My take on this is that there are clearly a lot of people suffering from the same issue ( myself included), and people should NOT be having to change this setting, change that setting, contact your router provider, go to a static IP......
It is abundently clear that there is a flaw in the wifi of certain Sony phones.
Now, in my mind, smart phones are a fundamental way of life on the whole, so the internet connection needs to be rock solid, and also the software that makes this so.
Sony have failed miserably in their efforts (lack of?) to acknowledge and fix this problem, and so this makes their product not fit for purpose.
If they cannot offer a product that gives what every other device gives seamlessly, across many manufacturers, then they do not deserve to be considered manufacturers of reliable devices worth having.
Spread the word across social media, it may have the desired effect....
