PCE-AC66 slow on 10.9.

I have just updated my hackintosh from 10.8.5 to 10.9 and now i am able to use my PCE-AC66 finally but, i am getting very slow speeds. It uses the new broadcom BCM4360 chip inside the wifi card. Is there a patched BCM4360 kext i must use to get the full speed or is it my settings?
