Advertisements I know this is discussed a bit under the USB C thread but as far as using a hardwired ethernet connection to the TS4K I found the following worked for me: UGREEN Ethernet Adapter for Fire TV Stick 4K, All New Fire TV 2017, Chromecast, Google Home Mini and more Streaming Sticks, Micro USB to RJ45 Ethernet Network Adapter with USB Power Supply Cable 3.3ft from Amazon. Apparently some have had similar success with the Chromecast adapter but that seems to be an older chipset from the one that is currently sold by Google. That newest one from Google did NOT work for me and I tried all the suggested tricks. The UGREEN adapter worked instantly on reboot and showed the ethernet connection. I am not sure what the TS4K prioritizes but it looks like ethernet over wireless. I turned off the wireless just to be sure. Now it just remains to be seen if I get the stability I am looking for on a wired vs wireless connection! So far so good as I was having a lot of buffering issues which required reboots in the past especially with HBO Max as well as Sling. Those appear to be resolved as of now. BTW this is not a USB C connection, it is run into the micro USB power connection on the TS4K. It seemed like trying to obtain a USB C ethernet connection requires more parts and I wasn't into it lol. Even though I am running off 1 gig fiber the 10/100 speed is in my belief plenty to run whatever programming I toss at it.
