Yes, that might help.
However, I have altogether 24 devices, including switches, electric plugs, synology servers etc. etc. So no.

I am just thinking what happened since last time it was working.

And the main thing is a new iPad. But why so ?

After this was a cascade of switches, the last one being a Buffalo. I took the Buffalo off. Hooray, my iPad was no longer disconnected.

Except that it lasted 3 days. At the end of the third day, back to square one; the iPad regularly loosing the rendered, and without any change on my network.

In a nutshell: UPnP is a rubish protocol. Comparing to DHCP as an exemple: I never had any issue with DHCP. I keep on having issues with UPnP
