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).


Sorry for the late reply. Did you get the phone to supply power via its USB port with postmarketOS? I did not get that to work. According to the wiki, this is a known issue: “The phone won’t supply its own power, so you need either a powered hub or an extension cable wired up to 5v. Some hubs may refuse to work without power being supplied from the port however.” See the OTG doesn’t work on the Wiki page
So there are 3 power modes in “normal” USB; 500mA, 1A, and 2A, all three of these at 5V. The 6T can only deliver 500MA 5V.
There is also provision in the USB spec over USBC for negotiation of power delivery that allows also changing the voltage to deliver more power. The 6T cannot do this, it lacks the usb PD circuitry.
However, it can do org (change to “target mode” to become storage for, say, a computer to access its storage. The 6T can do this with android, but you’re right, I haven’t been able to get it to work with pmos.
I do a lot of tinkering and development with GPS, and I use a few Blox GPS dongles. These need a bit of power to heat the ceramic antenna and atmo pressure sensor. These work with pmos.
