I agree with your analysis, I would just add that this behaviour happens
for me at home, but not in most other "professionally managed" wireless
networks.  This makes me think that it might be a network configuration
derived issue — but I have not been able to get to the bottom of this
yet…

I see that you might be based in Belgium — I am too, and my home network
uses most of the defaults from Proximus' B-Box 2.  If this is the case
for you too, then perhaps it is a matter of the default settings in that
router?

Best wishes,

Alex
