What sort of Mac does she have?
What OS is it running. The details are required before I could tell you exactly if, or how, to fix it up. Configuring a Mac for wireless is very easy as long as it is capable of accepting an Airport card. If it is a newer one it will accept the Airport card and go wireless.
You will need a wireless router to handle all the machines. I guess you will also be using the 2 wire from SBC as your ISP in the new place. Connect the 2Wire modem to the wireless router with the Ethernet cable. if your machine is close to the router, connect to it using cat 5 cable.
All the other machines can go wireless, distance permitting.
Hope this help
I have a Sony laptop that is connected to a 2WIRE modem for its DSL connection. My ISP is SBC. I'm moving to a new place. My future landlord, who lives on a second story of my new residence, wants to share my DSL connection. She has two or three computers, two of which are PC's and one Mac. She uses dial up at the moment. What does she need to buy in order to share my DSL connection? For example, does she have to buy a wireless card? If so, which one? How do you configure a Mac for a wireless connection? I know very little about Macs. Thank you beforehand for all replies.
