@oliof I really thought about that... but makes no sense does it? I tell you why. Yesterday my desktop computer died and believe it or not, I took my new laptop and connected via wifi to my router at home and no disconnect issues anymore.
This leads me to the following. The network card must have had a glitch or the port on the switch which my desktop was connected. Strange thing about is that no other connection was showing problems, only those to the printer. I also connected via a desktop switch... no difference.
Anyways thanks for the engagement. I was so suprised that for such a long time it must have had to sit and wait and all of a sudden a major problem solved, without DUET2 interaction.
All the best
