Default wifi not conecting :c

hello all.
i am having this problem where i am not able to turn wifi on.
no matter what rom i flash i am not able to turn wifi on.
i even reverted to stock JB and still.
this happened after i sintalled CWM 6.0.4.4 and flashed CM 11
has this happened to anybody?
im starting to think that my wifi antennas has been broken somehow.
anybody have any ideas on how to fix this?
