Bought my switch 2, had it on Ethernet and it would drop connection randomly and thus dc me from matches. My network is rock solid for everything else on that Ethernet switch and my switch 1 with a usb Ethernet adapter didn't have issues.
Only my switch 2 on Ethernet did. That said, I switched to WiFi and the issue went away. I am probably not going to bother with Ethernet again because WiFi on the switch 2 is much better. It can handle channels above 149 for instance. The switch 1 could not, at least not the og release. Oled might have an improved chip but never checked as my wife was the one with that and not myself.
