Hi @sns I'm on the latest Monterey 12.2.1. I've shut down any processes I could think of in System Settings. Are there others I should stop? As a side note, I tried my setup on a new MacMini and had the same issues, so it's either something in Mac OS, or my network. Network setup is Modem > Nighthawk AX4200 Router > TL-sg2210p Swtich > Mac Mini. My opticalRendu is connected via fiber to the same switch as the mini.
