Re: Ipad can't maintain Wifi connection despite of strong signal
The default procedure which is suggested by the Apple website to connect to the Wifi network creates the problem which you are facing. I also have the same model of Ipad and was suffering from the disconnection problem. I figured out the solution to the problem. Do not connect to the Wifi network using the default method, instead just turn the Wifi on and then click on Home button on Safari. Now type the URL of the website which you want to visit and click on GO. Now the browser will ask for connecting to the network, provide required information and you will not face the disconnection problem.
