See this question for details of how to check wifi status.

Do be aware that even if the wifi is switched on, and connected to a wifi network, that doesn't guarantee data can be transmitted and received - the signal may be too weak for example at the moment you try to use it. So don't assume connections will definitely work because the wifi is connected.

Take a look at WifiManager class.

Also here is a nice article with code samples.

I use a super class that I extend all Activity classes from. It shows an alert when connectivity is lost and stays that way until connectivity is restored. You can edit it to add anything you want.
