The client often loses the connection.

Hi,
The client often loses the connection.
I'm using a server on a Raspberry Pi 3. Pings from client to server are not lost.
How can I fix it?

Dont use wifi on the pi3, use ethernet instead, or use a decent dual 2T2R board like the gl-mt300nv2

#5

Are you using it over a VPN or plain ethernet? If you are getting issues like this over plain ethernet i think there is some hardware problem with your pi or network.

#6

plain ethernet

#7

I think there is some hardware issue.

#8

I am also experiencing this. I have a pi 3b+ wired via ethernet. Would using a VPN eliminate these dropouts?

#9

What is your latency graph looking like? Right click on the USB server in the client and select Properties -> (Latency)
