Input lag sshing to raspberry pi 3b while its running docker
Solution 1:
Same problem here.
I tried to ping $ROUTERIPADDR and i see random From xxx.xxx.xx.xx icmp_seq=8 Destination Host Unreachable.
The IP address is related to a network interface generated by docker containers. You can see them with ifconfig, should be something as veth...
As soon as i stop those interfaces with ifconfig veth down, laggyness disappers.
