im sorry i should have included more information. My g4 doesnt have a airport slot. Its 400 mhz g4 with the blueish tower. I have a cable connection to my main computer which is a dell. I bought a belkin wireless router which said it was for mac and pc, so i bought the wireless adapter card thinking it would work and its for pc only. Is there any companies that make a wireless pci card for macs or do i have to get the airport card and does the airport card work with any wireless router. Sorry if these questions are stupid but like i said i have zilch for knowledge when it comes to wireless internet. thanks inadvance for anyones help<br><br>
