Jellybean wifi issue with Mac Internet sharing

I have this recurring issue with all Jellybean roms I have tried ( Stock Poland, Android Hd, Omega, Foxhound) where i lose internet connection over wifi every 3-5 mins and only way to recover it is to toggle wifi on and off. The funny thing is this happens only when i use my gf's macbook pro as a wifi hotspot (internet sharing over mac wifi).

There are no problems with ICS roms. I have tried stock, perseus, siyah and speedmod kernels to no avail.

Can somebody help me?
I do not want to get a wifi router as my gf needs the wired lan connection for her work
