Explanation
QoS (Quality of Service) allows a router to prioritize certain types of network traffic - such as video streaming - over lower-priority traffic like downloads or browsing. When multiple users compete for bandwidth, QoS ensures that the streaming video receives the minimum bandwidth it needs to play smoothly. Disabling SSID broadcast hides the network name but does nothing to improve bandwidth allocation. UPnP (Universal Plug and Play) helps devices discover each other but does not manage traffic priority. DMZ (Demilitarized Zone) exposes a device to the internet without a firewall - it is a security configuration, not a bandwidth management tool.
