Using Your Mac As A Wireless Router
It has been awhile since I have seen this done, but I am looking at setting up my G5 iMac ro do this, so I can feed the Internet to two G3 iMacs in my home.
This web site tells how to do it with the following needed:
1) A cable or DSL modem, which typically provided by your internet service provider; 2) a Mac (with built-in Airport wireless) which is connected to your modem via an ethernet cable
3) any number of laptops which have wireless capability.
This listed is followed with a step by step instructions.
Be sure to read the comments to see some limitations.
