Flashing to stock is different in that it wipes FATFS via task 28 (the storage memory part of the ROM).

As I said before, it could be any number of things causing your wifi to partially not work. But task 29 and reloading a fresh ROM almost always fixes issues like yours. If you wanna go nuts, run task 29, then flash to your carrier's stock rom, then activate your phone and call your voicemail to ensure it works, then load Mighty again

Well it took up half my day but it worked! Thank you so much!
