My Wi-Fi has no internet connection?

So I'm on my iPhone (using 3G to be on safari right now) using my Wi-Fi when all the sudden there's no internet? I checked the router and re plugged in the router, and i shut down my phone and restarted it to no avail. I really don't want to use up all my 3G so I'm hoping you can help solve this issue of the strong wireless connection but lack of internet?

It depends on where you are now. I think the device that you are using is okay.

Find some place that people usually use 3G.
