Using an iPad has few challenges, like for example finding some help when things do not work how they supposed to. For example, my iPad stopped to show my location when I was connected via WiFi. Google showed me that it was a common issue reported in Apple's official forum but without an Apple's official answer. May be because Jobs still on medical leave and without him nobody else can determine if the issue is really an issue or simply that the user does not know how to use the iPad.
After a lot of digging, I found somebody in one of those fan forums that I'm not linking just because after applying the solution I could not find the link anymore explaining what to do. Simple, go to Settings, General, Reset, Location. After that, turn off the iPad completely, by holding the Power button for few seconds and then sliding the Off bar. Once you turn on the iPad, your WiFi location should work again.
The cause... Who knows...
