I can verify that this happens. It happens on my older Roku 3 and on my brand spanking new one. After using a channel (usually Plex) for a while I exit back to the main menu and Roku reports "Not connected." But my Rokus really are connected and I can enter another channel or reenter Plex and everything works fine.
If I go into settings and simply highlight "Wired" and never update the connection the message goes away.
There is never any symptom I see involving my network
All my Rokus are connected wired.
I never have to refresh my connection. It just works but gives me the erroneous message that I am not connected.
I have seen this for a while (weeks not months) but it never had an adverse impact on operation but when I saw this thread I thought I should report that I see the problem as well and it is completely reproducible.
Two Roku Ultras, three Roku 3s and a Roku 1
