Not on this mobo, as it's new, so don't know.

But on my older Soekris net6501. There was the same problem, that the system crashed and freezes, when WiFi was enabled and used, with same type of Compex WiFi cards. But I know, that the Soekris was running 1-2 years just stable, before that problems there also started. The miniPCIe were direcly inserted without any adapter.

Just a wild guess, as I am running Gentoo and my own kernel. Could be something missing in my kernel, which could lead to this problem?

I don't think, as the active and the passive adapter do show the same error.

Well, other PCIe (e.G. USB 3.0, S-ATA) cards are just working fine..

That does not seem to work?

iw dev wlp7s0 set txpower fixed 15
command failed: Operation not supported (-95)

iw dev wlp7s0 set txpower limit 15
command failed: Operation not supported (-95)
