It never works as well via wi-fi, even when it's right next to the router with about 500mb/s. You still get the odd glitch on the WiFi.
Must admit I’ve not had any issues but I didn’t use the erros, went with my own wifi6 router so maybe that helps? Haven’t played game pass much (forgot I had it tbh so thanks for the reminder!) but GeForce now was ok on Wi-Fi. Hard wired always best of course.
Wi-Fi 6 gives cracking speeds on Wi-Fi - just there (same room as router) : 769 down 732 up and 11ms ping. If I want to properly flex the muscles of the connection is has to be hard wired mind, never gonna get Wi-Fi speeds to saturate that for a while!
