Since there isn't any method yet to fix the OC kernel wifi/mac bug i decided to change my kernel back to the stock one. Simply flashing the kernel did not fixed my wifi.
After a bit of searching i found the right files to fix this problem.
Download the attached file in this post. It contains the kernel from Gtrab and wifi driver from Evil-Z Z-Kernel.
Please use the attached file at your own risk!
Then simply follow the instructions based on Coolbho3000:
Boot into fastboot. Using the fastboot utility, run:
fastboot flash zimage kernel-DZ-1.34.405.5
adb push bcm4329.ko /sdcard/bcm4329.ko
mount -o remount,rw /dev/block/mmcblk0p25 /system
cat /sdcard/bcm4329.ko > /system/lib/modules/bcm4329.ko
