I have Dell Latitude 7470 with Ubuntu 16.04 and NanoPi (RaspberryPi-like ARM device) with Debian 8, connected by the USB/Ethernet cable (ARM device have ethernet). Usbnet interface on laptop is configured with /etc/network/interfaces, I also have standard ethernet interface and WiFi connection, ruled by NetworkManager.On the laptop side the interface is configured with the following lines in /etc/network/interfaces:allow-hotplug enxac293adaf70f iface enxac293adaf70f inet static        address 192.168.1.1/24        gateway 192.168.1.2The interface on the ARM side  was configured with the following:auto eth0iface eth0 inet static        address 192.168.1.2/24        gateway 192.168.1.1As a result I have the connection between my laptop and ARM machine, but it is very unstable: ping shows up to 85% packet loss, and SSH session stops every 2-5 minutes with No route to host error. Unplugging/plugging the cable helps, but in a pair of minutes a connection breaks again.How I can get more information about this problem? What may cause unstable usbnet connection? How to increase connection quality?
