what SpiderKenny has in the instructions, but it should also match your WiFi infra's settings :-) What do you have set there?
