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.
