Hi guys I need some help. My whole family uses the same router and when I try to play online games I encounter high ping due to my brother and sister watching Netflix, Youtube etc. I did some research and found that this problem may be prevented with QoS. But when I connected the router's interface, those options looked so complicated compared to other routers interfaces that I found on the internet. Could anyone help me figure this out? Thanks.
