How to connect Mac Powerbook G3 to internet via my router
I have a BT Wireless Network 1250 router to which one PC is connected physically and another PC connects using a USB Netgear adaptor. I want to also connect a Powerbook G3 but am told it is too old a machine to take an airport card. I have tried plugging it in physically to the router but no luck. I keep getting 'error -50'. The internet connection wizard is asking me to put in IP address and domain name and all sorts of other information that I am not sure about. Is there an easy way of doing this? Can I buy any sort of adaptor like the one I have for my PC which hopefully would detect the signal automatically?
Thanks.
