Thanks, Giga, but my iPad is connected via WiFi router and CAT5 to the Qu-16 Network. I also do not witness any disconnection.
With your iPad connected to the routers WIFI, when you open the QU Pad mix APP does
QU SB show up in the white box in the center of the screen.
On the router what port do you the mixer plugged into, it should be in one of the LAN ports (usually four of them together in a row) and not plugged into the WAN port (sometimes a different color jack and away the from the other jacks.
On the mixer the plug into the network jack not the D Snake jack.
It looks like your were responding as I was typing this post.
