Can torrents choke a switch?

[sittingduck]

I have two PCs connected to a switch, which is again connected to an Asus RT-AC68U (about to be replaced) in the attic running Merlin. My son was gaming on one pc, when I started downloading a torrent on the other. This resulted in his ping rising from 20 to about 500. This never happens if I download a torrent wirelessly from my laptop. We have a nice 300/300 fiber connection. Could this ping spike be caused by the switch not being able to prioritize his traffic? I have this unmanaged switch: https://www.dlink.com/dk/da/products/dgs-105-5-port-gigabit-ethernet-switch - is it a POS? I always thought that a switch was unnoticeable - it just works, but maybe I'm wrong? Any input appreciated.

Not the switch but the router QOS not working for wired connections.

Holy smokes - didn't think about that. Will take a look at the settings and report back. Thanks!

May be something you can't fix. Flex QOS or Cake QOS may help. But...

I'll have a look and try things out and let you know. Thanks.
