How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?
I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.
Mac Pro, Mac OS X (10.6.8)
