This is heavily dependend on your hardware. In June I visited Australia, and technically speaking it was a nightmare using an iPhone5 (Greyhound Buses worked 80% of the time, Hostels like 30%). All Android users had a much better Wifi experience. Now back here in Berlin I see the same trend. I started a new job and I am staying each week in a different hotel. I just got an Nexus 5, and when I compare it next to my iPhone 5 in the same place, most of the time Android can connect to the Wifi, why the iPhone5 can't. Speed of course is a complete different story. I am wondering if this is an iPhone5 or iOS issue in general.
