Hey,
I have a Raspberry Pi and a Rock Pi connected to the router through WiFi at the same time, and when I SSH to Rock Pi, I found that the input has some delay.
When I checked Ping, I found that its value was very high and the Raspberry Pi was very small.
What can I do to improve it?
My Rock Pi is working with Debian desktop (rockpi4_debian_stretch_lxde_armhf_20181105_2120).
