Frequent Disconnect/Reconnect

Just leaving some of my Dominos connected, and having my PC connected to one of them, I’m seeing frequent Disconnect/Reconnect during the day ?
Is there any reason ?

do you mean via wifi or cable?

When your pc have power control, e.g. turn off Ethernet or wifi, it will disconnect temporary.

I means that Domino is standalone on an USB power supply about 20 feet away from PC, the PC Wifi is connected to the Domino, and maybe 4 or 5 time during the day, the Wifi Manager of the PC is showing a popup that there is a disconnect and it is reconnecting automatically within 2 or 3 seconds.
So, it is some kind of temporary dropout.
(When my PC Wifi is connected to my DLink router, it is never doing such dropout)
