BUT... Weirdest thing... I've been shuffling back and forth between a couple of backups I have: Mahdi, CM11S, CM11 M9 and so yesterday I restored CM11 M9 and this morning on my way to work my phone actually reconnected by itself to the WiFi on the train. AND also now that I'm at work. It has NEVER done that before.
I have no idea what has been done. I have removed one app that I installed to try to analyze what was wrong (Smart WiFi Toggler). I also got a new router at home but that really can't make my phone connect to other networks... right?
It's really weird and I'm almost afraid to touch my phone now out of fear that WiFi will stop working...
