I have 1 iMac running OSX 10.1.5 with 1 ethernet port, 1 laptop running windows 2000 professional with 1 ethernet port and 1 laptop running windows 98 with 1 ethernet port. I would like these to share a cable broadband connection that is currently hooked up to the imac via ethernet (Modem only has one port). Ideally I would like the laptops connected wirelessly, is any of this possible, if so, how???
