Airport Is Screwy

Hello, I'm new here.

My macbook is having some airport problems. When it is plugged into its power source (charging), it runs on the internet perfectly. When the power source is unplugged my macbook says it's connected to the internet but it doesn't load any pages. Is this a problem with my macbook or my wireless router?

Please help

It's most likely a problem with the wireless router. Try unplugging your router then plugging it back in again.
