[Q] Bluetooth and wifi problem (CyanogenMod/KarbonKat ) topic

Hi, I have been using CyanogenMod 11 (nightlies) for a long time. Now I have switched to KarbonKat which is based on CyanogenMod. When I was using CyanogenMod I had a wifi connectivity problem. That is why I changed my rom to KarbonKat. The wifi problem was solved but now I have a stranger problem. Wifi is not working correctly when I use bluetooth. Do you know why is that happening? Do you know how I can fix it? (current version KarbonKat 1.2-3-20150105-0951) Thanks a lot.
