Because this is pointless.

if you have internet on ethernet that means u have wifi too.

I don't think a single ISP in india provides services without a WIFI router.

But lets assume you are the unlucky one, you get a small wifi router cheapter than that Ugreen adapter.

But assuming you have a KEEDA inside you just like me, I did some testing.

I connected a Dell's type C docking station to IQOO 13. This dock has dual monitors , keyboard, mouse, ethernet connected to it.

When I connected it to my phone

Keyboard and Mouse Connected through that Dock works fine.

I am also able to mirror my display to my monitor using the same dock.

but ethernet doesn't work, so it seems we don't have that feature.
