Odroid C0 Usb to Ethetnet Empty Gateway Problem

Unread postby pcmgogo » Thu Dec 21, 2017 5:59 pm

Hi Everybody,
I am trying to connect network via USB to Ethernet controller with my Odroid C0. When I tried to connect with DHCP option, ethernet connected to network but could not reach internet. Then, I tried to connect with Static IP option, I noticed Gateway was empty. I set gateway value manually, it connected properly.
I have been using Odroid C2 for more than 1 year without any problem with same cable, same network device. I check these issues from C2 ethernet settings, everything looks properly. Gateway value updated from DHCP, it can connect internet with both options(static and dhcp). But I cannot connect internet with Odroid C0 DHCP option, because of empty gateway value. When I clicked Gateway setting from Static IP Settings window, gateway value already filled, then I clicked OK button, It is not updated (attached pictures). When I clicked and I filled gateway value manually, It is updated and connect properly.

I tried with Odroid's Published Android OS, and my own builds. All of them has same problem.

Are there any suggestion?

Clicked gateway, it was filled but just hint, no real value.

Can you ping to your router on terminal app?
Which USB-to-Ethernet chipset do you use?

Thanks for your quick reply. I checked from device, it says RD9700 USB 2.0 Fast Ethernet Adapter.
I tried to ping to router, it says Destination host unreachable.
I discover a new situation, If network cable unplug and plug after boot, It connects properly, still Gateway which is in the static ip settings, is empty.

I think RD9700 driver is not available in C0/C1 Kernel.
I couldn't find it in Kernel configuration file.
