What is QoS on a router and should you turn it on?

QoS stands for Quality of Service — it's a feature that lets your router give internet priority to certain devices or activities. Turn it on if multiple people share your internet and you want video calls or gaming to stay fast while others are streaming.

QoS is like a traffic cop for your internet. When many people are using the connection at once, it lets you decide who gets priority. Work calls and video conferences can jump ahead of a download. It's most useful in a busy home or office where internet gets slow when everyone's online.
