For my part I have here an AVM Frtizbox4040 with OpenWRT 19.07.2 r10947-65030d81f3 / LuCI openwrt-19.07 branch git-20.057.55219-13dd17f.
The problem is, that one of the WLAN transmitters can not be switched on.
While the 2.4GHZ WLAN works, the 5GHZ one doesn't, it can't be switched on.
Under Network/Wireless the radio1 (Generic 802.11nac is set to "Device is not active".
The SSID shows "Wireless is not associated".
If I press the button "Restart", it says "Device is restarting" for a short time, but finally it shows "Device is not active" again.
The log shows the following:

Does anyone have any idea how I can fix this?
