Even so I don't want to teach you wrong, a quick look at wikipedia reveals a slightly different view on this: 
https://en.wikipedia.org/wiki/List_of_WLAN_channels#5.C2.A0GHz_.28802.11a.2Fh.2Fj.2Fn.2Fac.29.5B17.5D

I mean that's exactly what's the linux kernel reg domain stuff ( http://wireless.kernel.org/en/developers/Regulatory/processing_rules ) is meant to manage, isn't it?

That's the reason I wrote the mail in the first place. I wasn't able to use AP mode at 5G. Wich I found out by myself and didn't read somewhere e.g. at http://wireless.kernel.org/en/users/Drivers/iwlwifi . If it's that clear and obvious, why not state it there? I would have saved me 50 Euros and some hours...

Just a feeling, but I guess asking something like "Why?" wouldn't help me in understanding, right? This is just some marketing decision at Intel (don't support 5G AP mode in consumer WiFi cards) developers have to follow.

Does anyone have a working setup for 5G AP mode with linux using a (m)PCI(-e) card? Or are there only SoCs available for this job? 

Thanks,
