I want to use my touch at work but I do not have a wireless router there. I do have a mac pro though and a cat5 connection. So I have 2 questions. First, can I use the Airport on my mac pro to "broadcast" my connection to my touch. Second, can I buy a wireless router (802.11g) and connect it to the cat5 cable that goes into the back of my mac pro from our router and send the signal from there? Any help would be appreciated.
