Teamspeak3 server packet loss

Hello,

Im hosting my own TS3-server at home and the server is connected to a switch, which is then connected to my router with a speed of 1000/1000.

The issue that I’m having is that no matter on which device I download something at home, all users connected to my TS3-server will have around 15% packet loss, which is really noticeable. I know that if I max out my network speed, the TS3-server will take a hit. But the thing is that the problem occurs even if I download something in 40mb/s. As soon as I pause the download, all users are back to 0.02% packet loss as normal.

Any ideas on what could be causing this? All QoS settings are turned off on my router.
