I can confirm did a clean install and always get some random WIFI disconnects. ROM is fast and stable its just sometimes disconnects from my WIFI for no reason. Hope its get fixed soon because i like this ROM more than stock and i need WIFI always on for receiving messages from friends and family via Facebook, Whats Up, Viber etc.
Have a nice day
Have you tried this:
Go to setting-location-tap 3 dots menu on the right top and disable wifi scanning?
I have no problem with wifi, even with dirty flash though)
