High latency ping every ~10 sec

Hello,


I don't remember when it started due to I usually do not monitor such things, but recent weeks of monitoring I experience latency spikes over Wi-Fi.

That's MacBook Pro Mid'14, macOS 10.13.6, 5GHz Wi-Fi network.


This is ping log example, pinging the router itself:
