However, if you are going to connect your LAN to the Internet, an AP is required to connect the LAN to the cable/DSL modem or another Internet connection.

If your AP does not include an Ethernet switch, you can connect the AP to an unused port on an existing Ethernet switch. Whether an AP has an integrated Ethernet switch or the AP is connected to an existing switch, wired and wireless clients can be part of the same network. By configuring wired and wireless clients with the same workgroup
