I have a OnePlus5T that runs PostmarketOS (console, no GUI). I use pmbootstrap to flash the image and it serves me well for the most part. To make the internet connection more stable, I wish to connect the phone to the router using an Ethernet adapter.

I have borrowed a Porttonics Ethernet 8in1 adapter and works well on other stock android phones. I can use ethernet nicely and surf sites on those phones

I seem to be unable to do this with Postmarket OS. Based on what i have read, I think the kernel needs to be tweaked so it can connect and work with the router. Does anyone know how to do this?

(This is my second post on this topic. Apologies).
