I remember having this issue, it was really annoying being forced to use the new iPad, only in the same room as my wifi router due to the poor range. I spent quite a bit of time researching for a solution, without any luck. All of the methods I found didn't work for me. Right when I lost all hope, I came across WIRED magazine and found a review of Pong Research cases, after looking at the great feedback on their products, I decided to place my order, to finally put and end to the problem.
