Capsmann indicating "no supported channel" for 5Ghz

I’m running into a strange problem on the 5Ghz channel configuration together with Capsmann.

I’ve the available 5Ghz channel list at http://www.botsenbytes.nl/academy/internet/wifi/wifi-frequenties-en-kanalen.html
when I configure any frequency between 5180 and 5320 Mhz it is complaining that “no supported channel”. When a channel frequency of 5500 or higher is configured there is no complain. The 5Ghz channels 5180 and 5320 Mhz are valid channels when Only AC is configured. What is wrong?

I want to prevent using the DFS channels, so I want to be lower than 5500 Mhz.
Attached also some screenshots

Did you set the country in the configuration?

Yes I did, it is put to "Netherlands".

Could be caused that you selected “outdoor” instead of “any”. Think anything beyond channel 52 is indoor only. There is some more information on this to be found in one of the topics. All my configurations are set to any.

Looks like you are right. Changing to Any seems to fix the problem. Will keep monitoring this.
