Set up wireless speed with Net Limiter

Anyone knows how can I set a limit on the wireless I got at home by using Net Limiter please ?
The issue is that I got my pc connected with cable and my sister connects to the wifi to use internet and when she does my internet literally dies. I finish downloading with 200kb/s max when normally I download with 1.5 mb/s
I know I had did it before but can’t remember how so any help is appreciated
Thanks in advance !

Upgrade your connection and enable QoS.
Alternatively you could just kill your sister.
Answer #4
QoS is just for giving certain speed to desired applications and not limit the router/wireless speed….
