• Advertisement Time To Live. The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. A hop is the number of steps allowed to propagate for each
UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The
default value for the advertisement time to live is 4 hops, which should be fine for most home
networks. If you notice that some devices are not being updated or reached correctly, then it
may be necessary to increase this value a little.
