Yes, sorry for not being clear about this.
That sounds like the expected behavior for any device that has not been calibrated and provisioned for a specific country where regulatory rules allow operation on the 5 GHz band. I understand that this may look like a regression since the commit removed functionality, but it feels like a bug fix to me since that functionality should not have been enabled by default in the first place. The goal here is to avoid inappropriate operation on the band without explicit configuration to enable such operation. In AP devices, the device should have been provisioned for a specific country to be able to enforce the correct frequency range restrictions. The safe default for a device that does not have such explicit configuration within the WLAN component itself is to use the world roaming mode which prevents initialization of radiation (i.e., does not allow AP mode to be started but allows station mode operation to connect to an already started AP) on the 5 GHz band.
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?
