Internet disconnects when unplugged from power?

[Total Immortal]

My PowerBook is doing something odd. When I either pull the power cord out of the computer, OR plug it back into the power, all the internet connections stop. It SAYS that it is still connected to the internet, but my chat programs stop responding, and by web browser stops working until I restart my computer. It just recently started doing this. Does anyone know what could be causing this? Thanks.
