Multiple problems on Vaio F11: Atheros always disabled, low idle cpu speed

[Funky frank]

Hi,

 

I installed OSX 10.9.4 on a Vaio F11 with a Core i7 q720 (Nehalem / Clarksfield) and Gefore GT 330M using Clover. In comparison to OSX 10.6.8 I still have these problems:

 

1. Airport Extreme (168C, 002a) Atheros 9280 is found out of the box, but it is always disabled and I cannot enable it!  Any ideas here?

 

2. The CPU idle speed is horrible slow, so slow that even the mouse pointer lags. I don't know if the micro kernel cpu powermanagement is activated or the generic AppleIntelCPUPM... What mode would be better for my CPU ?  I tried to generate a proper SSDT using ssdtPRGen.sh, but it doesn't know my cpu model!  Have can I easily higher the idle clock? How can I determine the maximum speed?

 

Thanks for help!
