Default WiFi won't work on rooted 4.4.2 stock rom

As the header states, after rooting 4.3 and installing safestrap recovery, I decided to flash pre rooted 4.4.2, since I didn't want to loose camera features when going with GPE based roms. Well, my WiFi stops working after a few days, and won't start unless I do factory reset.
On top of that bluetooth, when connected to a speaker or a car audio skips transmission a few seconds at a time notoriously. Any thoughts/ideas?
