I'm running Steamlink on my RPI4 4GB, and the wired connection report is absolutely awful. It reports 3-10Mbps. When I switch to Wi-Fi it reports 50+, but obviously Wi-Fi has its own problems.

I have tried redoing my home network but to no avail, I can't get it to work better over ethernet. My setup is currently like this.

Router + Pi <------ Powerline ------> Network Switch + PC

I ran iperf3 as well, and it reports 90Mbps+.

I honestly have no clue what's happening, anyone have any ideas?
