I don’t know the answer on your question but probably something needs to be activated. Probably this helps http://forum.tinycorelinux.net/index.php?topic=22155.0

I had the same issue today. For me the problem was, that after plugging in the surf-stick(Huawei E3372) there was an auto generated entry in /etc/network/interfaces, but the gateway ip was wrong, it should be 192.168.8.1 but was the same as the one of my wifi network (maybe I played around too much with dietpi-config :stuck_out_tongue: ), also I only got a stable connection with a static IP.
So I removed that entry and created:
/etc/network/interfaces.d/surfstick

# surfstick
allow-hotplug eth1
iface eth1 inet static
  address 192.168.8.100
  netmask 255.255.255.0
  gateway 192.168.8.1

all conifgs in*/etc/network/interfaces.d* will be loaded by /etc/network/interfaces
after a reboot it worked :smiley:

some useful commands:
to see all active interfaces: ip route
to check connection of wifi: ping -c3 -I wlan0 1.1.1.1
to check connection of surfstick: ping -c3 -I eth1 1.1.1.1
