I tried other hardware (atheros wifi, instead of intel advanced 6300) 
and that works. The only thing is that I have to flash my bios because 
of hardware restrictions (lenovo x201).
Not shure about the options: patching the kernel or flashing the bios. 
Or an ugly usb device...
Newer firmware did not help.
Patching the kernel did help. I put the patch file in 
/var/lib/lunar/moonbase/zlocal/_patches/linux/"my patch". And it is 
called after the configuration.
About the patch:

"The systemd commit below can delay firmware loading by multiple
minutes if CONFIG_FW_LOADER_USER_HELPER=y.  Unfortunately no one
noticed that the systemd-udev change would break new kernels as well
as old kernels.
Since the kernel apparently can't count on reasonable userspace
support, turn this thing off by default."
