Android; Connection over usb c Ethernet adapter

It appears syncthing android does not allow communication over a usb c ethernet adapter. Is this the case and is there a possibility to allow this feature in the future?

Thanks

I don’t think Syncthing has any opinion on where the ethernet comes from, as long as it’s a working network connection.

I had a working ethernet connection on my android phone with wi-fi disabled and Syncthing would not connect/ communicate through that network connection. I had to enable wi-fi and establish a wi-fi connection for it to work. Obviously, wi-fi this is the most common way and convenient way to connect with an mobile android phone, just thought it would be nice to have the other option as well.

I would suspect a routing problem on the Android phone.

Memory does NOT serve, and I cannot be certain this actually occurred as I describe it. But I cannot think of why else I remember this with such (vague) clarity:

I recall wanting to speed up initial seeding of a good 600GB of a photo gallery to an Android device. Finding the wifi speed to lackluster, I used an USB Ethernet adapter, I think I got an excellent 20-25MB/s. Yet I remember being amazed at the speed, so if you told me I had seen 50, I wouldn’t be too surprised (unreliable narrator). The phone is not in my hands, so I can’t verify now…

  • Samsung Galaxy S24 Ultra
  • USB-A 2.5GBe adaptor
  • Type C hub, powered, to convert the A to C but also to charge the device at the same time
  • Raised surface, all participants got hot
  • Maybe needed to touch a notification or flip a switch somewhere after plugging in the adaptor to enable it
  • Ethernet icon appears where wifi would afterwards

I know nothing about Android, or the Linux that powers it, but I feel mobile OS’s make the app so far distanced from the underlying hardware they probably wouldn’t know where their internet came from (mobile, wifi, USB, etc) unless they asked the OS explicitly.
