Are you using the sense app only or have you tried to connect going through the Innuos website direct (no app)? I had to use the Innuos website direct for my pixelbook to connect the Zen Mk3 as advised by Innuos Tech Support. Then I bookmarked it, named and saved it, and click on that to connect, not the app. Other than that, and I am pretty sure you have gone thru all the basics, but try this sequence. 1) remove and replug the Ethernet cable at both ends assuring it is secure at both ends and consider trying another Ethernet cable if the first round of these 5 steps does not work. (2) shut down the mini and unplug it. (3) reboot both the modem and router. (4) reboot your device. (5) plug in the mini, turn it on. If using the website and going thru reboot process above doesn't work, suggest contacting Innuos.
