My Wife has had a problem with her 4th Generation Ipad that wherever she connects wirelessly she has frequent disconnects as where my 3rd Generation Ipad stays connected in the same room or location. My question is; Is there some internal sensitivity adjustment in the Ipad 4th Generation circuitry to increase the wifi receiver sensitivity to stop the disconnects? Or does anyone have any suggestions as to how to remedy this problem. The Ipad is up to date on all updates. Thank you.
