I-Pad 1 Problem

[inquisition]

My I pad wont stay connected to the web or email, it finds address or site but after a minute screen goes blank.
Is there a diagnostic tool installed on the i-Pad 1 please?
Thank you

Hi Inquisition, my iPhone has started to lose connection to WiFi since I upgraded to iOS7. I have Googled the issue but have not yet found a fix :(

Go to settings, wifi then touch your wifi name. On the next screen touch Forget this Network. Wait a few seconds and then rejoin your network
