As a somewhat sad and ridiculous conclusion, it seems that the most certain way to get iPad to connect via wifi to Internet is to replace your current router with a new one — made by Apple, of course. I ran out of options with my Belkin N+ Wireless Router, at least. It was possible to open the network and leave it totally unprotected – iPad accepted it only then – but I did not prefer to have it set up that way. So, Cupertino, here we go again (AirPort Express works fine with iPad & iPhone, of course). This must be part of Apple’s not-so-secret plan of world domination?
