As of Nov 2021 Walmart is still selling the Onn UHD Android TV set top streaming box. This is essentially an Android Chromecast rebranded device. While it's runs super with it's quad core CPU and very fast on 5ghz WiFi, I wanted to run it on an RJ-45 Ethernet adaptor and of directly wired to my home router..
So wanted to share this for those interested.
I found a low cost adapter on Amazon for $6.99 and it was a simple plug and play. Brand is JacobsParts USB to Ethernet adaptor. You'll also need the OTG cable that's like $3 I tested my internet speed using my comcast that's a 100mbps service. And I got an astounding 120mbps download speed and very hard to believe 750mbps upload speed. Did the test several times with equal results. There are more expensive options but just FYI this cheap Ethernet adaptor works perfectly on the Onn UHD streaming box.
Man that upload is hard to believe- doesn’t USB2(or micrOUSB) max out at 480mbit? Someone correct me if I’m misunderstanding.
