Okay so I'll start from the top:
1) http://samsung-updates.com/device/?id=GT-S7560M My stock firmware (baseband: S7560MVLBNA5) was the one circled in the picture in attachment.
2) Flashed TWRP Recovery via ODIN, from here http://forum.xda-developers.com/show....php?t=2682888
3) Placed CM11 and Gapps provided by jonypx09 in sdcard and flashed them via TWRP.
4) I didn't have wifi problems but installing this modem by .rootCoder. from here made it much better and reliable: http://forum.xda-developers.com/show...7#post53419117
and that's how everything came out perfect Thanks to all the devs who created the the rom/recoveries/modems
EDIT: ps. if you decide to use TWRP (Instead of CWM), don't ever boot into recovery via the OS(power menu) or ANY app that lets you boot into recovery because your device will forever boot into recovery (even with 8 second power button reset). You'll have to end up re-flashing the recovery ONLY (not the whole ROM).
