I found the error with my wifi...
The access points I bought are not able to work when set to Germany.
No matter which channel I configure, they all are **NOT SUPPORTED**

And by the way... nowhere I found it written, that I have to delete all cap interfaces, before they can get a provision.
When they are provisioned, they never get an update / change.

and they are not able to work with U.S. channels

one of the APs works with Albania, the other does not (same device).

next info: though the config is for 2,4 GHz, provisioning sets 5 GHz and tells me, that it is no supported channel

now the interfaces are partially up and send.
But my devices don't see anything of those wifi's..

at least 2,4 ghz is sending something now. with unsupported channels...

they do mostly the opposite of what I do. I configure them for 5 GHz, they provision to 2.4
I provision config 1, disable 2, and what do they get? config 2...

So, the only way seems to be, setting something and try all settings out, until I get, what I need.

You haven't said what you APs you have. WiFi1 may be 5gHz, BTW.

What makes you think they don't work in Germany? Provide full model code from sticker and also configuration you applied.

As soon as I apply a config with Germany as country, all frequencies, all channels etc are unsupported.
And then there are countries, where at least 1 of 2 identical access points doesn't refuse to work.

Those are RBcAPGi-5acD2nD-XL

Post an example of how you determine "unsupported". is there some error message? It is possible you don't see 5GHz, because due to EU regulation, radar detection process happens some 10 min after booting. Try to not reboot and just wait.

sorry, file too large.

CAPsMAN > CAP Interface
CAP Interface with name cap13 is ok
CAP Interface with name cap14 says ---no supported channel

OP possibly messed around with provisioning rules and tries to provision cap-2ghz-radio with 5ghz-configuration and other way round. That's the most common cause for "no supported channel" if you use the forum search function. e.g. viewtopic.php?t=190635

no. I provision 5 ghz radio with 5 ghz config. Except it might be that the software is faulty...

Most likely software is not faulty and your device fully supports Germany. Post full config and a picture of the issue. We can not help without this info

I don't understand a single word of that linked postings...
There's no 160 MHz
What means rearranged? How rearranged? What should be where?

Listen to Normis. He wants to support you.

On some (older) Mikrotik models wifi1 was 2.4 GHz, and wifi2 was 5 GHz, in more recent one they are the opposite, so - especially when following an older tutorial/forum topic/video - it is easy to invert the two by mistake.

That is the sense of "rearranged" in this context.

160 Hz is a possible width of band on some devices and also in some countries only, ignore the references to it.

ok, but I don't understand it. I'm sorry.
Any guide to study his words and the meaning? Thanks!

Many thanks for that really useful declaration! Honestly, that's more than important to me.
Could you please tell me where I see wifi1 and wifi2 in my crs112 config?

We can close this thread.
I was able to find the root cause.
As soon as I DISREGARD nearly everything what I had to do, what I should do, what the guides say,... I found THE working solution. For now.
Fast provision.
Fast update of provisioning.
Stable wifi. Not fast (only 5/15MBit/s), but stable.
No unsupported channels anymore.
No conflicts in any way.
Fast connected and fast DHCP IP assignment.

I just deleted channels and assigned nothing. Now they work.
