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
