Is UPnP a rubish protocol ???

this is what I found “ 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 adequate for most home networks.”
… each switch is a hop and Wi-Fi access point is a hop too … think about it

Hmm, so you mean there is an impact on the number of hops on the UPnP protocol.

That I should investigate; it could explain. Question: when the renderer and the server are on the same switch, but this switch is 3 hops to the router. How do you compute the number of hops in this case ?

After what you wrote, I would be ashamed to describe to you my network architecture ;-)
