In This Chapter
Finding out how Internet sharing works
Choosing between hardware and software Internet sharing
Connecting your Macs to a cable/DSL router
Adding wireless support to a shared Internet connection
Although in previous chapters I discuss lots of fun stuff that you can do with your network, my favorite networking activity is sharing a single Internet connection among all the computers on your network. Without sharing, only a single computer can connect to the Internet at once (imagine the dilemma that pops up whenever more than one person wants or needs to surf the web at the same time).
Luckily, because small home and office local area networks (LANs) use our old friend TCP/IP for network communications, connecting an entire network to the Internet isn’t as troublesome a task as you might think. In this chapter, I talk about different hardware and software options for sharing your Internet connection as well as how to include your wireless devices. (Read Chapter 1 of this minibook for the lowdown on TCP/IP and LANs.)
