I do understand, that streaming video will have some effect on internet performance of other computer's connected to the same router. However, when I am watching YouTube videos, which I understand not to be at bandwidth hogging as say Netflix, other streaming sources, or using a torrent client with multiple connection, my wife's computer internet connection bogs down to a point where it's basically unusable. It becomes quite contentious around here when I have to give up watching Safari Live on YouTube so she can play games on Facebook.
My computer is an Intel Core i7 6700K @ 4.00GHZ, with 16GB Dual-Channel RAM at 1066MHz on a GigaGyte Z170XP-SLI-CF motherboard. I am am wired directly between the onboard ethernet controller and the ISP provided Hitron CGN3ACSMR modem. My wife is connected direct to the same modem. Our ISP claims 100Mbps download and 10Mbps upload. I consistently get decent results, sometimes exceeding with speed.
My question ... is there any reason why my wife's computer would suffer such internet instability while I am say streaming a YouTube video? Are there any settings that may be overlooked, or something to consider as a bottleneck?
Thank you ...
