Thanks for hinting me to this thread, I have not seen that before. I 
read in this thread and the linked ones and understand the issue now a 
bit better.
It seems like that basically many (all ?) Compex cards are affected by 
this, and probably many pcengines users (like me).

Reading also this:
gives me the impression that in this case, I would have to ask 
pcengines/compex for a custom regulatory.bin. Has anyone tried that already?
It also sounds like that many vendors have used this value completely 
wrong. Does anyone know if new Compex cards have the same issue?
Or in other words: what would be the correct value to put there, because 
it seems there are only two options: ship a custom regulatory.bin or 
ship the card with the country burned in it, where the card shall be used.

There is this patch:
However, it simply disables it completely.
I have not found the patch, which would enable a parameter to set it 
during loading of the module so far though.

Yes, for me this is sad. My setup worked for over seven years and broke 
because of an update. Of course I can now start to build kernels every 
It sounds like I should throw away the Compex card and buy an 
off-the-shelf access point... I was thinking about buying a new card, 
but as there are so many reports regarding Compex cards, I have no hope 
that it will work then.
