What was the work around?
Well, there are the two known WiFi networks the Media Link works with, named on the TV screen:
1: the name of the WiFi home network
2: "HTC Portable Hotspot".
When I reset the ML (press button for 10 secs) then appears a third WiFi network, named on the TV screen:
3: "Media Link HD [xxxx]".
I looked in the phone's WiFi settings and there was "Media Link HD [xxxx]" available.
I choose this WiFi network, password "1234567890HTC", and was been connected to it.
Then a strange thing had happened: On the TV screen the WiFi network switched to the home network's.
So, I switched the phone's WiFi also to home network's.
Then, and this may be important, I saved in the phone's ML settings before I connected the phone to the ML.
Then I connected the phone to the ML and after some time, needed for configuration, phone and ML was connected via WiFi home network
I disconnected and reconnected a few time and always the connection was via WiFi home network, without any delay for reconfigations.
Hope my clumsy discription is somewhat understandably ...
