no wpa option in gui, cpu help

[evan]

i am new at this and i have the program loaded up my .cap file converted to hascat format and wordlist ready. the problem is there is no wpa option in hash type on the cpu only. i see it in the hashcat plus but that is only for gpu and i only have a cpu. i cant figure it out please help? im sure its somthing really stupid and simple.
thanks

That is because WPA is NOT supported by the CPU version. You'll need a GPU and oclHashcat-plus.

[evan]

why not?

maybe because atom not implemented it there?

There is no use to try to bruteforce WPA on a CPU, even dictionary attacks are almost useless due to the low speed of a CPU on WPA.

a overklocked Sandy Bridge, Intel 2600K manages to bruteforce about 2000 WPAhashes/s
