I have a 32 g WIFI IPAD 2, I am able to connect via Wifi at home just fine. I am even able to connect on someone else's wifi in my building even though it shows as two bars as signal it seems to be just fine as well. But if I am in public like a park or public space where they have wifi I have so much trouble connecting even when it shows it has 3 bars? And when it does connect the connection can be really slow, am I doing something wrong is this a known issue, do I have to be really close to the access point or is there a lag because so many people are using the connection at once?
