Wifi getting switched on and off frequently

[archz2]

I am using AOSP Marshmallow AOSP ROM on my Lenovo A7000 phone. Since then my wifi keeps getting switched off by itself and turns back on without any reason.

I also checked in my advanced wifi settings that my wifi is kept on during sleep and it was enabled. What should I do to fix this problem? I also flashed the ROM again by wiping data, dalvic, cache and factory reset but the problem persists. I also tried flashing DARE aosp marshmallow rom and marshmallow aosp beta 2 ROM. This problem is seen in these roms also.

If you flash the original stock firmware back on your device, does the problem still persists?

I would think that the ROMs developers would be more capable of answering these questions about the specific ROMs.
