Summary

Here are the key points to remember from this chapter:

• Networks sound complicated, but they are really simple to understand when you realize that they are made up of small building blocks that are all more or less the same.

• You can create entirely Wi-Fi wireless networks or add Wi-Fi wireless capabilities to an existing network.

• In most cases, you'll want your Wi-Fi network nodes to connect to ordinary DSL or cable modem Internet access.

• It's inexpensive to put together a Wi-Fi network or to add Wi-Fi capabilities to an existing network.
