Wlan0 disconnecting

Software SW help
1

Since last update is wifi practically unusable - I am using first card with 5Ghz and it is often disconnecting. Last example:

2016-12-12T23:02:22+01:00 info hostapd[]: wlan0: STA 2c:f0:a2:be:71:72 IEEE 802.11: disassociated due to inactivity
2016-12-12T23:02:23+01:00 info hostapd[]: wlan0: STA 2c:f0:a2:be:71:72 IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE)
2016-12-12T23:02:35+01:00 notice netifd[]: Network device 'wlan0' link is down

In that “inactivity” time was connected at least one phone and laptop. I am seriously thinkong about deactivating wifi at all, use omnia as “only” router and use for wifi some more stable solution.

Same here but with wlan1

Here is an example form the system log but it keeps going on:

Here is the kernel log. Could it be related with ATH10K, as @czbird mentioned?
