To be honest I am very surprised by some posts in this thread from people that are saying that the "i" products roam very well in their projects. Even apple admitted the ipad wifi problems and I have validated my own findings with other pros.

So for people that managed the roaming can you expand? APs of use? Do you use the same channel or not? Do you have more than 2 APs in the succesful projects and are you sure the device roams i.e there is overlap of wifi signal from AP to AP and not looses signal as you walk and then reconnects to the next AP? Also how many projects have you seen succesful roaming?
