I have to take back my formerly possitive conclusion:
It seems there is a problem with the WiFi on module B, but this bug is older than 4.0.3 (have a look –>here).
- WiFi not reachable anymore
- high load
- no memory left
- syslog flooded with
[766739.132983] ath10k_pci 0000:00:00.0: wmi mgmt tx queue is full
[766739.139376] net_ratelimit: 11 callbacks suppressed
[766739.139407] ath10k_pci 0000:00:00.0: failed to transmit packet, dropping: -28

[766739.165852] ath10k_pci 0000:00:00.0: wmi mgmt tx queue is full
I had to restart MOX to get full usability back again.
I’ve sent diagnostics to tech.support@turris.cz.
