Well, perhaps it is a batch of them with the issue, but obviously by the number of people posting here with the issue, it is an issue indeed, no denying that.
Another thing to test for those of you without the WiFi issue at home is to test it out on different WiFi services outside of your home, because you may not be experiencing the issue at home, but you could on different routers...
My experience with Apple so far is a mix bag, I bought an iPod for my son that after a couple of months began to overheat to the point of burning, but local Apple store Customer Service was excellent and his iPod Touch 4G got replaced without questions, I just bought another one for my daughter, so far so good. Now I decided to purchase the New iPad for myself, lured by the positive critique on the beautiful screen and colors it renders, but now I also read about a "yellowish tint to it" , that along with the Wifi issue being discussed here honestly has me concerned over my purchase. I am hoping for a response from Apple to the WiFi issue, but I will probably stick with my purchase, however, if any of this mentioned issues is present on my New iPad, it is going back, I sure hope not because I am excited about it , some of the music producing apps are awesome....
