Default [Q] no wifi with latest thunderclap kernel

hey all,

I got an annoying problem....am sure someone over here experienced the same.

I have installed the latest version of cm, which works fantastic.
However i would like to use the thunderclap kernel.

Every time i put the last kernel on my phone my wifi stops working.
when i look it up, it stays grey....also mac adres etc. is empty.

Someone got an idea how to fix this?

Thanx,
Jadevinski
