Entered on iPad 2 repair a peeling-screen virtually non-working Wi-Fi.
Proceed to disassembly and see what's the matter.
First you need to peel a touch screen. If it fits well, it must be warm and to hook around the perimeter of a thin plastic spatula. The author of these lines use a regular plastic card, slightly grind it to the one end it has become acute.
It's quite difficult and not a quick operation that requires caution. So do not rush, peel off gently-the sensor is large and thin, it is not difficult to break. And still glued to the screen of the wireless antenna and Bluetooth, which is also bolted to the hull in two places. Otkleivaya, it can break. It is Wi-Fi-antenna slightly to the right front of the round button with a picture of squares.
Flex sensor located on the left side of the screen below. This is not to tear. When the screen is peeled off-turn down it.
In this case, the screen before someone changes and to separate the sensor took less than a minute. As mentioned above, the screen is already partially unstuck.
Some photos of any parts of the perimeter:
