Yeah, on a PC the adapter works just fine, I get Gigabit speeds no problem testing with iperf3. It's my C9 OLED that's having problems with it. Although weirdly I do need to do a network reset in Windows to get it to not bug out every time I plug it in. Maybe that's part of the problem?

I ended up picking up this cable matters ethernet adapter (https://www.amazon.ca/gp/product/B00BBD7NFU/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) but it doesn't work properly on my 65C9PUA. The TV gets an internet connection, however it caps out at 100mbps just like the onboard lan. Not sure if anyone has other recommendations for alternate adapters. I would prefer to not need to buy 4 or 5 of them to see what works. Wondering if Cable Matters changed how they make their adapter considering it seems like more people are posting that it doesn't work properly.
