Ethernet switch with QOS

Hi

I am looking for a cheap solution that provides a way of limiting traffic speed to Netflix in particular as my daughter swallows up all the bandwidth when watching Netflix.
Or is there another alternative (besides not letting her watch Netflix)

Thanks.

I am using the talktalk HG633 router on my fibre.
I can't see anything in there that will do what I want.
Can you recommend a router?
