It was wifi, my connection speed with speedtest over wifi was 100Mb down and 30Mb up.

I should probably note I was also sitting next to my wifi router, so I’m not sure that a wired connection would’ve made a noticeable difference.

Even right next to the antenna, wires will have less latency and packet loss than wireless.

Sure but it shouldn’t be noticeable. For example, I can play Counter-Strike on my computer itself just fine over wireless without the latency issues.

From my experience, I think it is. A non-small part of multiplayer game engineering is to handle latency. With streaming you have none of that, and even if the connection just stutters for a few 10's of ms you will get a horrible playback experience.

Game streaming is most comparable to live video streaming with a frighteningly small buffer (< 10 ms).

The GeForce Now client itself told me my connection was good enough for gaming... I’m not arguing that wired cables aren’t faster, but these streaming services aren’t advertising based off of that and their own clients aren’t requiring that level of performance either.

I've tried GeForce Now also, the client told me everything was fine over Wifi (but it wasn't). Switched to wired, and again everything worked perfectly. I'm in the same room as my router.

I'm just saying that my guess is that this probably has nothing to do with your ISP or net neutrality, and more with technical limits of wireless connections. But I could of course be wrong... Try it with ethernet and see how it goes, I just have a long cable I temporarily run through the room when I wanna play :-)

(And yeah, I think it's kinda fishy that they don't make it clearer if/that wired connections can make big improvements. Look around the subreddits about these services, or their support pages and you'll see that people recommend ethernet, and the vendors first recommendation when having trouble is to use wired ethernet [0], [1])

I have Ubiquiti home networking, and sometimes play GFN or Steamlink over wifi a few feet from an AP, but just trust me that wired is always better than wifi, regardless of what a rudimentary connection test tells you. If you have the option of trying wired, just do it and see for yourself.
