Improving USB tethering speed? (sopuli.xyz)

Hello, I have a shiny new 5G connexion which I intend to use as a complement to my bad home internet.

I see very different speeds depending on the method, using speedtest.net:

  • Directly from the phone: ~200Mbps
  • From the PC, using the native USB internet sharing feature: slow ramp up to ~30Mbps
  • From the PC, using "PdaNet" in USB debug mode: slow ramp up to ~200Mbps

I don't understand why the native method would be slower, a lot of people on the internet mention that ISPs tend to throttle tethering, but PdaNet has a feature to hide the tethering and I get the nice speed without using this feature. The PdaNet approach is a more cumbersome with specific applications both on the PC and the phone. Anyone knows of a method to improve the native USB internet sharing?

  • Phone: Fairphone 4
  • Android 12
  • ISP: Sosh (subsidiary of Orange, France)
  • PC: Windows 10

Who's your ISP? I'd suspect it's the ISP treating tethering traffic differently. I notice that on my phone (AT&T postpaid), my phone and tethered computer even get different IPv4 addresses. I'm not saying performance should be identical if they are sharing an IPv4 address, moreso just showing that ISPs can handle tethering traffic differently.

EDIT: just saw you're on Orange, oops! I don't know how they operate, they could be handling tethering traffic differently from native mobile.

That's wild, I don't even understand how they could allocate different IP adresses, I hope it's not the issue here
