robz, Worked on token ring (16mb) too, but was not a fan of IBM's implementation. Interesting how you have a lot to say without any technical information to support your argument, but rather take a shot at me and the inference that I am too old to know what the latest technologies are capable of. I'd appreciate if you'd be helpful with a technical explanation rather than the trolling.
Evening people, I mess about with tech bits and have connected a few Roku devices to our fairly sizable GB home network.
As an ex VP of IT for a significant Japanese consumer electronics company ..... (i.e I know little about the tech but a lot about management) I think it's correct to say that current day devices do not default to the lowest common denominator. I should add that I'm also of an age that saw the end of token ring, coax, twinax and all that stuff as well.
You are absolutely right to say that it's off that Roku didn't stuff a decent NW chip in their box for the 0.4 p that it might have cost to do so. But that said, I don't believe it makes a huge amount of difference to day to day performance.
Also I'm fairly certain (though far from expert) that the lower grade performance will not bring down the overall network performance.
I run two 48 port Netgear GB switches in our place connected to a load of Sonos, TV's, CCTV, lighting, a few PC's a couple of NAS's and printers and some other rubbish and I'm not aware that the Roku device (with lower bandwidth) drags the other stuff down.
Bought the UGreen adapter as suggested as had been pleased with their products in the past. And can confirm it works like a charm, I restarted my Roku and it automatically set to wired connection and even saw a slight increase in internet speed by repeatedly testing wired vs prior wireless test with Netflix speed test
They have a list of tested USB ethernet adapters on that page. Although users have indicated that other ethernet adapters have worked for them aside from the ones listed, best to look for USB 2.0 | 10/100 | ASIX AX8877X (ie. AX88772) ( specs to help ensure compatibility.
I bought the TrendNet Ethernet Adapter from Amazon. According to Roku Settings my connection speed increased from low 80MBPS to mid 90's MBPS with the Ethernet Adapter. BUT, for some strange reason I noticed very brief pauses while streaming a variety of different Apps on Roku (with circle going around) ... again just for a second or so, but kind of annoying. Then, I also have Discovery+ subscription on Roku which started giving me messages that my Internet was out and stopped streaming via this App completely even though there was nothing wrong with my Internet. I finally gave up and just returned the Ethernet Adapter back to Amazon for a refund and went back to wireless streaming via this Roku Streambar device.
