Sorry i am not developer or expert, that is just my opinion, and i have the same problem with keyboard once. Mb try fresh instal with wipes dalvik/cache before instling rom and before install gaps after that.
My wifi goes off if phone went into "deep sleep". For example i set to download on torent over night, and after 15-20 mins after i check phone wifi is off, and i need to reboot phone so i can connect again on my Home network. This is my issue on 11cm and 10.2 as well.
