Yes, sorry for not being clear about this.

So, if I understand well, the new behaviour (non working AP with ac) is 
expected, given that the device was not provisioned with the settings 
specifics to my zone? And to prevent people from operating an AP with 
the wrong settings, we force them to use hardware that is specific to 
their zone? If that's the intention, I'm not sure it is very effective: 
I can still buy a German wifi card and use it in France. It will 
probably suits most of the hardware vendors, though: people moving to 
another country are forced to buy new stuff and they can't buy cheaper 
stuff abroad, but, seen from another angle, it sounds like planned 
obsolescence.

The vendor of my (new) hardware is from Switzerland, and is selling to 
(at least) everywhere in Europe, and they sell the same hardware (that 
used to work) for everybody. So, now, they are supposed to sell 
specific hardware for each country? I think the card was not 
provisioned with a specific country (I'm in France, and I tried FR, CH, 
US,  ...), so I guess I have to throw it to the bin anyway (and they 
should do the same with all their stocks).

I hope I have misunderstood your message, else I have to admit I'm a 
little disappointed... Thanks for your explanation, though!

If that's really the intention, is there a workaround for irresponsible 
people like me, who just wan't to avoid buying new stuff?

Regards,
