Haha, it works now.
Just unplug it from my router, and connect it to my windows PC(really hate mac removed ethernet interface XD).
Data transfer this way:
My House Router (wifi)-> VoCore (ethernet)-> My PC.

VoCore alloced 192.168.61.190 for my win pc.

Now I am sending this blog through the VoCore 🙂 The tests move so smoothly.
Later will watch a movie or do something using heavy network load. And put my phone near it as an interfering signal(that is real, once my phone ring, my HDMI monitor just go black and do not work at all! It is about 20cm from the HDMI cable) to check if there is any problem for high frequent data transfer. I have confidence for that, due to the wire is very short(about 300~400mil) and every data pair length is just same(<10mil, but impedance about 80ohm).

Connect dock to ethernet.

Looks like there is nothing wrong in hardware part.
LuCI detected the ethernet port0.

There is something wrong in the software part, I can not connect to the ip which alloced by my house router. VoCore’s AP+STA is still working, but ethernet not. I find the VoCore sta mac and the ethernet mac in my HyFi router DHCP client list.
192.168.1.103 is wwan(sta mode).
192.168.1.102 is the ethernet.

This is ifconfig result.

Looks like eth0 is following br-lan 192.168.61.1(same mac), so eth0 can not assigned to 192.168.1.102 auto. The two routers are fighting 😀
If I force eth0 ip to 192.168.1.102, what will happen? I will check later.

For now, the main hardware functions: Ethernet/Wifi/USB/GPIO, have passed two.
