The fact that I had 7 solid months of continuos wifi signal strength on my ipad2 compared to the roller coaster ride ipad3 signal strength now is about enough proof that I need to exchange this device. I love this new iPad even with the fluctuating signals. The first two weeks were strong and crisp. The following weeks were constant weakness. It likes my Linksys router much better than Net gears. The last 2 or 3 weeks have been super fast operation. It's hard to decide what to do with the device. Applecant say an exchange will be 100% better always. Can't say I'm reading people's exchanges getting it done.imo this is a black eye for this device that Steve Jobs would not be good with. All Apple has stated is that they do exchanges. Somewhat vauge .i really wish I had not sold my ip2. It just worked.
