Thanks a lot, Salvatore! Your response has been really quick, informative and useful.
I'm under the impression that the issue with the Wi-Fi connection pre-dates the upgrade in which I detected this warning - and so it would be non-related and calling for a merge - , but still not sure. I'll try to test the connection to find the cause of the problem. Any hint about how/with which tool could I do that? Thanks again, best regards.
