Another couple of questions..

8) On a system showing the problem, during the 25 seconds that the connection IS present, does the 218 respond to commands from the app? For example, if the volume or source is changed, does the display on the app show the change?

9) Do you still get the same issue if you reconfigure your router or Wi-Fi Access Point to use another channel or band (2.4Ghz or 5Ghz)
