(
UPnP
) is a set of networking protocols which enables network devices to communicate and automatically establish
working configurations with each other, such as computers, printers, mobile devices etc.
It’s typically used for data sharing, communications and entertainment purposes, although sometimes not preferred, due to security concerns.
Some devices may require UPnP to be enabled to function properly. Use the switch to set UPnP to active or inactive, according to your
requirements.
