Does an apple power book g4 have wireless internet?

There were several versions of the G4 PowerBooks between their launch in 2001 and discontinuation in 2006. The early ones did not have built in Wi-Fi support (known as AirPort on Macs) but it could be added as an option. The later models came with AirPort built-in. To check an individual computer select About This Mac from the Apple menu (top left) and click the More Info... button. If an AirPort card is fitted its details will be listed in the Network section.
